While the NMFC system can be complex, the upcoming changes are intended to simplify the classification of LTL freight.
On July 19, 2025, changes will be implemented to the National Motor Freight Classification (NMFC), marking one of the most significant updates in years. Being informed and preparing in advance can help ensure a smoother transition.
While the NMFC system can be complex, the upcoming changes are intended to simplify the classification of LTL (Less-Than-Truckload) freight. The National Motor Freight Traffic Association (NMFTA) has been working for several years on the initiative known as Classification Reimagined, aimed at responding to the ongoing evolution of LTL freight transportation, driven by changing products, technological advancements, and the adoption of new industry methods. The ultimate goal is to enhance the overall experience for users of NMFC and ClassIT.
What are the NMFC changes?
The new classification will simplify how LTL freight rates are determined by using a standardized density scale for freight that does not present issues related to stowability, handling, or liability. What does this mean? It means that goods with similar density values can be classified the same way, regardless of the type of item.
The main classification changes include:
1. Density-Based Classification: Density will become the primary factor in determining freight class for more than 2,000 commodities, replacing the previous system focused on commodity type. To improve accuracy, the current 11-class density scale will be expanded to a 13-class scale.
2. Commodity Listings: Specific item categories will be expanded. While this is expected to simplify the process, it may also require updates to current classifications.
3. Special Handling Identifiers: Shipments that require special handling will be assigned unique identifiers based on their specific handling needs and associated risks.
4. Launch of ClassIT+: ClassIT+ is NMFTA’s enhanced classification tool with improved integration capabilities. It is designed to help LTL shippers more easily identify and apply the correct classifications.
According to NMFTA, these changes will impact both shipping costs and operational processes. With the new density-based classification, if freight is packaged more densely, the shipper may benefit from a lower class and potentially reduced rates. Conversely, if the freight is over-packaged, making it lighter and more voluminous, it may be assigned a higher class and face increased rates.
How to Prepare for the NMFC Changes
Although the new classification system is intended to streamline processes, fleets still need to familiarize themselves with the changes. To help with this transition, here are some tips based on a recent article by ArcBest, a logistics and freight transportation company:
- Review your current classifications: Compare your existing NMFC codes to identify changes under the new system.
- Know your freight’s exact dimensions: Density-based pricing requires accurate data. Be sure to properly record your shipment’s measurements.
- Update your TMS and shipping systems: If your NMFC codes are integrated into a TMS, WMS, ERP, or other shipping technologies, review and update the classifications as needed.
- Train your team: Ensure your staff understands how to calculate density and apply the new classification guidelines correctly.
