This paper aims to highlight the underlying evolution of economic integration within the European Union and non-tariff barriers influence in the area of commerce that refer to direct or indirect discriminatory measures against foreign goods and / or producers. It also seeks to examine the problems and experiences of countries in their use by governments to restrict, limit or facilitate trade relations. The most important element of all is the fact that certain institutions and habits have been formed within the European community. Government representatives have come to realize that the actions of any one country may seriously affect others, and new forms of inter-governmental consultation have developed. In a world where economic life is so greatly affected by government actions of one kind or another, this new intimacy is of major importance. On the other hand, non-tariff protection has strengthened, gradually replacing the tariff. The importance of non-tariff regulations has been steadily increasing over the past decades. This is due to the increasingly limited efficiency of the customs regime and to the fact that international negotiations have gradually brought about a weakening of tariff protection; the interest in using even non-tariff restrictions in all trade policy regulations is also due to the international trade trends of recent years.
