This study investigates the impact of Technical Barriers to Trade (TBT) and unnotified technologies on South Korea’s foreign exports, analyzing the background and objectives. With the expansion of regional economic blocks such as FTAs, the EU, and NAFTA, the scope of non-tariff barriers, including TBT and Sanitary and Phytosanitary (SPS) measures, has broadened. These non-tariff barriers, often implemented for safety purposes like environmental protection, can increase shipping and compliance costs, imposing a burden on domestic industries. The main objective of this study is to quantitatively evaluate the effects of TBT and unnotified technologies on South Korea's exports across various industries from 1995 to 2022. To achieve this, we employ the gravity model, one of the most widely used models in explaining trade conflicts, alongside the Poisson Pseudo Maximum Likelihood (PPML) method, which is suitable for handling the complexities of trade data with zero trade flows. This approach enables a detailed analysis of the impact of TBT and unnotified technologies on export performance, disaggregated by objective and industry. The results reveal that while TBT has a positive effect in promoting exports, unnotified technologies have a negative impact. These findings highlight the importance of distinguishing between the two in international trade negotiations.
