China Corrosion Inhibitors CVD Rates for 2024

The final China corrosion inhibitors CVD rates for the 2024 review period range from 18.64% to 48.45%. Importers and customs brokers must now align cash deposits, liquidation reserves, supplier records, and drawback calculations with the company-specific results.

Final 2024 Countervailing Duty Rates

The final results cover certain corrosion inhibitors from China under countervailing duty case C-570-123. The period of review runs from January 1 through December 31, 2024, and the final results carry an applicable date of October 2, 2026. Publication occurred on October 5, 2026.

Company-Specific Results

The final net subsidy rates are:

The 18.64% rate for Anhui Trust Chem also reflects its cross-owned relationship with Nanjing Trust Chem Co., Ltd. and Jiangsu Trust Chem Co., Ltd. The 48.45% rate for Nantong Botao Chemical reflects cross-ownership with Rugao Connect Chemical Co., Ltd., Rugao Jinling Chemical Co., Ltd., and Nantong Yutu Group Co., Ltd.

Connect Chemicals GMBH, Gold Chemical Limited, and Kanghua Chemical Co., Ltd., formerly Nantong Kanghua Chemical Co., Ltd., were not selected for individual examination. They received a review-specific average rate of 36.40%.

The spread between 18.64% and 48.45% is commercially significant. It reinforces why product origin alone is not enough to determine AD/CVD exposure. The producer, exporter, cross-owned affiliates, and applicable case combination must be validated against entry documentation. A mismatch between the commercial invoice, manufacturer declaration, entry summary, and internal supplier master can result in an incorrect deposit rate, understated liability, or an avoidable correction process.

The final calculation for Anhui Trust Chem changed after review comments, including adjustments involving an export trading company ratio and benefits associated with certain less-than-adequate-remuneration programs. Importers should therefore use the final rates rather than continuing to rely on preliminary review figures.

Cash Deposits, Assessments, and Liquidation Exposure

The final administrative review results affect both prospective cash deposits and the assessment of duties on entries from the reviewed period. These are related obligations, but they operate on different timelines and should be tracked separately.

Prospective Cash Deposit Requirements

For entries of subject merchandise on or after October 5, 2026, the reviewed companies generally receive the new cash deposit rates. Companies not covered by the review typically retain their existing deposit rates unless another determination changes them.

Importers should update broker instructions, trade compliance databases, landed-cost models, and enterprise resource planning systems with the new rates. The effective producer and exporter combination should be confirmed before entry transmission. A supplier name that is abbreviated, translated differently, or associated with a cross-owned affiliate can create uncertainty about the correct rate.

Cash deposits are estimates collected at entry. They do not necessarily represent the final duty liability for a shipment. Final liability is generally established through liquidation after the applicable administrative review and assessment process.

Assessment of 2024 Entries

The final rates also establish the basis for assessing countervailing duties on covered entries during the January 1 through December 31, 2024 review period. Assessment instructions are expected to be sent to U.S. Customs and Border Protection no earlier than 35 days after publication. Based on the October 5 publication date, that point falls on November 9, 2026.

That timing is not necessarily the liquidation date for every entry. Processing, instructions applicable to particular entry populations, and litigation can affect the schedule. If a court summons is filed and liquidation is enjoined, affected entries may remain unliquidated while judicial review proceeds.

Importers should reconcile their 2024 entry population before liquidation activity begins. Finance teams should compare deposits already paid with the final rate exposure and adjust reserves where appropriate. Compliance teams should also identify protests, post-summary corrections, prior disclosures, reconciliation entries, or other pending activity that could affect particular transactions.

Entry Controls and Duty Drawback Treatment

The final CVD rates create operational requirements beyond updating a percentage in an entry system. Effective compliance depends on connecting supplier identity, product scope, entry data, accounting reserves, and post-entry recovery programs.

Confirm the Producer and Exporter

Importers should validate the actual producer and exporter for every potentially affected shipment. Purchase orders and invoices may identify a trading company while omitting the manufacturer. Conversely, a supplier master may identify a corporate group without showing the legal entity that produced or exported the goods.

A defensible review should compare commercial invoices, packing lists, purchase orders, certificates, manufacturer affidavits, bills of lading, and entry records. Particular attention should be given to cross-owned affiliates and the former name of Kanghua Chemical Co., Ltd. Name normalization is important because minor differences in punctuation, corporate suffixes, or transliteration can conceal a substantive mismatch.

Product scope must also be evaluated independently from tariff classification. Harmonized Tariff Schedule classifications can support screening, but AD/CVD scope is generally controlled by the written product description. Classification alone should not be treated as conclusive.

Keep CVD Separate From Drawback-Eligible Duty

Countervailing duties and antidumping duties are not eligible for duty drawback under 19 U.S.C. 1677h. Importers and drawback filers should exclude those amounts from drawback claims, even when the associated merchandise is later exported or destroyed.

Ordinary customs duties paid on the same entry may still qualify for drawback when all applicable requirements are met. The accounting and claim logic should therefore distinguish among ordinary customs duty, antidumping duty, countervailing duty, and other charges rather than treating the total payment as a single recoverable amount.

This separation should exist at the entry-line level and flow through inventory, export, destruction, and claim records. If AD/CVD amounts are commingled with ordinary duties, a filer may overstate the refund request or spend substantial time reconstructing duty components during claim preparation and review.

Customs brokers supporting importer drawback programs should confirm that source data preserves each duty type. Importers should also align their reserve calculations with this treatment. An expected drawback recovery should not offset CVD exposure in the financial model because the CVD amount itself cannot be recovered through drawback.

Frequently Asked Questions

What Are the Final 2024 CVD Rates for Corrosion Inhibitors From China?

The final rates are 18.64% for Anhui Trust Chem Co., Ltd., 48.45% for Nantong Botao Chemical Co., Ltd., and 36.40% for Connect Chemicals GMBH, Gold Chemical Limited, and Kanghua Chemical Co., Ltd. Relevant cross-owned affiliates are generally covered through the company groupings established in the proceeding.

When Do the New Cash Deposit Rates Apply?

The new cash deposit rates apply to covered entries made on or after October 5, 2026, the publication date of the final results. Importers should verify the producer and exporter combination because non-reviewed companies generally continue under their previously established rates.

Do the Final Rates Apply to Entries Made in 2024?

The review covers entries during January 1 through December 31, 2024. The final results provide the basis for assessment instructions covering that period. The amount ultimately assessed may depend on the applicable company, entry population, liquidation instructions, and any judicial action affecting liquidation.

When Could CBP Receive Assessment Instructions?

Assessment instructions are expected no earlier than 35 days after October 5, 2026, which is November 9, 2026. This does not mean every affected entry will liquidate on that date. Importers should monitor entry status and preserve supporting records while liquidation remains pending.

Can Countervailing Duties Be Recovered Through Duty Drawback?

No. Countervailing and antidumping duties are not eligible for duty drawback. Ordinary customs duties paid on the same entries may still qualify if the merchandise, export or destruction activity, records, and claim satisfy the applicable drawback requirements.

What Should Importers Do Immediately?

Importers should update cash deposit rates, verify producer and exporter identities, review cross-owned affiliate names, calculate potential 2024 liquidation exposure, and adjust financial reserves. They should also ensure drawback calculations exclude all AD/CVD amounts while retaining any potentially eligible ordinary customs duties.
