Partial Revision of Guidelines on Anti-Dumping Duties Procedures

On April 23, 2026, Japan’s Customs and Tariff Bureau announced significant updates to the guidelines regarding anti-dumping duties. This change is crucial for foreign entrepreneurs and businesses engaged in import activities, as it directly impacts the cost structure and compliance requirements for imported goods. Understanding these updates is essential for navigating Japan’s trade landscape effectively and avoiding potential penalties.

Background & Context

The legal framework governing anti-dumping duties in Japan is primarily established under the Customs Act (関税法, Kazei-hō) and the Foreign Exchange and Foreign Trade Act (外国為替及び外国貿易法, Gaikoku Kawase Oyobi Gaikoku Bōeki-hō). These laws aim to protect domestic industries from unfair competition arising from imported goods sold at prices lower than their normal value. The latest revisions to the guidelines reflect Japan’s commitment to align its trade practices with international standards and respond to evolving market conditions. The Customs and Tariff Bureau (税関局, Zeikan-kyoku) has been actively updating these regulations to ensure transparency and fairness in trade practices. The previous guidelines were last amended in 2020, and the recent changes aim to clarify procedural aspects and enhance compliance measures for businesses involved in importing goods subject to anti-dumping duties. The updated guidelines are expected to streamline the application process for businesses and provide clearer criteria for determining whether goods are being sold at unfairly low prices.

1. Foreign Residents Already Operating a Business in Japan
If you are currently importing goods, it is essential to review your pricing strategies and ensure compliance with the updated anti-dumping duty guidelines. You may need to adjust your pricing to avoid penalties. Document all pricing structures and be prepared to provide evidence of normal value if challenged by the Customs and Tariff Bureau. Failure to comply could result in significant financial penalties and increased scrutiny of your import activities.

2. Foreign Nationals Planning to Establish a New Company
If you are considering starting a business that involves importing goods, familiarize yourself with the new guidelines before launching your operations. Ensure that your business plan includes a thorough analysis of potential anti-dumping duties that may apply to your products. This proactive approach can help you avoid unexpected costs and compliance issues once your business is operational.

3. Foreign Investors Who Are NOT Residents of Japan
For foreign investors looking to invest in Japanese companies that engage in import activities, understanding these guidelines is crucial. Conduct due diligence on potential investments to assess how these changes may impact the financial health and compliance risks of the businesses you are considering. Engaging local legal counsel with expertise in trade regulations can provide valuable insights and help mitigate risks associated with non-compliance.
