Guidelines on Procedures for Anti-Dumping Duties and Related Matters

On April 26, 2026, Japan’s Customs and Tariff Bureau released updated guidelines on anti-dumping duties, essential for foreign entrepreneurs involved in import and export activities. Understanding these regulations is crucial for businesses to avoid penalties and ensure compliance.

Background & Context

The guidelines issued by the Customs and Tariff Bureau (Zeikan-kyoku) clarify the procedures and criteria for imposing anti-dumping duties on imported goods sold at unfairly low prices. These measures protect domestic industries from foreign competition that may distort market conditions. The framework is governed by the Customs Act (Zeikan-ho) and the Anti-Dumping Act (Fukuzatsu Hanbai-ho), last amended in 2021. The guidelines detail procedures for complaints, investigations, and dumping margin assessments. They take effect immediately, urging businesses to comply to avoid penalties.

If you are currently importing goods into Japan, it is crucial to review your pricing strategies to ensure compliance with the new anti-dumping guidelines. You may need to gather documentation to prove that your pricing is not below fair market value. Failure to comply could result in significant tariffs being imposed on your imports. It is advisable to consult with a trade compliance expert or legal advisor familiar with Japanese customs regulations.

2. Foreign Nationals Planning to Establish a New Company
For those looking to start a new business in Japan that involves importing goods, understanding these anti-dumping regulations is essential. You will need to prepare a comprehensive business plan that includes pricing strategies that comply with the new guidelines. Additionally, ensure that you have the necessary documentation ready for customs clearance. Consider reaching out to local business support organizations for assistance in navigating these regulations.

3. Foreign Investors Who Are NOT Residents of Japan
If you are considering investing in Japanese companies that import goods, it is vital to assess the potential risks associated with anti-dumping duties. Conduct thorough due diligence on the companies you are interested in, focusing on their compliance with the new guidelines. Engaging a local legal advisor can help mitigate risks and ensure that your investment is protected against unexpected tariffs.
