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

On April 25, 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 guidelines is essential for businesses to navigate potential tariffs effectively and ensure compliance with Japanese trade regulations. This change could impact pricing strategies and market entry for foreign companies, making it crucial to stay informed and prepared.

Background & Context

The new guidelines issued by the Customs and Tariff Bureau (Zeikan-kyoku) address procedures related to anti-dumping duties, which are tariffs imposed on foreign imports believed to be priced below fair market value. This regulatory framework is governed by the Customs Act (Zeikan-hō) and the Anti-Dumping Act (Fukuzatsu Shōhi Shōhō), which aim to protect domestic industries from unfair competition. The guidelines outline the process for filing complaints and the criteria for determining whether an anti-dumping duty should be applied. The last significant amendment to these regulations occurred in 2021, reflecting Japan’s ongoing efforts to align its trade practices with international standards. The recent update aims to enhance transparency and provide clearer instructions for foreign businesses, ensuring they understand their rights and obligations under Japanese law.
