Fireworks Sold and Transported for Personal Use

Pipeline and Hazardous Materials Safety Administration · Oct 1, 1999 · Reference No. 99-0197

PHMSA says to use caution with this letter.

Interprets: 49 CFR § 171.1

Reggie’s quick take

Someone asked whether the Hazardous Materials Regulations apply to fireworks sold and transported for personal, non-commercial use. The agency said they do not. Fireworks sold to customers for personal use and carried by those people in their own vehicles are not subject to the HMR. State or local rules may still apply.

Written by AI (Claude) on Oct 22, 2026. Robots make mistakes and leave things out, so the letter below is what counts. Not legal advice.

This is in response to your letter dated July 9, 1999, concerning the applicability of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) to fireworks sold and transported for personal, non-commercial use.

Under Federal hazardous materials transportation law (49 U.S.C. 5101 et seq.), the Secretary of Transportation has authority to promulgate regulations to protect the Nation against risks inherent in the transportation of hazardous materials in commerce. The HMR govern the transportation of hazardous materials in interstate, foreign, and intrastate commerce. The transportation of fireworks that are sold to customers for personal, non-commercial use and transported by such persons in their personal vehicles is not subject to the HMR. Although such shipments are not subject to the HMR, they may be subject to certain state or local requirements.

A letter of interpretation applies the regulations to the facts the requester described. It isn’t a regulation and isn’t legal advice. The agency’s copy.
