Building a Trailer?

​If you intend to manufacture trailers, there are a number of items you need to consider as well as items that you are ​legally mandated to complete.

If your trailer will be used on roadways, you are required to do the following:

  • Obtain a World Manufacturing Identifier (WMI) from the Society of Automotive Engineers (SAE)
  • National Highway Traffic Safety Administration (NHTSA) Registration
  • State Registration and Regulation
  • Federal Regulations

You will also want to consider the following:

  • Finding suppliers and service providers 
  • Insurance
  • Components
  • Engineering services
  • Warning Labels

We're Here To Help: 

This may all seem overwhelming, but NATM helps its members with this process. As a new manufacturer, NATM can help provide you with the information you need to obtain your WMI and VIN and contact information for your state agency.

Often considered the most significant benefit is the compilation of applicable Federal Motor Vehicle Safety Standards, industry regulations, and best practices which are included in NATM’s Guidelines. This resource is given to each member along with annual updates.

Moreover, NATM compliance consultants visit member facilities every two years to ensure manufacturers have the processes in place to build trailers in accordance with these regulations. For more information about NATM’s Compliance Verification Program, click here.
