Net Weight (NW) is a basic measure of the weight of goods. What role does it play in transportation, and how important is it? This article explains net weight and its relationship to logistics.
What is net weight?
Net weight is the weight of the goods without their packaging. Manufacturers generally print this figure on the product's packaging.
For example, a snack package labeled with a net weight of 150 g contains 150 g of snacks. The total weight of the package and its contents is greater than 150 g.
What does net weight mean for transportation?
Net weight identifies the quantity of the product itself and can be a basis for pricing in commercial transactions. Goods are usually packaged for transport, often in additional crates, boxes, or cartons. Packaging can substantially change the shipment's total weight and dimensions.
Transport planning depends directly on the actual weight and size of the packed goods, including:
- Selecting a container based on the dimensions and weight of all packages.
- Selecting vehicles and handling equipment based on the shipment's total weight.
For cargo transportation, net weight alone therefore has a limited role in operational planning. It must still be declared in the relevant documents because it can affect product valuation and tax matters.

Net weight alone is not the basis for freight charges
Freight pricing considers shipment weight and dimensions. Packed shipment weight includes both the goods and their packaging. Using only net weight would leave the carrier uncompensated for the packaging weight. Therefore, Net Weight alone is not the charging basis discussed here forroad, sea or air transport.
The relationship between net, tare, and gross weight
Other relevant measures alongside net weight are gross weight and tare weight. Tare weight is the weight of the packaging, while gross weight combines the contents and packaging:
Gross weight = Net weight + Tare weight
These measures are closely related. For the transportation costs discussed in the article, packed gross weight is the relevant weight measure. To reduce it without changing the product's net weight, reduce tare weight by optimizing the packaging.
Tare weight can also refer to the unladen weight of a container or vehicle: the weight of the empty container or truck without cargo.
Net weight excludes packaging and cannot be reduced without changing the amount of product. For cost planning, the article therefore focuses on optimizing gross weight, particularly by reducing unnecessary packaging weight.
