Jurisdictional appointment of customs commissioners establishes territorial administrative control and reporting lines for customs operations. The Central Board of Excise and Customs appoints specified officers as Principal Commissioners/Commissioners, Additional or Joint Commissioners and Deputy or Assistant Commissioners of Customs, and assigns them to discrete territorial and functional zones (ports, airports, ICDs, SEZs, districts, states and designated maritime areas). For each zone the Additional/Joint Commissioners and Deputy/Assistant Commissioners are declared to work under the control of the named Commissioner or Principal Commissioner, establishing supervisory and reporting relationships. The notification supersedes an earlier notification and sets an operative commencement date.
