Most of the international express delivery needs to be packed in neat and regular cartons, except for irregular and over-long cargo. The formula for calculating volumetric weight is length*width*height (cm)/5000, that is, 1CBM=200kg conversion. If the volumetric weight is greater than the actual weight, the freight must be calculated based on the volumetric weight.

One-ticket multi-piece billing rule: The actual weight and volume weight of all the pieces of a single ticket are added separately and then the sum of the two is compared. Whichever is larger will be used as the billing weight. UPS is more special. Compare the actual weight and volume of a single piece to a large value, round up to a unit of 0.5kg, and finally add up multiple pieces, and the final value is used as the billable weight of the ticket.
