Freight Class 300 — Density Range, Examples & Calculator

Freight class

300

Density range

2–3 lb/ft³

Class 300 covers freight with a density of 2–3 lb/ft³. Typical examples: assembled wood furniture, chairs, model boats, wicker products. Higher classes cost more per pound because light, bulky freight consumes trailer space and damages more easily.

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.
