Yes. All entities with a USDOT number are required to file a biennial update every two years according to the prescribed schedule, by the last day of the month.

You can file a biennial update prior to the time that an update is due. FMCSA considers any update of an MCS-150 or MCS-150C that was completed by a motor carrier, Intermodal Equipment Provider (IEP), or carrier that has been issued a Hazardous Materials Safety Permit (HMSP) at any time during the 12 months immediately preceding the biennial update due date to satisfy the biennial update requirement.
