Risk-based NOC waiver for low-risk consignments allows clearance without PGA approval; exceptions require senior officer authorization. Under the Single Window, automated risk-based selectivity will refer Bills of Entry to PGAs for NOCs based on risk; low-risk consignments will have PGA NOCs waived with an on-screen and printed waiver message, and Customs officers must not manually refer such consignments except with Assistant/Deputy Commissioner approval. The RMS will issue instructions for documentary checks, inspections and sampling, and importers and brokers must accurately declare end-use and product details in the Integrated Declaration.
