New Guidelines on Anti-Dumping Duties in Japan: What You Need to Know

On April 27, 2026, Japan’s Customs and Tariff Bureau released new guidelines regarding anti-dumping duties, a critical update for foreign entrepreneurs engaged in import activities. Understanding these regulations is essential for compliance and to avoid potential penalties. With Japan’s increasing scrutiny on unfair trade practices, foreign businesses must stay informed to navigate the complexities of customs regulations effectively.

Background & Context

The new guidelines on anti-dumping duties issued by the Customs and Tariff Bureau (Zeikan-kyoku) are part of Japan’s ongoing efforts to ensure fair trade practices. Anti-dumping duties are tariffs imposed on imported goods that are believed to be priced below fair market value, often to protect domestic industries from unfair competition. The legal framework governing these duties is primarily outlined in the Customs Act (Kanzei-hō) and the Anti-Dumping Act (Fuhō-shōhō), which were last amended in 2021. The guidelines aim to clarify the procedures for filing complaints and the criteria for determining whether goods are being sold at unfairly low prices. This regulatory update comes in response to increasing global trade tensions and aims to bolster Japan’s trade integrity. The guidelines detail the steps for businesses to report suspected dumping activities and the documentation required for investigations, ensuring transparency in the enforcement of these duties.
