U.S. Finalizes Antidumping Duties on Corrosion Inhibitors from China for 2023-2024

Estimated reading time: 5–7 minutes

The U.S. Department of Commerce has announced the final results of its administrative review regarding antidumping duties on certain corrosion inhibitors from China for the period of March 1, 2023, to February 29, 2024.

Background

The review was first published on January 2, 2025. It covers two main producers and exporters: Anhui Trust Chem Co., Ltd. (ATC), including Jiangsu Trust Chem Co., Ltd. and Nanjing Trust Chem Co., Ltd., treated as a single entity, and Nantong Botao Chemical Co., Ltd. (Botao). The review also included Gold Chemical Limited, a separate rate applicant.

The review period was delayed by 90 days, making July 8, 2025, the deadline for the final results.

Companies and Results

Commerce determined that the following estimated weighted-average dumping margins apply for entries during the review period:

China-Wide Entity

The China-wide entity was not under review since no parties requested a review and Commerce did not self-initiate. The rate for the China-wide entity remains 241.02 percent.

Changes and Analysis

Commerce considered comments from interested parties and made changes to the final results, explained in the detailed Issues and Decision Memorandum, available via the Antidumping and Countervailing Duty Centralized Electronic Service System (ACCESS) at https://access.trade.gov.

Assessment Rates

U.S. Customs and Border Protection (CBP) will assess antidumping duties on all relevant entries. Instructions for assessments will be issued no earlier than 35 days after this notice is published. If a timely summons is filed with the U.S. Court of International Trade, instructions may be delayed for up to 90 days.

Where companies did not report the entered value, CBP will use a per-unit duty assessment rate. If an importer’s rate is less than 0.5 percent, their entries will not be subject to duties.

Sales not reported by ATC or Botao will be assessed at the China-wide rate. Non-selected separate rate applicants will be assessed the average of the rates for ATC and Botao.

Cash Deposit Requirements

New cash deposit rates take effect for shipments entered, or withdrawn for consumption, after the publication date:

1. Reviewed companies receive the rates shown above.
2. Companies with previously established separate rates keep their last rate.
3. All Chinese exporters without a separate rate receive the China-wide rate of 241.02 percent.
4. Non-Chinese exporters without their own rate receive the rate of the Chinese supplier.

These requirements remain until further notice.

Reminders for Importers

Importers must file certificates regarding reimbursement of antidumping and/or countervailing duties. Failure to comply may result in double duties or duties increased by the amount of countervailing duties.

Administrative Protective Order

Parties under an administrative protective order must return or destroy proprietary information according to U.S. regulations. Failure to comply is a violation.

Official Notification

This notice is issued under U.S. law sections 751(a)(1) and 777(i)(1), and specific regulations.
