Subclasses for
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.
Density is the relationship between weight and size. A ping pong ball, which is very little material surrounding a good amount of air, is low density. Bricks, which are heavy for their size, are high density. In LTL shipping, it is commonly measured in pounds per cubic foot.
