SUPPLEMENTARY INFORMATION:

Background

On May 13, 2026, Commerce published the Preliminary Results of the 2023 administrative review of the countervailing duty order on chlorinated isocyanurates from China.^[1] This review covers one company, Heze Huayi. On July 29, 2026, and October 29, 2026, Commerce extended the deadline for issuing the final results.^[2] The deadline for the final results of review is November 9, 2026.

From August 3 to 7, 2026, we conducted verification of the questionnaire responses of Heze Huayi.^[3] We invited interested parties to comment on the Preliminary Results.^[4] On September 28, 2026, we received a timely case brief from Bio-Lab, Inc., Innovative Water Care, LLC, and Occidental Chemical Corporation (collectively, the petitioners).^[5] On October 6, 2026, we received a timely rebuttal brief from Heze Huayi.^[6]

For a detailed description of the events that occurred since the Preliminary Results, see the Issues and Decision Memorandum.^[7] The Issues and Decision Memorandum is a public document and is on file electronically via Enforcement and Compliance's Antidumping and Countervailing Duty Centralized Electronic Service System (ACCESS), which is available to registered users at access.trade.gov. In addition, a complete version of the Issues and Decision Memorandum can be accessed directly at access.trade.gov/​frnotices.

Scope of the Order ^[8]

The product covered by the Order is chlorinated isocyanurates from China. For a complete description of the scope of the Order, see the Issues and Decision Memorandum.

Methodology

Commerce conducted this administrative review in accordance with section 751(a)(1)(A) of the Tariff Act of 1930, as amended (the Act). For each subsidy program found to be countervailable, Commerce finds that there is a subsidy, i.e., a government-provided financial contribution that gives rise to a benefit to the recipient, and that the subsidy is specific.^[9] For a full description of the methodology underlying all of Commerce's conclusions, see the Issues and Decision Memorandum.

Analysis of Comments Received

Commerce addressed all issues raised in interested parties' case and rebuttal briefs in the Issues and Decision Memorandum. A list of the issues that parties raised, to which we responded in the Issues and Decision Memorandum, is attached as an ( printed page 73205) appendix to this notice. Based on our analysis of the comments received from interested parties, we made no changes to the Preliminary Results.

Final Results of Administrative Review

Commerce determined that the following net countervailable subsidy rate exists for the period January 1, 2023, through December 31, 2023:

Disclosure

Normally, Commerce will disclose to the parties in a proceeding the calculations performed in connection with the final results of a review within five days of any public announcement or, if there is no public announcement, within five days of the date of publication of the notice of final results in the Federal Register , in accordance with 19 CFR 351.224(b). However, as we have made no changes to the Preliminary Results, there are no new calculations to disclose.

Assessment Rates

Pursuant to section 751(a)(2)(C) of the Act and 19 CFR 351.212(b)(2), Commerce will determine, and U.S. Customs and Border Protection (CBP) shall assess, countervailing duties on all appropriate entries of subject merchandise covered by this review for Heze Huayi at the applicable ad valorem assessment rate listed above. We intend to issue assessment instructions to CBP no earlier than 35 days after the date of publication of these final results of review. If a timely summons is filed at the U.S. Court of International Trade, the assessment instructions will direct CBP not to liquidate relevant entries until the time for parties to file a request for a statutory injunction has expired ( i.e., within 90 days of publication).

Cash Deposit Requirements

In accordance with section 751(a)(2)(C) of the Act and 19 CFR 351.107(e), Commerce intends to instruct CBP to collect cash deposits of estimated countervailing duties in the amounts shown above on shipments of subject merchandise entered, or withdrawn from warehouse, for consumption on or after the date of publication of the final results of this administrative review, as follows: (1) the cash deposit rate for Heze Huayi will be equal to the company-specific estimated individual countervailable subsidy rate determined in the final results of this review; (2) if both the producer and exporter of the subject merchandise have company-specific estimated subsidy rates assigned, and their rates differ, then the applicable cash deposit rate will be the higher of these two rates; (3) if either the producer or the exporter, but not both, of the subject merchandise has a company-specific estimated subsidy rate assigned, the applicable cash deposit rate will be that company's company-specific rate; and (4) the cash deposit rate for all other producers and exporters will be continue to be 10.81 percent, the all-others subsidy rate established in the investigation.^[10] These cash deposit requirements, effective upon publication of the final results of this review, shall remain in effect until further notice.

Timely written notification of the return or destruction of APO materials or conversion to judicial protective order is hereby requested. Failure to comply with the regulations and terms of an APO is a sanctionable violation.
