Auxiliary duty amendment: new customs notification added to the exemption schedule, expanding the prior notification's entries. The Central Government, invoking statutory powers under the Customs Act and the Finance Act, amends Notification No.161/89-Customs by inserting after serial number 99 a new serial number 100 with the entry 'No. 6/90-Customs, dated 23rd January, 1990,' thereby adding that notification to the Schedule of the earlier notification.
