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.

If you don't include an NMFC code on your BOL, it is very likely that your carrier will charge you a reclassification fee and charge you the cost of shipping the freight they they determine your shipment is.
