This paper examines the effects of cross-border trade barriers, such as tariffs and quotas, on global supply chain stability. In recent decades, the interconnected nature of global supply chains has made them susceptible to external disruptions, with trade protectionism emerging as a significant factor contributing to such instability. The research focuses on understanding how various trade barriers impact the flow of goods, increase production costs, and disrupt established supply chain networks. The paper provides an overview of the mechanisms through which trade barriers cause shifts in supply chain structures and production practices, including changes in supplier relationships and technological adoption. Furthermore, it explores the strategies that businesses implement to adapt to these challenges, such as supplier diversification and regional cooperation. The paper concludes by evaluating the future trajectory of global supply chains in the context of persistent protectionism, highlighting the importance of technological innovation and strategic flexibility in ensuring supply chain resilience. This study underscores the need for global cooperation and adaptive strategies in mitigating the negative impacts of trade barriers, offering a positive outlook on overcoming these challenges and maintaining stable global trade systems.
