Permission for customs clearance at non-notified seaports requires Board approval after jurisdictional verification and forwarding. Requests for customs clearance at non-notified sea ports for government-project imports requiring Board approval must include supporting documents from the government agency or beneficiary and any required NOC; third-party requests need importer authorization. Such requests are to be addressed to the jurisdictional Principal Commissioner or Commissioner of Customs (Port) except in urgent cases for direct Board consideration. The jurisdictional Customs office must verify the authenticity of submissions, may seek further evidence, and, once satisfied, forward the request with a verification report to the Board for approval.
