What is Freight Class?

When you ship your products as LTL (less-than-truckload), you have to assign your shipment a freight code. This is a standard code created by the National Motor Freight and Traffic Association which allows carriers to identify qualities of the shipment and assist with transportation logistics.

FAQs

What are the NMFC codes?

Created and maintained by a nonprofit organization called the National Motor Freight Traffic Association (NMFTA), National Motor Freight Classification (NMFC) is a classification system used for interstate, intrastate, and foreign commerce movement of LTL shipments. You can learn more on our freight classes pages.

How is freight class calculated?

The first step in determining your freight class is to take measurements. Measure the height, width and depth of your shipment then multiple those three measurements together for the total cubic feet. Then divide the total cubic inches by 1,728 (the number of cubic inches in a cubic foot). Finally, divide the weight (in pounds) of the shipment by the total cubic feet.

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.
