What is Freight Class?

A standardized freight code must be used when shipping products as LTL (less-than-truckload) freight. This code, which is published by the National Motor Freight and Traffic Association, allows carriers to quickly identify qualities of the shipment and assist with transportation logistics.

FAQs

Do all LTL shippers use NMFC freight classes?

Almost all U.S. LTL carriers use NMFC freight classes, although some are attempting to move to a dimensionally-based system.

What is the best way to calculate your freight class?

Working with a 3PL like Koho can help you accurately determine your freight class so you can avoid re-classification fees with the carriers. For more information on the freight class system, go to the National Motor Freight and Traffic Association.

Can I always use density to find the right NMFC class?

No. While density is one of the primary factors in determining NMFC freight class, other factors, such as value, are also used in making that determination. Gold bars, for example, are very dense, but they fall into shipping class 500 along with very low-density items because of their high value.
