Transportation of non-hazardous materials containing radionuclides

This is in response to your letter dated November 17, 2007 regarding the shipping paper and marking requirements contained in the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) that are applicable to a portable tank containing the residue of a hazardous material. Specifically, you ask for confirmation that the allowance in § 172.203(e)(1) to include the words "RESIDUE: Last Contained" as part of the description on the shipping paper does not require the proper shipping name marking, provided by § 172.326(a), to be supplemented with the words "RESIDUE: Last Contained."

Your understanding is correct. You are not required to supplement the proper shipping name marking on a portable tank containing residue of a hazardous material with the words "RESIDUE: Last Contained." The requirement provided in § 172.203(e)(1) allows you to include the words "RESIDUE: Last Contained" on the shipping paper in association with the basic description of the hazardous material previously contained in the package.
