Customs notification amendments expand port designations and permit transfers after bond redemption, with export obligation relief provisions. Multiple customs exemption notifications are amended to substitute specified port designations, include Special Economic Zone references, revise duty-exemption wording to address safeguard and anti-dumping duties, permit transfer of unutilised material after bond redemption subject to central excise job work procedure, allow intra group actual user transfers, introduce a mechanism to condone remaining export obligation where 75% is met early, and grant the Commissioner discretion to permit alternative ports or customs stations.
