What is shipping class / freight class illustration

Freight shipping class or freight classification is a number assigned to less than truckload (LTL) shipments going within US, or cross-border. Freight class is based on weight, size, density, handling, value, and assumed risk/liability for hauling.

The freight class may be NMFC-based or density based. There are 18 freight classes. Each product is given a class ranging from 50-500 determined by the National Motor Freight Classification® (NMFC®) system.

Freight shipping class allows carriers in the United States to use uniform pricing. Lower class usually implies lower shipping cost.

During quoting, please write the correct class and the NMFC code on the quoting page. If your shipment’s actual class differs from the class used during quoting, the carrier will adjust your final bill with extra charges.

To get an idea of what your freight shipping class may be, please use Freightera Class Calculator, and Freightera Density Calculator.
