This article analysed trends in the development and diversification of Ukraine’s oils export markets. It examines the impact of globalisation processes, economic integration, and international competition on the structure of exports, as well as the role of state support mechanisms for exporters. The study employed a combination of statistical, analytical, and comparative methods, along with a systematic approach to assessing the competitiveness of oil and fat products in global markets. Export diversification was carried out in three main directions: expanding the geography of supply and increasing the number of importing countries, reorienting logistics routes and utilising alternative transport corridors, and diversifying the product structure by increasing the share of different types of oils and their processed products. A gradual increased in exports of soybean and rapeseed oil, meals, and oilcake was noted, contributing to higher added value and the formation of a more resilient system of foreign markets. The main constraints hindering effective diversification were identified as stricter technical and phytosanitary requirements, an insufficient level of transport and logistics infrastructure development, fluctuations in global prices, and a high level of competition. To overcome these barriers, a set of state support measures was proposed, including the modernisation of logistics, the development of trade and economic diplomacy, marketing support, and the stimulation of deep processing of oilseed crops. Market diversification is a strategic tool for ensuring economic resilience and enhancing the competitiveness of Ukraine’s oil and fat industry in the context of global instability and the transformation of the international trading system. The practical significance lies in identifying effective directions for diversifying foreign markets for Ukraine’s oil and fat products, which can be used by public authorities and industry enterprises to improve export competitiveness and resilience
