Understand your freight before you request a quote.

How Rate Farm evaluates your shipment

A freight class estimate starts with density — a shipment's weight divided by the space it occupies. Density alone doesn't tell the whole story, though: NMFC classification also weighs handling, stowability, and liability, and different handling units within the same shipment can genuinely land in different classes. (See how freight density is calculated for the full breakdown.)

That distinction matters more than it might seem. Blending several pallets into one shipment-wide average density can make a shipment look like it belongs in a single class when it doesn't — a small, dense pallet and a large, light one rarely share a real classification, even though their combined average might suggest otherwise. Rate Farm calculates each handling unit's density and estimated class individually, then flags the shipment as mixed when they differ, rather than presenting one averaged number as though it were the answer.

The result above is Rate Farm's estimate, not a final NMFC determination. Carriers can reweigh, remeasure, and reclassify freight after pickup based on the commodity's actual characteristics. Preparing accurate dimensions, weight, and shipment details before you request a quote is the most reliable way to reduce that risk — which is what the Builder and Shipment Brief are for.
