Shipping charges will be based on the dimensional weight of the shipment when the dimensional weight exceeds the actual weight.
Dimensional weight is determined by using KGB EXPRESS SERVICES volumetric standard.

How to Calculate Volumetric Weight :

To calculate the volumetric weight of your shipment ,simply multiply the length (cm) x hight (cm) xwidth (cm) and divide the result by 5000 .

You are sending a package the weight 8kg , but the dimensions are 40 cm x 30 cm x 50 cm.

If You're sending multiple packages calculate each weight separately and this is the 'Total Chargeable Weight' the chargeable weght is always the greater of the actual or volumetric weight .
