BMC-91X

Definition
BMC-91X is the FMCSA financial-responsibility filing the insurer files for hazmat motor carriers. It mirrors BMC-91 but lists the hazmat liability limit required under 49 CFR 387.9: $1,000,000 for oil and for hazardous materials, waste, or substances not in the $5,000,000 entries, and $5,000,000 for bulk hazardous substances in cargo tanks, portable tanks, or hopper vehicles, bulk Division 1.1, 1.2, or 1.3 explosives, bulk Division 2.3 or 6.1 PG I Hazard Zone A, and highway-route-controlled quantities of Class 7. The X suffix lets FMCSA Licensing & Insurance distinguish hazmat policies during automated validation. Like every BMC filing, only the insurer can submit it electronically - the carrier never personally files. A 30-day cancellation notice from the insurer triggers automatic authority deactivation if no replacement BMC-91X arrives in time. New hazmat applicants on Form OP-1 must list a BMC-91X-eligible insurer when filing for hazmat operating authority.
