New LTL Freight Class Rules Take Effect Today

Effective Date: July 19, 2025
What’s Changed
- The National Motor Freight Classification (NMFC) system has shifted to a density-first approach.
- New 13-sub density scale replaces the former 11-tier system.
- Examples include:
- Sub 11: 30–<35 lb/ft³, Class 60
- Sub 12: 35–<50 lb/ft³, Class 55
- Sub 13: ≥50 lb/ft³, Class 50
- Over 2,000 NMFC items revised or consolidated for greater clarity and simplicity.
Why It Matters
- More accurate pricing: Dense shipments are more cost-efficient; low-density freight will see higher charges.
- Clearer classification process: Simpler unless special handling or liability is involved.
- Reduced reclassifications: Fewer billing surprises, fewer disputes.
What Shippers Should Do
- Check NMFC updates: Use the new ClassIT+ system.
- Calculate density: Divide shipment weight by cubic volume (lb/ft³).
- Update internal tools: Ensure TMS, BOLs, and quoting systems reflect the new structure.
- Optimize packaging: Denser loads mean lower classification and costs.
- Train teams: Educate staff on measuring dimensions and using ClassIT+.
Bottom Line
The July 19, 2025 NMFC updates prioritize a streamlined, density-based freight classification system. While these changes aim to simplify pricing and reduce disputes, shippers must take action now, by measuring accurately, revising systems, and optimizing packaging, to stay competitive and cost-efficient.
