Large Diameter Welded Pipe From Türkiye: Final 2024–2025 AD Review Rates

Importers of large diameter welded pipe from Türkiye must now account for final antidumping duty rates affecting cash deposits, entry processing, and eventual liquidation. The September 25, 2026, changes require coordinated updates across customs brokerage systems, product databases, supplier records, and post-entry compliance workflows.

Final AD Review Results for Turkish Large Diameter Welded Pipe

The final administrative review covers antidumping case A-489-833 and the period from May 1, 2024, through April 30, 2025. The final weighted-average dumping margins remain unchanged from the preliminary results because no parties submitted comments challenging the preliminary calculations.

These results are significant for two distinct groups of transactions: entries made during the period of review, which may be subject to final assessment, and new entries made on or after September 25, 2026, which are subject to the updated cash deposit instructions.

Published Company-Specific Rates

The final rates are:

• HDM Celik Boru Sanayi Ve Ticaret A.S.: 1.89%
• HDM Spiral Kaynakli Celik Boru A.S. / HDM Spirally Welded Steel Pipe Inc.: 1.89%
• Cimtas Boru Imalatiral Ticaret Ltd: 1.89%
• All-others rate: 1.57%

HDM Celik was the mandatory respondent examined during the review. The 1.89% rate also applies to the identified HDM affiliate. Cimtas was not selected for individual examination but received the review rate of 1.89%.

Why the Rate Categories Matter

The 1.89% reviewed-company rate should not be treated as a countrywide rate for every shipment of Turkish large diameter welded pipe. Companies previously reviewed or investigated but not covered by this review generally retain their most recent company-specific cash deposit rate. The 1.57% all-others rate continues to apply when no applicable exporter or producer rate is available.

Importers and brokers should therefore validate both the exporter and producer before assigning an antidumping rate. Similar company names, affiliate relationships, and inconsistent supplier master data can produce incorrect deposits even when the merchandise is properly classified.

Applying the New Antidumping Cash Deposit Rates

The revised 1.89% cash deposit requirement became effective for covered merchandise entered, or withdrawn from warehouse for consumption, on or after September 25, 2026. Entry teams should apply the effective date according to the consumption entry event rather than the purchase order date, export date, vessel departure, or arrival date.

Cash deposits are provisional amounts collected while the ultimate antidumping duty liability remains subject to administrative review and liquidation. A deposit rate therefore should not be presented internally as the final duty cost for an entry.

Exporter and Producer Rate Hierarchy

Rate selection generally follows a defined hierarchy under the final cash deposit instructions:

1. A reviewed exporter or producer covered by the final results receives the applicable 1.89% rate.
2. A previously reviewed or investigated company not covered by the current review typically retains its latest company-specific rate.
3. If the exporter has no applicable rate but the producer does, the producer’s rate applies.
4. If neither party has an applicable company-specific rate, the 1.57% all-others rate generally applies.

This hierarchy makes manufacturer identification essential. A broker relying only on the commercial invoice seller may overlook the producer whose rate controls the deposit requirement.

Operational Controls for Entry Processing

Customs and deposit operations should update case-rate tables with an effective date of September 25, 2026, while preserving historical rates for earlier entries. Overwriting a prior rate without date logic can affect reconciliation, post-entry analysis, and audit trails.

Recommended controls include matching legal entities against approved manufacturer records, requiring producer data before entry release, and generating exceptions when the declared exporter-producer combination lacks a mapped rate. Teams should also test automated calculations to confirm that the antidumping deposit is applied to the appropriate entered value and kept separate from ordinary customs duties, fees, and other trade remedies.

Assessment, Liquidation, and Importer Compliance

Final assessment determines the antidumping duties owed on entries made during the May 1, 2024, through April 30, 2025, period of review. Commerce intends to issue assessment instructions to U.S. Customs and Border Protection no earlier than 35 days after the September 25 publication date. Importers should use that interval to reconcile entries, confirm manufacturer data, and identify unresolved reimbursement certification issues.

For HDM entries, assessment may be based on importer-specific ad valorem rates calculated using entered value. The amount assessed at liquidation may therefore differ from the cash deposit originally paid.

Entries With No Knowledge of U.S. Destination

A special rule applies when HDM did not know at the time of sale that the merchandise was ultimately destined for the United States. Unreviewed entries in that situation are generally liquidated at the 1.57% all-others rate when no rate is available for an intermediate company involved in the transaction.

This treatment makes transaction-chain visibility particularly important. Importers should retain purchase orders, invoices, sales communications, shipping instructions, and intermediary records that identify when the U.S. destination became known. Brokers should not infer producer knowledge solely from the port of export or final bill of lading.

Reimbursement Certifications and Drawback Limitations

Under 19 CFR 351.402(f)(2), importers must generally provide the required certification concerning reimbursement of antidumping duties before liquidation. Failure to certify can create a presumption that the exporter or another party reimbursed the importer, potentially resulting in double assessment.

The certification requirement should be tracked at the entry level rather than handled as a general annual task. Responsibility should be assigned across customs, legal, accounts payable, and broker management teams well before liquidation.

Importers should also avoid assuming that antidumping cash deposits are recoverable through drawback. Antidumping duties are generally outside the drawback framework under 19 U.S.C. 1677h and 19 CFR 190.3. Financial models should therefore separate ordinary customs duties that may qualify for drawback from antidumping deposits and final assessments that typically do not.

Frequently Asked Questions

Does the 1.89% Rate Apply to All Turkish Large Diameter Welded Pipe?

No. The 1.89% rate applies to the reviewed HDM entities and Cimtas. Other previously reviewed or investigated companies generally retain their latest company-specific rates. The 1.57% all-others rate remains applicable when neither the exporter nor the producer has a controlling company-specific rate.

Which Date Controls the New Cash Deposit Requirement?

The relevant date is generally the date merchandise is entered, or withdrawn from warehouse, for consumption. Covered entries on or after September 25, 2026, are subject to the updated deposit instructions. Order, invoice, export, and arrival dates do not independently determine the applicable deposit rate.

Are Cash Deposits the Final Antidumping Duties Owed?

Not necessarily. Cash deposits are provisional security collected at entry. Final liability is determined through assessment and liquidation, typically after an administrative review. The assessed amount can be higher or lower than the original deposit, creating additional duty exposure or a potential refund.

What Happens When the Exporter Is Not Reviewed but the Producer Is?

If the exporter lacks an applicable company-specific rate but the producer has one, the producer’s rate generally controls. Accurate manufacturer identification is therefore required before entry filing. When neither party has an applicable rate, the all-others rate typically applies.

Can Antidumping Duties Be Recovered Through Drawback?

Generally, no. Antidumping cash deposits and assessed antidumping duties are typically excluded from drawback. Importers should not include these amounts in projected drawback recoveries without a transaction-specific legal and compliance review.
