Let Export Order requirement: customs clearance must precede terminal entry, with document processing prioritised for reefers and perishables. A Standard Operating Procedure mandates issuance of a Let Export Order before export containers enter port terminals, with documentation to be completed at a new Document Processing Area in the Parking Plaza. This replaces checklist based gate approvals, reduces duplicate submissions, aligns Customs processing with Gate Automation and RFID systems, directs factory stuffed and self sealed containers away from Buffer Yard to the Document Processing Area or designated CFSs, and prioritises out of turn processing for refrigerated and perishable consignments marked on shipping bills.
