The preliminary CBS countervailing duty rate on imports from China creates an immediate and unusually significant compliance exposure. With a 107.57% ad valorem rate and an affirmative critical circumstances finding, importers must evaluate both future shipments and unliquidated entries reaching back to July 2026.
What the Preliminary CBS Determination Changes
A Uniform 107.57% Countervailing Duty Rate
The U.S. Department of Commerce issued a preliminary affirmative countervailing duty determination covering N-Cyclohexylbenzothiazole-2-Sulfenamide, commonly known as CBS, from China. The investigation is identified as case C-570-235 and covers a period of investigation from January 1 through December 31, 2025.
Commerce assigned a preliminary subsidy rate of 107.57% ad valorem to the mandatory respondents, Shandong Derek New Materials Co., Ltd. and Shandong Yanggu Huatai International Co., Ltd. The same rate applies to several companies treated as non-responsive, including Alchemy Trading Shanghai Limited, Kemai Chemical Company Limited, SAIC Motor Corporation Limited, Shandong Sunsine Chemical Co., Ltd., and Yingtai International Trading Co.
The all-others rate is also 107.57%. As a result, importers generally cannot reduce exposure merely by sourcing covered Chinese CBS from a supplier that was not individually examined. Unless the final determination changes the rate or scope, all covered producer and exporter combinations face the same preliminary deposit requirement.
Critical Circumstances Create Retroactive Exposure
The affirmative critical circumstances finding is especially important. Suspension of liquidation and cash deposit requirements apply to covered entries made on or after October 8, 2026. They also generally reach back 90 days to unliquidated entries made on or after approximately July 10, 2026.
Importers should treat July 10 as the working review date while reconciling their entry population against operative U.S. Customs and Border Protection instructions. Entry date, liquidation status, product scope, country of origin, and producer-exporter data can all affect the final exposure analysis.
The final countervailing duty determination is aligned with the companion antidumping investigation and is currently expected by January 11, 2027, unless the schedule is postponed. Interested parties generally face a November 9, 2026 deadline for case briefs because the 30th day after publication falls on a Saturday. Rebuttal briefs generally follow five days later.
How Importers Should Respond to the 107.57% Rate
Build a Complete Entry Population
The first operational priority is identifying every potentially covered CBS entry from China made on or after July 10, 2026. Importers should not rely exclusively on product descriptions from purchase orders or commercial invoices. Reviews should incorporate entry summaries, tariff classifications, supplier names, manufacturer identities, technical specifications, chemical identifiers, and internal product master data.
CBS is a delayed-action rubber vulcanization accelerator used in products such as tires, hoses, belts, and other rubber applications. Importers purchasing chemicals under internal abbreviations, proprietary descriptions, blends, or broader product families may therefore need technical personnel to help determine whether merchandise falls within the investigation's written scope.
The written scope generally controls over tariff classification. Harmonized Tariff Schedule numbers can help locate entries, but they should not be treated as conclusive when product chemistry and scope language point in another direction. Customs brokers, trade counsel, compliance teams, procurement personnel, and laboratory or product specialists may all need to participate in the review.
Quantify Cash Deposit and Liquidation Risk
A 107.57% ad valorem cash deposit can exceed the entered value of the merchandise. Importers should model the impact at the line level rather than applying a broad percentage to annual purchasing forecasts. The analysis should account for customs value, valuation additions, foreign inland freight treatment, assists, related-party pricing, and any other factor that changes entered value.
Cash deposits are not necessarily the final liability. They secure estimated AD/CVD obligations while liquidation remains suspended. Final duty liability can increase or decrease based on the investigation, administrative reviews, court proceedings, and final liquidation instructions. Importers therefore need to distinguish cash flow exposure from ultimate duty expense.
Finance teams should also evaluate whether purchase contracts allocate responsibility for newly imposed duties. Incoterms alone may not resolve the commercial allocation between buyer and seller. Customs law generally holds the importer of record responsible to the U.S. government, even when a supplier has separately agreed to reimburse the cost.
For future shipments, landed cost models should reflect the 107.57% CVD deposit and any separate antidumping deposit that may arise from the companion case. Companies should also review bond sufficiency, broker funding procedures, payment timing, inventory margins, and supplier diversification options.
Duty Drawback and Broader Compliance Implications
AD/CVD Payments Must Be Segregated From Drawback
Countervailing and antidumping duties are not eligible for duty drawback under 19 U.S.C. 1677h. Exporting or destroying merchandise does not convert an AD/CVD cash deposit into a refundable drawback amount. This restriction applies even when the underlying imported merchandise otherwise supports a valid unused merchandise, manufacturing, or rejected merchandise drawback theory.
Ordinary customs duties, taxes, and eligible fees paid on the same entry may still qualify for drawback when all applicable statutory and procedural requirements are met. Drawback calculations must therefore separate ordinary duty from antidumping and countervailing duty amounts at the entry-line level.
This segregation is important because a single entry line can contain multiple categories of government charges. If a drawback system treats the entire payment as eligible duty, the resulting claim can overstate the refund. Conversely, excluding the full entry merely because it contains AD/CVD can cause an importer to abandon recoverable ordinary duties.
Coordinate Import Compliance With Refund Strategy
Importers should preserve the underlying entry data even when the current CBS CVD deposit cannot be recovered through drawback. A complete record remains necessary for liquidation monitoring, accounting accruals, protests or other available remedies, supplier discussions, and reconciliation with broker statements.
For drawback purposes, compliance teams should maintain distinct data fields for ordinary customs duty, merchandise processing fees, harbor maintenance fees where relevant, antidumping deposits, and countervailing deposits. The drawback claim should include only legally eligible amounts and should continue to satisfy requirements for export evidence, inventory matching, substitution where permitted, and claim timing.
Customs brokers serving CBS importers have an opportunity to connect the immediate CVD review with a broader duty recovery assessment. The high deposit rate may dominate management attention, but ordinary duties paid on exported or destroyed merchandise can still represent a material recovery opportunity. That analysis should remain separate from any expectation that the 107.57% CVD amount itself can be refunded through drawback.
The determination also reinforces the need for connected trade data. Classification, origin, producer identity, entry date, liquidation status, scope analysis, deposit type, and drawback eligibility should not reside in disconnected spreadsheets. Consistent data governance allows compliance leaders to quantify exposure quickly when a trade remedy case introduces retroactive liability.
- On October 8, 2026, the U.S. Department of Commerce published its preliminary affirmative countervailing duty determination on N-Cyclohexylbenzothiazole-2-Sulfenamide (CBS) from China (case C-570-235, 91 FR 64337), assigning a uniform 107.57% ad valorem subsidy rate based on adverse facts available to mandatory respondents Shandong Derek New Materials Co., Ltd. and Shandong Yanggu Huatai International Co., Ltd., several non-responsive companies (including Alchemy Trading Shanghai Limited, Kemai Chemical Company Limited, SAIC Motor Corporation Limited, Shandong Sunsine Chemical Co., Ltd., and Yingtai International Trading Co.), and all others. The period of investigation was January 1 through December 31, 2025. Petitioner LANXESS Corporation.
- Commerce also made a preliminary affirmative critical circumstances finding, so suspension of liquidation and cash deposit requirements apply retroactively 90 days prior to publication (covering unliquidated entries from approximately July 8, 2026). Cash deposits at the 107.57% rate are required going forward. The CVD final determination is aligned with the companion antidumping investigation, currently scheduled around January 11, 2027, unless postponed.
- On September 24, 2026, Commerce postponed the preliminary antidumping determination (A-570-232) to no later than October 28, 2026, following a timely request from LANXESS to allow additional time for analysis, including potential export subsidies from the CVD case.
- Chinese chemical industry outlets (ChemNet and others) reported the determination on October 7-8, 2026, emphasizing the uniform high rate, retroactive collection, and CBS's role as a key delayed-action rubber vulcanization accelerator used in tires, hoses, belts, and other products. China is a major global producer and exporter of CBS. No significant practitioner discussions were identified on X.
Frequently Asked Questions
What Merchandise Is Covered by the CBS Investigation?
The investigation covers N-Cyclohexylbenzothiazole-2-Sulfenamide from China, commonly called CBS. It is generally used as a delayed-action accelerator in rubber vulcanization. Importers should analyze the written scope and product chemistry rather than relying solely on tariff classification or a commercial product name.
When Does the 107.57% Cash Deposit Apply?
The preliminary cash deposit requirement applies to covered entries made on or after October 8, 2026. Because Commerce preliminarily found critical circumstances, suspension of liquidation also generally reaches unliquidated entries made approximately 90 days earlier. Importers should review entries made on or after July 10, 2026, and confirm treatment against CBP implementation instructions.
Does the Rate Apply to Suppliers Not Named in the Case?
Yes, in general. The preliminary all-others rate is also 107.57%. Covered CBS from China can therefore remain subject to the same rate even when the producer or exporter is not one of the specifically listed companies.
Can the Final Countervailing Duty Rate Change?
Yes. A preliminary rate is not necessarily the final rate. Commerce may revise its analysis before the final determination, and subsequent administrative or judicial proceedings can affect ultimate liability. Importers should nevertheless fund the required preliminary deposits and maintain appropriate accounting reserves.
Can Importers Recover the CVD Through Duty Drawback?
No. Antidumping and countervailing duties are not eligible for drawback. However, ordinary customs duties paid on the same entry may remain eligible when the merchandise is subsequently exported or destroyed and the transaction satisfies the applicable drawback requirements.
Could Antidumping Duties Apply in Addition to the CVD Rate?
Yes. CBS from China is also subject to a companion antidumping investigation. If an affirmative antidumping determination results in a cash deposit requirement, importers may have to deposit both antidumping and countervailing duties. Landed cost models should account for the possibility of cumulative trade remedy exposure.
How Stable Software Can Help
Support Broker-Led Duty Recovery
The 107.57% CBS countervailing duty cannot be recovered through drawback, but eligible ordinary duties paid on the same entries should not be overlooked. Accurate separation of duty categories is essential to avoid claiming prohibited AD/CVD amounts or excluding otherwise recoverable customs duties.
DrawbackAI is flat-license duty drawback software that U.S. customs brokers can white-label for importer clients and use to file claims under their own filer code. Stable Software charges a flat software license and never takes a percentage of the importer’s refund. Brokers evaluating CBS entry data can use the broader review as an opportunity to identify lawful duty recovery while maintaining a clear boundary between eligible ordinary duties and ineligible AD/CVD payments.
