Dear Mr. Spease:
This letter is in response to your June 21, 2019, email requesting clarification of the Hazardous
Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to lithium batteries. You
describe a lithium ion battery that weighs approximately 50 kg, with a completely enclosed
casing with 1.5 mm thick steel walls. Five sides of the casing are welded together, and the sixth
side is mechanically fastened. You state that the battery terminals will have insulators installed to
protect from short circuit during transportation. You also note that the batteries will be oriented
so that the terminals do not support the weight of other superimposed elements when packaged,
and that spacers and strapping will be used to secure the batteries to a pallet/box to prevent
shifting during transportation.
We have paraphrased and answered your questions as follows:
Q 1. You ask for confirmation that the battery packaging described above, and illustrated in
the photograph you provided, would meet the requirement in § 173 .185(b )( 5) to have a
"strong, impact-resistant outer casing."
A 1. The answer is yes. Based on the pictures and information you provided, the battery
assembly appears to be fully enclosed in its metal casing. This appears to rrieet the
requirements of a strong, impact-resistant outer casing as specified in § 173. l 85(b )( 5).
Q2. You ask for confirmation that the packaging would not need UN specification packaging
and that securing batteries to a pallet, or in a crate/box, would meet§ 173.185(b)(5) for
transportation by highway or vessel.
A2. You are correct. When all other requirements of§ 173.185(b) are met in addition to using
a strong and impact resistant outer casing, UN specification packaging is not required.
Q3. You ask for confirmation that the answer provided in a letter of interpretation (LOI)
Reference No. 05-0017 applies to your scenario, and that a highway or vessel shipment of
the lithium batteries you described would not constitute a bulk packaging even if the total
weight of the pallet exceeds 400 kg.

A3. The answer regarding palletized batteries in LOI Reference No. 05-0017 is specific to the
packaging provisions for wet batteries in § 173 .15 9. However, lithium batteries secured
to a pallet in accordance with § 173. l 85(b )( 5) would also be considered a single non-bulk
package. The palletized batteries should be marked and labeled as a non-bulk package
even if the completed package weighs more than 400 kg (882 pounds).
I hope this information is helpful. Please contact us if we can be of further assistance.

Subject: LETTER OF INTERPRETATION REQUEST-LITHIUM ION BATTERY PACKAGING
Dear Sir or Madam,
I am requesting a letter of interpretation on packaging of a lithium ion battery.
We have a lithium ion battery design where the battery has a mass of approximately 50kg, a casing that is approximately
450mm x 400mm x 110mm with 1.5mm thick steel walls. Five sides of the casing are welded together with the sixth side
mechanically fastened.
The battery terminals will have insulators installed to protect from short circuit during transportation. The batteries will
be oriented so that the terminals do not support the weight of other superimposed elements when packaged.
Spacers and strapping will be used to secure the batteries to a pallet/box to prevent movement during transportation
and to the protect guide pin and electronic module which are located on the outside of the casing.
Can you confirm that the battery would meet 49CFR173.185(b)(5) as having a "strong, impact-resistant outer casing"?
Can you confirm that the packaging would not need to use UN specification packaging and that securing batteries to a
pallet, or in a crate/box would meet 49CFR173.18S(b)(5) for transportation by ground or vessel?
Can you confirm that for ground and vessel shipments of these 50kg batteries they would not constitute a bulk shipment
when the total weight of the pallet/box would weigh in excess of 400kg (ie more than eight, 50kg batteries per
pallet/box) when packaged in accordance with 49CFR173.185(b)(5) (reference PMHSA Interpretation 05-0017)?
