Freight class 100
Two identical pallets keep the same density when weight and volume both double.
8 to under 10 lb/ft³
The lower boundary of 8 lb/ft³ is included. Exactly 10 lb/ft³ enters class 92.5.

Where this class 100 example sits
Toward class 125: 9.375 − 8 = 1.375 lb/ft³ above the cutoff. The lower edge remains included. Toward class 92.5: 10 − 9.375 = 0.625 lb/ft³ to the next boundary.
Two identical 500 lb handling units
Each finished unit measures 48 × 40 × 48 in and weighs 500 lb. Two units total 1,000 lb and about 106.667 ft³. Their combined density is 9.375 lb/ft³, the same as one unit, so the density estimate remains class 100.
Quantity multiplies both weight and volume. In the calculator, enter 500 lb as weight per piece and 2 as quantity. Entering the 1,000 lb shipment total as weight per piece would count the shipment weight twice and incorrectly increase the estimated density.
| Scenario | Quantity × L × W × H; weight per unit | Total volume | Density | Class |
|---|---|---|---|---|
| One 500 lb unit | 1 × 48 × 40 × 48 in at 500 lb each | 53.333 ft³ | 9.375 lb/ft³ | 100 |
| Two identical units | 2 × 48 × 40 × 48 in at 500 lb each | 106.667 ft³ | 9.375 lb/ft³ | 100 |
| Two units, each 45 in high | 2 × 48 × 40 × 45 in at 500 lb each | 100 ft³ | 10 lb/ft³ | 92.5 |

Compare the measured scenarios
Unrounded density; rounded display labels.
Keep total weight separate from weight per piece
For two unchanged 500 lb weights, reaching 10 lb/ft³ requires a combined volume of 100 ft³. That is 6.25% below the original 106.667 ft³. At the same footprint, 45 in total height per unit reaches that boundary exactly.
The shorter configuration is only a calculation scenario. Use the dimensions your completed packaging actually has; do not enter a target height before the shipment is safely packed and remeasured.
Reduce both identical units to 45 inches
One 500 lb unit then occupies 50 ft³. Two occupy 100 ft³ at 1,000 lb; both the individual and combined estimates reach class 92.5 without a quantity error.
| Boundary density | Target volume | Total height | Class at boundary |
|---|---|---|---|
| 10 lb/ft³ | 50 ft³ | 45 in | 92.5 |
Arithmetic target; confirm safe packaging.
Questions before you ship
Is exactly 10 lb/ft³ class 100?
No. Class 100 includes 8 and excludes 10 lb/ft³. Exactly 10 belongs to class 92.5 on this scale. The two-unit example at 45 inches high reaches that boundary.
