EOU eligibility governs approvals, LOP issuance, legal undertakings and B 17 bond compliance for export units. Eligibility for an EOU normally requires meeting a minimum investment threshold at commencement, subject to sectoral exceptions and BOA discretion; approvals are granted by a Unit Approval Committee chaired by the Development Commissioner and, where applicable, require BOA and industrial policy clearance. On approval the Development Commissioner issues a Letter of Permission detailing permitted manufacture and capital goods, after which the unit must execute a legal undertaking and a B-17 general bond. Conversion from a DTA unit under EPCG requires fulfilment of export obligations or payment of applicable duties and cess on capital goods.
