THE LETTERS

摘要

This letter is in response to your January 28, 2019, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) regarding filling and transporting a non-DOT specification cylinder as a private individual for personal use. Specifically, you ask whether a "dive shop" as described in your email, is subject to the HMR if it fills a foreign manufactured SCUBA cylinder solely for the personal use of an individual.
