Further to an earlier message regarding the calculation of duty on weight, members should be aware that duty is calculated on the net weight of the goods. This information is found in paragraph 7 of the Customs Tariff which states:
Weight of goods
7 For the purposes of this Act, if a rate of customs duty is based in whole or in part on the weight of goods, the customs duties imposed on the goods are, unless otherwise provided, to be calculated on the basis of the net weight of the goods.
