What is the MCS-150B form?

The FMCSA registration process mandates that companies specify the type of business operation that they plan to establish. In an example,  Motor Carrier, Broker, Shipper, Freight Forwarder and/or Cargo Tank Facility. The responsibilities of the FMCSA include monitoring and enforcing compliance with the Federal Motor Carrier Safety Regulations and the Hazardous Materials Regulations governing both safety and financial responsibility.

Why Should I File the MCS-150B Form?

You should only submit the MCS-150B if you transport the specific type and quantity of hazardous materials. Also, there is no easy way to change this filing, and your CSA scores will be based upon the higher hazardous materials compliance threshold that applies to any carrier transporting hazardous materials. A single carrier entity should never file both the MCS-150 and the MCS 150B. You should submit only one of the two.

Keep in mind that nothing stops carriers from updating their information whenever necessary; if you come across necessary changes in your company that affects your MCS-150 or MCS-150B information you should immediately update your information.
