What is Freight Class?
Freight class is a standardized classification system used in LTL (Less-Than-Truckload) shipping to categorize commodities. Classes range from 50 to 500, with lower classes typically being denser, easier to handle, and less expensive to ship.
Freight Class Factors
- Density: Weight per cubic foot
- Stowability: How easily items fit with other freight
- Handling: Special equipment or care needed
- Liability: Risk of damage, theft, or perishability
The 18 Freight Classes
Classes range from 50 (lowest cost) to 500 (highest cost): 50, 55, 60, 65, 70, 77.5, 85, 92.5, 100, 110, 125, 150, 175, 200, 250, 300, 400, 500.
Density and Class Relationship
- Class 50: 50+ lbs/cubic ft (bricks, cement)
- Class 100: 9-10.5 lbs/cubic ft (furniture)
- Class 250: 2-3 lbs/cubic ft (mattresses)
- Class 500: Under 1 lb/cubic ft (ping pong balls)
Why Freight Class Matters
