Dear Mr. Biehl:

This responds to your letter requesting clarification of the IBC marking requirements under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask whether the portable tank marking requirements in § 172.326 also apply to an IBC. In addition, you ask for confirmation that if the identification number markings required by § 172.302(a) on an IBC are not visible, the transport vehicle or freight container must be marked as required by § 172.332 on each side and each end with the identification number specified in the § 172.101 Table.

The marking requirements specified in § 172.326 apply only to portable tanks. In addition, your understanding of the identification number marking requirements for an IBC in § 172.33 1 and 172.332 is also correct.

I trust this satisfies your inquiry. Please contact us if we can be of further assistance.
