What is Freight Class?

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

FAQs

What is the NMFC code?

The National Motor Freight Traffic Association (NMFTA) created the National Motor Freight Classification (NMFC). It is used for all interstate, intrastate, and foreign commercial movement of LTL cargo. NMFC codes provide standardized freight classes to determine the transportability of the large variety of commodities that are shipped together in LTL shipments every year.

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.

What happens if I don't put an NMFC freight class on my BOL?

If you don't include an NMFC code on your BOL, it is very likely that your carrier will charge you a reclassification fee and charge you the cost of shipping the freight they they determine your shipment is.
