What’s the Deal with NMFC Codes Today?

What’s the Deal with NMFC Codes Today?

Common questions we often hear at Echo Global Logistics when assisting clients with less than truckload (LTL) shipments revolve around evaluating freight class and avoiding reclassification charges and fees. If you’re new to shipping LTL, the class system can be difficult to navigate.

Why Does LTL Use Freight Classes?

The National Motor Freight Traffic Association (NMFTA) created an industry-wide standard for logistics professionals known as National Motor Freight Classifications, or NMFC codes, to help simplify the process of comparing different commodities and calculating LTL costs. This numeric-based system groups commodities into one of 18 different freight classes spanning from a low of class 50 to a high of class 500 based on four essential transportation characteristics:

  • Density: Density is identified by the space an item occupies in direct connection with its weight. It’s calculated by dividing the weight of the item in pounds by its volume in cubic feet. Density guidelines assign class 50 to freight that is more than 50 pounds per cubic foot (PCF). Freight with a density of less than 1 PCF is assigned class 500. The denser your freight is, the less it will cost you per pound to ship.
  • Liability: Liability has to do with how likely your freight is to be damaged or targeted for theft. Freight that is perishable or combustible is likely to be assigned a higher freight class. Commodities that are considered highly valuable, such as copper or electronics, also receive a higher freight class.
  • Stowability: If your freight is difficult to stow with other items in a shipment, this can raise the freight classification. Additionally, items that are under government regulation or are subject to certain carrier policies may not be able to ship with other items. Basically, anything that limits freight storage options results in a higher freight class.
  • Handling: If loading or unloading your freight requires special equipment due to its weight, shape, fragility, or hazardous material contents, it could be assigned a higher freight class.

These characteristics ultimately work to identify how difficult it is to transport an item. As you can see, products that are harder to ship are assigned higher classes. In other words, the higher the class, the higher the freight rates per pound.

Regardless of the initial price, a shipper’s ability to correctly label a shipment’s class code and number on a bill of lading can mean the difference between a hassle-free shipping experience and an unexpected carrier reclassification fee. Carriers are paid for the services they provide, so they might reclass your shipment, charge you for the incremental rate, and add a fee for all the trouble.

Changes to NMFC Codes

A few times each year, the NMFTA publishes changes to their existing classification catalog. Partnering with a 3PL such as Echo can help you stay in front of those changes and be prepared.

As an example, below are some changes to NMFC items from April, 2021 as well as some proposed changes to take effect in December, 2021. Allow Echo to work as your partner and alert you to upcoming changes.

On April 10, 2021, the NMFTA effected Supplement 1 to NMF 100-AU. Here’s a quick snapshot of how shippers were impacted:
