On July 26, 2022, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published their harmonization amendment HM-215P [Docket No. PHSMA-2019-0030 (HM-251P)]. 

The intention of this final rule is to align the Hazardous Materials Regulations (HMR) with the international regulations and standards. The regulation adopts various changes including changes to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations, and vessel stowage requirements. 

It is expected that this final rule will facilitate transport and remove hurdles when transporting both domestically and internationally as well as including assist with the transport of medical materials associated with the COVID-19 virus and the anticipated increase in transport of lithium batteries. 

Some of the noteworthy changes include: 

  • Incorporation by reference ICAO, IMDG, UN Model Recommendation, and IAEA (International Atomic Energy Agency)
