Hazardous Materials: Streamlining Requirements for the Approval of Certain Energetic Materials
§ 01 Summary
PHMSA amends the Hazardous Materials Regulations to streamline classification and approval procedures for certain low-hazard fireworks and to allow small arms cartridges with tracer ammunition to be self-classified under revised criteria. The rule also makes the PHMSA portal the exclusive submission method for explosives approval applications and allows approval holders to voluntarily terminate an explosives approval.
§ 02 Why this matters
The rule changes compliance procedures under the HMR by expanding self-classification eligibility for certain ammunition, altering approval requirements for low-hazard fireworks, and requiring all explosives approval applications to be submitted through the PHMSA portal. These changes affect how regulated entities obtain, maintain, and terminate approvals for transporting explosive and energetic materials.
