Where goods are taken out of a free zone into another part of the customs territory of the Union or placed under a customs procedure, they shall be regarded as non-Union goods unless their customs status as Union goods has been proven.
However, for the purposes of applying export duty and export licences or export control measures laid down under the common agricultural or commercial policies, such goods shall be regarded as Union goods, unless it is established that they do not have the customs status of Union goods.
