The National Motor Freight Classification (NMFC) sets the standard for how LTL (less-than-truckload) freight is classified. It influences rates, compliance, and operational processes across the supply chain. Starting July 19, 2025, NMFTA will implement one of the most significant updates in recent years under Docket 2025-1.
These changes aim to simplify classification, align pricing with actual density, and modernize the system. But for shippers, this update comes with big implications, especially when it comes to cost control and compliance.
What’s Changing in 2025?
1. New 13-Tier Density Scale
The current 11-break density table, which assigns freight classes based on pounds per cubic foot, will be replaced with a 13-break density scale. This change allows for finer classification adjustments and is designed for freight with no special handling, stowability, or liability concerns.
- The revised structure aims to improve fairness and accuracy in how freight is rated.
- By adding more breaks, the system reduces the “cliff effect” where small density changes caused big class shifts.
Impact:
If your products are dense and compact, you could move to a lower freight class, reducing costs. On the flip side, lightweight or oversized freight could shift upward, resulting in higher rates. This makes accurate measurements and strategic packaging more important than ever.
2. Classes 50 and 55 Added
Previously, under the density-based table, the lowest possible class was often higher than 55. With this update, Classes 50 and 55 will now apply under density rules, creating more opportunities for lower-cost classifications.
- This specifically benefits industries shipping dense freight like building materials, metal products, or resin pellets.
- Lower classes mean a lower cost-per-hundredweight (CWT), translating to significant savings for qualifying freight.
Impact:
If your freight meets the higher density thresholds, you could see notable cost reductions. Reviewing your packaging and stacking strategy can help you maximize these benefits.
3. Commodity Consolidation
The NMFTA is streamlining the system by consolidating or modernizing over 2,000 commodity descriptions. Many older listings will merge under broader categories, and outdated terminology will be eliminated.
- This simplification reduces confusion during classification.
- It will also make digital lookups more intuitive and efficient.
Impact:
With fewer ambiguities, there will be fewer disputes and re-class situations, saving time and preventing unexpected charges. However, your team must verify that any current NMFC item numbers in your system still apply after consolidation.
4. New Identifiers for Special Handling
Some freight has unique handling, stowability, or liability requirements, like hazardous materials, temperature-sensitive goods, or fragile items. The new NMFC introduces specific identifiers for these attributes.
- These flags will appear alongside classification details.
- They ensure carriers are aware of any special requirements at the quoting stage.
Impact:
This change improves transparency and reduces surprise accessorial charges. It also helps shippers and carriers communicate clearly about risks, improving compliance and safety in transit.
5. Digital Upgrade: ClassIT+
The NMFTA is rolling out ClassIT+, an upgraded version of its classification tool with better navigation, API integrations, and faster updates.
- Designed for both shippers and carriers, it allows quick classification checks.
- It will be the only platform updated with the new density scale and commodity descriptions.
Impact:
Shippers who rely on old systems or offline references risk misclassification and delays. Adopting ClassIT+ ensures accurate, real-time data, reducing the risk of disputes and making compliance easier.
What This Means for Shippers
Accuracy is Critical
Incorrect dimensions or weights will lead to misclassification and potential re-bills. Double-check:
- Dimensions (length, width, height)
- Stacking and pallet patterns
- Declared weight accuracy
Packaging Matters
Smarter packaging can improve density and potentially lower your freight class, resulting in cost savings.
System Updates Required
Update your TMS, WMS, and ERP before July 19. Old NMFC tables will cause tender rejections or misrated shipments.
Train Your Team
Educate your pricing, operations, and customer service teams on:
- New density rules
- Changes in rate impacts
- Handling flagged identifiers
Few Days Left: Your Action Plan
With the July 19 NMFC changes just days away, now is the time to act. Start by auditing your SKUs using ClassIT+ to confirm that each item aligns with the updated classifications. Next, test your rating systems to ensure your TMS and internal platforms reflect the new 13-tier density scale, this prevents rejected tenders and costly errors.
Make sure to communicate these updates internally, so your pricing, operations, and customer service teams are prepared for any adjustments. Finally, schedule a quick NMFC review with DIR Transportation. Our compliance-focused team can help you identify potential risks and avoid unnecessary re-class fees before the deadline.
