What is a freight class?

The National Motor Freight Traffic Association (NMFTA) has documented all types of freight commodities and classified them to create standards in freight pricing. The definitions, or classes, of freight are cataloged in the National Motor Freight Classification tariff, commonly referred to as the NMFC.

Freight shipping goods are grouped into eighteen classes between 50 and 500. The NMFC publishes, to both carriers and shippers, a common standard to provide pricing negotiations and simplifies the comparative evaluation between different types of commodities.

NMFC freight class basics

The general rule of thumb is the higher the class, the higher the rate for every hundred pounds you ship. Rates are structured so that as the weight of your shipment increases, the rate per hundred pounds decreases.
