Customs amendment adds a new schedule entry to an existing exemption notification, expanding auxiliary duty coverage. The Central Government, invoking powers under the Customs Act and the Finance Act and in the public interest, amends Notification No. 312/86-Customs by inserting after Sl. No. 274 a new Sl. No. 275, recording No. 431/86-Customs dated 19th September 1986, thereby formally adding that auxiliary duty exemption notification to the schedule.
