EC preferences: imports from Turkey

Waiver of formal documentary evidence requirement: other private importations

Goods not intended for commercial use imported by a private individual in any one consignment, which are not otherwise provided for in this section may be admitted to Turkish preference without the production of formal documentary evidence. However, you should be satisfied, from the evidence available and from any examination of the goods, that they are entitled to Turkish preference.
