Specifically, you ask whether the Canadian exclusive use labeling exemption of Section 16(5)(c) of The Canadian Nuclear Safety Commission Packaging and Transport of Nuclear Substances Regulations, which closely mirrors that of 49 CFR 173.427(a)(6)(vi), is accepted in the United States or must each package in the shipment be labeled with appropriate category labels in accordance with the International Atomic Energy Agency (IAEA) Safety Series 6 paragraphs 440 - 442, or IAEA TS-R-1 paragraphs 541-545. As you correctly stated in your letter, § 171.12a(a) and (b) provides for hazardous material shipments originating in Canada, packaged and labeled in accordance with Canadian Transport Dangerous Goods (TDG) Regulations, to be offered fot transport into the United States, if the relevant conditions and limitations from § 171.12a(b)(1) through (b)(18) are met. The condition prescribed in § 171.12a(b)(8) states that a Class 7 (Radioactive) material must conform to the provisions of § 171.12(d), which require conformance with the IAEA Safety Series 6 or TS-R-1. "RADIOACTIVE SCO-I," as appropriate. Therefore, in your scenario, your packages marked TS-R-1, in paragraph 540, authorizes the packages to be marked "RADIOACTIVE LSA-I" or "RADIOACTIVE-LSA-I: EXCLUSIVE USE" are acceptable. Your wording "EXCLUSIVE USE" is considered to be additional information. I hope this information is helpful. Sincerely, thathe z mitchell Hattie L.
