Guidelines on Anti-Dumping Duties in Japan: Essential Information for Businesses

Japan has released updated guidelines on anti-dumping duties, crucial for foreign businesses engaged in import and export activities. Understanding these guidelines is vital for compliance with Japanese customs regulations, affecting pricing strategies and market competition.

Background & Context

The updated guidelines on anti-dumping duties in Japan are issued by the Ministry of Finance’s Customs and Tariff Bureau (Zaimu-shō Kansetsu-kyoku). These measures protect domestic industries from unfairly low-priced foreign goods. Governed by the Customs Act (Kanzei-hō) and the Anti-Dumping Act (Fukōdōbai-hō), last amended in 2021, the guidelines clarify procedures for complaints and criteria for determining dumping. Published on April 24, 2026, they enhance transparency in trade regulations, detailing documentation and processes for anti-dumping investigations.
