The National Motor Freight Classification (NMFC) is a standardized freight classification system used by LTL (Less-Than-Truckload) carriers across the United States. Developed and maintained by the National Motor Freight Traffic Association (NMFTA), the NMFC system assigns codes to commodities based on four key characteristics: density, handling, stowability, and liability.

Each NMFC code corresponds to a freight class ranging from Class 50 to Class 500. Lower classes (like Class 50) typically represent dense, easy-to-handle freight with lower shipping costs, while higher classes (like Class 500) indicate lighter, bulkier, or more fragile items that cost more to ship.

Finding the correct NMFC code for your shipment is simple:

1. Enter a keyword - Type the product name, description, or NMFC number in the search box above
2. Browse results - Review matching NMFC codes and their associated freight classes
3. Verify details - Check packaging requirements, density ranges, and any special notes

You can search by product name (e.g., "furniture", "electronics", "machinery") or directly by NMFC code number if you already know it. Our database contains over 10,000 NMFC codes covering virtually all commodities shipped via LTL freight.
