What's Happening?
The Pipeline and Hazardous Materials Safety Administration (PHMSA) has issued a notice of proposed rulemaking to amend the Hazardous Materials Regulations (HMR) to align with international standards. This proposal, published on February 10, 2026, aims
to incorporate changes from the latest editions of the International Civil Aviation Organization Technical Instructions, the International Maritime Dangerous Goods Code, and the UN Model Regulations. Key changes include new provisions for sodium ion batteries, which will now be regulated similarly to lithium ion batteries due to their increased use. The amendments also propose updates to the hazardous materials table, including new entries for sodium ion batteries and vehicles powered by various battery types. Additionally, the proposal includes changes to the transport provisions for gases and organic peroxides, as well as new state-of-charge requirements for batteries transported by air. PHMSA is accepting public comments on these proposed changes until April 13, 2026.
Why It's Important?
The proposed amendments by PHMSA are significant as they aim to harmonize U.S. hazardous materials regulations with international standards, potentially reducing costs and improving safety in the transportation sector. By aligning with global standards, U.S. businesses involved in the transport of hazardous materials could benefit from streamlined processes and reduced regulatory burdens. The inclusion of sodium ion batteries in the regulations reflects the growing market for alternative energy storage solutions, which could drive innovation and adoption of new technologies. These changes also address safety concerns associated with the transport of hazardous materials, ensuring that the U.S. remains compliant with international safety protocols. The proposal's focus on battery regulations is particularly relevant given the increasing use of electric vehicles and personal mobility devices, which rely heavily on battery technology.
What's Next?
PHMSA is currently seeking public input on the proposed rule changes, with comments being accepted until April 13, 2026. Stakeholders, including businesses, industry groups, and safety advocates, are expected to provide feedback on the potential impacts of the amendments. The feedback will likely influence the final rule, which could be issued later in the year. If adopted, these changes will require businesses to adjust their compliance strategies to meet the new standards. The transportation industry, in particular, will need to update their practices to accommodate the new regulations for sodium ion batteries and other hazardous materials. The outcome of this rulemaking process will be closely watched by international partners and could set a precedent for future regulatory updates.
