Understanding freight class.

To establish fair measures and standardize freight pricing, the National Motor Freight Traffic Association (NMFTA) created a freight classification system for all types of commodities. This system, featuring well-defined classes, is cataloged with National Motor Freight Classification tariff, commonly referred to as the NMFC. 

Shipping commodities are grouped into 18 freight classes between 50 and 500. Shippers and carriers use the NMFC freight classifications as a common standard when setting shipping rates. 

As important as it is to understand how freight classes affect rates, be assured that a Freightquote by C.H. Robinson shipping expert is available to make your shipping experience as easy as possible.
