Choose a class for its exact boundaries and worked examples. This 13-tier scale is effective July 19, 2025.
| Class | Density (lb/ft³) | Worked example focuses on |
|---|---|---|
| Class 50 | 50 and above | Class 50 has a lower density boundary and no next denser tier. |
| Class 55 | 35 to under 50 | Compact loads are sensitive to omitted base or packaging height. |
| Class 60 | 30 to under 35 | Changing a unit label must convert the measurement, not reinterpret it. |
| Class 65 | 22.5 to under 30 | A class 65 unit can disappear inside a misleading shipment average. |
| Class 70 | 15 to under 22.5 | A height change can move a class 70 load into class 85. |
| Class 85 | 12 to under 15 | A saved class from an older chart can disagree at 13.5 lb/ft³. |
| Class 92.5 | 10 to under 12 | The decimal in class 92.5 is a class label, not its density. |
| Class 100 | 8 to under 10 | Two identical pallets keep the same density when weight and volume both double. |
| Class 125 | 6 to under 8 | A displayed density close to 8 can still belong to class 125. |
| Class 175 | 4 to under 6 | A smaller package can improve density without crossing a class boundary. |
| Class 250 | 2 to under 4 | Do not subtract visible air gaps from a rectangular-envelope calculation. |
| Class 300 | 1 to under 2 | At 1.5 lb/ft³, a legacy chart and the current scale show different class labels. |
| Class 400 | Under 1 | The least-dense band still requires a positive measured gross weight. |
