EOU DTA sales permission expanded: domestic sales allowed against full duties where NFEP and export performance conditions are met. EOU/EPZ/EHTP/STP units may sell finished products in the domestic tariff area beyond prior limits against payment of full duties if the goods are freely importable or imported under licence and the units have achieved stipulated NFEP and export performance; supplies to DTA that count toward export performance include certain defence and security force procurements where duty-free import entitlement exists; job-worker exports require Central Excise registration and disallowance of third party routing, with scrap at job worker premises either cleared on duty payment or returned to the supplier.
