Freight Class Chart
Every class in the current NMFC density scale — the one in effect since July 19, 2025. Print it, pin it by the scale, and read any shipment's class straight off its density.
| Density (lb per ft³) | Class | Weight on a standard pallet (48 × 40 × 48 in) |
|---|---|---|
| under 1 | 400 | under 53.33 lb |
| 1–2 | 300 | 53.33 – <106.67 lb |
| 2–4 | 250 | 106.67 – <213.33 lb |
| 4–6 | 175 | 213.33 – <320 lb |
| 6–8 | 125 | 320 – <426.67 lb |
| 8–10 | 100 | 426.67 – <533.33 lb |
| 10–12 | 92.5 | 533.33 – <640 lb |
| 12–15 | 85 | 640 – <800 lb |
| 15–22.5 | 70 | 800 – <1,200 lb |
| 22.5–30 | 65 | 1,200 – <1,600 lb |
| 30–35 | 60 | 1,600 – <1,866.67 lb |
| 35–50 | 55 | 1,866.67 – <2,666.67 lb |
| 50 and up | 50 | 2,666.67 lb and up |
Pallet weights are rounded to two decimal places. Your class is decided by the unrounded density — the calculator always uses the exact figure.
How to read it: work out your freight's density (weight in pounds ÷ volume in cubic feet), find the row it falls in, and that's the density-based class. A density exactly on a line belongs to the denser band below it — 10.00 pcf is Class 92.5, not 100.
The pallet column is the same chart translated into weights for one standard 48 × 40 × 48 in pallet (53.33 ft³): if your loaded pallet weighs 640 lb, you're at the bottom edge of Class 85 territory.
Still seeing Class 500 somewhere? That class — like 77.5, 110, 150 and 200 — is no longer produced by density under the current scale. If a density chart or calculator gives you 500, its density table is out of date. Class 500 no longer comes out of the density scale (a specific NMFC item can still carry it).

The calculator works out volume, density and class for every piece of your shipment.
