Electronic sealing requirement phased from voluntary adoption to mandatory use for eligible exporters and approved premises. Exporters with RFID e-seals stuffing containers at approved premises where readers are available may voluntarily adopt e-sealing immediately; the regime will transition to mandatory application for exporters permitted self-sealing and AEO exporters or those availing supervised stuffing at their premises for export through the Customs jurisdiction, with a later mandatory start for a specified ICD. EDI registration validity at the Port of Export is extended until the ICD mandatory start date. Difficulties should be notified to Customs.
