A policy was introduced in the EXIM Policy effective from 1.4.2000 for setting up of Special Economic Zones in the country with a view to provide an internationally competitive and hassle free environment for exports. Units may be set up in SEZ for manufacture of goods and rendering of services. All the import/export operations of the SEZ units will be on self certification basis. The units in the Zone have to be a net foreign exchange earner but they shall not be subjected to any pre-determined value addition or minimum export performance requirements. Sales in the Domestic Tariff Area by SEZ units shall be subject to payment of full Custom Duty and import policy in force. Further Offshore banking units may be set up in the SEZs.
