Company profile
FMCSA L&I filing evidence — not a shipper certificate of insurance (COI). Cargo (BMC-34) is primarily an HHG / household-goods requirement; general freight carriers often have none.
BMC-84 is a surety bond; BMC-85 is a trust-fund agreement. Required for property brokers / freight forwarders — not motor-carrier BIPD liability insurance.
Based on FMCSA authority grant of 2013-06-04 (2,000+ days). Published gates only — not a guarantee they will accept. Confirm with the broker.
