CHARGEABLE WEIGHT
The two main factors that affect the final cost of a shipment are the weight and the volume occupied. In the field of transport and logistics the parameter to be used to calculate the rates is the weight / volume ratio, different for each type of transport (air, sea, land). For example, in the field of road transportation the ratio of 1: 300 is considered as a reference, i.e. it is assumed that a cubic meter of goods weights 300 kg.
Transport rates are calculated based on the greater of the total weight or actual weight of the total volume (called also “taxable”) of all the packages part of a shipment. The taxable weight is calculated by multiplying the volume of the package with the weight-volume ratio considered by the type of transportation.
