Measure the packed cargo Give the length, width and height of each package type, including pallets and protruding parts. Always state the units. Distinguish net and gross weight Transport quotations need the weight including packaging. If you only know the goods’ net weight, make that clear. Volume For a rectangular package, volume is length × width × height in metres. Multiply by the count for several identical packages. Chargeable weight Some transport services consider volumetric as well as actual weight. Ask for the applicable factor and calculation rule; there is no universal factor for all freight services.
