EOU sector-specific compliance: approvals, value-add requirements, export controls, and restrictions on DTA sales and surplus power. Sector-specific conditions for EOUs require statutory or Board approvals for certain exports, mandate minimum value-addition for commodities like tea, spices and gems and jewellery, restrict third-party exports and job work for polyester yarn, and regulate sale of surplus power-permitting duty-free intra-EOU/SEZ transfers with GST applicability and NFE accounting while domestic sales require customs and state electricity permissions and duty as per revenue notifications.
