Department of Transportation Updates Regulations to Improve Safety and Supply Chains

Friday, April 12, 2024

PHMSA 04-24


Streamlined requirements to save an estimated $50 to $130 million in shipping costs.

WASHINGTON – The U.S. Department of Transportation’s (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) announced it published a new Final Rule that harmonizes Federal Regulations with international standards that the Agency helped establish. The action improves safety, streamlines the transport of essential products — including medical supplies, batteries, and components used in manufacturing — and encourages shippers to package goods more efficiently. 

“The safe transportation of hazardous material like batteries and components used in manufacturing is integral to our supply chains and our economy,” said U.S. Transportation Secretary Pete Buttigieg. “This new rule improves safety, keeps the U.S. competitive on the global stage, and cuts shipping costs to the benefit of consumers nationwide.” 

The final rule will help reduce greenhouse gas emissions and supply chain disruptions by allowing the transport of more goods in fewer trips and aligning hazardous materials regulations requirements with anticipated increases in the volume of lithium batteries transported in domestic and international commerce due to the electrification of the transportation and other economic sectors. The rule also helps lessen the economic disadvantages faced by American companies that, when competing in foreign markets, are forced to comply with different or conflicting requirements or forgo exporting internationally altogether. 

“This regulatory update actually improves safety and environmental benefits while reducing red tape for businesses,” said PHMSA Deputy Administrator Tristan Brown. “It will also help improve supply chains and reduce prices for everyday Americans.”

Amendments to the rule include changes to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations, and vessel stowage requirements. These amendments are necessary to facilitate the transport of hazardous materials in domestic and international commerce.

The Final Rule is currently available in the Federal Register.

The Pipeline and Hazardous Materials Safety Administration’s mission is to protect people and the environment by advancing the safe transportation of energy and other hazardous materials that are essential to our daily lives. Please visit for more information.
