The National Motor Freight Classification^® (NMFC^®) is a tool that provides a comparison of commodities moving in interstate, intrastate and foreign commerce. It is similar in concept to the groupings or grading systems that serve many other industries. Commodities are grouped into one of 18 classes—from a low of class 50 to a high of class 500—based on an evaluation of four transportation characteristics: density, stowability, handling and liability. Together, these characteristics establish a commodity’s “transportability.”
