The standardized freight-class catalog used by LTL carriers in North America to price every shipment by density, stowability, handling, and liability.
## What is the NMFC? The **National Motor Freight Classification** is a publication of the National Motor Freight Traffic Association (NMFTA) that assigns every commodity an **NMFC item number** and one of 18 **freight classes** (50, 55, 60, 65, 70, 77.5, 85, 92.5, 100, 110, 125, 150, 175, 200, 250, 300, 400, 500). ## Why scrap operators care - Outbound loads to mills travel under an NMFC class. - Wrong class = re-class charge from the carrier. - Scrap-metal classes commonly used: **NMFC 102240** (iron or steel scrap), various subitems. ## How WeighPay handles NMFC WeighPay's BOL/BOL-eMERGE printout includes NMFC item number and class automatically based on the load's material code.
