Large-Diameter Graphite Electrodes From China Face Preliminary AD Duties and Retroactive Exposure

Large-diameter graphite electrodes from China now carry substantial preliminary antidumping exposure, including a 95.61% adjusted cash deposit rate and retroactive suspension of liquidation. Importers and customs brokers must quickly identify affected entries, confirm scope and origin, and align deposit operations with case A-570-220.

What the Preliminary AD Determination Establishes

The preliminary less-than-fair-value determination covers large-diameter graphite electrodes, or LDGE, from China during the period of investigation from July 1 through December 31, 2025. The finding means the merchandise is preliminarily considered to have been sold, or likely sold, in the United States at less than fair value.

The China-wide entity received an estimated weighted-average dumping margin of 98.79%. That margin was based on facts available with adverse inferences. After applicable subsidy offsets, the preliminary AD cash deposit rate is 95.61% while the relevant companion countervailing duty provisional measures remain in effect.

One China-Wide Rate Applies Across the Supply Base

No respondent qualified for a separate rate. As a result, all Chinese producers and exporters are treated as part of the China-wide entity, and no producer-exporter combination rates were calculated. Verification will not be conducted before the final determination.

This rate structure simplifies one part of broker programming but increases commercial exposure. Entry teams cannot rely on a supplier-specific rate merely because a manufacturer or exporter appears under a distinct legal name. Unless later instructions change the treatment, the China-wide rate applies throughout the covered Chinese supply base.

Third-country exporters also require careful handling. When an intermediary outside China exports subject merchandise, the applicable rate generally follows the China-wide entity that supplied the merchandise. Routing, invoicing, or reselling through another country does not ordinarily change the merchandise’s origin or eliminate AD exposure.

The final determination is due no later than 75 days after the September 22, 2026, signature date of the preliminary determination, unless the schedule is modified under the applicable process. Importers should treat the current rates as preliminary but operationally binding for affected entries.

Critical Circumstances Create Retroactive Entry Exposure

The preliminary affirmative critical-circumstances finding materially expands the financial impact of the case. Suspension of liquidation is not limited to entries made on or after the September 30, 2026, publication date. It reaches unliquidated entries entered, or withdrawn from warehouse for consumption, on or after the date 90 days before publication—generally July 2, 2026.

CBP is directed to suspend liquidation of qualifying entries from that retroactive period and require applicable cash deposits. Importers therefore may face deposit demands for merchandise that entered months before the preliminary determination became public.

Entry Date and Liquidation Status Drive the Review

The review population should be built using the legal entry or warehouse-withdrawal date, not the purchase-order date, vessel departure date, arrival date, invoice date, or payment date. Teams must then determine whether each entry remains unliquidated and whether the merchandise falls within the written scope.

Importers should reconcile at least four data sources:

• Entry summaries and line-level classification data
• Broker entry reports and liquidation status records
• Commercial invoices, packing lists, and technical specifications
• Supplier and manufacturing records supporting country of origin

Entries filed before the preliminary determination may not include the AD case number because the case had not yet reached the cash deposit stage. That does not necessarily prevent retroactive suspension. CBP may issue messages, bills, or correction requirements based on subsequent instructions.

The 95.61% rate reflects the preliminary adjustment for relevant subsidy offsets. If companion CVD provisional measures expire before the AD provisional measures, the AD cash deposit requirement generally becomes unadjusted. In that situation, the deposit may move to the 98.79% dumping margin, subject to the instructions then in effect. Deposit operations should therefore avoid hard-coding the adjusted rate without effective-date controls and a process for monitoring AD/CVD measure changes.

Scope, Classification, and Origin Require Technical Review

The covered merchandise generally consists of large-diameter graphite electrodes with a nominal or actual diameter exceeding 425 millimeters, or 16.7 inches. For merchandise using a pin joining system, the associated pin must generally have a diameter of at least 228.6 millimeters, or 9 inches, for the merchandise to satisfy the dimensional scope language.

The principal HTSUS classification identified for convenience is 8545.11.0020. Covered merchandise may also enter under 3801.10.5090 or 3801.90.0050. These tariff numbers are useful screening tools, but the written product description is dispositive. Classification alone cannot establish whether a product is in or out of scope.

Graphitization Determines Country of Origin

For this proceeding, country of origin is tied to where graphitization occurs. Importers should not assume that final machining, pin installation, coating, packaging, testing, or shipment through another country changes origin. A finished electrode exported from a third country may remain Chinese-origin merchandise when the graphitization process occurred in China.

This origin rule makes upstream production evidence particularly important. A defensible file may include production routing records, furnace or graphitization logs, mill certificates, batch records, manufacturer declarations, and purchase documents connecting the imported item to the facility where graphitization occurred.

The scope also contains published exclusions, including treatment for merchandise covered by the existing China small-diameter graphite electrodes AD order and certain TES graphite blocks. Exclusion decisions should be based on the complete technical criteria rather than product descriptions used in sales or purchasing systems.

Brokers should add dimensional fields and graphitization-country data to case-screening workflows wherever possible. Importers should likewise review parts described generically as graphite rods, blocks, electrode components, carbon products, or furnace consumables. Inconsistent descriptions can obscure covered merchandise and prevent automated screening from identifying an AD entry.

Operational Priorities for Importers and Customs Brokers

The immediate compliance task is to identify every potentially covered entry from the retroactive date forward. Importers should not limit the population to entries already declared under HTSUS 8545.11.0020. Screening should include alternative tariff provisions, free-text descriptions, supplier part numbers, product dimensions, graphitization origin, and third-country routing.

Each potentially affected line should be assigned a review status, such as in scope, excluded, pending technical documentation, or escalated for legal analysis. That structure allows compliance teams to distinguish genuine scope uncertainty from missing data and routine broker corrections.

Update Case Maps and Deposit Controls

Customs brokers should update AD/CVD case maps for A-570-220 and validate that the correct case treatment is connected to all relevant tariff classifications and product aliases. Because no exporter received a separate rate, supplier-specific logic should not override the China-wide treatment.

Deposit controls should separately store the 98.79% dumping margin and the current 95.61% adjusted cash deposit rate. The system should also retain the rate’s effective dates and the reason for the adjustment. This distinction is essential if the companion CVD provisional measures expire or if final instructions change the deposit calculation.

Importers and brokers should also:

• Review unliquidated entries from July 2, 2026, forward
• Confirm whether post-summary corrections or other entry updates are appropriate
• Estimate deposits and potential duty liability at the line level
• Establish reserves for retroactive and prospective exposure
• Monitor CBP messages, liquidation activity, and final determination timing
• Preserve scope, origin, valuation, and graphitization records
• Coordinate AD and CVD deposits without combining the two proceedings

The antidumping and countervailing duty cases are legally distinct. An entry may carry obligations under both, but case numbers, rates, provisional-measure periods, and critical-circumstances instructions must be administered separately. Combining them in a spreadsheet or broker rule can lead to missed deposits, duplicate calculations, or incorrect effective dates.

Frequently Asked Questions

What Is the Preliminary AD Cash Deposit Rate for LDGE From China?

The China-wide entity has a preliminary dumping margin of 98.79%. The current adjusted AD cash deposit rate is 95.61% after applicable subsidy offsets. If the companion CVD provisional measures expire before the AD provisional measures, the AD deposit generally becomes unadjusted, subject to the instructions in effect at that time.

How Far Back Does the AD Critical-Circumstances Finding Reach?

Suspension of liquidation applies to qualifying unliquidated entries entered, or withdrawn from warehouse for consumption, on or after the date 90 days before September 30, 2026. That date is generally July 2, 2026. Entry teams should use the formal consumption entry or withdrawal date when building the review population.

Do Any Chinese Exporters Have Separate AD Rates?

No respondent qualified for a separate rate at the preliminary stage. All Chinese producers and exporters are therefore treated as part of the China-wide entity, and no producer-exporter combination rates were calculated. Importers should not apply a company-specific rate unless later instructions expressly establish one.

Can Routing Through a Third Country Avoid the China AD Case?

Generally, no. Origin is based on where graphitization occurred, not simply the country of export, invoicing, final machining, or packaging. A third-country exporter typically uses the rate applicable to the China-wide entity that supplied the merchandise when the product remains Chinese origin.

Are HTSUS Numbers Enough to Determine Scope?

No. HTSUS 8545.11.0020 is the primary classification identified for convenience, while entries may also appear under 3801.10.5090 or 3801.90.0050. The written scope controls. Product diameter, pin dimensions, physical characteristics, exclusions, and graphitization origin must all be evaluated.

Is the AD Proceeding the Same as the Companion CVD Case?

No. The antidumping case A-570-220 addresses less-than-fair-value sales, while the companion CVD proceeding addresses countervailable subsidies. Although both may apply to the same entry, they have separate rates, case numbers, effective periods, and deposit instructions. Compliance systems should track them independently.
