PHMSA · 49 CFR 107.601 · Registration year: July 1 – June 30

Do I need PHMSA hazmat registration?

If you offer or transport hazardous materials above certain thresholds — or any quantity that requires placarding — you must register with PHMSA and renew every year. This free 60-second check tells you whether you're registrable and which fee tier applies ($275 small business vs $2,600).

2026–27 changes: PHMSA no longer accepts paper forms or check payments, and partial refunds are no longer issued — everything is electronic via the PHMSA Portal (Login.gov + MFA). Fees: $275/yr small business & non-profits, $2,600/yr all others; multi-year $525/$5,175 (2yr), $775/$7,750 (3yr).
Step 1 · Which trigger applies?

Registration under 49 CFR §107.601 is triggered by type and quantity. Pick whatever your operation trips:

Step 2 · Business size

Do you meet PHMSA's small-business / not-for-profit definition (49 CFR §107.612)?
