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.

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.

Does stackability affect freight class?

Yes. If your shipment can be stacked, it allows the carrier to fit more freight into their truck.
