NMFC Lookup
Look up NMFC codes and freight classes by commodity. The National Motor Freight Classification assigns every shipped commodity an article number and a freight class (50-500) that determines LTL rates.
No NMFC articles matched auto parts. Try a broader commodity term, or browse the popular searches above.

What is NMFC?
A standardized system by the NMFTA that classifies LTL freight into 18 classes based on density, stowability, handling, and liability.
Why freight class matters
Carriers price LTL shipments by class. The right NMFC code prevents reclassification fees and billing disputes.
