Electronic sealing requirement: voluntary transition now, mandatory at specified ports from March and elsewhere from April. Entitled exporters with RFID e seals stuffing containers at approved premises where readers exist may voluntarily adopt electronic sealing until 1 March 2018. From 1 March 2018 electronic sealing is mandatory for exporters permitted self sealing previously, AEO exporters, and those availing supervised stuffing at their premises at fifteen specified Ports/ICDs. At all other Ports/ICDs the procedure becomes mandatory from 1 April 2018. Exporters already using e seals may continue; those under officer supervision retain that facility until mandatory implementation. Difficulties are to be reported to the Preventive General office.
