Assignment of customs functions enables the Board to allocate responsibilities and Commissioners to delegate within their jurisdiction. The Board may, by notification, assign functions to an officer of customs who shall be the proper officer for those functions; within assigned jurisdiction, the Principal Commissioner or Commissioner may, by order, similarly assign functions. The Board may set conditions and limitations using criteria such as territorial jurisdiction, persons, goods, cases, computer-assigned random assignment, or other notified criteria, and may require two or more officers to have concurrent powers and functions by notification.
