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 lb |
| 1–2 | 300 | 53–107 lb |
| 2–4 | 250 | 107–213 lb |
| 4–6 | 175 | 213–320 lb |
| 6–8 | 125 | 320–427 lb |
| 8–10 | 100 | 427–533 lb |
| 10–12 | 92.5 | 533–640 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 | 1,600–1,867 lb |
| 35–50 | 55 | 1,867–2,667 lb |
| 50 and up | 50 | 2,667 lb and up |
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. A chart or calculator that gives you 500 is using the pre-2025 table.
