During the period starting with the 1929 Great Depression and continuing until the Second World War, international trade volume experienced a great contraction. The countries aiming to abolish customs tariffs after the Second World War by a common decision, signed the General Agreement on Tariffs and Trade (GATT) in 1947. The GATT, which operated until the Uruguay Round in 1994, became the World Trade Organization (WTO) on that date. GATT (WTO since 1994) has made significant progress in reducing tariffs. The WTO aims to accelerate trade flows by removing customs tariffs and non-tariff barriers. In this context, the Trade Facilitation Agreement (TFA) was signed at the Bali Ministerial Conference in 2013. In this study, the process from the establishment of GATT to the present day is briefly examined. Furthermore, the benefits and costs of full implementation of the TFA were analyzed.The current position of Turkish foreign trade has been examined within the scope of reference international indicators during the implementation of the Agreement. The findings show that the Agreement will have a positive impact on the manufacturing industry in particular. Preliminary findings indicate that the possible impact will be less in the agricultural sector. It is understood that this sector, which has been under difficult conditions especially in developing countries since the Round of Uruguay, cannot be relieved by TFA, too. The idea of facilitating trade was first raised by the WTO at the 1996 Ministerial Conference of Singapore. However, although more than 20 years have passed since the conference in question, there is no comprehensive study on this subject in Turkish literature. The importance of this study is that it is the first comprehensive study in this field in Turkey
