Dear Mr. Kerchner:
This is in response to your June 3,2008 electronic mail requesting clarification of the
packaging requirements in the Hazardous Materials Regulations (HMR; 49 CFR Parts 17 1 -
180) and the various international dangerous goods regulations pertaining to lithium batteries.
Specifically, you ask if a shipper may use strong outer packagings, protective enclosures or
pallets instead of UN combination packages provided certain requirements are met.
As provided by 5 173.185(g) and Packing Instruction 903 of the International Civil Aviation
Organization Technical Instructions and the International Maritime Dangerous Goods Code,
batteries employing a strong, impact-resistant outer casing and exceeding a gross weight of 12
kg (26.5 lbs.), and assemblies of such batteries, may be packed in strong outer packagings, in
protective enclosures (for example, in fully enclosed wooden slatted crates) or on pallets.
Batteries must be secured to prevent inadvertent movement, and the terminals may not
support the weight of other superimposed elements. Batteries packaged in this manner are
not subject to specification packaging requirements but are subject to the other requirements
of 173.185(a) or Packing Instruction 903 including shoi-t circuit protection and design type
testing.
Batteries packaged in the manner described above may be transported by highway, rail, and
vessel. Such batteries are not permitted for transportation by passenger aircraft, and may be
transported by cargo aircraft only if approved by the Associate Administrator prior to
transportation.
I hope this information is helpful. Please contact us if you require additional assistance.
Sincerely,
Susan Gorsky

Re: Request for Interpretation on ICAO TI PI 903 and 49 CFR 173.18Xa)
Dear Ms. Drakeford:
As a follow-up to my June 3 email to your office, I am writing for a clarification on the provision found
in the lithium battery regulations at 49 CFR 173.1 85(g). A similar provision is in Packing Instruction 903 of the
IMDG Code and Packing Instruction 903 of the ICAO Technical Instructions.
49 CFR 173.185(g) and Packing Instruction 903 state that "Batteries employing a strong, impact-
resistant outer casing and exceeding a gross weight of 12 kg (26.5 lbs.), and assemblies of such batteries, may
be packed in strong outer packagings, in protective enclosures Cfor example, in fully enclosed wooden slatted
crates) or on pallets. Batteries must be secured to prevent inadvertent movement, and the terminals may not
support the weight of other superimposed elements. Batteries packaged in this manner are not permitted for
transportation by passenger aircraft, and may be transported by cargo aircraft only if approved by the
Associate Administrator prior to transportation." Large lithium batteries normally must be shipped in Packing
Group I1 packaging. However, this provision at 49 CFR 173.185(g) and in Packing Instruction 903 appear to
authorize shippers to use strong outer packagings, or protective enclosures (for example, in fully enclosed
wooden slatted crates,) or pallets instead of Packing Group I1 packaging if the battery exceeds 12 kg and has an
impact-resistant outer casing. 1 recognize that the battery also is subject to the UN testing requirements.
Therefore, my question is -
May a shipper use strong outer packagings, or protective enclosures (for example, in fully enclosed
wooden slatted crates,) or pallets instead of Packing Group I1 packaging to ship a lithium battery if it exceeds 12
kg, has an impact-resistant outer casing, and has passed the required LIN lithium battery tests?
I can be reached at 202.719.4.109 if you have any questions. Thank you for your assistance.
Sincerely,
