Understanding volumetric weight
Volumetric weight is a transportation price calculation method that may apply when your shipment is being transported by air.
In general, this method is only applied by express carriers such as Chronopost, UPS, FedEX, DHL or TNT which generally use this mode of transport.
When you use Boxtal, you don't have to consider the volumetric weight, because the prices you see incorporate this calculation method for the carriers that apply it.
Volumetric weight takes into account dimensions in addition to weight. So if your package is light but very bulky, you will pay more than if its size is small.
The most common formula is this:
Volumetric weight = (L x W x H) / 5000
with L (length), l (width), h (height) expressed in cm.
For example, if we take a package of 40 cm x 30 cm x 25 cm and 2 kg:
40 x 30 x 25 / 5000 = 6
Its volumetric weight is therefore 6 kg and is therefore superior to its actual weight of 2 kg. The billing applied will therefore relate to 6 kg.
In another example, if we take a package of 30 cm x 20 cm x 15 cm and 2 kg:
30 x 20 x 15 / 5000 = 1.8
Its volumetric weight is therefore 1.8 kg and is therefore lower than its actual weight of 2 kg. The billing applied will therefore relate to 2 kg.
