- What it does
PHMSA proposes to update the Hazardous Materials Regulations to adopt certain international regulations and standards related to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations, and vessel stowage requirements. These proposed amendments are intended to maintain consistency with the latest international regulations and standards, to reduce costs to entities or individuals within the United States, and to lower the cost of regulations on the U.S. economy.
