When shipping to Hawaii or Guam, ocean delivery, wharfage and terminal handling charges are based on density or actual cubic feet, whichever is greater.
In order to compute actual cubic feet, you will need to measure the length, width and height (in inches) of each piece to be shipped. One cubic foot is equal to a single piece with the dimensions of 12" x 12" x 12". To compute cubic feet, first multiply together all the dimensions for the piece being measured. Then divide the total by 1728. This calculation will give you your total amount of cubic feet for the piece. Total the individual pieces "cubed" to determine your total shipment cube.
- 12" X 12" X 12" = 1728
- 1728 / 1728 = 1 cubic foot or 12" X 12" X 12" = 1 cubic foot
Some helpful hints in computing cubic feet:
- When taking your dimensions, round up to the next highest inch. Example: 11 ½" =
- Total cubic feet should always be rounded up. Example: 10.45 cubic feet = 11 cubic
- With multiple pieces of the same dimensions, multiply the total number of pieces
along with the dimension. For example, 10 pieces at 12 x 12 x12 would be computed
as follows: 10 PCs X 12" X 12" X 12" = 17280 / 1728 = 10 cubic feet
When cubing a shrink-wrapped pallet, measure the highest, widest and longest dimension of the pallet. If the product does not take up the full amount of space on the pallet, you must still measure the width and length of the pallet itself, as well as the highest point of the product on the pallet. This is because your pallet is using the space within the container. Should the product hang over the edge of the pallet, you will need to measure the length and width of the product stacked on the pallet as the largest dimensions.
When computing cubic feet on shipments that consist of multiple pieces having different
dimensions, compute the amount of cubic feet for each piece and then add up the
cubic feet for all the pieces to determine the total cubic feet for the shipment.
You do not need to round up the cube for the individual pieces. Round up the cubic
feet total of all the pieces added together.
To compute density cubic feet, divide the weight of shipment by 45 to ensure that
the 45 lb. density rule cube does not exceed the actual cube. If it exceeds the
actual cubic feet, you will be charged based on density.
The formulas used to convert weight and cube into metric for international shipment
pricing are as follows:
- International “less than container-load” (LCL) rates are quoted on a weight/measurements
(w/m) – revenue ton basis. A revenue ton is defined as 1 cbm (m3) and/or 1000 kg.
The basis for the calculation is whatever yields the greater revenue.
- To calculate the cubic meters:
- Follow steps above to get cubic feet
- Divide cubic feet by 35.314 to determine cubic meters
- To determine weight in kilos divide gross weight by 2.2046. Every 1000 kilos is
considered a one CBM. The higher of actual measurement of the cargo or 1 CBM for
each thousand kilos is used to determine the CBM for billing purposes.
