Hazelnut, which has an important place in the export of agricultural sector, has been exported as hazelnut kernels and processed hazelnuts with the development of the hazelnut processing industry in Türkiye. This situation enabled the country to obtain more added value from the export of hazelnut products. This study aimed to reveal the structural characteristics of hazelnut cracking and processing companies in Türkiye. The primary data of the research were obtained by semi-structured questionnaires from 117 hazelnut cracking and processing companies in Türkiye using the full census method. The research findings show that hazelnut cracking and processing companies were concentrated in the main production area of Black Sea Region and their legal status were mostly limited company. The enterprises were generally medium and large-scale enterprises and they have been averagely operated for 22 years. The employees in production were generally women and the idle capacity of the firms were high. Only less than half of companies were exporter. Diversity in production and export were not high. Instead of new investments in the sector, modernization of existing enterprises, encouraging diversification and high value-added end products in processing, increasing the current capacity utilization rate and directing the companies towards export markets through vertical integration should be focused.
