Auto Parts NMFC Codes & Freight Class

The Standard for Freight Identification and Classification

The National Motor Freight Classification (NMFC) is a standard 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.”

The four transportation characteristics were prescribed by the Interstate Commerce Commission (ICC) in 1983 and then mandated by its successor agency, the Surface Transportation Board (STB). Although the ICC no longer exists and the STB no longer regulates the classification process, by analyzing commodities on the basis of these characteristics and ONLY on the basis of these characteristics, the NMFC provides both carriers and shippers with a standard by which to begin negotiations and greatly simplifies the comparative evaluation of the many thousands of products moving in today’s competitive marketplace.

The Standard for Packaging, Rules and Bills of Lading

The NMFC specifies minimum packaging requirements to ensure that goods are adequately protected in the motor carrier environment and can be handled and stowed in a manner that is reasonably safe and practicable. It contains various rules that govern and otherwise relate to the classification and/or packaging of commodities as well as procedures for the filing and disposition of claims. It also contains the Uniform Straight Bill of Lading and the North American Uniform Through Bill of Lading, including their Terms and Conditions.
