MOTOR-FREIGHT CLASSIFICATION
National Motor Freight Classification (NMFC)
The National Motor Freight Classification is NMFTA’s system for classifying commodities for relevant motor-freight rating. It evaluates transportability characteristics including density, handling, stowability and liability.
NATIONAL MOTOR FREIGHT CLASSIFICATION IN PRACTICE
- Describe the commodityUse accurate product and packaging information.
- Check the current ruleIdentify the applicable item and class basis.
- Validate the quoteReconcile dimensions, weight and service terms.
Use the agreed units, actual records and approved procedures for your operation.
A WORKED EXAMPLE
A density calculation needs the right commodity rule.
A shipper measures a pallet and calculates density. It still checks the applicable current NMFC item and other characteristics before assigning a class or accepting the resulting rate.
WHAT THIS MEANS FOR YOUR QUOTE
Agree the requirement before comparing quotes
Use the actual shipment, stock and service requirements. Record the billing unit, included work and responsibility for exceptions.
Put this term to work. Check the density calculation with our freight density calculator; use the applicable carrier classification and the guide to comparing 3PL quotes for the full cost comparison.
