The customs union has increased both imports and exports to Turkey and its GDP per capita.  Turkey`s accession to the customs union has played an important role in the transition of its economy from agriculture to industry.  The EU and Turkey meet regularly to discuss issues and best practices in implementing the agreement. Committees meet regularly. In December 2016, the European Commission published an assessment proposing to update and modernise the agreement, which includes services and public procurement.  The report ends with two options; Improved trade framework (ECF) or comprehensive free trade agreement (ACFTA).  Starting in 2020, the Council has not yet adapted the proposal. Since 2015, the Turkish government has held several meetings to assess the update of the agreement.  From 1 January 1996, Turkey began to abolish tariffs on industrial products and adopted the Community`s common tariff in its trade with third countries. Some of the exemptions in the decision were eventually abolished and, for processed agricultural products, tariffs on the industrial part of the global protection were abolished.
In addition, due to the obligations arising from Association Council Decision 1/95, Turkey`s foreign trade system is largely aligned with the EU customs code. In this context, the EU`s achievements in the areas of technical law, intellectual and industrial property rights, competition policy and EU legislation on the free movement of goods and the common trade policy is taken into account and expressed in our external trade system. Studies carried out within the framework of the customs union`s commitments can be summarized as follows: there are, however, some problems arising from the implementation of the customs union. The main difficulties can be summed up as follows: the risks of trade diversion and unfair competition resulting from the reluctance of some countries to partner in the EU Free Trade Agreement (FTA) to conclude similar agreements with Turkey, giving the EU the advantage of joining the Turkish market, the lack of adequate participation in EU decision-making mechanisms in the relevant areas of the customs union, as well as technical obstacles related to road quotas imposed by some EU Member States and taking into account visas for Turkish businessmen and truck drivers. The “final phase” under the Ankara agreement was to complete the creation of a customs union between the EC and Turkey. On 6 March 1995, the Association Council adopted a “decision on the customs union (Decision 1/95) ” on the implementation of the final phase of the customs union between Turkey and the EC. Thus, 22 years of “transition” were completed in the Additional Protocol on 1 January 1996 and the final phase of Turkey`s accession to the EU was launched.
