**SUPPLEMENTARY INFORMATION:**
**Background**
On October 3, 2025, Commerce published the *Preliminary Results* in the *Federal Register* and invited interested parties to comment. [^1]

Due to the lapse in appropriations and Federal Government shutdown, on November 14, 2025, Commerce tolled all deadlines in administrative proceedings by 47 days. [^2] 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. [^3] Accordingly, the deadline for this final determination is now April 7, 2026.
[^2]*See* Memorandum, “Deadlines Affected by the Shutdown of the Federal Government,” dated November 14, 2025.
[^3]*See* Memorandum, “Tolling of all Case Deadlines,” dated November 24, 2025.

**Analysis of Comments Received**
The issues raised in the case and rebuttal briefs submitted by interested parties in this administrative review are addressed in the Issues and Decision Memorandum. A list of the issues addressed in the Issues and Decision Memorandum is attached to this notice as the Appendix.
**Changes Since the Preliminary Results**
Based on a review of the record and our analysis of the comments received from interested parties regarding the *Preliminary Results,* Commerce made certain changes to the preliminary weighted-average dumping margin calculations for mandatory respondents Heze Huayi Chemical Co. Ltd. and Juancheng Kangtai Chemical Co. Ltd. for the final results. For further details on the changes made since the *Preliminary Results, see* the Issues and Decision Memorandum.
**China-Wide Entity**
As noted in the *Preliminary Results,* in accordance with Commerce's policy, the China-wide entity is not under review because no party specifically requested, and Commerce did not self-initiate, a review of the China-wide entity. [^6] Thus, the China-wide entity's dumping margin, *i.e.,* 285.63 percent, is not subject to change as a result of this administrative review.
[^6]*See Preliminary Results* at 7.
**Final Results of Administrative Review**
Commerce determines the following estimated weighted-average dumping margins for the companies listed below for the period June 1, 2023, through May 31, 2024:
| Producer/exporter | Weighted-average dumping |
| --- | --- |
| Heze Huayi Chemical Co. Ltd | 39.87 |
| Juancheng Kangtai Chemical Co. Ltd | 30.24 |
**Disclosure**
Commerce intends to disclose the calculations performed for these final results of review within five days of the date of publication of this notice in the *Federal Register* ,in accordance with 19 CFR 351.224(b).
**Assessment Rates**
Pursuant to section 751(a)(2)(C) of the Tariff Act of 1930, as amended (the Act) and 19 CFR 351.212(b), Commerce shall determine, and U.S. Customs and Border Protection (CBP) shall assess, antidumping duties on all appropriate entries of subject merchandise in accordance with the final results of this review. For any individually examined respondents whose weighted-average dumping margin is above *de minimis,* we calculated importer-specific *ad valorem* duty assessment rates based on the ratio of the total amount of antidumping duties calculated for the examined sales to the total entered value of the examined sales to that importer, and we will instruct CBP to assess antidumping duties on all appropriate entries covered by this. Where either the respondent's weighted-average dumping margin is zero or *de minimis* within the meaning of 19 CFR 351.106(c)(1), or an importer-specific assessment rate is zero or *de minimis,* we will instruct CBP to liquidate the appropriate entries without regard to antidumping duties.
Commerce intends to issue assessment instructions to CBP no earlier than 35 days after the date of publication of the final results of this administrative 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).
**Cash Deposit Requirements**
The following cash deposit requirements will be effective for all shipments of subject merchandise entered, or withdrawn from warehouse, for consumption on or after the publication date of the final results of this administrative review in the *Federal Register* , as provided for by section 751(a)(2) of the Act: (1) the cash deposit rate for companies subject to this review will be the rates established in these final results of the review; (2) for merchandise exported by producers or exporters not covered in this review but covered in a prior segment of the proceeding, the cash deposit rate will continue to be the company-specific rate published for the most recent period; (3) for all China exporters of subject merchandise that do not have a separate rate, the cash deposit rate will be equal to the weighted-average dumping margin assigned to the China-wide entity ( *i.e.* 285.63 percent); (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.
**Administrative Protective Order (APO)**
This notice also serves as a final reminder to parties subject to an APO of their responsibility concerning the return or destruction of proprietary information disclosed under APO in accordance with 19 CFR 351.305, which continues to govern business proprietary information in this segment of the proceeding. 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 violation which is subject to sanction.
**Notification to Importers**
This notice serves as a final reminder to importers of their responsibility under 19 CFR 351.402(f)(2) to file a certificate regarding the reimbursement of antidumping 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 duties has occurred and the subsequent assessment of double antidumping duties.
**Notification to Interested Parties**
This determination is issued and published pursuant to sections 751(a)(1) and 777(i)(1) of the Act, and 19 CFR 351.221.
Dated: March 6, 2026.
