Does this apply to your product?

It likely does if you can answer yes to each of these:

  • Is it made of plastic?
  • Is it a trim piece that attaches to the exterior body of a vehicle?
  • Is its purpose to enhance the vehicle's exterior appearance?

A no to any of them can mean a different code. A licensed broker can classify your product.
