Concessional import regime requires prior IGCR registration, continuity bond, detailed records and monthly compliance statements. The rules require importers to file one time prior information (Form IGCR 1) to obtain an IIN and to furnish a continuity bond when availing notification benefits. Importers must declare IIN and bond details in the bill of entry, maintain detailed records, and submit monthly statements on the common portal. The regime prescribes controls for job work, unit transfer and end use supplies, permits re export or duty payment for unutilised or defective goods, allows clearance of capital goods after depreciation, and enables recovery and penalties for non compliance.
