Yes — based on the most recent FMCSA sync, Submex LLC has active broker authority. Authority status can change at any time; always verify on the FMCSA SAFER system before signing a carrier-broker agreement.

Federal regulations require every property broker to maintain a $75,000 surety bond (BMC-84) or trust agreement (BMC-85) on file with FMCSA. This protects carriers from non-payment. Active broker authority generally means a valid bond is on file — verify current bond status via FMCSA's L&I (Licensing & Insurance) public search.

A freight broker holds FMCSA broker authority (MC-FF), legally arranges transportation between shippers and carriers, and earns commission from the rate spread. A truck dispatcher works on behalf of the carrier — finding loads on load boards, negotiating rates with brokers (like Submex LLC), and handling paperwork. Brokers represent shippers; dispatchers represent carriers. See O Trucking's guide on dispatcher vs. freight broker, or learn about O Trucking's dispatch services for carriers.

Brokers source carriers through: (1) FMCSA-verified carrier directories where MC numbers and safety records are pre-checked, (2) load boards (DAT, Truckstop) that match active carriers to posted freight, (3) direct relationships with dispatch services that represent multiple carriers, and (4) referrals from current carriers. O Trucking maintains an FMCSA-licensed carrier directory — see active carriers based in Arizona. We also dispatch hundreds of owner-operators and small fleets — see O Trucking dispatch services.

Before accepting any load, do the full broker verification check: (1) confirm active MC broker authority on FMCSA SAFER, (2) verify BMC-84 surety bond ($75K minimum) or BMC-85 trust on FMCSA L&I, (3) check days-to-pay reputation on broker-credit databases, and (4) search carrier forums for fraud history. O Trucking maintains an FMCSA-licensed broker directory for Arizona with verified authority data and authority-age sorting so older, more-established brokerages surface first.
