PHMSA hazmat registration: who must register

Most small hazmat operations do not know whether they're registrable — and that's the expensive mistake. Under 49 CFR Part 107 Subpart G, you must register before offering or transporting materials that meet the hazmat definition above the six-trigger threshold.

The annual deadline

Registration is annual and renews by June 30 each year (49 CFR §107.608(a)). Early registration opens June 1 each year. As of Sept 2026 the 2026–2027 cycle (Jul 1, 2026 – Jun 30, 2027) deadline has passed, so a new registrant must register before engaging in a registrable activity. Missing it means operating unregistered — an independent violation that can draw penalties up to ~$89,678 per violation (49 U.S.C. §5123).

The fee tiers

• $275/yr — small business or nonprofit (under 500 employees), $250 + $25 processing
• $2,600/yr — all other registrants

File directly on the official MOTUS portal — no third-party filing fee (PHMSA warns such services add fees on top of the government charge; the registration fee itself still applies).
