China's Cheap Pool Chemicals Hit with Delayed US Duties
Published Date: 3/11/2026
Notice
Summary
The U.S. Department of Commerce found that chlorinated isocyanurates from China were sold in the U.S. at unfairly low prices between June 2023 and May 2024. This means importers might have to pay extra duties to level the playing field. The final decision, delayed by government shutdowns, takes effect March 11, 2026, with some deadlines pushed to April 7, 2026.
Analyzed Economic Effects
4 provisions identified: 0 benefits, 4 costs, 0 mixed.
Importers may owe large antidumping duties
The Department of Commerce found chlorinated isocyanurates from China were sold below normal value for June 1, 2023 through May 31, 2024. Commerce assigned final weighted-average dumping margins of 39.87% for Heze Huayi Chemical Co. Ltd, 30.24% for Juancheng Kangtai Chemical Co. Ltd, and a China‑wide margin of 285.63%, meaning U.S. importers of these products may be required to pay additional antidumping duties based on those rates.
Cash deposit rates required on new entries
For shipments entered or withdrawn for consumption on or after the publication date of these final results, cash deposit requirements apply. The cash deposit rate for companies subject to this review will be the rates from these final results (39.87% and 30.24% for the two named companies); for exporters without a separate rate the China‑wide rate of 285.63% applies, and other specific rules in the notice govern rates for exporters not examined in this review.
File reimbursement certificate or risk double duties
Importers must file a certificate about reimbursement of antidumping duties prior to liquidation 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 on the relevant entries.
Timing of duty assessment and liquidation holds
Commerce will instruct U.S. Customs and Border Protection (CBP) to assess antidumping duties based on the final results; Commerce intends to issue assessment instructions no earlier than 35 days after the Federal Register publication. If a timely summons is filed at the U.S. Court of International Trade, instructions will direct CBP not to liquidate the relevant entries until the time for requesting a statutory injunction has expired (i.e., within 90 days of publication).
