Dear Mr. Baird:
This is in response to your January 22, 2001 letter regarding the requirements for use of foreign made
cylinders under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically you
ask whether the provisions of § 173.301(i)(1) stating that a charged cylinder manufactured outside the
US may not be offered to, from or within the US unless it has been manufactured, inspected and tested
in accordance with the applicable DOT specification as set forth in Part 178 applies to a foreign made
cylinder of not more than 4 fluid ounce capacity shipped as a limited quantity under § 173.306(a)(1).
The answer is no. As provided by § 173.306(a)(1) a compressed gas may be offered in a non-
specification container of not more than 4 fluid ounces capacity. The provisions of § 173.301 pertain
only where a DOT specification cylinder is required.
I hope this information is helpful.
Sincerely
Transportation Regulations Specialist
Office of Hazardous Materials Standards
