Dear Ms. Messana:

This responds to your letter regarding the use of requalified foreign cylinders for the packaging of toxic by inhalation liquids under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask whether cylinders manufactured in accordance with the European ADR standard are permitted without further approval to package a Division 6.1, Hazard Zone B liquid (Chloropicrin, UN1580) under §§ 173.40 and 173.227 of the HMR once they are requalified in the United States as specified in § 171.23. Once successfully retested and refilled, the cylinders would be exported to a destination outside the United States.

The answer to your question is no. The conditions for packaging materials toxic by inhalation under international standards are specified in § 171.23(b)(10) which requires such materials to be packaged in accordance with the HMR. Section 173.227(a) specifies that a Hazard Zone B toxic liquid must be packaged in a seamless or welded DOT specification cylinder or a seamless UN standard cylinder conforming to § 173.40. Section 173.40 prescribes the specific requirements for the packaging of toxic materials in cylinders.

I trust this satisfies your inquiry. Please contact us if we can be of further assistance.

Sincerely,

Hattie L. Mitchell
