Volumetric Weight Calculation
When dimensional weight exceeds actual weight, shipments will be charged according to the IATA volumetric standard.
The factor for dimensional weight has changed as of January 3, 2011. Please see the new standard formulas below:
Chargeable Weight :
As per the regulations of the International Air Transport Association, air carriers charge either by weight or volume, whichever is greater. This is known as chargeable weight. Compare your shipments actual weight versus its volumetric weight and see which value is greater. If the dimensional weight is greater in value than the actual weight, transportation charges will be based on the dimensional weight value. We will always charge the greater of the two amounts.
