What Is an NMFC Number?
An NMFC number is a code used in the shipping industry to categorize commodities according to their transportation characteristics. NMFC numbers specify minimum packaging requirements and are widely used to assign shipping rates to different commodities.
An NMFC number is assigned to a commodity based on an evaluation of the commodity’s value, its density, its on-loading and off-loading requirements, and the ease with which it can be stowed safely on board a transport vehicle. NMFC numbers are assigned on a scale that ranges from 50 to 500, with a lower number corresponding to relatively low-value, high-density and durable goods. NMFC stands for National Motor Freight Classification, a system overseen by the National Motor Freight Traffic Association.
