Analyzing South Korea’s Semiconductor Industry: Trade Dynamics and Global Position

U.S. sanctions on China's semiconductor industry are causing major shifts in the global supply chain, affecting South Korea's industry due to its reliance on Chinese manufacturing. The Biden administration's increased sanctions, combined with global trends towards semiconductor self-sufficiency, are putting South Korea's semiconductor position at risk. Countries such as the U.S., China, and Japan are building up their domestic semiconductor industries, potentially affecting South Korea's position in the global market. Deeply integrated with China, Korean companies, face the challenge of reducing this dependence and adapting to the evolving supply chain landscape. This paper examines the import and export trends of the South Korean semiconductor industry over the last five years to assess its global standing, identify challenges, and suggest strategic directions. Using data from the Korea Customs Service from 2019 to 2023, the study analyzes trade patterns and supply chain configurations within South Korea's semiconductor industry. The industry is divided into six main categories and 33 subcategories, based on the analysis of 381 semiconductor-related items categorized under the Harmonized System at the 10-digit level. This detailed classification allows for an in-depth examination of trade trends, supply chain structures, and associated risks within the South Korean semiconductor industry. Moreover, this research uses the classification method described and UN Comtrade statistics to create a dataset on global semiconductor trade. This dataset is used to analyze the international presence of the South Korean semiconductor industry and its market shares in China across different segments.
