Paperless Customs Single Window enables electronic BE messages and agency Release Orders to accelerate cargo clearance procedures. The Board advances a paperless Customs clearance regime via a Single Window enabling electronic BE messages and Release Orders from PGAs (FSSAI, PQIS, AQCS), with OOC withheld until required ROs are received. Complementary measures mandate uploading of invoices and transport contracts on eSANCHIT, accept combined invoice/packing lists, dispense with SDF on declaration, require Digital Signatures for filings, deploy ICETAB for examination, implement an Electronic Cash Ledger, and expand automated modules and PGA onboarding to speed clearance and reduce physical documentation.
