Gross

The term Gross usually describes the combined weight of a product and the container (a truck for example) that the product is being weighed in. If the product is not weighed in a container, the weight of the product alone is the Gross and the Net weight.

Tare

If a product is placed in a container when it is weighed, the term Tare (pronounced tear - as in 'tear in half') describes the weight of the container (a truck for example).

Net

Net weight is the amount of product being weighed excluding the container. In other words: Net = Gross - Tare. If the product is not weighed in a container (a truck for example), the weight of the product alone is the Net and the Gross weight.
