Refund of IGST on export: officer-interface extended to more shipping bills and alternative documents accepted. The Board expands the officer interface alternate mechanism to permit correction of invoice mismatches for additional shipping bills, enabling administrative resolution of export refund impediments through verification against GST return information. It also accepts final Bills of Lading or gateway port custodian confirmations as substitutes for transference copies in EGM integration and authorises a one time officer interface verification to permit IGST refund where exporters misdeclared payment status.
