Created and maintained by a nonprofit organization called 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 on our freight classes pages.
CWT stands for hundredweight. LTL shipments are priced “per 100 pounds,†“cwt,†or “per hundredweight.†This means that a 400 lb shipment priced at $25 CWT would cost $100, not including accessories or specialty services.
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 determine your shipment is.
