PHMSA Proposes Terminating M- and R-Hazmat Packaging Approvals

Posted on 11/21/2017 by Roger Marks

Dented_Drum_leaking3.jpgIn the Federal Register this week, PHMSA proposed to terminate approvals issued to packaging manufacturers and reconditioners, known as M- or R-numbers. The M- and R-numbers eliminated will be those PHMSA issued without an expiration date.

These approvals will be terminated as of November 17, 2018.

Companies still using the M- or R-numbers affected are instructed to contact PHMSA with justification for why their approval should not be eliminated per 49 CFR 107.703(c)(1). Or, companies can apply for a modification to their approval. Modified approvals will be issued with an expiration date of 5 years.

Companies may continue using their R-numbers even after the approval is modified and a new M-number is issued.
PHMSA believes eliminating these approvals will standardize the approval process and expiration of approvals and make it easier for PHMSA to “regularly review approval documents and track changes.”

M and R Approvals for Hazmat Packaging

PHMSA issues registration numbers to companies that manufacture or recondition hazardous materials packaging. Today, these registration numbers are known as M-numbers. In the past, R-numbers were issued to package reconditioners. These registration numbers can be used to mark hazmat packagings, in lieu of using the manufacturer or reconditioners complete name and address. [49 CFR 178.503]
