Nettopaino

Nettopaino, or net weight in English, is the weight of the product itself excluding any packaging or container. It is the amount of product that a package contains and is the quantity typically declared on prepacked goods. Nettopaino is contrasted with bruttopaino (gross weight), which includes the weight of packaging, and with tare weight, the weight of the packaging that is not part of the product itself.

Netto weight can be determined by weighing the contents after removing packaging, or by subtracting the tare weight of the container from the total gross package weight. In practice, many manufacturers or retailers specify the net weight on the label, so consumers know exactly how much product they are purchasing.

The unit of net weight is usually the same as the unit used for selling the product. In metric systems, this is typically grams or kilograms; for liquids, volume may be indicated, but the term net weight often still refers to mass. Labeling standards typically require the net weight to be accurate and easy to read, and the presentation is designed to allow straightforward comparison between products.

Regulatory frameworks in many jurisdictions require net weight to be declared for prepackaged goods. Accurate net weight supports fair trade, consistent pricing, and reliable inventory and shipping calculations. Discrepancies between stated net weight and actual contents can lead to penalties or recalls.
