Verification and monitoring of export authorizations ensure EO compliance, EODC checks and bond redemption controls under customs procedures. Holders of AA, DFIA, EPCG and post export EPCG must keep proper accounts and show the AA number on export documentation; EO fulfilment is monitored by submission of documents to the RA for issuance of an EODC, failure of which requires deposit of Customs duties with interest. Customs uses EODCs/redemption letters for bond or bank guarantee redemption subject to prescribed and intelligence based checks, and Commissioners must monitor EO via EDI data, periodic RA coordination, MIS updates, notices to defaulters, and random verifications including address and installation certificate checks (5% limit).
