Summary
What is REACH?
REACH is the main EU legislation for the regulation of chemicals in the EU (the
Registration, Evaluation, Authorisation and Restriction of Chemicals Regulation). It is a
single market measure applying in the European Economic Area (EEA), which includes the
EU in addition to Norway, Iceland and Lichtenstein.
REACH requires substances that are manufactured in or imported into the EEA to be
registered with the European Chemicals Agency (ECHA). It then provides a regulatory
framework to control or restrict the use of hazardous substances based on those
registrations.
REACH is important for improving the protection of human health and the environment
from hazardous chemicals and for facilitating trade in chemicals across the single market.
The UK chemical industry
The chemical industry is a key manufacturing sector in the UK, accounting for 9% of total
UK goods exports. Trade in chemicals is highly intertwined with the EU; 57% of chemical
exports in 2018 went to EU Member states, and 72% of chemical imports came from the
EU. Further, chemical products are used in many other manufacturing sectors.
Brexit implications and challenges
REACH is an example of EU legislation that is not straightforward to copy across into UK
law. This is because the regulation relies on the integrated role of the ECHA and is closely
tied to the single market.
REACH is a regulatory requirement for trade that impacts many UK manufacturing sectors
that rely on chemicals. Manufacturing industries often have complex supply chains with
chemicals crossing UK-EU borders many times.
REACH in the transition period
Following the UK’s withdrawal from the EU on 31 January 2020, REACH continues to
have effect in the UK until the end of the transition (or implementation) period according
to the Withdrawal Agreement. However, the HSE will no longer participate in ECHA
decision making.
REACH after the transition period?
The UK Government has stated that the UK would not participate in the EHCA or the EU
regulatory framework for chemicals after the transition period. Instead the Government
proposes to put in place a separate UK REACH regime. Chemical and manufacturing
industry stakeholders continue to call for an agreement with the EU that ensures
frictionless trade and regulatory consistency, ideally as close as possible alignment to
REACH. The Government has proposed that the agreement could include an annex on
chemicals with provisions for data sharing and cooperation.
A UK REACH
REACH would be retained in domestic legislation at the end of the transition period
(currently expected to be 31 December 2020). Secondary legislation has been passed that
would amend REACH in the UK to make it work in a UK-only context from that point.
The UK REACH Regime was initially designed to establish a UK-wide market for chemicals
applying to all chemical substances manufactured and imported into the UK. The Health
4 End of Brexit transition: chemicals regulation (REACH)

and Safety Executive (HSE) would be established as the UK Chemicals Authority, taking
over the functions of the ECHA. Under the Northern Ireland Protocol, however, the EU
REACH Regulation will continue to apply to Northern Ireland after the end of the
transition period, while UK REACH will regulate the access of substances to the market in
Great Britain, as set out in the REACH etc. (Amendment etc.) (EU Exit) Regulations 2020.
The Government says that the proposed UK REACH regime replicates the EU system as
closely as possible, maintaining the fundamental aims and purposes of REACH including
high standards of health and environmental protection. However, industry and
environmental stakeholders have raised concerns that the UK REACH regime is not
workable in practice, would be costly for industry and lacks transparency.
The Environment Bill 2019-21 contains provisions that would give the Secretary of State
powers to amend the UK REACH regime with the exception of certain listed protected
provisions.

1. What is REACH?
REACH – the Registration, Evaluation, Authorisation and Restriction of
Chemicals Regulation (No 1907/2006) – is the main EU legislation for
the regulation of chemicals in the EU. 1 It is a single market measure that
applies throughout the European Economic Area (EEA), this means EU
Member States as well as Norway, Iceland and Lichtenstein.
REACH requires substances that are manufactured in, or imported into,
the EEA to be registered with the European Chemicals Agency (ECHA),
along with safety information about the chemical and its uses. 2 This is
referred to as the “no data, no market” principle – without providing
the necessary safety data, companies cannot place their products on the
market. REACH then provides a system for controlling or restricting the
use of hazardous substances based on this data (see section 1.2).
REACH has several aims, including:
• to protect human health and the environment from the risks that
can be posed by chemicals;
• to place responsibility onto industry (manufacturers and importers
of chemicals) for understanding and managing the risks
associated with the use of chemicals;
• to allow free movement of chemicals and substances in the EEA
market, while also enhancing innovation and competitiveness in
industry;
• to minimise animal testing by promoting the use of alternative
methods of safety assessment and by facilitating data sharing of
testing results. 3
REACH is managed by the European Chemicals Agency (ECHA), based
in Helsinki. The Health and Safety Executive (HSE) is the enforcing
authority in the UK, and the Department of Environment, Food and
Rural Affairs (Defra) is the lead Government department with overall
policy responsibility across the UK.
How were chemicals regulated before REACH?
REACH came into force in June 2007. Prior to REACH, chemicals
regulation across the single market was a patchwork of different
regulations with different rules for “new” and “existing” chemicals. 4
REACH was developed to have a single system of rules for all chemicals
across the single market. Significantly, REACH placed the burden of
undertaking risk assessments for substances onto industry, rather than
on public bodies. 5

There is also specific EU legislation for certain types of chemicals (such as biocides
and cosmetics) and for the labelling and packaging of chemicals. For background
information, see the Library briefing paper: Chemicals Regulation (11 August 2016).

1.1 Why is REACH significant?

The chemical industry is an important manufacturing industry in the UK
(see Section 2). Chemical substances also feed into the supply chains of
many other manufacturing sectors. More than 22,000 substances are
registered under REACH. 6 This includes substances that are used in key
UK manufacturing sectors, such as the aerospace, automotive and
pharmaceutical sectors. It also includes substances used in the
manufacture of everyday products such as cleaning fluids, paints,
plastics, fabrics and electronics. Trade in chemicals is highly integrated
within the single market and complex supply chains mean that products
often cross borders multiple times.
In addition to its importance to trade, REACH regulates the safe use of
chemicals to minimise harm to human health and the environment by
providing a framework under which the use of harmful substances can
be restricted. 7 REACH also plays a role in keeping animal testing to a
minimum, by requiring that animal testing can only be used to meet
registration requirements as a last resort and by facilitating data sharing
of testing results (see Box 1). 8

1.2 How does REACH work?

Registration
Companies are required to register substances that they manufacture or
import into the EEA (in quantities of more than 1 tonne). The
registration (called a registration dossier) must provide information
about the properties and hazards of the substance, and any risk
management measures associated with its use. The dossier must be
supported by scientific evidence such as the results of safety testing
experiments.
REACH is based on the “one substance one registration” principle. 9 This
means that companies must submit joint registrations where they are
manufacturing/importing the same substance, including sharing access
to testing data (Box 1).
As of 14 February 2020, UK companies held 8995 EU REACH
registrations (9% of total), encompassing 4898 substances (21%) and
1350 companies (8%). 10

Box 1: Data sharing under REACH

Registrants are expected to share safety and testing data needed for registration to avoid
duplicate/unnecessary testing. This plays an important role in minimising the number of animal testing
experiments carried out. 11
REACH requires registrants to make every effort to reach an agreement on sharing data. Firms
negotiate and purchase access to the data required to support their REACH registrations; often this
means the right to refer to the data in the registration dossier (through a Letter of Access), not full
access to the data. REACH requires that the costs for sharing information for a registration are
determined in a “fair, transparent and non-discriminatory way”. 12
The ECHA webpages and guidance on data sharing provides more information.

Evaluation, authorisation and restriction

REACH provides a framework for banning or restricting the use of
hazardous chemicals if risks cannot be managed.
National authorities (the HSE in the UK) evaluate registration dossiers For further
and identify substances for which regulatory action should be prioritised information see:
by the ECHA.
Understanding REACH
Some examples of regulatory action include: (ECHA)
• Substances may be added to the Candidate List of Substances of
Very High Concern (SVHC) which carries additional reporting REACH Explained
responsibilities and may lead to further regulatory action. 13 (HSE)

• Substances placed on the “Authorisation List” require an

“authorisation” decision from the European Commission to use
the substance for a particular purpose. Substances requiring
authorisation are listed in Annex XIV of REACH.
• Substances considered to pose risks requiring EU-wide action can
be “restricted”. Restrictions can take many forms, for example a
total ban on a substance, bans on certain uses or concentrations,
or requirements for technical measures or specific labelling.
Restrictions are listed in Annex XVII of REACH.
ECHA committees and decision making
There are several ECHA scientific sub-committees that inform the
ECHA’s decision making and advice to the European Commission. For
example, the Committee for Risk Assessment, the Member State
Committee and the Committee for Socio-economic Analysis. 14
Most decisions for regulatory action under REACH – for example
whether a substance should be restricted or subject to authorisation –
are taken by the European Commission considering the advice of the
ECHA and following consultation with Member States, the European
Parliament and Council. Some decisions are taken by the ECHA directly,
for example, to classify a substance as a SVHC.

8 End of Brexit transition: chemicals regulation (REACH)

1.3 How do non-EEA countries trade

chemicals with the EU?
Only companies registered/based in EEA Member States can register
substances directly with the ECHA. Companies in non-EEA countries
that wish to trade chemicals with the EEA market have the option to
nominate an “only representative” agent registered in an EEA country
to take over the responsibility of complying with REACH on their
behalf. 15 Alternatively, the obligation for compliance with REACH will
fall to the importer of the substance to the EEA.
Switzerland 16 and Turkey 17 (where REACH does not apply) have enacted
legislation that mirrors REACH but is developed and implemented
separately in those countries. Swiss and Turkish companies wanting to
sell products in the EEA market must still comply with REACH (as
explained in the above paragraph).
The ECHA has “cooperation agreements” with regulatory agencies in
Australia, Canada, Switzerland, Japan and the USA, which support
exchanging information, best practice and knowledge regarding the
management of chemicals (but not confidential business information). 18

3. REACH and the transition

period
3.1 REACH and the Withdrawal Agreement
The UK left the EU on 31 January 2020 on the terms of the Withdrawal
Agreement agreed between the EU and the Johnson Government in
October 2019. The Withdrawal Agreement was implemented in UK law
by the EU (Withdrawal Agreement) Act 2020.
Under the Withdrawal Agreement, REACH continues to have effect in
UK law until the end of the transition period (also called the
implementation period), currently set to run until 31 December 2020.
This means that UK companies can continue to register chemicals with
the ECHA and registrations and authorisations remain valid in both the
UK and EU markets during this time. However, the UK no longer
participates in meetings or decision-making of the ECHA and the HSE
no longer acts as a leading authority to conduct assessments under
REACH. 25
The following Library papers provide further information about the
Withdrawal Agreement in general terms:
• The October 2019 EU UK Withdrawal Agreement, 18 October
2019
• Constitutional implications of the Withdrawal Agreement
legislation, 20 February 2020.
For discussion on whether the transition period can be extended, see
the Library Insight: Coronavirus: Is it possible to extend the Brexit
transition period? 20 April 2020

3.2 Protocol on Ireland/Northern Ireland

The Protocol on Ireland/Northern Ireland in the Withdrawal Agreement
sets out the arrangements that would take place to maintain an open
border between Northern Ireland and Ireland, if the UK and EU are
unable to conclude a new future relationship agreement by the end of
the transition period. The Library briefing paper on the Withdrawal
Agreement explains the Protocol in detail.
Under the Protocol, Northern Ireland would remain mostly aligned to the
EU’s regulations for goods at the end of the transition period, including
REACH. 26 This means that EU REACH would continue to apply in Northern
Ireland at the end of the transition period even if a separate UK-based
regime applied in the UK. The REACH etc. (Amendment etc.) (EU Exit)
Regulations 2020, approved by both the Commons and Lords in early
December 2020, implements the Northern Ireland Protocol by enabling

25
Withdrawal Agreement, Article 128(6). HSE, Regulating chemicals (REACH) during
the transition period, accessed 18 February 2020. See also the Library briefing paper
on the October 2019 Withdrawal Agreement (18 October 2019) that describes
institutional arrangements in the transition period.
26
Article 7, Protocol on Ireland/Northern Ireland
12 End of Brexit transition: chemicals regulation (REACH)

the EU REACH regime to continue operating in Northern Ireland, as well

as providing for the continued access of Northern Ireland goods into
Great Britain (see section 5.4 below). The UK REACH regime will apply to
Great Britain (England, Scotland and Wales) only.
13 Commons Library Briefing, 17 December 2020

4. Negotiating a future
relationship
The exact nature of the UK’s chemicals regulation regime, and the
extent of any cooperation with the ECHA, after the end of the transition
period will ultimately depend on the outcome of the ongoing future
relationship negotiations between the UK and the EU. 27
For general background information, see the Library briefing paper on
The UK-EU future relationship negotiations: process and issues
(CBP8834, 2 March 2020), The UK-EU future relationship negotiations:
Level playing field (CBP 8852, 19 June 2020) and Library Insight What is
happening in the UK-EU future relationship negotiations? (7 April
2020).

4.1 Participation in the ECHA?

The Political Declaration on the future UK-EU Relationship agreed
between the Johnson Government and EU in October 2019 included a
commitment to “explore the possibility of cooperation” with the ECHA.
However, neither the UK Government nor EU opening negotiating
mandates (February 2020) refer to cooperation with the ECHA
explicitly. 28
In a February 2020 Westminster Hall debate (on regulatory divergence
and the UK chemical industry) Parliamentary Under-Secretary of State
for Defra (Victoria Prentis) stated clearly that the Government would no
longer participate in the EHCA or the EU regulatory framework for
chemicals after the transition period:
Through various emanations, we have reached a position where
we are definitely leaving the single market and the customs union,
and we will no longer participate in the ECHA or the EU
regulatory framework for chemicals. 29
She stated that the UK would establish its own chemicals regulatory
regime (UK REACH) that would retain the fundamental approach of
REACH but have the “freedom to do things differently where we
consider that in our best interest.” 30 Section 5 of this paper provides
information and commentary on the UK REACH Regime that would
come into force at the end of the transition period.
Several opposition MPs raised concerns during the debate about the
Government’s approach, highlighting that a separate regulatory
framework would negatively impact the UK chemicals industry (see
Section 4.3 below).

14 End of Brexit transition: chemicals regulation (REACH)

In November 2020, during the Lords Secondary Legislation Scrutiny

Committee's examination of the Draft REACH etc. (Amendment etc.)
(EU Exit) Regulations 2020, Defra was once again questioned on the
possibility of co-operation with ECHA and remaining within, and aligned
to, EU REACH. The Department responded:
The Government’s position on not remaining within the
jurisdiction of the European Courts of Justice (ECJ), means that we
are not seeking alignment with EU REACH or participation in the
European Chemicals Agency (ECHA). 31
The Johnson Government’s position regarding the ECHA is a change in
approach compared to Theresa May’s Government. The May
Government’s preferred approach to chemicals regulation following the
UK’s withdrawal from the EU was to agree with the EU a form of
“associate membership” or “active participation” in the ECHA (and
other EU agencies in heavily regulated sectors). 32 The May
Government’s position was welcomed by chemical industry
stakeholders 33 and by the House of Lords EU Energy and Environment
Sub-Committee in their November 2018 report on Brexit and chemicals
regulation. 34

4.2 An Annex on chemicals in the EU-UK

trade agreement?
The UK Government’s approach to the UK-EU future relationship
negotiations (February 2020) proposed that the agreement include an
Annex on chemicals. The Government proposed that the parties could
agree data sharing mechanisms in line with existing provisions in REACH
for non-EEA country cooperation as well as committing to developing a
Memorandum of Understanding to “enhance cooperation further”:
Annex on chemicals
16. This annex should facilitate trade in chemical substances and
related products and ensure high levels of protection for the
environment and human and animal health. It could provide for
cooperation between UK and EU authorities, including on
implementing the Global Harmonised System of Classification and
Labelling of Chemicals. In order to ensure high levels of protection
and to support UK and EU businesses to meet the separate
regulatory requirements of the two markets, the parties could
agree data and information sharing mechanisms, in line with the
relevant provisions set out in UK and EU regulation and existing
third-country mechanisms.
17. This annex should also include a commitment to develop a
memorandum of understanding (MOU) to enhance cooperation

further, similar to the MOUs that the European Chemicals Agency

has agreed with Australia and Canada. 35
See Section 1.3 of this paper for information about cooperation
agreements with non-EEA countries on REACH. An Annex on chemicals
(Annex 5-E) was subsequently published by the UK government in May
2020 with the aim of forming the basis for discussions on the trade,
regulation, import and export of chemicals between the EU and the UK. 36
An update provided by Defra to the Lords Secondary Legislation Scrutiny
Committee in November 2020 indicated that the proposals in the Annex
had not, to date, been welcomed by EU countries:
In February, the Government published its approach to
negotiating a future relationship with the EU. That includes a
proposal for a chemicals annex as part of the EU Free Trade
Agreement. A deal on data sharing with the EU could mitigate the
need for industry to provide full data packages.
We continue to push for it, but the EU continues to reject any
sectoral annexes. However, securing the chemicals annex is still
very much our preferred outcome. This would be in the interests
of both UK and EU businesses, including those who will want to
continue selling their chemicals into the GB market.”. 37
The main provision in REACH relevant to data sharing with non-EEA
countries is Article 120, which reads:
Article 120
Cooperation with third countries and international organisations
Notwithstanding Articles 118 and 119, information received by
the Agency under this Regulation may be disclosed to any
government or national authority of a third country or an
international organisation in accordance with an agreement
concluded between the Community and the third party concerned
under Regulation (EC) No 304/2003 of the European Parliament
and of the Council of 28 January 2003 concerning the export and
import of dangerous chemicals (1) or under Article 181a(3) of the
Treaty, provided that both the following conditions are met:
a) the purpose of the agreement is cooperation on the
implementation or management of legislation
concerning chemicals covered by this Regulation
b) the third party protects the confidential information
as mutually agreed. 38
The EU’s negotiating mandate and draft treaty text do not specifically
mention UK cooperation with the ECHA. Chemical substances are only
mentioned in the context of the EU’s proposed non-regression or “level
playing field” provisions relating to environmental protection. The draft
treaty text states that “environmental protection” includes:

4.3 Stakeholder commentary

Industry stakeholders
Both the UK and European chemical industries, and other
manufacturing industries have been clear in wanting the UK to remain
as closely aligned to REACH as possible to reduce regulatory trade
barriers. 40 Industry stakeholders argue that having separate UK and EEA-
based regulatory systems would lead to extra costs for businesses that
would compromise the competitiveness of the UK chemicals industry,
disrupt supply chains or reduce the availability of chemicals in the
UK/EEA markets. 41
In a joint position paper (PDF) published on 14 February 2020 by the UK
Chemicals Industries Association (CIA) and European chemical industry
trade body (Cefic) stated that the “immediate cost” of two regulatory
systems was “expected to be £1 billion”. 42 When asked about the
accuracy of that number during oral questions in the House of Lords in
March 2020, Defra Minister Lord Goldsmith stated that the Government
could not put a precise figure on the cost involved to businesses:
I am afraid I am not able to give a precise figure—I do not think
anyone is capable of doing so—but we have had these discussions
with industry and, as I say, with BEIS. It is the case that industry
estimates are not a million miles away from our own but we
cannot put a precise figure on them at this stage. 43
The UK Chemical Industries Association (CIA) and European chemical
industry trade body (Cefic) published their joint views on the future
relationship negotiations (PDF) on 25 February 2020. 44 The industry
called for a “deep and comprehensive free trade agreement” including
tariff and quota free trade in chemicals. The industry stated its “ideal
scenario” would be the UK remaining in the EU REACH framework as
an “active participant” in the ECHA, arguing this would be the best
outcome to avoid market disruptions and maintain high environmental,
safety and health standards:

...the UK and EU chemical industry needs an agreement that

recognises the economic and environmental logic of remaining
closely connected with regard to the REACH regulation,
addressing the safety of chemicals and their placement on the
market. Realising that ambition will be good for business, good
for jobs and good for the health and safety of European workers
and citizens on both sides of the Channel. 45
The industry welcomed that the UK Government’s negotiating mandate
appeared open to the possibility of negotiating a shared database for
registration data, 46 but said that a future trade agreement should go
“beyond existing cooperation agreements” between ECHA and non-
EEA countries. 47 See section 5.3 below for a discussion of data
challenges for a separate UK REACH regime. The Government states
that the transitional provisions included in the UK REACH regime
(Section 5.2) are intended address industry concerns regarding cost and
continuity of supply. 48
Concerns about lowering chemical safety standards
A UK version of REACH would come into force at the end of the
transition period that would retaining EU standards on chemicals at that
point (see Section 5 below). A separate UK chemicals regime as outlined
by the Government means that the UK would not be obliged to follow
EU decisions such as on authorisations or restrictions of chemicals going
forward. This has led to concerns about potential lowering of chemical
safety standards in the UK if the UK diverges from EU REACH. For
example, press reports and chemical safety campaigners have raised
concerns that a trade deal with the US could see chemicals that are
restricted in the EU allowed into the UK. 49
Campaign groups such as CHEMTrust and Greener UK have called for
the Government to accept alignment with EU chemical-related laws to
“ensure the best protection of our health and the environment”. 50 In a
letter to the Secretary of State for Environment, Food and Rural Affairs
in October 2020, a group of organisations including CHEM Trust,
Friends of the Earth and Breast Cancer UK stated that there was a “risk
of GB becoming a dumping ground for chemicals and products that do
not meet EU regulations, without a mechanism for matching EU
controls on chemicals”. 51

the UK remain aligned to the ECHA’s candidate list for substances of

very high concern and that “deviation should only happen where the
intention is to increase safety standards by moving more quickly to
restrict a substance of concern”. 52 Similar concerns have been raised by
MPs and Peers during debates in the House of Commons 53 and the
House of Lords. 54
The Government has repeatedly stated that any decisions taken on
chemicals as an independent UK regime “would be consistent with the
fundamental aims and principles of REACH” and would be based on
“rigorous assessment of the scientific evidence”. 55 In response to
questions in the House of Lords in March 2020, Defra Minister Lord
Goldsmith stated that the Government may consider divergence from
EU rules where it is in UK interests but that “does not mean reducing
standards”:
We will take decisions based on science and on the best available
evidence, including looking at approaches taken by other
chemicals regimes right across the world, well beyond the
European Union. We will not seek ongoing alignment with the EU
regulatory system but we will not diverge simply for the sake of it.
There may be good reasons for taking a different approach on a
particular substance to reflect UK circumstances, but that does
not mean reducing standards or levels of protection. [...]
The core principle is that it will be our choice. 56

Advantages of a separate UK system?

During a February 2020 Westminster Hall debate, Parliamentary Under-
Secretary of State for Defra Victoria Prentis stated that a UK REACH
regime would give the Government the “freedom to do things
differently where we consider that in our best interest”. 57
One criticism of REACH is that the process for making regulatory
decisions at the EU level is slow. 58 There are also concerns about the
level compliance in REACH registrations. 59 One potential advantage of a
UK REACH system could be for the UK to improve on the efficiency of
the EU system. 60 In oral questions in March 2020 Lord Goldsmith, Defra
Minister, referred to animal testing as one example of where UK could
diverge from the EU to improve the UK system:
For example, for many years the UK has been at the forefront in
opposing animal tests where alternative approaches can be
used—the last-resort principle. We could be more rigorous in

applying this principle in the future and there are many other
examples where we might want to diverge. 61
The Institute of Economic Affairs argued in September 2018 that
withdrawing from REACH would provide an opportunity to implement
“pro-competitive regulation”. 62 A European Commission report from
October 2016 considered the impact of REACH on international
competitiveness of the EU industry in comparison to regulations in
China, Japan, the USA, Canada, and South Korea. 63 It concluded that
“REACH does have a minor negative impact on the competitiveness of
the EU industry in relation to their third-country competitors” although
extent of this varies between different market situations and countries.
In terms of cost to place a new chemical on the market, the EU fell
within the middle of the range of countries considered, with costs being
higher than in the US but less than compared to Canada, Japan and
China.

4.4 Economic impact of Brexit scenarios on

the chemicals industry
The terms of any future UK-EU trade agreement will play a crucial role
in determining the impact of Brexit on the sectors of the UK economy
over the longer term.
At present, there is no official economic analysis from the Government
on the Withdrawal Agreement and its preferred trade relationship with
the EU (a free trade agreement similar to the one Canada has with the
EU). A Library Insight provides an overview of the evidence of the
potential economic impact of the Brexit deal negotiated by Boris
Johnson’s Government. This was originally written in October 2019 but
remains relevant in terms of the possible economic implications on the
economy as a whole.
However, Theresa May’s Government published an analysis of the long-
term economic impact of Brexit in November 2018. This used economic
models to compare how big the economy would be (measured by GDP)
in different future UK-EU trading scenarios relative to a ‘baseline’
scenario of the UK staying in the EU.
This analysis provides estimates of the long-term economic impact of
Brexit in terms of changes in economic output (as measured by GVA,
Gross Value Added) for the sectors of the economy. The chart on the
following page comes from this analysis. It presents estimates
depending on the future UK-EU trading scenario. Some of these
scenarios have been ruled out by the Government, but the following
scenarios are still relevant: 64

• Modelled no deal – in which the UK and the EU trade on World

Trade Organisation terms. This scenario is estimated to have an
impact on the whole economy in the long run of around -9%.
The impact on the chemicals, pharmaceuticals, rubber and
plastics industry is estimated to be roughly -22%.
• Modelled average FTA – a Free Trade Agreement (FTA) between
the UK and the EU. In this scenario, impact on the whole
economy is estimated to be around -5% in the long run. The
impact on the chemicals, pharmaceuticals, rubber and
plastics industry is estimated to be roughly -18%.
• Modelled EEA-type agreement – where the UK is a member of the
European Economic Area (EEA) inside the Single Market but not in
a customs union with the EU, which is similar to the relationship
Norway has with the EU (the Government has rejected this option
but it is presented here for context). In this scenario, the impact
on the whole economy is estimated to be around -1% in the long
term. The impact on the chemicals, pharmaceuticals, rubber
and plastics industry is also estimated to be roughly -1% in
the long term.
Note that these estimates are “trade only impacts”, and so do not
include other factors such as possible changes to levels of migration.

May Government’s EU Exit: Long-term economic analysis, published
November 2018.
21 Commons Library Briefing, 17 December 2020

5. UK REACH: Regulating
chemicals in the UK
The Government has been clear that it does not seek to participate in
the EU REACH framework. Therefore, subject to any cooperation
arrangements agreed, at the end of the transition period the UK will
become a third party to REACH. This means:
• A separate UK regime for regulating chemicals must be
established (called UK REACH) and
• UK companies’ EU-based registrations would become invalid and
UK companies must take action to continue to supply to EU
markets (see Section 6 below).

5.1 Legislation
At the end of the transition period (formally on ‘implementation period
completion day’) REACH would be retained in domestic legislation as
retained direct (principle) EU legislation in accordance with the EU
(Withdrawal) Act 2018 (as amended). 65 This means that the version of
REACH that is operative immediately before implementation period
completion day would be retained in UK law. This would include the
lists of restricted chemicals contained in the REACH Annexes and the
substances contained on the ECHA’s Candidate List for substances of
very high concern. 66
Secondary legislation was passed in March 2019 that would amend the
retained EU REACH Regulation in the UK to make it work in a UK-only
context: The REACH etc. (Amendment etc.) (EU Exit) Regulations 2019
(as amended).” 67 This Statutory Instrument (known as the ‘REACH EU
Exit SI’) would come into force on implementation period completion
day (currently 31 December 2020). It was made under section 8 of the
EU (Withdrawal) Act 2018, which provides the power to correct
“deficiencies” in legislation arising from withdrawal from the EU.
Together, the EU REACH Regulation (as retained EU law) as amended by
the REACH EU Exit SI will, for the purposes of this paper, be referred to
as the “UK REACH regime”.
Section 5.2 sets out the key features of the UK REACH regime;
commentary is provided in Section 5.3.

65
Section 3 of the EU (Withdrawal) Act 2018 (as amended). For further information
see Library briefing on the Constitutional implications of the Withdrawal Agreement
legislation (Section 8), 20 February 2020 and the Library Briefing on the new EU
Withdrawal Agreement Bill, 6 January 2020.
66
The Candidate List is not contained in the REACH regulation itself but maintained by
the ECHA. The REACH etc. (Amendment etc.) (EU Exit) Regulations 2019 (SI
2019/758) (as amended), Schedule 1 paragraph 46, inserts a requirement for the
HSE to include on its Candidate List all substances included on the ECHA’s candidate
list immediately before implementation period completion day.
67
The REACH etc. (Amendment etc.) (EU Exit) Regulations 2019 (SI 2019/758) (as

22 End of Brexit transition: chemicals regulation (REACH)

The Government has since laid two amending instruments to amend the
REACH EU Exit SI to correct technical gaps raised by industry:
• The REACH etc. (Amendment etc.) (EU Exit) (No. 2) Regulations
2019 (SI 858/2019, made on 11 April 2019) – this fixes a gap that
left some firms not covered by the transitional provisions. 68
• REACH etc. (Amendment etc.) (EU Exit) (No. 3) Regulations 2019
(SI 1144/2019, made on 2 July 2019) – this instrument concerned
a gap regarding authorisation applications that are pending a
decision by the European Commission. 69
The Explanatory Memoranda for each SI provide further details. 70
The Government also laid and approved the REACH etc. (Amendment
etc.) (EU Exit) Regulations 2020 in early December 2020 (see section 5.4
below for discussion)
Environment Bill 2019-21
The Environment Bill 2019-21 contains provisions that would give the
Secretary of State powers to amend the UK REACH regime by
regulations. There are certain listed protected provisions which would
not be amendable by regulations, such as Article 1 on the aim and
purpose of REACH and Article 5, the “no data no market” principle,
amongst others.
The Government states that this power is required to ensure a “smooth
transition” to a UK chemicals regime following the UK’s departure from
the EU, and to keep the legislation up to date in the future. 71 However,
the provisions have prompted concerns from environment groups and
some MPs about the potential for divergence between UK and EU
regimes (see Section 4.3 above). 72 For example, Greener UK called for
additional articles to be added to the protected list:
We are concerned about granting the Secretary of State such a
sweeping power to amend the main UK REACH text, as this could
be used to reduce the level of protection for the public and the
environment from hazardous chemicals. [...]
We will be examining the individual REACH articles in depth to
establish which ones should be added to the protected list. As a
minimum, we believe that Article 33 on information in the supply
chain and a right to know for consumers should be added to the
protected list. 73
The Bill has completed its Committee stages in the House of Commons
and is awaiting a date for the Report Stage.

covers the REACH provisions.

5.2 UK REACH: key features

The Government states that the UK REACH regulation aims to replicate
EU REACH “as closely as possible”. It would create a UK-wide market
for chemicals that would apply to all chemicals manufactured in or
imported into the UK. It is based on the “no data no market” principle:
all substances manufactured or imported into the UK must be registered
to be placed on the market.
The Government’s Explanatory Memorandum provides further detailed
information on the REACH EU Exit SI.
HSE as the UK Chemicals Agency
The Health and Safety Executive (HSE) would be established the
Chemicals Agency in the UK, taking over the functions of the ECHA
with input from the Environment Agency (EA) and devolved
environment regulators on environmental matters.
The functions of the European Commission (such as decisions on
restrictions and authorisations) would transfer to the Secretary of State.
The HSE has published guidance (Registration, Evaluation, Authorisation
and restriction of Chemicals (REACH) regulation at the end of the
transition period) which sets out what businesses need to do ahead of
the end of transition period.
In addition, the Department for Environment, Food & Rural Affairs has
published guidance on How to comply with REACH chemical
regulations, last updated 27 October 2020.
Devolved Administrations
The UK REACH regime was initially intended to apply UK-wide (see
section 5.4 for recent changes to its geographical application to Great
Britain only).
The Secretary of State would make decisions with the consent of the
devolved Administrations in areas of devolved competency (e.g.
environmental protection), with the devolved Administrations permitted
to take urgent temporary restriction action in some cases, which would
then be followed up through a UK-wide procedure. 74 The Scottish and
Welsh Governments were content for devolved matters to go in the UK-
wide SI. 75 76

24 End of Brexit transition: chemicals regulation (REACH)

As explained in section 3.2 above, under the Northern Ireland Protocol

in the Withdrawal Agreement, the EU REACH Regulation (which
currently applies across the UK until the end of the transition period)
would continue to apply in Northern Ireland after the end of the
transition period if the UK and EU do not reach a future relationship
agreement. A separate, domestic UK REACH system would apply across
Great Britain after the transition period.
UK chemicals database and IT system
Establishing a UK chemicals regime requires setting up a UK database of
registered substances, in effect replicating the ECHA system.
Defra’s internal Digital Data and Technology Services directorate has
been developing the UK REACH IT system. 77 The Government has stated
that the UK system will operate “very much like” the ECHA system,
with the “same software requirements” and processes. 78 The
Government stated in October 2019 that the cost of establishing the UK
REACH IT system had been £14.32 million up to that point. 79
UK REACH registrations
Existing EU REACH registrations and authorisations held by UK
companies would be automatically transferred (“grandfathered”) from
the EU to UK system without a fee. 80
UK companies would need to notify and submit registration data to the
HSE within a period of transition that would begin after the regime
comes into force (Box 2). 81 The transitional provisions for data
submission have been the focus of concern from industry stakeholders
(see Section 5.3 below).

Box 2: Transitional provisions for data submission

The legislation establishes a two-stage process for which companies must provide information to the
HSE to support “grandfathered” EU registrations:
• Within 120 days, UK companies with EU registrations would have to notify the HSE and provide
basic data such as company name, company details, substances registered, quantities produced
and evidence of their existing ECHA registration.
• Within two years, companies would need to submit full information to support the registration,
such as information and data on the properties of the substance and its safety. The data
requirements are the same as for EU REACH.
Companies importing chemicals to the UK from the EEA would have new registration obligations under
the UK REACH regime that they did not have under EU REACH. This is because while the UK was in the
EEA these companies were moving chemicals within the single market and therefore did not have
registration obligations under EU REACH.

80
Explanatory Memorandum, Para 13.1.
81
The legislation currently reads that the transition periods begin on “exit day”
(defined as 31 January 2020). It is expected that data submission dates in the REACH
EU Exit SI will be updated in due course to be refer to “IP completion day” rather
than “exit day”. See: Burges and Salmon, The road to UK REACH - what happens
next?, Simon Tilling, 17 February 2020.
25 Commons Library Briefing, 17 December 2020

A different notification timeframe is therefore provided for companies importing substances from the
EEA. The deadlines for submitting information to the UK Chemicals Agency under this scenario,
however, were recently amended by the REACH etc. (Amendment etc.) (EU Exit) Regulations 2020:
• within 300 (rather than the original 180) days, companies would be required to notify the HSE of
the substances they import from the EEA, including basic information about the substance and
its safe use;
• a full information package to support the registration would be required and has been extended
to run in a “phased manner by 2, 4 and 6 years. This would mean a total of 2, 4 and 6 years +
300 days to supply the full information. The phasing will operate by reference to tonnage bands
and hazard profile, with the highest tonnages and most significant hazards coming first”. 82
Under the previous deadlines, all registrants (irrespective of tonnage band) were required to
submit full information within two years. The staggered registration period will start from 28
October 2021.

Scientific advice and input

The UK REACH regime would place a duty on the HSE to commission
external scientific advice when developing its opinions on regulatory
measures, except in circumstances where there are “justifiable reasons”
not to. The Explanatory Memorandum to the REACH EU Exit SI explains
that one justifiable reason may be where the ECHA has already
published a robust opinion on a substance. 83 The HSE is required to
consult on and publish a statement on how it will exercise its duty to
commission scientific advice within three months (of the regime coming
into force). 84
Appeals against HSE decisions
The UK REACH regime would have a different mechanism for appeals
against HSE regulatory decisions compared to the EU regime. Appeals
against HSE decisions would be heard by the First-Tier Tribunal (which
already hears appeals against government regulatory bodies on
environment enforcement matters, such as appeals against Environment
Agency fines). Under the EU REACH regime there is a specific body for
hearing appeals against ECHA decisions (called the ECHA Board of
Appeals).
An article from law firm Burges and Salmon summarises the similarities
and differences between the two bodies. For example, that the First-Tier
Tribunal hearings are adversarial in nature whereas the ECHA Board of
Appeal takes more the form of an independent review. The article also
notes the potential for divergence in decision making between the UK
and EU systems if there are two different adjudicating bodies. 85

5.3 Commentary on the UK REACH regime

Parliamentary debate on the REACH EU Exit SI 2019
The REACH EU Exit SI was subject to the affirmative procedure and
approved by the House of Commons in February 2019, 86 and the House
of Lords on 26 March 2019. 87 There was strong opposition raised in the
debates in both Chambers. In the House of Lords, the following motion
of regret was passed which articulated and placed on the record the
main concerns (further commentary on each point is provided in the
following sections):
At the end insert
“but this House regrets that the draft Regulations fail to fulfil the
Prime Minister’s intention to maintain the United Kingdom’s
participation in the European Chemicals Agency, which would
have avoided
(1) the duplication of registrations and the consequential
increased costs to United Kingdom manufacturers, downstream
users and importers,
(2) the duplication of testing procedures, including animal testing,
and
(3) the pressure on the resources and expertise of the Health and
Safety Executive and the environment agencies, which could
increase the risks to United Kingdom citizens’ health, and to our
environment;
and calls on Her Majesty’s Government to make continued United
Kingdom participation in the European Chemicals Agency and
REACH an objective in negotiations with the European Union”. 88

Data submission deadlines

Industry stakeholders are concerned about the need to submit full
registration data to the HSE under the UK REACH regime and the
timeframes for doing so. The data sharing arrangements facilitated
through REACH (see Box 1) means that companies may not have access
to all the scientific data and test results that support their REACH
registrations. A survey conducted by the Chemical Business Association
in February 2019 found that three-quarters of the 38 companies
surveyed (holding 351 registrations) did not own all the data studies for
their EU registrations. 89
Industry stakeholders argue that getting access to full supporting data
necessary to support UK REACH registrations (which has the same data
requirements as the EU system) would create significant costs. Potential
costs cited include fees for new commercial data sharing agreements,

cannot be shared. Industry argues these costs would impact the

substances being registered in the UK system while bringing “no

commercial or environmental benefit”. 90 The German chemicals firm
BASF is quoted in The Economist as estimating that registration with UK
REACH will cost the company £70m. 91 Without an information sharing
deal, BASF has warned that some chemicals may “disappear” from the
UK market, as they did when EU REACH was introduced:
Many substances previously available in the EU were not
registered under Reach and thus removed from the EU market.
Without some form of information-sharing deal, we have no
reason to believe that the situation in the UK will be different. 92
In addition, industry argues that the 2-year time period originally set out
in the UK REACH regime to provide data is not feasible in practice if
further testing is required. 93
During a Westminster Hall debate in February 2020, Parliamentary
Under-Secretary of State for Defra, Victoria Prentis, explained that full
data was required by the HSE to enable it to properly understand the
risks of chemicals and operate an effective regulatory regime:
In short, we need it because we will not be able to rely on the fact
that the data has already been sent to the ECHA. Registration is
how a company shows its understanding of the hazards and risks
of a chemical. It does not mean that the ECHA has, in legal terms,
approved a chemical or endorsed it as safe. The data is necessary
for any regulator, such as the Health and Safety Executive, to
operate an effective regulatory regime, to understand the hazards
and risks of chemicals, and to ensure their safe use. 94
Government has said it would “keep under review” the timeframes for
the submission of the full technical information. 95 The Delegated Powers
Memorandum published by the Government alongside the Environment
Bill 2019–20 (see section 5.1 above) indicated that the Government
“anticipated” that the data submission deadlines may need to be
amended and that the powers contained in the Bill would allow this. 96
On the 2 September 2020, the Parliamentary Under Secretary of State
at Defra, Rebecca Pow, wrote to the Chair of the Environmental Audit
Committee. She explained that the government planned to make
changes to the deadlines for businesses to provide the data to support
their registrations under UK REACH:

28 End of Brexit transition: chemicals regulation (REACH)

The principle of “no data, no market” is central to UK and EU

REACH. The provision of data to the regulator gives public
assurance that industry understands the risks of the chemicals
they use and gives the UK regulators a full evidence base to
inform future regulatory decisions. Therefore, in considering the
findings from the evidence gathering exercise we looked at
options which would enable industry to mitigate costs without
reducing important environmental and health protections.
We have concluded that the most effective way of achieving this
is to extend the transitional data submission timetable in a
phased, risk-based, manner. This also reflects suggestions made
by industry. 97
The proposed changes were set out in REACH etc. (Amendment etc.)
(EU Exit) Regulations 2020 (see section 5.4 below) and highlighted in
Box 1 above.
Concerns about animal testing
One of the key aims of REACH is to minimise animal testing by requiring
that animal testing can only be used as a “last resort” (that is, if there is
no other way of testing the safety of a substance). Data sharing
obligations under REACH (see Box 1) helps ensure that tests on animals
are not duplicated.
There have been concerns raised by environmental and animal welfare
groups that a separate UK REACH system could result in animal tests
being duplicated if UK and EU companies are not able to easily share
existing data on test results between the regulatory systems. 98 Industry
stakeholders have also raised this concern. 99
In the Westminster Hall debate in February 2020, Defra Parliamentary
Under-Secretary of State Victoria Prentis said that the UK will “continue
to be at the forefront of opposing animal tests where alternative
approaches can be used”. 100 During oral questions in the House of
Lords, Defra Minister Lord Goldsmith suggested that a “more rigorous
approach” to animal welfare could be one area where the UK could
improve on the EU system (see Section 4.3 above). 101
Scientific advice and oversight
The Environmental Audit Committee (EAC), House of Lords EU Energy
and Environment Sub-Committee along with environmental campaign
groups, such as CHEM Trust, have raised concerns that the scientific
oversight committees and stakeholder engagement mechanisms that
inform decisions under the EU REACH regime (see Section 1.2 above)

are not replicated in the UK regime, arguing that this could result in less
transparent decision making. 102
A group of organisations, including CHEM Trust, Friends of the Earth
and Breast Cancer UK, wrote jointly to the Secretary of State for
Environment, Food and Rural Affairs in October 2020, expressing
concern that the scrutiny mechanisms in UK REACH were “inadequate”:
There are currently inadequate mechanisms for oversight and
scrutiny and for stakeholder engagement and public participation.
This would result in a more closed and less transparent system
than ECHA’s, that would be more susceptible to industry
lobbying. By comparison, the committee structure within ECHA
helps to ensure its work can be challenged and the best
information is available for these discussions, helping to avoid
mistakes and to ensure that decisions are made more
independently and transparently. 103
In its July 2019 report on Toxic Chemicals in Everyday Life, EAC
recommended that the HSE, in its statement on how it will comply with
the duty to commission external scientific advice, should “outline a
formal role in the substance evaluation process for the Committee on
Toxicity and Hazardous Substances Advisory Committee. It should also
establish a forum for engagement with stakeholders.” 104 In response to
the Committee, the Government stated that existing stakeholder
mechanisms, such as the UK Chemicals Stakeholder Forum would
continue under the new regime. 105
HSE and Environment Agency resources
There have been concerns raised about whether the HSE and the
Environment Agency (EA) would have the financial and staffing
resources to manage the additional regulatory responsibilities of the UK
REACH regime. 106 For example in the February 2020 Westminster Hall
debate, Shadow International Trade spokesperson Bill Esterson raised
the question of the extent to which the HSE would replicate the ECHA’s
workload:
Concerns have also been raised about the capacity of the HSE and
the legal framework it will follow. It could either repeat the work
of ECHA or rely on the work ECHA has carried out. The former
would be hugely expensive, time consuming and dependent on a
level of scientific expertise that may not be available. The latter
could leave it open to challenge on the grounds that it should not

be reliant on EU evidence and should have made its own

assessment of risk. Either approach is potentially problematic. 107
In the House of Commons debate on the REACH EU Exit SI in February
2019, Mary Creagh, then Chair of EAC, raised concerns about the HSE’s
budget, compared to the ECHA’s:
The working budget for the European Chemicals Agency is €100
million a year, compared to the roughly £2.2 million the HSE
currently spends regulating chemicals. Given the recent budget
cuts to the HSE, it is worth noting that it took the EU five years to
fully staff the European Chemicals Agency. 108
In that debate, then Defra Minister Dr Thérèse Coffey stated that it
expected the future cost of running UK REACH to be £13 million per
year and that the EA would be recruiting an extra 10 staff and the HSE
would be taking on 35-40 additional staff. She stated that the HSE
would be building on existing expertise and highlighted that the ECHA
covers a much larger market (28 Member States). 109 However, as law
firm Burges and Salmon point out, the ECHA despite being a large
organisation with significant technical expertise “does not do everything
itself”, it draws on the resources of the Member States for “complex
work” such as substance evaluation. 110
Defra subsequently told the Lords Secondary Legislation Scrutiny
Committee in November 2020 that the HSE was recruiting 130 extra
staff “to cover the transition to the domestic system”. 111 Defra added
that it “aims to have 100 recruits in post by January and 130 by the end
of the financial year — these will be split over all the chemical regimes
but around 40 of these staff will be specifically for REACH”. 112
In response to the Committee’s concerns that “the HSE will not have all
the staff in post that it will need to exercise its regulatory functions
under the new regime from 1 January 2021” 113, the Defra Minister,
Lord Goldsmith, stated that it was “not necessary to have a fully staffed
organisation on day one”:
Instead, the approach to recruitment gives time to train and build
up the functions and services of UK REACH before key deadlines
on registration and evaluation kick in”. 114

31 Commons Library Briefing, 17 December 2020

House of Commons on the 8 and 9 December 2020 respectively. The

draft Explanatory Memorandum to the Regulations explains that the
instrument introduces several changes. First, it redefines the
geographical application of the new domestic REACH regime so that it
now only applies to Great Britain (England, Scotland and Wales) rather
than to the whole of the UK as originally intended.
This change is to ensure the UK meets its obligations under the
Northern Ireland Protocol. The 2020 Regulation therefore amends both
the REACH etc. (Amendment etc.) (EU Exit) Regulations 2019 (S.I.
2019/758) and the REACH Enforcement Regulations 2008 (S.I.
2008/2852) so that the EU REACH regime can continue to apply to
Northern Ireland after the end of the transition period. After the end of
the transition period, Northern Ireland and Great Britain will be subject
to different REACH regimes.
Second, the Regulation address the barriers to trade between Northern
Ireland and Great Britain arising from two separate REACH regimes so
as to ensure that “Northern Ireland goods [can] enter the GB market
with minimal regulatory disruption”. The Defra Minister, Lord
Goldsmith, explained the change as follows:
The instrument permanently removes the requirement for a full
REACH registration for chemicals that are, or are in, qualifying
Northern Ireland goods being placed on the GB market. It replaces
that with a light-touch notification process, which will ensure that
the HSE will know what chemicals are being placed on the GB
market. Information necessary to ensure safe use will also still be
passed down the supply chain within Great Britain. Substances of
very high concern entering Great Britain from Northern Ireland
will still need a UK REACH authorisation. 115
Third, it extends the existing deadlines for the submission of registration
data to the domestic REACH system by existing registrants and
downstream users. Under the 2020 Regulations, the initial notification
stage for existing downstream users (that will become importers of
chemicals from the EU/European Economic Area (EEA) or Northern
Ireland after the end of the transition period) is extended from 180 to
300 days, starting from 1 January 2021. The deadline for submitting full
registration information is replaced by phased approach that spreads
the duty over two, four and six years – depending on the tonnage and
hazardous nature of the chemical – starting from the end of the 300-
day period. According to Lord Goldsmith, the change represents a:
risk-based approach by requiring the submission of data on the
highest tonnages and most hazardous chemicals first. The aim is
to give companies more time and capability to comply with the
legislation by reducing and spreading costs, and giving them more
time to negotiate mutually beneficial data-sharing arrangements
with other companies in the UK and the EU. 116
A non-fatal motion to the instrument was tabled by Baroness Hayman
(Labour) stating:

115
HL Deb, 8 December 2020 c1156
116
HL Deb, 8 December 2020 c1156
32 End of Brexit transition: chemicals regulation (REACH)

this House regrets that the Regulations (1) fail to provide an

analysis of the costs of the new domestic Registration, Evaluation,
Authorisation and Restriction of Chemicals (REACH) regime, (2)
introduce additional costs and administrative burdens for United
Kingdom businesses, and (3) create unacceptable risks around the
availability of chemicals safety data; notes concerns about the
ability of the Health and Safety Executive to fulfil its additional
responsibilities when the domestic REACH regime becomes
operable on 1 January 2021; and further regrets that Her
Majesty’s Government have not addressed concerns raised by
Parliament when proposals for a domestic REACH regime were
debated in 2019.
Concerns about additional costs incurred, access to chemicals safety
data, and HSE’s staffing and resources were reiterated by other Peers
during the debate. Baroness Hayman withdrew the motion, stating that
while the Minister had “not answered the many concerns raised” there
would be “opportunities to consider the matter further during debate
on the Environment Bill”. 117

5.5 UK Chemicals Strategy

The Government’s 25 Year Environment Plan (11 January 2018)
promised a Chemicals Strategy that would set out the Government’s
approach as it leaves EU to managing chemicals with potential to cause
harm. 118
The Environmental Audit Committee’s July 2019 report on Toxic
Chemicals in Everyday Life recommended that the Strategy should “lay
out a plan for remediation of harmful regulated substances in the
environment with binding targets and a ring-fenced budget”. The
Committee stated the Strategy should “take full account of the human
health impacts of chemical”, highlighting the role that public health
bodies should play. 119
The Government’s response to the Committee provided the following
description of what the Strategy would contain:
15. The Strategy will be a vehicle for exploring options to develop
an early warning system for identifying emerging chemical issues,
considering how to address the tracking of chemicals in products,
and working internationally on the standardisation of methods
that assess chemical safety. It will be developed to ensure a
holistic approach to the safe management of chemicals, building
on existing government strategies, such as the Resources and
Waste and Clean Air Strategies, both of which have been
successfully delivered in line with 25YEP commitments.
16. We expect a Chemicals Strategy to play a key part in enabling
the transition towards a circular economy approach, building on
existing commitments in our Resources and Waste Strategy

18. The Chemicals Strategy will set out our approach to the safe
and sound management of chemicals. It will take account of the
Chief Medical Officer’s recommendations to consider the impact
of chemicals and chemical mixtures on human health. It will
incorporate the Government’s priorities for our domestic
regulation and reflect our future relationship with the EU. We are
committed to maintaining the UK’s existing high standards in the
safe and effective regulation of chemicals after we leave the EU.
19. The Strategy will also address concerns related to endocrine
disruptors (EDCs) and the use of potentially toxic substances in
furniture and household goods.
In February 2020 the Government stated that it was engaging with a
range of stakeholders and that a Call for Evidence would be published
in the spring. 120 Parliamentary Under-Secretary of State for Defra
Victoria Prentis stated in February 2020 that the Strategy would “aim to
drive sustainability, circularity and innovation in the chemicals industry,
while protecting human health and the environment from harmful
chemical exposure”. 121
Specialist Environmental news journal ENDS Report reported in April
2020 that Defra’s the work on the chemicals strategy had been delayed
due to the coronavirus outbreak. 122 In response to a Parliamentary
Question on the development of the Chemicals Strategy, the Defra
Minister, Rebecca Pow, explained that work on the Strategy was
underway:
It will build on a robust statutory regime and our international
obligations and set out direction of travel on important policies.
The next key milestone is the Call for Evidence in 2021. It will help
inform the development of a draft Strategy for consultation. 123
EU Chemicals Strategy for Sustainability
On 14 October 2020, the European Commission adopted the EU
Chemicals Strategy for Sustainability. 124 It proposes actions to:
• account for the cocktail effect of chemicals when assessing
risks from chemicals
• phase out the use of per- and polyfluoroalkyl substances
(PFAS) in the EU, unless their use is essential
• boost the investment and innovative capacity for
production and use of chemicals that are safe and
sustainable by design, and throughout their life cycle
• promote the EU’s resilience of supply and sustainability of
critical chemicals

EU
Industry in the UK has raised concerns that the implementation of the
Strategy may lead to greater divergence between UK REACH and EU
REACH. According to the European Chemical Industry Council, if
fundamental changes to the EU REACH system are made in parallel with
the establishment of UK REACH, “we also introduce a wider gap with
our neighbours”. 125

35 Commons Library Briefing, 17 December 2020

6. UK access to EU market
At the end of the transition period, UK companies wishing to export
chemicals to the EEA single market would still need to comply with EU
REACH (and any other relevant regulations) and, in the absence of a
preferential trade agreement, pay a tariff.
Only companies based in the EEA may register directly with the ECHA.
This means that after the end of the transition period, UK-companies’
EU REACH registrations would become invalid. To preserve EEA market
access, UK companies would need to transfer their registrations to an
EEA-based entity before the end of the transition period. This may be an
affiliate/subsidiary company or an “only representative” agent (see
section 1.3 of this paper).
The ECHA has explained that setting up a company “on paper” is not
enough to satisfy REACH registration requirements:
A registrant is responsible for the substances covered by their
registrations. This means that the responsible staff and relevant
documentation must be present at the address of the registrant –
setting up a company on paper only in the EU-27 or EEA is not
sufficient. 126
Alternatively, without a valid REACH registration, the obligation for
compliance with REACH would fall to the importer of the substance (i.e.
UK chemical companies’ EEA-based customers).
The European Commission reported that as of mid-August 2019, 52%
of UK REACH registrants had transferred their registrations to an EU27
entity. 127 The Chemical Business Association highlighted in April 2018
that a significant number of their member companies were planning to,
or had already, created subsidiaries in other EU member states to ensure
access to the EU market. 128
The ECHA’s webpage on the UK’s Withdrawal from the EU provides
advice for UK and EU companies and is updated on a regular basis.
UK Government guidance for industry can be found on gov.uk (How to
comply with REACH chemical regulations) and on the Health and Safety
Executive’s Brexit webpages (Registration, Evaluation, Authorisation and
restriction of Chemicals (REACH) regulation at the end of the transition
period).
