Determining Freight Class
Determining the correct freight class is essential for accurate shipping costs and unexpected fees. Freight class is a standardized system in North America (typically NMFC-based) that categorizes goods based on transportability.
Key Factors in Freight Classification:
Density (Primary Factor)
Calculate: Weight (lbs) / Volume (cubic feet)
Example: A 500-lb pallet (48" x 40" x 60") has a volume of 53.3 cu ft (L x W x H ÷ 1,728)
Density = 500/53.3 = 9.4 lbs/cu. ft.
Storability
Irregular shapes, hazardous materials, or perishable goods may increase class.
Handling
Fragile, heavy, or awkward items may require special handling (higher class)
Liability
