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

The Japanese government has released new guidelines regarding anti-dumping duties, a critical regulatory change that foreign entrepreneurs must understand. These guidelines outline the procedures for addressing unfair pricing practices that can affect import costs and market competition. For foreign businesses operating or planning to enter the Japanese market, understanding these regulations is essential to avoid unexpected tariffs and ensure compliance with local laws.

Background & Context

Japan’s trade regulations, particularly concerning anti-dumping duties, are governed by the Customs Act (Kanzei-hō) and the Foreign Exchange and Foreign Trade Act (Gaikoku Kawase Oyobi Gaikoku Bōeki Hō). Anti-dumping measures are designed to protect domestic industries from foreign companies selling products at unfairly low prices. The new guidelines, released by the Ministry of Finance (Zaimu-shō), provide detailed procedures for businesses to follow when they believe they are subject to anti-dumping duties. This regulatory framework has evolved over the years, with significant amendments made to the Customs Act in 2019 and 2021 to enhance transparency and fairness in trade practices. The latest guidelines, published on April 27, 2026, aim to clarify the application process and criteria for imposing anti-dumping duties, ensuring that foreign businesses understand their rights and obligations under Japanese law.
