LTL Freight Class Guide

What Freight Class Means

The National Motor Freight Classification, often called NMFC, groups commodities into freight classes. NMFTA describes freight class as being based on transportation characteristics including density, handling, stowability, and liability.

In everyday shipping language, the class tells an LTL carrier how difficult, dense, risky, or space-consuming the freight may be compared with other freight moving through the network.

Details To Gather Before You Quote

• Commodity description and NMFC item number, when available.
• Total weight, pallet count, and whether the freight is stackable.
• Length, width, and height for each pallet or handling unit.
• Packaging type, such as pallet, crate, carton, drum, or bundle.
• Pickup and delivery needs, including residential, liftgate, limited access, or appointment requirements.

Common Freight Class Mistakes

The most common problems are guessed classes, rounded-down dimensions, missing accessorials, and vague commodity descriptions. Those details can create a quote that looks good up front but does not match what the carrier sees at pickup or delivery.

If you are unsure about class, be conservative and gather better product details before booking. A few minutes up front is usually cheaper than a correction later.
