Customs exemption for imported gold and silver limits duty payable by authorised agencies to notified rates and waives additional duty. The notification exempts imports of gold and silver by specified trading agencies for domestic sale from customs duty in excess of rates notified and from the whole of the additional duty under the Customs Tariff Act; it includes medallions and coins within the scope of gold and silver but excludes jewellery and foreign currency coins, and was later superseded by a subsequent notification.
