International Courier Volumetric Weight vs Actual Weight Charges Explained
Mouli
Air Freight & Courier Operations Lead
When shipping parcels internationally, express airlines evaluate shipping charges based on billing weight, which is defined as the GREATER of Actual Weight vs. Volumetric (Dimensional) Weight.
The Standard Volumetric Weight Formula
For air cargo, volumetric weight is computed as: (Length in cm × Width in cm × Height in cm) ÷ 5000 = Volumetric Weight in Kilograms.
For example, if you ship a box weighing 3 kg physically, but measuring 40 cm x 40 cm x 30 cm, its volumetric weight is (40×40×30)/5000 = 9.6 kg. In this case, airlines charge for 10 kg billing weight because volume occupies aircraft cargo space.
Tips to Minimize Volumetric Charges
- Use vacuum sealing bags for clothes, winter jackets, and blankets to reduce volume by up to 70%.
- Choose tight-fitting corrugated boxes without excess empty cushioning space.
- Consolidate multiple small items into a single dense box rather than multiple loose boxes.
