NMFC Code Lookup

Search the National Motor Freight Classification (NMFC) database to find freight classes, article numbers, and commodity descriptions for LTL shipping.

What is NMFC?

The National Motor Freight Classification is a standard system used to categorize commodities for LTL (Less-Than-Truckload) freight shipping. Each item is assigned a freight class from 50 to 500 based on density, handling, stowability, and liability.

How Freight Classes Work

Freight class determines shipping rates. Lower classes (50-85) are denser, easier to handle, and cheaper to ship. Higher classes (150-500) are lighter, bulkier, or more fragile and cost more. Density is the primary factor.

Understanding NMFC Freight Classification

The National Motor Freight Classification (NMFC) system, maintained by the National Motor Freight Traffic Association (NMFTA), assigns freight classes to over 10,000 commodity types. Each NMFC article describes a specific type of goods and its associated freight class, which ranges from Class 50 (most dense, lowest cost) to Class 500 (least dense, highest cost).

Freight classification is determined by four characteristics: density (weight per cubic foot), handling (ease of handling and special requirements), stowability (how well items can be stowed with other freight), and liability (susceptibility to damage or theft).
