What are Freight Classes?

Freight classes are designed to help you get common standardized freight pricing for your shipment when working with different carriers, warehouses and brokers.   Freight classes are defined by the National Motor Freight Traffic Association (NMFTA) and made available through the NMFC or National Motor Freight Classification.

Freight classes (there are 18 of them) are based on weight, length and height, density, ease of handling, value and liability from things like theft, damage, break-ability and spoilage. For the most part, the lower the NMFC class number, the lower the freight charge.  Part of FML’s job is to help you figure out your NMFC freight class, insuring the specialized code is correct. This insures that you get correct and consistent pricing for your freight.  The following table describes the NMFC classes and is meant for general guidance in picking your freight class, a number of factors influence what class your shipment ends up in.  You should contact FML Freight Representative to determine an accurate freight class.
