Hazmat registrants

Every company registered with PHMSA to offer or carry placarded hazardous materials (49 CFR 107 Subpart G): its Function Specific Hazmat Permit Profile with registration status, DUNS, modes, the FMCSA carrier it matches and its PHMSA incident history.

Sources: PHMSA Hazmat Registration list (updated monthly), FMCSA census, PHMSA 5800.1 incident reports. FMCSA carrier matches are by company name and ZIP; functions say what they rest on. Not legal advice.
