Our Air freight customers usually go mad when they are charged by volume as against the dead weight of an item. Unfortunately most freight forwarders cannot help with this and why is this? This is because the airline will charge the dead weight or volume weight , whichever is higher.
Take for instance , you have a little van that makes a journey of 20 miles and fits 40 boxes weighing 300kg in total, then you have a van that makes the same journey with 20 boxes that filled the van and weighing 150kg. Assume your billing is in kg and billed at £1/kg x 300kg, you will be looking at £300 for the trip and the other van will be looking at £150 for the same trip. If the cost of running the service will cost about £200 to execute and the profit is £100 at 300kg, then obviously the other van with £150 bill wont be able to make the trip or would be at serious loss. This system also applies to airline billing .
The airline will calculate the length as L X W x H / 6000 = Volumetric weight. Let us examine the following ;
