Project import finalization timeframe: complete assessments within prescribed time limit, with commissioner-approved extensions and monitoring. Assessments under the Project Imports Regulations must be finalized within a prescribed time after submission of required documents, with the jurisdictional Commissioner able to extend the period for recorded reasons; bank guarantees must be maintained until finalization where documents are outstanding. Non-submission of reconciliation statements or prescribed documents under Regulation 7 may trigger enforcement of bonds, cash security or bank guarantees, adjudication for duty demand and penalty. Provisionally assessed Bills of Entry at ports other than the registration port must be finally assessed without delay. Plant Site Verification and Chartered Engineer certificates are required to confirm installation and use. Commissioners must maintain records, monitor pendency, and submit monthly and quarterly reports through prescribed formats to enable centralized oversight.
