**SUPPLEMENTARY INFORMATION:**
**Background**
On July 11, 2025, Commerce published in the *Federal Register* the *Preliminary Results* of this administrative review and invited comments from interested parties.

[^2]*See* Memorandum, “Certain Corrosion Inhibitors from the People's Republic of China: Respondent Selection,” dated June 17, 2024.
Due to a lapse in appropriations and Federal Government shutdown, on November 14, 2025, Commerce tolled all deadlines in administrative proceedings by 47 days. [^3] 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. [^4] On January 14, 2026, Commerce extended the deadline for the final results by an additional 53 days. [^5] Accordingly, the deadline for these final results is now March 9, 2026.

The products covered by the *Order* are corrosion inhibitors from China. For a full description of the scope of the *Order, see* the Issues and Decision Memorandum.
**Analysis of Comments Received**
All issues raised by interested parties in case briefs are addressed in the Issues and Decision Memorandum. The topics discussed and the issue raised by parties to which we responded in the Issues and Decision Memorandum are listed in the appendix to this notice.
**Changes Since the Preliminary Results**
Based on minor corrections received at verification, we made certain changes to the calculations for ATC, Botao, and the non-selected companies. However, no changes were made to the methodology used in the *Preliminary Results* . For a discussion of these changes, *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 of the subsidy programs found to be countervailable, we determine 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. [^8] For a full description of the methodology underlying Commerce's conclusions, including any determination that relied upon the use of adverse facts available, pursuant to section 776(a) and (b) of the Act, *see* the Issues and Decision Memorandum.
[^8]*See* sections 771(5)(B) and (D) of the Act regarding financial contribution; section 771(5)(E) of the Act regarding benefit; and section 771(5A) of the Act regarding specificity.
**Final Results of Review**
We find the following net countervailable subsidy rates exist for the period January 1, 2023, through December 31, 2023:
| Company | Subsidy rate |
| --- | --- |
| Anhui Trust Chem Co., Ltd | 44.65 |
| Nantong Botao Chemical Co., Ltd | 44.04 |

Commerce intends to issue assessment instructions to CBP no earlier than 35 days after 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 all non-reviewed firms, we will instruct CBP to continue to collect cash deposits of estimated countervailing duties at the all-others rate or the most recent company-specific rate applicable to the company, as appropriate. These cash deposit requirements, when imposed, shall remain in effect until further notice.
**Administrative Protective Order**
This notice also serves as a final reminder to parties subject to an administrative protective order (APO) of their responsibility concerning the disposition of proprietary information disclosed under APO in accordance with 19 CFR 351.305(a)(3). 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 subject to sanction.
