Volumetric Weight
Volumetric weight is a calculated weight used by carriers to account for the space a shipment occupies. It is calculated from the external dimensions of the packaging ready for dispatch and a tariff-specific divisor. Charges are often based on the higher of actual weight and volumetric weight.
How is it calculated?
Volumetric weight in kg = length × width × height in cm ÷ divisor. For example, 40 × 30 × 30 cm gives a volumetric weight of 7.2 kg with an assumed divisor of 5,000. This divisor applies only if specified by the selected tariff.
What matters for thermal packaging?
- The complete outer packaging is measured. The internal usable volume is a different quantity.
- Rounding rules, surcharges and the treatment of pallets depend on the carrier and service.
- A smaller external volume can reduce freight costs, but must not compromise the required insulation, payload or temperature maintenance. A comparison must therefore consider cost and system performance together.
