Abstract: There are principles and restrictions of the international trade influencing not only the export potential of the country, but also its internal market and food security. The object of research is foreign economic activity connected with the export of raw materials and processed products of the oil and fat industry. The research subject is the fundamental trade principles of the WTO which can have an impact on the volumes of export of the oil and fat industry established by the Federal project “Agricultural products export”. The authors consider trade regimes and principles common for all member-states, and the relatively recent changes in export financing. In the Russian Federation, the complex agricultural products export support system is functioning. This system is included in the National project “International cooperation and export”, and the project “Agricultural products export” is part of it. Within the federal project, various instruments of exporting agriculture producers support are used, both of financial and non-financial nature, which are implemented via various institutes for development. The key factor of the topical character of this research is the restriction of agricultural products export financing and the provision of Russia’s food security. The authors analyze tariff regulation of oil and fat products trade and formulate the variants of development of this sector.
