Find the class before the carrier does
Density decides freight class for most general freight. Enter the handling unit and this returns the band, the full scale, and — the useful part — how far you are from the next break in either direction.

Handling unit
Per unit, not per orderWorth knowing
Density decides class for most general freight, but a published NMFC item for the commodity can override it on stowability, handling, or liability grounds. This tool does not return an authoritative NMFC item code.
Check the class your carrier actually files against before pricing a lane on it.
Freight class

Density

lb / ft³
Typically: car parts, food in cases.
Next break
You are 4.5 lb/ft³ short of class 65. Adding 300 lb on the same footprint — or shipping the same weight in less air — moves you into the cheaper band. You have 200 lb of headroom before dropping to class 77.5, which costs more.
