AEO status maintenance requires prompt notification of significant business changes and voluntary disclosure of customs errors. Maintenance of AEO status requires holders to notify the AEO Programme Team of significant business or process changes-such as legal entity, name or address, nature of business, accounting or IT systems, senior customs personnel, and supply chain locations-promptly and within fourteen days. A change of legal entity necessitates reapplication in the new entity's name. Customs-related errors must be reported to the local Client Relationship Manager and the AEO Programme Team; voluntary disclosure protects status if causes are examined and remedial measures implemented.
