This study aimed to quantitatively assess Türkiye’s export performance in the EU28 hazelnut market (kernel basis) from 2010 to 2021 by applying the constant market share (CMS) method to identify and measure the key factors influencing competitiveness over time. Türkiye’s market share in the European hazelnut market increased and the commodity composition effect made the largest contribution, showing that hazelnut is the right export product for the target market. However, some components, namely, the market share effect for 2010–2013 vs. 2014–2017, the commodity adaptation effect for 2010–2013 vs. 2018–2021, and the market composition effect for 2014–2017 vs. 2018–2021, had the largest negative impact on market share, indicating performance areas where Türkiye was not successful. Türkiye needs to undertake a comprehensive review of its competitive strategies, with particular emphasis on product quality, to facilitate further growth of its hazelnut exports within the European market.
