What is NMFC?
NMFC (National Motor Freight Classification) is a standardized freight classification system published by the National Motor Freight Traffic Association (NMFTA). It provides a consistent way to categorize commodities shipped via LTL, assigning each a class based on transportability characteristics.
NMFC Codes
Each commodity in the NMFC has a unique code (NMFC number) and an assigned freight class. For example:
- NMFC 100310: Machinery, iron or steel
- NMFC 116030: Furniture, wooden
- NMFC 86720: Plastic articles
Classification Factors
- Density: Weight per cubic foot
- Stowability: How well it fits with other freight
- Handling: Special requirements or equipment needed
- Liability: Susceptibility to damage, theft, or spoilage
