Why Is My Freight Class Important?

The National Motor Freight Transportation system catalogues and equitably groups all commodities moving into 18 classes (class 50 through 500) according to their “transportability”. These classes are based on four transportation characteristics prescribed by the ICC and The Department of Transportation’s Surface Transportation Board. These characteristics are as follows: (1)density, (2) stowability, (3) ease or difficulty in handling, and (4) liability.

If you need help in determining what your actual freight class is, please call GMG for personalized help at logistics@gmgtransport.com , 1-800-826-4321, or contact your Account Manager.

You can learn more about freight classifications by visiting The National Motor Freight Traffic Association, Inc. at www.nmfta.org.
