Comparing Volumetric and Actual Weight.
It is recommended that you calculate the Volumetric Weight for every shipment that you send, then compare this to its actual weight. The greater weight of the two is used to work out the price that you are charged.
L x W x H (cubic inches) / Dim = Dimensional Weight
Take the Length 48″ and the Width of 40″ and take the Total Height example to the right would be 22″ of box plus 6″ of pallet to give you 28.” Example: 48″ x 40″ x 28″ = 53,760/ 194 = 277 lbs.
In most cases for domestic shipments the dim factor will be 194, but please check with provider to make sure this is the case. In most cases for International Shipments, the dim factor to use will be 166. Check with provider to make sure that you are using the correct dim factors.
Airfreight charges by the pound, based on the service requested, and it is based on the greater of actual weight or dimensional weight.
If a shipment weighs 500 lbs., and the Dim weight works out to 400 lbs., then the chargeable weight is the actual weight of 500 lbs. However, if the same shipment weighed 350 lbs., then the chargeable weight would be the 400 lb. dim weight!
