Measure the handling unit as it ships — palletized freight includes the pallet's dimensions and weight. Density-based estimate; the NMFC commodity listing (handling, stowability, liability) can override it.

Is density the only factor?

No — density sets the baseline since NMFTA's 2025 changes, but commodities with special handling, stowability or liability characteristics keep their own NMFC listings. Confirm with the NMFC or your carrier before booking.
