2025 NMFC Changes Decoded: Freight Class Simplified for Shippers

Navigating the 2025 NMFC Overhaul

Hold on tight. Significant changes to the National Motor Freight Classification (NMFC) system are set to take effect on July 19, 2025. These updates, introduced by the National Motor Freight Traffic Association (NMFTA), aim to simplify freight classification, enhance accuracy, and align with modern shipping practices. While the intent is to simplify the process, we can admit that trying to decipher the changes and understand how this impacts you feels complex, to say the least. 

Multiple documents spanning around 800 pages were recently presented outlining each change. Now, you can go through all 800 pages and interpret the changes yourself, if you’d like. Or, you can lean on the expertise of our analytics and operations teams who have done the difficult work for you and translate it all into a much more digestible format. Your choice!

For shippers, carriers, and 3PLs, understanding these changes is crucial to avoid unexpected charges and ensure smooth operations.

Key Changes in the 2025 NMFC Update

Transition to a Standardized Density-Based Classification

Why it matters:
The move from a commodity-based system to a 13-tier density-based classification is arguably the most significant change in decades. Until now, freight classes were determined by a combination of commodity type, density, stowability, handling, and liability. That many variables oftentime created inconsistencies, confusion, and, often, disputes.

Why the change was made:
This shift aims to simplify pricing and increase fairness. Density is a more objective metric that reflects the actual space a shipment occupies in a trailer. As carriers grapple with rising equipment and labor costs, they need more accurate data to maximize trailer utilization and avoid wasted space. This model encourages shippers to measure accurately and package efficiently.

Consolidation of Commodity Listings

Why it matters:
The NMFTA will consolidate approximately 2,000 commodity listings, eliminating overlaps and modernizing outdated product descriptions that no longer reflect how goods are shipped. 

Why the change was made:
The old system had grown overly complex, with similar items scattered across multiple classifications. This added friction and confusion during the quoting and billing process. The updated system is designed to be simpler, faster, and more intuitive, especially for businesses shipping a wide range of goods. For example, in the pst, there were several classifications for “furniture” based on what material was used, like wood, metal, or fabric. But, in many cases, furniture is created with all of those materials. Classifications like this one were changed to be a bit broader and easier to understand. 

Introduction of Unique Identifiers for Special Freight

Why it matters:
Not all freight is created equal. Some items pose liability risks, require unusual handling (like glass panels or hazardous materials), or can’t be loaded alongside other goods. The new unique identifiers help flag this freight at the point of classification.

Why the change was made:
Previously, these extra considerations were often handled inconsistently, leading to billing disputes, damaged freight, or poor trailer optimization. By assigning standardized identifiers for these variables, all parties involved are on the same page from the start and know exactly what they’re shipping and how to handle it. 

Implications for Shippers

These changes will impact how freight is classified, rated, and billed. If you don’t adapt, the ripple effects could hit fast. Here’s how:

• Unexpected Charges: Incorrect classifications may result in additional fees, reclassification charges, or adjusted invoices.
  
  
• Operational Delays: Misclassified freight can cause shipment delays due to inspections or adjustments at a terminal if a carrier notices a discrepancy in the classification and the actual freight. With such narrow windows for delivery and on-time compliance requirements only getting stricter, this may have a significant impact on your operations.
  
  

How to Prepare for the 2025 NMFC Changes

The last thing you want is to get caught scrambling right before July 19th to figure out how these 2025 NMFC changes will impact you. Get ahead of the updates and begin taking stock of your freight. To prepare for the upcoming changes consider the following:

1. Review Current Classifications: Audit your existing freight classifications to ensure they align with the new density-based system. Or, ask your trusted carrier partner to review your classifications for you.
   
   
2. Utilize the NMFC Item Lookup Tool: This free and incredibly helpful tool provided directly by the NMFC allows you to check if your freight items are affected by the 2025 updates. Access it here.
   
   
3. Update Internal Systems: The NMFTA recommends you ensure your Transportation Management System (TMS), Warehouse Management System (WMS), and other relevant platforms are updated to reflect the new classifications prior to the July 19th deadline. 

4. Train Your Team: Now is the time to ensure every possible stakeholder on your team is aware of these changes. Operations, warehouse, traffic, and logistics teams must all be aware of the new classifications and how your freight may change.
   
   
5. Communicate with Partners: Inform carriers and 3PLs about your updated classifications to maintain alignment and avoid disputes. Your carrier should be aware of all details and data reflecting your freight. They’re your trusted partner in ensuring your supply chain runs smoothly. If your carrier partner hasn’t already reached out to you on this topic, it may be time to consider a more reliable and proactive partner, like National Consolidation Service.
