How Freight Class Is Worked Out

LTL carriers price by weight and class, and for most freight the class now follows density — how heavy the shipment is for the space it takes on the trailer:

Cubic feet = length × width × height in inches ÷ 1,728, for each handling unit including the pallet
Density = total weight in pounds ÷ total cubic feet
Class = the band on the NMFC density scale that the density falls in — 13 bands since NMFC Docket 2025-1 took effect on July 19, 2025

Some commodities keep a fixed class or have special handling provisions, so confirm the NMFC item before booking. We arrange FTL and LTL delivery across the US through vetted carrier partners — see ground transportation — and for port freight, transloading into domestic trailers.

Frequently Asked Questions

What is freight class?

A rating from the National Motor Freight Classification (NMFC) that LTL carriers use to price less-than-truckload shipments. Lower classes are dense, easy-to-handle freight and cost less per pound; higher classes are light, bulky freight and cost more.

How do I calculate freight density?

Measure each handling unit — pallet included — at its longest, widest and highest points in inches, multiply length × width × height and divide by 1,728 to get cubic feet. Divide the total weight in pounds by the total cubic feet. A 48 × 40 × 50 in pallet is 55.6 cubic feet; at 600 lb its density is about 10.8 lb per cubic foot.

What changed in the NMFC in 2025?

NMFC Docket 2025-1, effective July 19, 2025, adopted a standard 13-band density scale — from class 400 below 1 lb per cubic foot to class 50 at 50 lb or more — and moved many commodities from fixed classes to density-based classes. That is why many shippers now need to know their density.

Is the density class always the right class?

No. The NMFC item for your commodity decides the class; some items use the density scale and others have a fixed class or special handling provisions. Use the density result as a starting point and confirm the item. If the class on the bill of lading is wrong, the carrier can reweigh and reclassify the shipment and charge for it.
