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 National Motor Freight and Traffic Association has 18 freight classes numbered 50 to 500. The lower the freight class, the lower the cost of transporting that freight.
NOI stands for Not Otherwise Indicated. This is used when a commodity does not have an NMFC code. In these cases, density is usually used to determine freight class.
