China's Pool Shock Faces U.S. Dumping Duties in New Review
Published Date: 9/16/2026
Notice
Summary
The U.S. Department of Commerce found that some Chinese companies sold chlorinated isocyanurates in the U.S. for less than fair value from June 2024 to May 2025. This means antidumping duties might apply to those products, affecting importers and Chinese exporters. The review deadline was extended due to government shutdowns, with preliminary results announced in September 2026.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 3 costs, 0 mixed.
Preliminary Dumping Margins Announced
The Department of Commerce preliminarily found that chlorinated isocyanurates from China were sold at less than normal value for the period June 1, 2024 through May 31, 2025. Commerce preliminarily calculated weighted-average dumping margins of 90.65 percent for Heze Huayi Chemical Co. Ltd. and 72.63 percent for Juancheng Kangtai Chemical Co. Ltd.; Commerce will determine final rates and U.S. Customs and Border Protection (CBP) will assess duties on entries covered by this review.
China-Wide Rate and Cash Deposit Rules
Commerce states that the China-wide rate remains 285.63 percent and that, upon publication of the final results, cash deposit requirements will apply to shipments entered or withdrawn from warehouse for consumption on or after the publication date. Exporters found to have a separate rate will have cash deposit rates equal to the weighted-average dumping margin established in the final results; Chinese exporters without separate-rate status will have cash deposit rates equal to the China-wide rate of 285.63 percent; non-Chinese exporters without their own rate will be assigned the rate of the Chinese exporter that supplied them.
Importer Reimbursement Certificate Requirement
Importers must file a certificate about reimbursement of antidumping and/or countervailing duties prior to liquidation of the relevant entries for this review period, as required by 19 CFR 351.402(f)(2). If an importer fails to file this certificate, Commerce may presume reimbursement occurred and assess double antidumping duties and/or increase antidumping duties by the amount of countervailing duties.
