The person in charge or in control of any vehicle, vessel or aircraft shall, if required to do so by the officer of customs, stop his vehicle, vessel or aircraft or move the same to another place for examination, and shall not proceed until permission to do so has been given by the officer of customs.

An officer of customs may, within a free trade zone, examine any goods which are being taken into or removed from a free trade zone and for the purpose of such examination bring the goods to the office of customs and may open any container, package or receptacle.
