Self-sealing permission registration remains valid unless withdrawn, with interim EDI extensions and approval required for specified amendments. Self-sealing permission granted to an eligible exporter or merchant exporter has no prescribed validity period and continues unless withdrawn, suspended or cancelled. EDI registration validity for fresh and existing permissions is extended up to 31 March 2027, followed by annual extensions by the FSP Cell without fresh approval until system enhancement. Permissions expressly issued for a fixed period require renewal from the jurisdictional Commissionerate. Amendments to premises, authorised signatory or ROC particulars require jurisdictional approval and intimation to the FSP Cell.
