Category: Regulatory Update
Background & Context
The Japanese government has been actively monitoring the import of Bisphenol A (BPA), a chemical compound widely used in the production of plastics and resins. The current legal framework governing this issue falls under the Customs Tariff Act (Kanzei-hō) of 1981, which allows for the imposition of anti-dumping duties to protect domestic industries from unfair competition. The Ministry of Finance (Zaimu-shō) initiated the investigation due to concerns that imports from South Korea, Taiwan, and the Pescadores, Kinmen, and Matsu Islands were being sold at prices below their normal value, potentially harming local manufacturers. The investigation period has now been extended, allowing for a more thorough assessment of the market conditions and pricing strategies of these imports. This extension is part of Japan’s ongoing efforts to ensure fair trade practices and uphold the integrity of its domestic market. The original investigation was launched in early 2026, and with this extension, stakeholders are encouraged to stay informed about the developments as the Ministry of Finance continues its inquiries.How This Affects Your Business in Japan
