What is a Freight Class?
Freight class is a standardized shipping category defined by the NMFC (National Motor Freight Classification). It helps US carriers determine shipping costs based on four factors: density, stowability, handling, and liability. Lower classes like Class 50 are dense and cheaper to ship, while higher classes like Class 500 are for light, fragile items. Using a professional and easy LTL Class Calculator ensures your shipment is categorized correctly before it leaves the dock.
