Special Economic Zones regime: substitution of Foreign Trade Policy references and narrowed customs exemptions for certain goods. Directs substitution of references to the Foreign Trade Policy with the Special Economic Zones Act and Rules in specified customs notifications, replaces the Explanation to define 'Special Economic Zone' by section four of the SEZ Act, inserts a proviso excluding a specified list of electronic and communication goods from an exemption in Notification No. 45, and omits S.No. seven and its entries from the Table in Notification No. 20, thereby aligning customs exemptions and definitions with the SEZ statutory framework.
