Customs duty increase on precious metal imports and spent catalyst entries under the amended notification framework. The customs notification amends the existing exemption framework by increasing the applicable rate of customs duty from 5% to 10% for specified entries in Table I relating to gold, silver, platinum, precious metal goods, and related articles. It also inserts a new entry for spent catalyst or ash containing precious metals at 10%, subject to a sunset provision that limits its effect after 31 March 2027. The amendment further substitutes the entry for other goods under the relevant precious metal tariff headings so that, except for the newly inserted spent catalyst or ash category, those goods attract customs duty at 10%. The notification takes effect from 13 May 2026 and operates as a further amendment to the principal customs notification governing these specified imports.
