Frequently Asked Questions

“Multi-unit package” means a package containing two or more individually packaged or labelled units of the same food commodity of identical and/or different, net quantity intended and displayed for retail sale either in individual units or package as a whole and complies with the general labelling requirement.

On the other hand, the wholesale package also means individually packaged units of the same food commodity, however, intended to be distributed to an intermediary and not for direct sale to a single consumer. 

  • What is the difference between Net weight and Drained weight?

On the other hand, the net weight is the complete weight of the food commodity. Hence in the case of canned products, net weight may not give you the full picture, but the Legal Metrology rules mandates listing of the net weight of the commodity.
