Created and maintained by a nonprofit membership organization named the National Motor Freight Traffic Association (NMFTA), National Motor Freight Classification (NMFC) is a classification system used for interstate, intrastate, and foreign commerce movement of LTL shipments. You can learn more from the experts at Koho on our freight classes pages.

The class determines the cost of the shipping. The lower the class, the lower the cost.

NMFC freight classes are determined using four factors: density, handling, stowability, and liability. All of these factors affect the cost to the carrier of shipping goods.
