FAQs

Where can I find freight class code lookup?

The National Motor Freight Traffic Association (NMFTA) annually publishes a list of freight class designations, codes, and subclasses for commonly shipped items (https://classit.nmfta.org/). To access this list, you are required to pay a subscription fee. Learn more about freight classes for free on our freight classes pages.

What happens when a freight class code is wrong?

It might be tempting to declare that your shipment is a lower freight class than it actually is in order to secure a lower price, however, carriers will re-classify your freight for accuracy and charge you a fee for having to do so.

Can how I pack my shipment affect freight class?

Yes. How your freight is packaged can signifcantly affect the cost of your shipment. Contact Koho for questions about specific commodities and best packaging practices.
