BMC-91X
By Korey Sharp-Paar · Reviewed by the Fast Trucking Compliance team
Definition
BMC-91X is the FMCSA financial-responsibility filing the insurer files for hazmat motor carriers transporting hazardous materials in bulk. It mirrors BMC-91 but lists the higher hazmat liability limit ($1,000,000 for oil hazmat, $5,000,000 for non-oil hazmat) required under 49 CFR Part 387.9. 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.
