Guidelines on Procedures for Anti-Dumping Duties and Related Measures

On April 25, 2026, Japan’s Customs and Tariff Bureau released new guidelines regarding anti-dumping duties, a crucial update for foreign entrepreneurs engaged in import and export activities. Understanding these regulations is vital for businesses to avoid potential penalties and ensure compliance when trading in Japan.

Background & Context

The legal framework governing anti-dumping duties in Japan is primarily established under the Customs Act (Shunyu-jiho) and the Anti-Dumping Act (Fuhō Rōdō Hō) of 1994, which was last amended in 2021. Anti-dumping duties are imposed to protect domestic industries from foreign companies selling products at unfairly low prices. The guidelines released by the Customs and Tariff Bureau (Zōkei-tō) aim to provide clarity on the procedures for filing complaints and the criteria used to determine whether dumping has occurred.

How This Affects Your Business in Japan

1. Foreign Residents Already Operating a Business in Japan
If you are currently importing goods, it is crucial to review the new guidelines to ensure your pricing strategies comply with anti-dumping regulations. Failure to do so could result in hefty fines or the imposition of anti-dumping duties on your products. You should conduct a thorough assessment of your pricing and sourcing strategies by the end of Q2 2026. Documentation such as invoices, contracts, and pricing structures may be required for compliance checks.

2. Foreign Nationals Planning to Establish a New Company
For those looking to start a business in Japan, understanding these guidelines is essential before entering the market. Ensure that your business model does not inadvertently violate anti-dumping regulations. It is advisable to consult with a legal expert specializing in Japanese trade law to ensure compliance from the outset. Prepare to gather necessary documentation, including business plans and pricing strategies, by the time of your business registration.

3. Foreign Investors Who Are NOT Residents of Japan
If you are considering investing in Japanese companies or markets, it is vital to be aware of how anti-dumping duties could affect your investment. Conduct due diligence on potential investments and assess the risk of anti-dumping actions. Engaging with local legal counsel can provide insights into compliance and help mitigate risks associated with your investments. Ensure you have a clear understanding of the market dynamics before making any investment decisions.
