Customs exemption for precious metals imported under designated export schemes prescribes specific duty treatments and full relief in certain supply schemes. The notification amends the customs exemption for imports of gold, silver and platinum under specified Foreign Trade Policy schemes by substituting a table that prescribes scheme-specific duty treatment: replenishment under exhibition/branding schemes attracts specified reduced duties for gold and silver and full relief for platinum, while imports under the Export Against Supply by Nominated Agencies scheme attract full exemption from basic customs duty; the amendment omits the third proviso and preserves exemption from additional duties under section 3 as specified.
