The ATA owns the NMFC copyright and contracts with the National Motor Freight Traffic Association to maintain it. The NMFC assigns each commodity or group of commodities moving in commerce, and having comparable transportation characteristics, to one of 18 separate classes. The class rating of a product is determined based on its transportation characteristics, such as density, stowability, ease or difficulty in handling, and liability.
