Dear Mr. Ziebell:

This responds to your e-mail regarding identification number (ID) displays on portable tanks under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). In your follow-up e-mail, you stated that the regulations do not appear to address transport vehicle or container marking requirements when they contain bulk packagings marked in accordance with § 172.336(d). Specifically, you ask for clarification of the marking requirements for a portable tank that is labeled and marked in accordance with § 172.514(c) and § 172.336(d).

The exceptions in § 172.336(d) and § 172.514(c) provide no relief from marking the transport vehicle. The transport vehicle must be marked in accordance with § 172.326(c) if the ID number markings required by § 172.302(a) are not visible. If you choose to use the package marking and labeling exceptions in § 172.336(d) and § 172.514(c), the transport vehicle must be marked in accordance with § 172.302(a).

I hope this information is helpful.

Sincerely,

Ben Supko
Acting Chief, Standards Development Branch
Standards and Rulemaking Division
