Japan Extends Taxable Antidumping Period for Potassium Hydroxide From South Korea, China

Japan's Ministry of Finance extended antidumping duties on potassium hydroxide from South Korea and China to Aug. 12, 2026, it said in an Aug. 10 notice. The ministry determined that the expiration of the duties would have resulted in injury to the domestic potassium hydroxide industry, resulting in the extension of the duties, which were set to expire Aug. 8. The duties were originally implemented in 2016 and exclude hydroxide from Hong Kong and Macao. The dumping margin sits at 49.5% for potassium hydroxide from South Korea and at 73.7% for the Chinese goods.
