As per freight industry practice, the chargeable weight of a package is calculated based on Volumetric or Actual weight, whichever is higher.
Volumetric weight of a package is a calculation that reveals the density of a package and we use the below formula to derive the volumetric weight of a package
Volumetric weight = [ length(cm) x breadth(cm) x height(cm) ] / 5,000cm You can advise your merchant to ensure proper packaging or pack your purchase into a smallest possible box.
In addition, you can consolidate your shipping charges by paying multiple packages together. As such, only one single base charge is billed.
