Dear Mr. Bartley:

This is in response to your July 22, 2010, letter requesting clarification on marking requirements for bulk packagings under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if the technical name is required as part of the marking on portable tanks in accordance with § 172.326.

As provided by § 172.326(a), a portable tank containing a hazardous material must be marked with the proper shipping name for the material as specified in the § 172.101 table on two opposing sides. While marking a technical name in association with the proper shipping name to identify the contents of the material in a portable tank would provide useful information for emergency response purposes, it is not required.

I hope this information is helpful. If you have further questions, please contact this office.
