Duty-free import procedures: EOUs may import on importer-submitted information without prior jurisdictional approval under applicable customs rules. Importer-submitted information to the Customs officer at the port of import is sufficient to secure duty-free treatment under the concessional import rules; prior approval or signed forwarding by the jurisdictional DC/AC is not a prerequisite, though the jurisdictional office must thereafter scrutinize and forward its copy so the port office can reconcile Bills of Entry and address discrepancies to protect revenue.
