Classification Resources

Everything you need to classify LTL freight clearly, consistently, and with confidence. Less-than-truckload (LTL) freight classification isn’t a one-off task—it’s a standardized system that keeps freight moving. This hub gathers the National Motor Freight Traffic Association, Inc.’s® (NMFTA)™ essential resources: rules, committees, research, training, and hands-on help so carriers, shippers, and logistics teams can get classification right the first time.
