Almost all U.S. LTL carriers use NMFC freight classes, although some are attempting to move to a dimensionally-based system.
Freight class 50 is the least expensive because it refers to the freight that is easiest to transport for the carriers.
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.
