What is freight class 100?

Freight class 100 is the NMFC rating for freight with a density of 8 - 10 pounds per cubic foot under the current density scale (Docket 2025-1, effective July 2025). Typical examples: cabinets, wine cases, packaged tools.

What density is class 100?

Class 100 covers 8 - 10 lb per cubic foot. Bands are inclusive at the lower edge and exclusive at the upper edge.

Is class 100 expensive to ship?

Lower classes are cheaper per pound. Class 100 is position 8 of 13 on the current scale, so it prices mid-scale of LTL freight.

Freight Class 100: Density Range, Typical Freight & Cost Position

What ships at class 100

Class 100 covers 8 - 10 pcf and marks the point where freight starts being priced more for its volume than its weight. Cabinets, wine cases and packaged tools are typical. Freight around 8 - 9 pcf comes out as class 110 on the obsolete guideline still hard-coded into several free calculators; on the current scale that density is class 100.

Worked example. A standard pallet: 48 × 40 × 48 in, 480 lb. That is 53.3 cu ft and 480 lb → 9.00 pcf → class 100. Open this example in the calculator →

Where the edges are. On that same 48 × 40 × 48 in pallet (53.3 cu ft), class 100 covers every weight from 427 lb up to 533 lb; at 534 lb it rates class 92.5 and at 426 lb it rates class 125. Enter your own shipment in the calculator and it tells you how far you are from either edge.

Band edges are inclusive at the bottom, exclusive at the top: exactly 8 pcf is class 100, but just below it the class gets more expensive — 7.99 pcf rates class 125. A few pounds of packaging or an inch of pallet height can move a borderline shipment across that line.

Commodities that commonly rate class 100

Freight quoted in this band, with the density logic and a worked example for each: appliances · computers · electronics · furniture · motorcycles · paper · refrigerators · tools · toys.

Freight in this band is also where an out-of-date calculator hands you class 110. That number is not on the current density scale, so seeing one back from a density calculation means the tool is reading an older guideline.

Where class 100 sits on the scale

Freight class runs from 50 (densest, cheapest per pound) to 400 on the current density scale. Class 100 is band 8 of 13.

Either side of this band: denser freight (10 - 12 pcf) rates class 92.5, which is cheaper; lighter freight (6 - 8 pcf) rates class 125, 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.
