Concessional import duty for EOUs updated to align with current trade policy and GST, affecting exemptions and bond requirements. Notifications amend customs and central excise provisions governing EOUs/STPIs/EHTPs and DTA units to align with the present Foreign Trade Policy and GST regime. Imported goods may be temporarily cleared without payment of customs duties, IGST and compensation cess (with GST liability governed separately); duty on later DTA clearance is the duty exempted at import; depreciation for capital goods is preserved; redundant references and superseded provisions are removed; job worker GST registration and a revised B 17 bond with GSTIN references are mandated while existing bonds remain valid.
