Extension of customs law to continental shelf and exclusive economic zone brings those maritime areas under customs regulatory and tariff regimes. The Central Government, under specified clauses of the Territorial Waters, Continental Shelf, Exclusive Economic Zone and Other Maritime Zones Act, 1976, extends the Customs Act, 1962 and the Customs Tariff Act, 1975 to areas of the Continental Shelf and the Exclusive Economic Zone designated by Government notification, thereby subjecting those maritime areas to the customs regulatory and tariff regimes effective from the date specified in the notification.
