Auxiliary duty amendment adds a new schedule entry under customs notification, invoking statutory amendment powers. The Central Government, invoking sub-section (1) of section 25 of the Customs Act, 1962 and sub-section (4) of section 64 of the Finance Act, 1990, amends Notification No. 180/90-Customs by inserting after Sl. No. 278 a new Sl. No. and entry in the Schedule, thereby adding a reference to the newly issued departmental notification.
