Freight Class

The National Motor Freight Classification (NMFC) details 18 freight classes, where Class 50 is the lowest and Class 500 is the highest. The higher the class, the higher the rate for every hundred pounds you ship.
UPS bases freight class on four shipment characteristics:

  1. Density: Are you shipping a pallet of stone or a pallet of ping pong balls?
  2. Stowability: What are the dimensions of your shipment? Does it have irregular angles so that it takes up more space than normal?
  3. Handling: Is the freight palletized?
  4. Liability: Are you shipping valuable electronic equipment or boxes of used clothing?

If you need additional help to determine your freight class, please contact UPS Customer Service at 1-800-333-7400. You can also find more detailed information about freight classes through the National Motor Freight Traffic Association (NMFTA).
