What are the costs for shipping by air?
When it comes to air freight, weight and volume are key factors. Air carriers will charge by either volumetric weight (also known as dimensional weight) or actual weight, depending on which is more expensive.
The global rule of thumb is to calculate the volumetric weight is to multiply the item’s volume in cubic meters by 167. The volume is for a package that is W: 40cm, H: 40cm L:40 would have a .064 (the product of all sides divided by one million). Multiple by 167, and you get a volumetric weight of 10.67 kg.
If the volumetric weight exceeds the actual weight of the product, the volumetric weight becomes the chargeable weight. For light shipments, use this chargeable weight calculator to work out whether your shipment will be charged by actual weight or dimensional weight.
