NMFC Changes Are in Effect
Density-Based Classifications Reshape LTL Shipping in 2025

The NMFC changes we’ve been anticipating are finally here. The National Motor Freight Classification (NMFC) has shifted to a density-based system for most freight descriptions. This change by the National Motor Freight Traffic Association (NMFTA) simplifies classification, improves accuracy, and better reflects actual shipping costs for an overall enhanced user experience.
Key changes include:
Initially affecting 5,000 classifications, shippers can experience smoother operations and potential cost optimizations.
The new system streamlines freight classification using a standardized approach based on density, handling, stowability, and liability. This simplification makes it easier for shippers and carriers to understand and apply the classifications consistently.
Users will find the NMFC easier to navigate and understand with a more intuitive classification system. This improved clarity reduces confusion, minimizes errors, and allows for quicker, more confident decision-making in the shipping process.
The density-based approach aligns more closely with actual shipping costs and space utilization. This leads to more accurate classifications on the first attempt, reducing disputes, reclassifications, and administrative overhead for shippers and carriers.
