What is Freight Class?

When shipping your products as LTL (less-than-truckload), you’ll need to assign your shipment a freight code. This is a standardized code published by the National Motor Freight and Traffic Association that allows carriers to identify qualities of the shipment and assist with transportation.
Ship mechanical movements accurately by using the information below:

FAQs

Where can I find a freight code list?

The National Motor Freight Traffic Association (NMFTA) publishes a list of freight class designations, codes, and subclasses for commonly shipped items (https://classit.nmfta.org/). A subscription is required to view this list. You can read more about freight classes at Koho for free on our freight classes pages.

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.

How is freight class determined?

NMFC freight classes are determined using four factors: density, handling, stowability, and liability. All of these factors affect the cost to the carrier of shipping goods.
