Determine Dimensional Weight
Dimensional weight reflects package density, which is the amount of space a package occupies in relation to its actual weight. Dimensional weight may apply to all international package services. For FedEx Cross Border shipments, dimensional weight is based on the density of a package when it arrives at a FedEx Cross Border Distribution Center.
Determine the package dimensions for each package that will be shipped to a FedEx Cross Border Distribution Center. Measure the length, width, and height of the package in inches at its longest points. Round each measurement to the nearest whole number (for example, 1.00 to 1.49 will be rounded down to 1, and 1.50 to 1.99 will be rounded up to 2). If the package has a bulge or is irregularly shaped, include in the measurements the bulge or irregular aspects of the package. Multiply the package length by width by height. The result is the package size in cubic inches. Finally, divide the cubic inches by 139 (international standard) to determine the dimensional weight.
Dimensional Weight = (L x W x H) / 139
Determine Billable Weight
International shipping rates are based on billable weight. Billable weight compares a package's actual weight to its dimensional weight*. The greater of the two is the billable weight and should be used to calculate the shipping rate.
*Note: Dimensional weight is based on the density of a package when it arrives at a FedEx Cross Border Distribution Center.
