The National Motor Freight Classification (NMFC) system, which has provided a standardized method of identifying and classifying freight for over 70 years, is undergoing its most significant overhaul in decades. Keith Peterson, director of operations at the National Motor Freight Traffic Association (NMFTA), joined the Talking Supply Chain podcast to explain the rationale and impact of these changes, which officially take effect on July 19, 2025. The revised system emphasizes density-based classification, streamlining the number of commodity codes and modernizing how freight is categorized for today’s shipping environment.
