12 - 15 pcf · NMFC density scale

Freight class 85

The rating for freight at 12 - 15 pounds per cubic foot on the current 13-band NMFC density scale. Typically crated machinery, boxed hardware.

What ships at class 85

Class 85 spans 12 - 15 pcf, typical of crated machinery and boxed hardware. Note the boundary behaviour: 12.00 pcf is class 85, while 15.00 pcf is class 70, not 85 - bands are inclusive at the bottom, exclusive at the top. Freight around 13.5 pcf rates class 77.5 on the obsolete density guideline some free calculators still run; no band of the current scale produces that number.

Worked example. A standard pallet: 48 × 40 × 48 in, 700 lb. That is 53.3 cu ft and 700 lb → 13.12 pcf → class 85. Run your own numbers →

Band edges are inclusive at the bottom, exclusive at the top: exactly 12 pcf is class 85, but just below it the class gets more expensive — 11.99 pcf rates class 92.5. A few pounds of packaging or an inch of pallet height can move a borderline shipment across that line.

Where class 85 sits on the scale

Freight class runs from 50 (densest, cheapest per pound) to 400 on the current density scale. Class 85 is band 6 of 13.

Either side of this band: denser freight (15 - 22.5 pcf) rates class 70, which is cheaper; lighter freight (10 - 12 pcf) rates class 92.5, which costs more.

The full table is on the freight class chart, and the calculator works out density and class from your dimensions, including multi-pallet shipments.

Density is the default, not the whole rule. Since Docket 2025-1 most commodities class by density, but items with unusual stowability, handling or liability characteristics can class differently. Confirm the NMFC item before the BOL goes out.
