We follow the international standard to determine the volume metric weight of a shipment. All international shipping carriers base their shipping rates on the volume weight, which is the greater of Actual weight and Dimensional weight. Actual Weight is the weight of the package when put on a scale. Dimensional Weight is based on the size of the package. Large items that have a small Actual Weight, like pillows and lamp shades, will have a larger Dimensional Weight. In most cases we make all attempts to repackage items to avoid volume metric charges.
