EMS Volumetric Weight
We got notice from China Post that there will be volumetric weight involved for big Chinese EMS parcels from December 10th, 2015. For big packages with the longest edge over 60cm, then there will be volumetric weight involved, and it's calculated as package length*width*hight/8000. The EMS fee will be based on the higher one between actual weight and volumetric weight. For parcels with longest edge less than 60cm, then EMS fee will based on actual weight, no volumetric weight involved.
Sorry for the inconvenience caused and we appreciate your kind understnding.
