Decentralization of AEO application processing enables local filing with zonal authorities and central programme coordination. AEO application processing is decentralized: applications are to be filed with the jurisdictional Chief Commissioner's office with copy to the AEO Programme Manager at the Directorate of International Customs; the Directorate will serve as AEO Programme Manager and together with zonal officers will form the AEO Programme Team. Applicants must show three years' solvency and absence of insolvency or customs duty default; solvency certificate requirements differ by AEO tier. AEO certificate validity and client relationship manager nomination requirements are prescribed, and certain advance authorisation provisions on self declaration are added.
