Dear Capt. Bugg:
This responds to your electronic mail requesting clarification under the Hazardous
Materials Regulations (HMR; 49 CFR Parts 171-180) of the marking requirements for
certain bulk packagings. Specifically, you ask whether a bulk packaging that is dual
marked as a DOT specification intermediate bulk container (IBC) and a DOT
specification portable tank is required to be marked with the identification number as
required in § 172.331 for IBCs, or the proper shipping name, the name of the owner or
lessee, and the identification number as required in § 172.326 for portable tanks.
An IBC must be marked with the identification number in accordance with § 172.331 and
a portable tank must be marked with the proper shipping name, the name of the owner or
lessee, and the identification number in accordance with § 172.326. Therefore, to satisfy
the marking requirements, the dual-marked bulk packaging must be marked with the
proper shipping name, the name of the owner or lessee, and the identification number as
specified in § 172.326. Also, the bulk packaging must conform to all applicable
specification requirerents and be authorized for the hazardous material being
transported.
I hope this information is helpful. If you have additional questions, please do not hesitate
to contact us.
Sincerely,
Hathe z Michell
