Reference No. 19-0127

Dear Mr. Claussen:

This letter is in response to your November 6, 2019, email and subsequent phone conversation requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to excepted packages of radioactive material. Specifically, you ask whether radioactive material in excepted packages that conform to the requirements of §§ 173.421 and 173.422 must meet the specific requirements of § 173.4a.

The answer is no. The packaging authorization in §§ 173.421 and 173.422 is specific to certain limited quantities of radioactive material and is not related to the excepted quantities exception in § 173.4a. We believe the reference to radioactive materials in excepted packages in § 173.4a(b)(7) is a result of a typographical error in our effort to harmonize the HMR with changes to the international regulations (74 FR 2199; HM-218J). We plan to correct this in a future rulemaking.

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

Sincerely,

Dirk Der Kinderen
Chief, Standards Development Branch
