Guidelines on Anti-Dumping Duties and Procedures in Japan

On April 27, 2026, Japan’s Customs and Tariff Bureau released new guidelines on anti-dumping duties. This update is crucial for foreign entrepreneurs and business professionals as it clarifies the procedures and regulations surrounding unfair trade practices. Understanding these guidelines is essential for compliance and to avoid potential penalties when importing goods into Japan. Foreign businesses must stay informed to navigate the complexities of Japan’s trade regulations effectively.

Background & Context

Japan’s legal framework for trade is governed by various laws, including the Customs Act (Shunyu-hō) and the Anti-Dumping Act (Futō Renbai-hō). The Customs Act regulates the import and export of goods, while the Anti-Dumping Act specifically addresses unfair pricing practices that harm domestic industries. The recent guidelines issued by the Customs and Tariff Bureau (Zōzei Kyoku) aim to enhance transparency and provide a clear procedural framework for addressing anti-dumping cases. These guidelines come in response to increasing global trade tensions and the need for Japan to protect its market from unfair competition. The last significant amendment to the Anti-Dumping Act was in 2021, which introduced stricter measures against dumping practices. The new guidelines are expected to streamline the process for both the government and businesses, making it easier to report and address suspected dumping activities.
