What is shipping class / freight class illustration

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

The 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.

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 class may be, please use Freightera Class Calculator, and Freightera Density Calculator.

The best way to be 100% sure of the CORRECT CLASS is to contact us with the description of your product (dimensions, weight, what the product is, what is it used for, what is it made of, how is it packaged), and our shipping experts will help you!
