Depending on how much room they take up inside the airplane, it is occasionally feasible to ship big objects with a low total weight. In these situations, the shipping cost is determined using volumetric weight, sometimes referred to as dimensional weight. Every package you send should have its volumetric weight determined and compared to its actual weight. The fee we charge you is based on the bigger of the two weights. The formula for calculating international volumetric weights is (Length x Width x Height in centimeters) / 5000 = Volumetric Weight in kilograms.
