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

Japan has recently published new guidelines regarding anti-dumping duties, a critical aspect for foreign entrepreneurs involved in import and export activities. Understanding these regulations is essential for avoiding potential penalties and ensuring compliance when bringing goods into the Japanese market. This update is particularly relevant for businesses that may be affected by unfair pricing practices, as it outlines the procedures and implications of anti-dumping duties.

Background & Context

The new guidelines on anti-dumping duties have been issued by the Japan Customs (Nihon Zeikan) to provide clarity on the procedures involved in addressing unfair pricing practices in international trade. Anti-dumping duties are tariffs imposed on foreign imports believed to be priced below fair market value, which can harm domestic industries. The legal framework governing these duties is primarily established under the Customs Tariff Act (Kanzei Teiritsu-hō) and the Foreign Exchange and Foreign Trade Act (Gaikoku Kawase oyobi Gaikoku Bōeki-hō). The guidelines aim to streamline the process for businesses and improve compliance with international trade standards. The last significant amendment to the Customs Tariff Act occurred in 2021, reflecting Japan’s commitment to adapting its trade regulations in line with global practices. The guidelines were officially published on April 28, 2026, and are intended to assist both domestic and foreign businesses in navigating the complexities of anti-dumping regulations.
