Package density is one of the factors that affects the shipping rate. The volumetric weight of a package is an index reflecting the package's density. A less dense package generally occupies more space, in comparison to its actual weight. Thus, the shipping rate is determined according to the actual weight or the volumetric weight, whichever is greater.
According to industry practice, the proper formula used to calculate volumetric weight (in lb) is:
Length (inch) x Width (inch) x Height (inch) ÷ 166 (DIM weight factor)
(Please note that the calculation varies amongst different countries and regional market practices.Standard Express and Economy Express adjust volumetric weight divisor from 166 to 139)
