Appointment of Customs Officers supersedes prior notification and designates national and rule based commissioners, deputies, and assistants. The Central Government, exercising powers under the Customs Act, appoints the Director General of Revenue Intelligence and the Director General of Inspection, Customs and Central Excise as Commissioners of Customs with nationwide jurisdiction, and appoints Commissioners of Central Excise as Commissioners of Customs within territorial limits specified by the Central Excise Rules, 1944; deputy and assistant commissioners posted under those Commissioners are designated as Deputy Commissioners of Customs and Assistant Commissioners of Customs within their respective jurisdictions.
