Volumetric weight is a technique for pricing transport services, incl. courier and postal services, using an approximate weight calculated on the basis of the length, width and height of a package. The need for this method of calculation is that light and low-density packages become unprofitable for hauliers due to the amount of space they occupy in the truck (aircraft / ship) in proportion to their actual weight.
The concept of weight dimensions has been adopted by the transport industry around the world as a single means of establishing a minimum charge for the cubic space occupied by a package.
The volumetric weight is calculated by the following formula:
Volumetric weight (kg) = Height (cm) x Length (cm) x Width (cm) / 6000.
It is rounded up to a whole kilogram. If a difference is found with the declared weight, the control weight is considered correct. Shipments are charged at the higher value between the actual or volumetric weight.
