This article analyzes the concept and characteristics of customs authorities’ competencies in Ukraine within the context of ongoing innovations in customs practices. As Ukraine pursues its Euro-integration goals — aimed at modernizing economic infrastructure, overcoming technological lag, attracting foreign investments, and enhancing international competitiveness — customs authorities play a pivotal role in ensuring the effective functioning of foreign economic activities. The focus of the article is on the necessity to modernize the competencies of customs authorities in line with global standards and to implement advanced innovative technologies, as outlined in Ukraine’s Innovation Development Strategy up to 2030. It examines the impact and significance of innovations such as the ‘Single Window’ system, ‘Smart Customs’ initiatives, pre-arrival cargo information technologies radio-frequency identification (RFID), and blockchain for enhancing customs control, management, and interactions with external partners. A central issue discussed in the article is the development of new competencies required for the effective implementation of these innovations by customs authorities. Specifically, it addresses the need to cultivate digital, intellectual, partnership, and security skills. The article also explores the effects of economic and political instability, particularly the wartime conditions in Ukraine, on the implementation of innovations in customs operations. Key challenges are identified, such as difficulties in exporting high-tech goods, granting incentives for importing innovative equipment, and applying non-tariff regulatory measures, including certification, quotas, and licensing. Recommendations are provided for improving the organizational structures of customs authorities and updating the legal and regulatory framework to adapt to modern requirements and standards. The article advocates for the development of a new, intelligent customs system that can swiftly and effectively respond to changes by employing cutting-edge digital technologies and security methods. Emphasis is placed on the importance of enhancing the qualifications of customs professionals, which is essential for the successful implementation of innovations in customs control.
