Community on or after the date of signature of this Protocol.Article 31. Chapter I, Section I, and Chapter II of this Title shall likewise apply to goods obtained or produced in the Community or in Turkey, in the manufacture of which were used products coming from third countries and not in free circulation either in the Community or in Turkey. These provisions shall, however, apply to those goods only if the exporting State charges a countervailing levy, the rate of which is a percentage of the duties laid down in the Common Customs Tariff for third country products used in their manufacture. This percentage, fixed by the Council of Association for each of such periods as it may determine, shall be based on the tariff reduction granted on those goods in the importing State. The Council of Association shall also lay down the rules for the countervailing levy, taking into account the relevant rules in force before 1 July 1968 in trade between Member States.2. The countervailing levy shall not, however, be charged on exports from the Community or from Turkey of goods obtained or produced under the conditions mentioned in this Article while the reduction of customs duties on the majority of goods imported into the territory of the other Contracting Party does not exceed 20%, taking into account the various timetables for tariff reductions fixed by this Protocol.Article 4The Council of Association shall determine the methods of administrative cooperation to be used in implementing Articles 2 and 3, taking into account the methods laid down by the Community with regard to trade between Member States.Article 51. If either Contracting Party considers that differences arising from the application to imports of customs duties, quantitative restrictions or any measures having equivalent effect, or from any other measure of commercial policy, threaten to deflect trade or to cause economic difficulties in its territory, it may bring the matter before the Council of Association, which shall, if necessary, recommend appropriate methods for avoiding any harm liable to result therefrom.2. Where deflections occur or economic difficulties arise and the Party concerned considers that they call for immediate action, that Party may itself take the necessary protective measures, and shall notify the Council of Association thereof without delay; the Council of Association may decide whether the Party concerned shall amend or abolish those measures.3. In the choice of such measures preference shall be given to those which least disturb the operation of the Association and, in particular, the normal development of trade.Article 6During the transitional stage the Contracting Parties shall, in so far as may be necessary for the proper functioning of the Association, take steps to approximate their law, regulation or administrative action in respect of customs matters, taking into account the approximations already effected by the Member States of the Community.CHAPTER ITHE CUSTOMS UNIONSection IElimination of customs duties between the Community and TurkeyArticle 71.

The second and third shall be applied three years and five years later.
