Integration of the foreign trade sector of the national economy at the practical level is a reform of the bilateral trade regime through the liberalization of customs-tariff and non-tariff regulation, unification of the conditions for the international movement of production factors (investments, labor), and internal regulations that have an indirect impact on the development of foreign trade relations in order to eliminate economic barriers and the creation of a single market space between the parties to the integration association. Customs regulation of the foreign trade sector plays a key role in the national security system. At the present stage, this type of integration takes the form of concluding bilateral agreements on a deep and comprehensive free trade zone, which apply, inter alia, to environmental standards, government procurement, trade aspects of intellectual property rights, and the like. Based on the analysis, it is proved that the general structure of export supplies from Ukraine to the EU continues to be of a raw material nature: 52.8% of their value are agricultural raw materials, mineral resources, and primary processing products. The most adequate expansion of a deep and comprehensive free trade zone for modern realities is the vision of the role of the state as a systemic regulator, which, on the one hand, does not resort to the policy of isolationism, and on the other hand, acts as an active participant in the processes of international economic integration and entry into the most developed markets of the countries of the world, helping to increase the level of competitiveness of the foreign trade sector of the national economy.
