Net Foreign Exchange requirement governs EOUs' duty free imports and export accounting ensuring positive foreign exchange contribution. The Chapter establishes the framework for EOUs, EHTPs, STPs and BTPs, defining procedures for application, approval, LoP/LoI issuance, and execution of Legal Undertakings. It prescribes permitted duty free imports and domestic procurement, conditions of utilisation tied to LoP validity, and SION or self declared input norms. Units must maintain positive Net Foreign Exchange (NFE) calculated as FOB exports less CIF value of imported inputs/capital goods and foreign exchange payments, with specified inclusions, amortisation and monitoring. DC/Designated Officers and UAC/BOA hold administrative and monitoring powers; status holders gain Fast Track Clearance privileges and time bound disposal of applications is mandated.
