Guide to Freight Class

Download the guide to learn how freight classifications are determined. Walk through an example of how to determine a commodity's freight class (NMFC) by considering density, handling, stowability, liability.

Freight class was developed by the National Motor Freight Traffic Association, Inc. (NMFTA). Every commodity has a corresponding National Motor Freight Classification number or NMFC which is assigned a freight class. It is important to note that class alone does not contain any rates or charges for transportation services nor does it suggest rates or charges. The Commodity Classification Standards Board (CCSB) is an autonomous board that creates the NMFC numbers and amends rules and classifications as commodities change over time.
