SUPPLEMENTARY INFORMATION:

Background

On June 24, 2005, Commerce published the antidumping duty order on chlorinated isocyanurates from China in the Federal Register .^[1] On July 25, 2025, pursuant to section 751(a)(1) of the Tariff Act of 1930, as amended (the Act), Commerce initiated an administrative review of the Order covering the period June 1, 2024, through May 31, 2025.^[2] The review was initiated covering three producers/exporters: Achlor Chemical Ltd. (Achlor), Heze Huayi Chemical Co., Ltd. (Heze Huayi) and Juancheng Kangtai Chemical Co., Ltd. (Kangtai).^[3]

Due to the lapse in appropriations and Federal Government shutdown, on November 14, 2025, Commerce tolled all deadlines in administrative proceedings by 47 days.^[4] Additionally, due to a backlog of documents that were electronically filed via Enforcement and Compliance's Antidumping and Countervailing Duty Centralized Electronic Service System (ACCESS) during the Federal Government shutdown, on November 24, 2025, Commerce tolled all deadlines in administrative proceedings by an additional 21 days.^[5] On April 24 and August 28, 2026, we extended the deadline to issue these preliminary results by 120 days to no later than September 8, 2026.^[6]

For a complete description of the events that occurred following the initiation of this administrative review, see the Preliminary Decision Memorandum.^[7] A list of topics discussed in the Preliminary Decision Memorandum is included as the appendix to this notice. The Preliminary Decision Memorandum is a public document and is on file electronically via ACCESS, which is available to registered users at access.trade.gov. In addition, a complete version of the Preliminary Decision Memorandum can be accessed directly at access.trade.gov/​frnotices.

Scope of the Order

The products covered by the Order are chlorinated isocyanurates, which are derivatives of cyanuric acid, described as chlorinated s-triazine triones. Chlorinated isocyanurates are currently classifiable under subheadings 2933.69.6015, 2933.69.6021, 2933.69.6050, 3808.40.50, 3808.50.40, and 3808.94.5000 of the Harmonized Tariff Schedule of the United States (HTSUS). For a complete description of the scope of the Order, see the Preliminary Decision Memorandum.

Partial Rescission of Review

As noted above, we initiated this review with respect to four companies.^[8] Pursuant to 19 CFR 351.213(d)(3), Commerce will rescind an administrative review when there are no reviewable suspended entries during the POR. Normally, upon completion of an administrative review, the suspended entries are liquidated at the antidumping duty assessment rate for the review period.^[9] Therefore, for an administrative review to be conducted, there must be a reviewable, suspended entry that Commerce can instruct U.S. Customs and Border Protection (CBP) to liquidate at the calculated antidumping duty assessment rate for the review period.^[10] On August 11, 2025, ( printed page 58632) Commerce placed on the record of the review CBP entry data for imports made during the POR under the HTSUS codes listed in the scope of the Order.^[11] On August 6, 2026, Commerce notified interested parties of its intent to rescind the review with respect to the company for which the CBP entry data query indicated to have had no reviewable, suspended entries of subject merchandise during the POR, Achlor.^[12] No parties commented on our intent to rescind. Accordingly, in the absence of any suspended entries of subject merchandise from this company during the POR, Commerce is rescinding this review with respect to Achlor in accordance with 19 CFR 351.213(d)(3). As a result, Heze Huayi and Kangtai are the only mandatory respondents with suspended entries under review during the POR.

The China-Wide Entity

Under Commerce's policy regarding the conditional review of the China-wide entity,^[13] the China-wide entity will not be under review unless a party specifically requests, or Commerce self-initiates, a review of the entity. Because no party requested a review of the China-wide entity, the entity is not under review, and the entity's rate ( i.e., 285.63 percent) is not subject to change.^[14]

Methodology

Commerce is conducting this administrative review in accordance with section 751(a)(1)(A) of the Act. Export prices have been calculated in accordance with section 772 of the Act. Because China is a non-market economy within the meaning of section 771(18) of the Act, normal value has been calculated in accordance with section 773(c) of the Act. For a full description of the methodology underlying our conclusions, see the Preliminary Decision Memorandum.

Separate Rates

In the Initiation Notice, we informed parties that firms for which the review was initiated that wished to qualify for separate rate status must complete, as appropriate, either a separate rate application or a separate rate certification.^[15] Commerce preliminarily determines that Heze Huayi and Kangtai are eligible to receive a separate rate in this review. For further discussion, see the Preliminary Decision Memorandum.

As stated above, Commerce preliminarily determines that Heze Huayi and Kangtai have established their eligibility for a separate rate, and that the following weighted-average dumping margins exist for the POR, June 1, 2024, through May 31, 2025:

Disclosure

Commerce intends to disclose the calculations performed in connection with these preliminary results to interested parties within five days of any public announcement or, if there is no public announcement, within five days of the date of publication of this notice in accordance with 19 CFR 351.224(b).

Public Comment

Case briefs or other written comments may be submitted to the Assistant Secretary for Enforcement and Compliance. Pursuant to 19 CFR 351.309(c)(1)(ii), we have modified the deadline for interested parties to submit case briefs to Commerce to no later than 21 days after the date of the publication of this notice.^[16] Rebuttal briefs, limited to issues raised in the case briefs, may be filed not later than five days after the date for filing case briefs.^[17] Interested parties who submit case briefs or rebuttal briefs in this proceeding must submit: (1) a table of contents listing each issue; and (2) a table of authorities.^[18] All briefs must be filed electronically using ACCESS. An electronically filed document must be received successfully in its entirety in ACCESS by 5:00 p.m. Eastern Time on the established deadline.

As provided under 19 CFR 351.309(c)(2)(iii) and (d)(2)(iii), we request that interested parties provide at the beginning of their briefs a public executive summary for each issue raised in their briefs.^[19] Further, we request that interested parties limit their executive summary of each issue to no more than 450 words, not including citations. We intend to use the executive summaries as the basis of the comment summaries included in the issues and decision memorandum that will accompany the final results in this administrative review. We request that interested parties include footnotes for relevant citations in the executive summary of each issue. Note that Commerce has amended certain of its requirements pertaining to the service of documents in 19 CFR 351.303(f).^[20]

Preliminary Results of Review

Pursuant to 19 CFR 351.310(c), interested parties who wish to request a hearing, limited to issues raised in the case and rebuttal briefs, must submit a written request to the Assistant Secretary for Enforcement and Compliance within 30 days after the publication of this notice. Requests should contain: (1) the party's name, address, and telephone number; (2) the number of participants, and whether any participant is a foreign national; and (3) a list of issues to be discussed. Issues raised in the hearing will be limited to those raised in the respective case briefs. If a request for a hearing is made, Commerce intends to hold the hearing at a time and date to be determined. Parties should confirm by telephone the date, time, and location of the hearing two days before the scheduled date. An electronically filed hearing request must be received successfully in its entirety by Commerce's electronic records system, ACCESS, by 5:00 p.m. Eastern Time within 30 days after the date of publication of this notice. ( printed page 58633)

Assessment Rates

Upon issuing the final results of this review, Commerce shall determine, and CBP shall assess, antidumping duties on all appropriate entries covered by this review.^[21] Commerce intends to issue assessment instructions to CBP no earlier than 35 days after date of publication of the final results of this review in the Federal Register . 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).

For each individually examined respondent in this review whose weighted-average dumping margin in the final results of review is not zero or de minimis ( i.e., less than 0.5 percent), Commerce intends to calculate importer-specific assessment rates for antidumping duties, in accordance with 19 CFR 351.212(b)(1).^[22] Where the respondent reported reliable entered values, Commerce intends to calculate importer-specific ad valorem assessment rates by aggregating the amount of dumping calculated for all U.S. sales to the importer and dividing this amount by the total entered value of the merchandise sold to the importer.^[23] Where the respondent did not report entered values, Commerce will calculate importer-specific assessment rates by dividing the amount of dumping for reviewed sales to the importer by the total quantity of those sales. Commerce will calculate an estimated ad valorem importer-specific assessment rate to determine whether the per-unit assessment rate is de minimis; however, Commerce will use the per-unit assessment rate where entered values were not reported.^[24] Where an importer-specific ad valorem assessment rate is not zero or de minimis, Commerce will instruct CBP to collect the appropriate duties at the time of liquidation. Where either the respondent's weighted average dumping margin is zero or de minimis, or an importer-specific ad valorem assessment rate is zero or de minimis, Commerce will instruct CBP to liquidate appropriate entries without regard to antidumping duties.^[25] For entries that were not reported in the U.S. sales database submitted by an exporter individually examined during this review, but that entered under the case number of that exporter ( i.e., at the individually-examined exporter's cash deposit rate), Commerce will instruct CBP to liquidate such entries at the China-wide rate.^[26]

Cash Deposit Requirements

The following cash deposit requirements will be effective upon publication of the final results of this administrative review for all shipments of the subject merchandise from China entered, or withdrawn from warehouse, for consumption on or after the publication date, as provided for by section 751(a)(2)(C) of the Act: (1) for the exporters listed above that have a separate rate, the cash deposit rate will be equal to the weighted-average dumping margin established in the final results of this review (except, if the rate is zero or de minimis within the meaning of 19 CFR 351.106(c)(1), then a cash deposit rate of zero will be established for that company); (2) for previously investigated or reviewed Chinese and non-Chinese exporters not listed above that received a separate rate in a prior segment of this proceeding, the cash deposit rate will continue to be the existing exporter-specific rate; (3) for all Chinese exporters of subject merchandise that have not been found to be entitled to a separate rate, the cash deposit rate will be the cash deposit rate established for the China-wide entity ( i.e., 285.63 percent); and (4) for all non-Chinese exporters of subject merchandise which have not received their own rate, the cash deposit rate will be the rate applicable to the Chinese exporter that supplied that non-Chinese exporter. These cash deposit requirements, when imposed, shall remain in effect until further notice.

Verification

As provided in section 782(i)(3) of the Act, Commerce intends to verify the information relied upon in its final results.

Final Results of Review

Unless extended, we intend to issue the final results of this administrative review, which will include the results of our analysis of issues raised in the case and rebuttal briefs, within 120 days of the date of publication of this notice in the Federal Register .^[27]

Notification to Importers

This notice also serves as a reminder to importers of their responsibility under 19 CFR 351.402(f)(2) to file a certificate regarding the reimbursement of antidumping and/or countervailing duties prior to liquidation of the relevant entries during this review period. Failure to comply with this requirement could result in Commerce's presumption that reimbursement of antidumping and/or countervailing duties occurred and the subsequent assessment of double antidumping duties, and/or an increase in the amount of antidumping duties by the amount of the countervailing duties.

Notification to Interested Parties

We are issuing and publishing these results in accordance with sections 751(a)(1) and 777(i)(1) of the Act, and 19 CFR 351.213 and 19 CFR 351.221(b)(4).
