Dangerous Goods Transportation Regulations for Lithium Cells and Batteries
Some transportation regulations have been recently revised and will come into effect after Jan. 1, 2015. The summary is shown in the
following table. Please use updated Dangerous Goods Regulations listed in Normative Reference to confirm details.
■ The major revisions for air transport of lithium cells and batteries
(1) Lithium metal cells and batteries transported as cargo will be restricted to cargo aircraft only.
Note. The prohibition does not apply to lithium metal batteries packed with equipment (PI 969) or contained in equipment (PI 970).
(2) Gross mass will change to net quantity for both lithium ion cells and batteries (PI 965 Section IB) and lithium metal cells and batteries
(PI 968 Section IB)
Lithium Metal Cell: ≤ 0.3 g Cell: ≤ 1.0 g Cell: ≤ 1.0 g Cell: > 1.0 g
Content Battery: ≤ 0.3 g Battery: ≤ 2.0 g Battery: ≤ 2.0 g Battery: > 2.0 g

■ The major revisions for UN Model Regulations 18th Revised Edition
(1) Damaged or defective cells or batteries shall be transported as "Class 9" hazardous goods according to Special Provision 376 and
Packing Instruction P908 or LP904.
(2) Cells and batteries transported for disposal or recycling shall be transported as "Class 9" hazardous goods according to Special
Provision 377 and Packing Instruction P909.
The IMDG Code 2014 edition will contain the descriptions of these UN recommendations. The voluntary compliance date is Jan. 1,
2015. Compliance becomes mandatory on Jan. 1, 2016.
Although these revisions will be reflected in each country's regulations, some districts, countries or airlines may establish their own
special requirements. Therefore the shipper shall confirm with the forwarder in advance.
Reference
Except for air transportation, the necessary requirements to transport lithium metal batteries or lithium-ion batteries as exempted from
regulation (non-restricted goods) are as follows;
1. The minimum requirements to transport lithium metal batteries as non-restricted goods are as follows;
a) Cells and batteries shall be manufactured under a quality management program.
b) For a lithium metal or a lithium alloy cell, the lithium content must not be more than 1 g.
For a lithium metal or lithium alloy battery, the aggregate lithium content must not be more than 2 g.
c) E
ach cell or battery must be of the type proven to meet the requirements of each test in the UN Manual of Tests and Criteria, 5th
revised edition, Part III, sub-section 38.3.
d) A battery handling label must be displayed on each package. A telephone number must be printed on the label for additional
information.
e) Each consignment must be accompanied by a document for transport with an indication that:
• the package contains lithium metal cells or batteries;
• the package must be handled with care and that a flammability hazard exists if the package is damaged;
• special procedures should be followed in the event that the package is damaged, to include inspection and repackaging if
necessary; and
• a telephone number for additional information.
f) Each package must be capable of withstanding a 1.2 m drop test.
g) Except when batteries are installed in or packed with equipment, packages shall not exceed 30 kg gross mass.
2. The minimum requirements to transport the lithium-ion batteries as non-restricted goods are as follows;
a) Cells and batteries shall be manufactured under a quality management program.
b) For lithium-ion cells, the Watt-hour rating is not more than 20 Wh. For lithium-ion batteries, the Watt-hour rating is not more than
100 Wh. The Watt-hour rating must be marked on the outside of the battery case except for those manufactured before Jan. 1,
2009.
c) E
ach cell or battery is of the type proven to meet the requirement of each test in the UN Manual of Tests and Criteria, 5th revised
edition, Part III, sub-section 38.3.
d) A battery handling label must be displayed on each package. A telephone number must be printed on the label for additional
information.
e) Each consignment must be accompanied by a document for transport with an indication that:
• the package contains lithium-ion cells or batteries;
• the package must be handled with care and that a flammability hazard exists if the package is damaged;
• special procedures should be followed in the event the package is damaged, to include inspection and repackaging if necessary;
and
• a telephone number for additional information.
f) Each package must be capable of withstanding a 1.2 m drop test.
g) Except when batteries are installed in or packed with equipment, packages shall not exceed 30 kg gross mass.
Maxell will provide certificates for b) and c) as the need arises. Documentation for d) and e) needs to be prepared by the customer.
If our package is used for transport, Maxell will provide the certificate for f) as the need arises. However, if the customer’s package
is used, the customer must confirm the package can withstand a 1.2 m drop test. Furthermore, even if our package is used for
transport, the telephone number printed on the label must be changed to that of the sender (customer).
