Prices (air freight rates) are always quoted per kg or 6dm³.  This may also be called a volume ratio of 1:6 or 1m³ = 167kg.  This means you pay either for the weight or for the space require to transport your consignment.

Whether you pay for the weight or the space it is determined using the following formula :

Example 1

You send 1 case weighing 80 kg with dimensions of 50 x 50 x 50 cm

You multiply: 50 x 50 x 50 cm = 125 000 cm³

You divide: 125 000 cm³ / 6000 = 20.83 kg volume weight.

Here the actual weight (80 kg) is higher than the volume weight (20.83 kg), so 80 kg will be charged as the billable weight.

Example 2

You send 8 boxes with a total weight of 45 kg.

All boxes are of equal size (60 x 40 x 20 cm per box).

You multiply: 8 boxes x 60 x 40 x 20 cm = 384 000 cm³.

You divide: 384 000 cm³ / 6000 = 64 kg volume weight.

Here the volume weight is greater than the actual weight, so 64 kg will be charged as the billable weight.
