Reference No. 16-0096

Dear Mr. Shaw,

This letter is in response to your May 31, 2016, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to limited quantity packages of Class 7 (radioactive) materials transported by passenger-carrying aircraft. Although not clearly stated, we believe you ask whether the restrictions on the transport of radioactive materials in passenger-carrying aircraft prescribed in § 175.700(a) apply to limited quantity packages prepared in accordance with §§ 173.421 and 173.422.

The answer is no, provided your package is prepared in accordance with § 173.421 and also meets the applicable requirements in § 173.422. That said, as prescribed in § 175.700(a), no person may carry any other radioactive material, such as a Type A or Type B quantity, aboard a passenger-carrying aircraft unless that material is intended for use in, or incident to research (See §171.8 of this subchapter), medical diagnosis or treatment. Section 175.700(a) provides exceptions for radioactive materials prepared in accordance with §§ 173.4a, 173.422, and 173.423, which may be shipped by passenger-carrying aircraft regardless of their end use and are not subject to any other requirements of the HMR, including §§ 173.448(f) and 175.700(a).

I hope this information is helpful. Please contact us if we can be of further assistance.
