Dear Ms. Burns:

This is in response to your letter requesting clarification of requirements in the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the transport of non-DOT specification cylinders filled with a compressed gas and transported in a port area.  Specifically you ask if you can receive bromotrifluoromethane in non-DOT specification cylinders and subsequently transport the cylinders and transfer the bromotrifluoromethane to a DOT specification cylinder prior to leaving the port area in accordance with the provisions of § 171.25(d).

The answer is no, § 171.25(d) does not apply to the activities you describe, as it only authorizes the transportation of non-DOT specification cylinders, not the discharge of their contents. Conversely, § 171.23(a)(3) applies to transportation of imported cylinders for discharge within a single port area. In accordance with § 171.23(a)(3), imported non-DOT specification cylinders may be transported within a single port area and discharged if: (1) the Associate Administrator grants an approval for this activity; (2) the cylinders are certified as conforming with the transportation regulations of another country; (3) they are transported within a closed freight container; (4) the importer certifies that they provide an equivalent level of safety as comparable DOT specification cylinders; and (5) the cylinders are not refilled for export except in compliance with § 171.23(a)(4).

An application for an approval should contain a description of what is requested, operational and quality controls, packaging authorizations, and any other documentation sufficient to support the application. You may review complete requirements regarding approvals in §§ 107.701-107.717.

I hope this information is helpful. If you have further questions, please do not hesitate to contact this office.
