In the current security context of the Black Sea region, trade relations are affected by the imperative of international sanctions, which have imposed a series of restrictions that make it difficult for professionals to carry out commercial contracts. Through the 12 packages of restrictions established by the EU, following Russia's invasion of Ukraine, the supply of raw materials from the East and exports to these destinations are largely blocked. The risk of fraud is evident as long as production facilities are designed for the use of certain categories of goods in the supply chain, which are currently under economic embargo or directed toward specific markets. Integrated border management is a priority for authorities, and consolidating cooperation for customs risk management involves adopting exceptional measures. This study aims to identify the gaps in the Union's regulatory framework regarding risks and the critical knowledge of control authorities regarding the processes defined for processing customs and commercial documents within import-export operations at the Union's external eastern border. The scope, interpretation, and effects of European and international legal provisions constitute a separate analysis of the exceptional nature of international sanctions.
