Risk-based selectivity for customs clearance directs PGA referrals and targeted inspections through a single electronic window. Under the integrated declaration framework, consignments are automatically routed to Participating Government Agencies (PGAs) for necessary permissions without separate approaches by importers or exporters. A risk-based selectivity mechanism in the Risk Management System (RMS), using PGA-defined risk criteria and delegated authority, generates instructions for documentary checks, inspections/examinations and sample drawal that appear on customs officers' screens, enabling simultaneous processing by Customs and PGAs to reduce dwell time and transaction costs.
