Dear Mr. Parker:

This is in response to your April 24, 2008 inquiry requesting clarification regarding the Class 7 (radioactive) materials marking requirements under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically you ask whether a shipper is required to mark a package in accordance with § 172.310(b) if the package specification marking required by

§ 178.350 is already present.

It is not necessary that package marking entries required by Part 172, Subpart D be separate and distinct from those specified in § 178.350(c). A packaging properly marked "USA DOT 7A Type A" in accordance with §§ 178.3 and 178.350 would satisfy the requirements in

§ 172.310(b).

We will address this issue in a future rulemaking.

I hope this information is helpful. Please contact us if you require additional assistance.
