Disposal of duty-free vehicles by privileged persons now governed by Foreign Privileged Persons Rules, enabling regulated sales to non-privileged buyers. The amendment replaces the former restriction that duty free vehicles imported by foreign diplomats and privileged persons could only be sold to other privileged persons and had to be re exported, with a provision that such vehicles shall be disposed of in the manner specified in the Foreign Privileged Persons (Regulation of Customs Privileges) Rules, 1957, as amended.
