The National Motor Freight Classification (NMFC) is the freight classification system devised by the National Motor Freight Traffic Association (NMFTA) and is used for all interstate, intrastate, and foreign commercial movement of LTL cargo. NMFC codes provide standardized freight classes to determine the ease of transport of many of the wide variety of commodities that are shipped together in LTL shipments.
Every commodity has both a freight class and a NMFC code. Freight class represents a category of items while NMFC codes relate to specific commodities within each of the 18 freight classes.
Apparel ranges between NMFC freight class 100 and 175.
