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.
Some items, such as car transmissions, have a specific class no matter how heavy or big they are. This is called a fixed class. Items can be assigned a fixed class if the value and transportability very rarely change.
