Preliminary Findings on Corrosion Inhibitors from China by the U.S. Department of Commerce

Estimated reading time: 5–10 minutes

The U.S. Department of Commerce has announced its preliminary findings regarding certain corrosion inhibitors from the People’s Republic of China. This announcement, made on June 4, 2026, indicates that Chinese producers/exporters sold these inhibitors in the U.S. at less than their normal value.

Background Information

The review, which spans from March 1, 2024, to February 28, 2025, follows a decision to investigate 10 Chinese companies. The main focus was on two key companies: Anhui Trust Chem Co., Ltd. and Nantong Botao Chemical Co., Ltd. These companies were picked as the mandatory respondents for this review.

Methodology Used

To determine the sale prices, the Department of Commerce used specific methods outlined in the U.S. trade laws. Because China is considered a non-market economy, the normal value of these products was evaluated differently, using section 773(c) of the Tariff Act of 1930.

Findings of the Review

The preliminary findings showed that Anhui Trust Chem Co., Ltd. and Nantong Botao Chemical Co., Ltd. had dumping margins of 61.51% and 86.96%, respectively. Other companies involved in this review, Gold Chemical Limited and Kanghua Chemical Co., Ltd., were assigned a dumping margin of 73.75%.

Separate Rates Determination

The investigation also identified several companies eligible for a separate rate, distinct from those under the general Chinese entity rate. This includes the two main companies investigated and two other companies that were not individually examined but still eligible for a separate status.

China-Wide Entity

Six companies reviewed failed to claim separate status and are thus part of the China-wide entity. Consequently, these companies are subject to a 241.02% duty rate as determined by the department’s policy.

Future Steps and Public Involvement

The U.S. Department of Commerce will provide a chance for interested parties to comment on these preliminary results. They have set a timeline for public comments and planned a verification process for information used in the final results.

Next Actions for Importers

Importers of the affected products must comply with filing requirements concerning antidumping and/or countervailing duties. This will involve filing a certificate regarding the reimbursement of duties before entry liquidation.

In summary, the preliminary results indicate significant dumping margins for corrosion inhibitors from China sold in the U.S. The Department intends to proceed with verification and review public comments before finalizing the results.
