The National Motor Freight Classification (NMFC) system, a critical framework for determining shipping rates in the Less-Than-Truckload (LTL) industry, is set for a significant overhaul in 2025. These changes, driven by the National Motor Freight Traffic Association (NMFTA) under its “Classification Reimagined” initiative, aim to modernize and streamline freight classification. Below, we explore the key updates, their impact, and how shippers and carriers can prepare.

Key Changes to the NMFC System

The 2025 NMFC updates, effective July 19, 2025, with Docket 2025-1, introduce several transformative changes:

  1. Shift to Density-Based Classifications
    The NMFC will transition from commodity-based to density-based classifications for most freight items. Density, calculated as weight per unit of volume, will become the primary factor for determining freight classes, reducing ambiguity and aligning classifications with actual shipping characteristics.
  2. Revised 13-Tier Density Scale
    The current 11-tier density scale will be replaced by a 13-subprovision scale, introducing new classes such as Class 50 and 55. This granular system aims to provide more precise classifications, enhancing consistency across shipments.
  3. Consolidation of Commodity Listings
    Approximately 2,000 commodity listings will be consolidated by combining similar commodities, reducing the total number of NMFC items. This simplification is expected to make the classification process more user-friendly.
  4. Special Handling Flags
    New flags will be introduced to identify freight requiring special handling, stowability considerations, or liability precautions. These flags ensure that unique shipping requirements are clearly communicated, improving operational efficiency.

Impact on Shippers and Carriers

The NMFC overhauls are designed to address the complexity and outdated nature of the current system, offering several benefits and challenges:

  • Simplified Classification Process
    By focusing on density and reducing the number of commodity listings, the changes aim to make classification more straightforward, reducing errors and improving predictability in billing and load planning.
  • Potential Rate Adjustments
    Shippers of heavier, more compact freight may benefit from lower rates due to the density-based focus. However, those shipping less dense items could face higher costs. Optimizing packaging to minimize voids will be critical to controlling expenses.
  • Compliance Requirements
    Accurate and updated shipping documentation is essential to avoid rate adjustments, additional fees, or shipping delays. Noncompliance with the new classifications could disrupt operations and increase costs.

Preparation Steps for Shippers and Carriers

To navigate the transition effectively, stakeholders should take the following steps:

  1. Audit Commodity Classifications
    Review current freight classifications to understand how they will be affected. Time Logistics Inc. is able to offer guidance based on density and historical data (LTL Expert).
  2. Optimize Data Management
    Use electronic Bills of Lading (eBOLs) and Transportation Management Systems (TMS) to ensure accurate documentation (eBOL Tools).
  3. Reconsider Workflow
    Incorporate tools like scales and freight dimensioners to measure density accurately. Contact logistics providers for vendor recommendations.
  4. Understand Rate Changes
    Work with carriers or 3PLs to negotiate rates and mitigate potential increases due to reclassifications.
  5. Optimize Packaging
    Minimize voids in packaging to achieve higher density and avoid higher freight classes.

Why These Changes Matter

The NMFC system has been criticized for its complexity and lack of transparency. The 2025 overhauls aim to create a more user-friendly, efficient, and transparent system by prioritizing density and introducing clearer guidelines for special handling. These changes are expected to enhance communication between shippers, carriers, and 3PLs, ultimately improving satisfaction and operational efficiency across the LTL shipping ecosystem.

Conclusion

The 2025 NMFC Classification Overhauls represent a significant step toward modernizing LTL freight classification. By preparing now—auditing classifications, optimizing packaging, and leveraging available tools—shippers and carriers can ensure a smooth transition and capitalize on the benefits of a simpler, more consistent system. Stay informed through NMFTA resources and engage with logistics partners to navigate these changes effectively.
