The minimum premium for a freight broker bond is $938 for a duration of one year, as mandated by the FMCSA. The premiums charged for BMC 84 surety bonds are different for each state and applicant. An underwriter will establish the exact cost of your freight broker bond, which will be expressed as a percentage of the total $75,000 bond amount. Experienced freight brokers or forwarders who have worked in the transportation broker profession in the past may be eligible for a reduced charge because of their prior experience in the field.
