The shipping costs for an air shipment are governed by the weight / volume rule.
The weight / volume equivalence rule is as follows: 1 tonne = 6 m3 (ie 1 m3 = 167 kg)
It is necessary to divide the volume by 6 to compare it to the weight and choose the most important to the advantage of the airline.
This means that the volume (in m3) is taken into account if it is six times the mass (in tonnes).
Example:
A shipment of 3 m3 for 300 kg, the tax will be based on 3 m3 x 167 kg or 501 kg
Actual weight: 300 kg <Taxable weight: 501 kg
