International Shipping Formula
Lightweight bulky packages are "weighed" by their dimensions in order to take size into account. Dimensional weight, also called "dim" weight, is used because the space a package takes on an aircraft may cost more than the package's weight. You should calculate dimensional weight on every shipment, compare that to its actual weight and use the greater of those two to determine your shipping cost. International and domestic weight are calculated differently. Refer to formula.
Please use a commercial invoice. If one is not available, please obtain one here.
