What is freight class 175?

Freight class 175 is the NMFC rating for freight with a density of 4 - 6 pounds per cubic foot under the current density scale (Docket 2025-1, effective July 2025). Typical examples: assembled furniture, garments on hangers.

What density is class 175?

Class 175 covers 4 - 6 lb per cubic foot. Bands are inclusive at the lower edge and exclusive at the upper edge.

Is class 175 expensive to ship?

Lower classes are cheaper per pound. Class 175 is position 10 of 13 on the current scale, so it prices toward the expensive, light end of LTL freight.

Freight Class 175: Density Range, Typical Freight & Cost Position

What ships at class 175

Class 175 covers 4 - 6 pcf, the classic band for assembled furniture and garments on hangers. Density is punishing here: a sofa that ships assembled at 4.5 pcf rates 175, while the same sofa flat-packed at 9 pcf rates class 100 - a materially cheaper move for identical goods.

Worked example. A standard pallet: 48 × 40 × 48 in, 265 lb. That is 53.3 cu ft and 265 lb → 4.97 pcf → class 175. Run your own numbers →

Band edges are inclusive at the bottom, exclusive at the top: exactly 4 pcf is class 175, but just below it the class gets more expensive — 3.99 pcf rates class 250. A few pounds of packaging or an inch of pallet height can move a borderline shipment across that line.

Where class 175 sits on the scale

Freight class runs from 50 (densest, cheapest per pound) to 400 on the current density scale. Class 175 is band 10 of 13.

Either side of this band: denser freight (6 - 8 pcf) rates class 125, which is cheaper; lighter freight (2 - 4 pcf) rates class 250, 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.
