What it does

PHMSA is amending the Hazardous Materials Regulations (HMR) by streamlining the classification and approval process for transporting certain low-hazard fireworks, revising the criteria for small arms cartridges to include tracer ammunition as eligible for self- classification, designating the PHMSA portal as the sole method to submit applications for all explosives approvals, and authorizing voluntary termination of an explosive approval by the approval holder.
