Step-by-Step: How to Calculate Freight Class 2025

Follow this guide for accuracy. **Freight class calculation 2025 ensures compliant, low-cost shipping.**

  1. Measure pallet: L x W x H in inches; convert to cu ft (÷1728).
  2. Weigh accurately: Scale entire pallet.
  3. Compute density: lbs / cu ft; round down.
  4. Check NMFC: Match density + handling traits.
  5. Verify: Use online class calculators.

Avoid these traps. **Freight class errors 2025 lead to audits and 20% rate hikes.**

  • Mistake: Guessing density → Fix: Always measure.
