Shipping companies use volumetric weight to ensure they are compensated for the space a package takes up, not just its weight. A large, lightweight package takes up as much space as a small, heavy one and limits the number of packages that can be transported.

To reduce your chargeable weight, you should try to use the smallest possible box that safely fits your item. Minimizing empty space by using the right-sized packaging will directly reduce the volumetric weight.

This feature is useful if you do not know the exact weight of your item. By selecting a material (e.g., wood, plastic, metal), the tool can provide an estimated actual weight based on the package’s dimensions, which can then be used for the chargeable weight calculation.

CBM stands for Cubic Meter. It is a standard unit of volume used in international freight to calculate the space a shipment will occupy.
