PHMSA proposes to align HMRs to international standards

Agency seeking comments on proposed revisions

Posted August 26, 2016

The Pipeline and Hazardous Materials Safety Administration (PHMSA) is seeking comments on its proposed revisions to the U.S. Hazardous Materials Regulations (HMRs) to maintain alignment with international standards. The agency says the changes facilitate the safe transport of hazardous materials in international commerce.

The proposed changes include revisions to:

  • Proper shipping names,
  • Hazard classes,
  • Packing groups,
  • Special provisions,
  • Packaging authorizations,
  • Air transport quantity limitations, and
  • Vessel stowage requirements.

The proposed rule is based on recent revisions to the United Nations Model Regulations, International Maritime Dangerous Goods Code, and the International Civil Aviation Organization's Technical Instructions for the Safe Transport of Dangerous Goods by Air. The U.N. Model Regulations are amended and updated biennially.

Comments must be received on or before 60 days after publication in the Federal Register.
