What is a freight class/NMFC code?
Your less-than-truckload (LTL) freight shipping class is a number established by the National Motor Freight Classification (NMFC). It’s also known as your NMFC classification or NMFC code.
Your freight class helps determine your shipping cost.* It’s calculated based on how difficult your commodity is to ship and how much liability is involved.
Classes are a freight shipping industry standard. They’re set by the NMFC tariff, which is a publication for motor carriers containing rules, descriptions and ratings of all commodities.
How to determine freight class
Freight class is calculated according to your commodity's transportation characteristics, including:
Density — How much it weighs in relation to its size
Liability — Its value and whether extra security precautions are needed to safeguard it against theft
Handling — If it requires special loading equipment or precautions
Stow-ability — How it fits in the trailer with other freight
There are 18 classes, numbered 50 to 500. A lower class number generally means a lower shipping
cost — because your item is easier to ship.

Note: When you ship items with different classes on the same pallet, the shipment defaults to the highest class of those items. For example, if you're shipping car accessories (class 60) with car covers (class 100) on the same pallet, the entire pallet is class 100. |

Why is freight class important?
You’ll need your freight class code in order to get a rate quote or create an online
freight shipping label or Bill of Lading.
If you don’t include your freight class, or don’t use the right class, it’s usually caught when your shipment is inspected. Then your class and shipping rates are adjusted accordingly. Incorrect classification may add fees to your shipment costs. See items 980 and 981 in the FXF 100 Series Rules Tariff for more information.
