LTL Shipping: Why Freight Class Matters
In LTL shipping, freight class directly determines your shipping rate. Getting classified incorrectly can result in reclassification fees, unexpected charges, or overpaying for shipping.
How LTL Pricing Works
LTL carriers use a combination of freight class, weight, distance, and lane to calculate rates. A shipment classified as Class 100 costs significantly more per hundred pounds (CWT) than the same weight classified as Class 50.
Steps to Determine Your LTL Class
- Measure your shipment: Length × Width × Height (inches)
- Weigh the shipment (include pallet weight)
- Calculate density: Weight ÷ (L × W × H ÷ 1,728)
- Match density to the NMFC class chart
- Check if your commodity has a specific NMFC code that overrides density
Pro Tip
Always include pallet dimensions and weight in your calculation. Carriers measure the entire shipment as loaded, not just the product itself.
