Weight & Shipping Cost
The courier compares two different types of weight and decide shipping Cost accordingly.
2 Types of Weight
The first is ( called ) the actual, gross, or total physical weight of your shipment, including any packaging and pallets. It is simply the entire shipment weight, typically expressed in kilograms (kgs).
The second type of weight is the volumetric or dimensional weight (the volume of your cargo). It is also expressed in kilograms but based on your shipment’s dimensions (length, width and height in centimetres), to which a density ratio ( usually it is 5000 or 6000 ) is applied. *Do not forget to include all the packages.
The reason why there has volumetric weight is because the cost of transporting a shipment can be affected by the amount of space that it occupies on an aircraft, rather than the Gross Weight. The volumetric weight of a shipment is a calculation that reflects the density of a package. A less dense item generally occupies more volume of space, in comparison to its Gross Weight.
How shipping price is decided?
Remember the carrier’s choice and the phrase “whichever is greater,” comparing actual weight and volumetric weight and basing the charge on the higher figure.
For example： If your cargo contains large machinery parts, it will be heavy but dense. The Gross weight will probably be greater than the volumetric weight. And if your cargo contains individual plastic components within protective polystyrene packaging, it will be light but take up a relatively large amount of space. The volumetric weight may be greater than the Gross Weight.
Another example is as what it shows in the picture.
The gross weight of a pair of shoes (including shoe box packaging) is 0.5KG, while the volumetric weight is 1.8KG. At this time, when calculating the freight, 1.8 kg should be selected. If you buy N pairs of shoes, then you should compare N x Gross weight and N x Volumetric Weight
