Taking wool as net is a weighing method, and taking gross weight as net weight means taking wool as net weight. Net weight refers to the weight of the goods themselves, and gross weight refers to the weight of the goods plus the weight of the outer packaging. Gross net worth is usually used for low-value commodities, such as bulk agricultural products.

It means that the weight calculated by gross weight is the basis of pricing, and the weight and value of the package are no longer calculated separately. This method of calculating weight is generally used for agricultural products or other commodities with low value.
