On October 20, 2026, the US Department of Commerce announced the initiation of anti-dumping and countervailing duty investigations into certain amine compounds originating from China. The petitions were filed by Evonik Corporation and Huntsman International LLC.
The case covers products under US HTS codes 2922.19.9690, 2921.29.0055 and 2934.99.9001. According to US statistics, imports of the products concerned from China totaled about $235 million in 2025, down from about $375 million in 2024.
The products are tertiary amine catalysts used in polyurethane systems, including flexible foam, rigid foam, coatings, adhesives and elastomers. Chinese products hold roughly a 30% share of the US market for the products, according to the report.
The alleged dumping margins range from 244.94% to 352.32%, and the alleged subsidy rate exceeds the 2% de minimis threshold. The investigations also include a rule of origin stipulating that amine compounds of Chinese origin remain subject to the case even after simple third-country processing such as blending or dilution.
Scope comments are due by November 9, 2026, with rebuttal comments due November 19, according to a Federal Register notice.
