National Motor Freight Classification (NMFC) is the freight classification system that was created by the National Motor Freight Traffic Association (NMFTA) and is used for all interstate, intrastate, and foreign commerce movement of LTL cargo. NMFC codes provide standardized freight classes to determine the transportability of most of the countless different commodities that are shipped together in LTL shipments each year.
Adding NMFC code to a shipment is technically optional, but the NMFC codes can help avoid reclassification and ensure you're using the correct freight class number.
NMFC stand for National Motor Freight Classification. This is a classification system used for interstate, intrastate, and foreign commerce movement of LTL shipments. You can learn more on our freight classes pages.
