Mexico Rebar Antidumping Review: 11.38% Final Rate

The Mexico rebar antidumping duty landscape has changed for importers sourcing from Deacero Group. A final 11.38 percent dumping margin affects new cash deposits, while entries from the 2023-2024 review period remain subject to separate liquidation calculations that may create additional liability or refunds.

What the 11.38 Percent Final Margin Means

The final administrative review covers subject steel concrete reinforcing bar from Mexico entered during the period from November 1, 2023, through October 31, 2024. Commerce determined that Deacero Group sold subject merchandise in the United States at less than normal value and assigned the company a final weighted-average dumping margin of 11.38 percent.

Deacero Group is treated as a single collapsed entity consisting of Deacero S.A.P.I. de C.V., I.N.G.E.T.E.K.N.O.S. Estructurales, S.A. de C.V., and Aceros Turia S.A. de C.V. Importers and brokers should therefore evaluate whether commercial invoices, manufacturer identifications, supplier records, and entry documentation reference any of these entities.

The Final Rate Replaces the Preliminary Result

The final 11.38 percent margin is higher than the preliminary margin of 8.45 percent. The change followed verification and Commerce's use of partial adverse facts available. Issues evaluated in reaching the final result included insurance revenue and gross unit price, cost of production, scrap and waste, and a constructed export price offset.

For subject entries made on or after November 16, 2026, the cash deposit rate for Deacero Group generally becomes 11.38 percent. This deposit is security against future antidumping liability. It is not necessarily the final amount that will be owed when the entry liquidates.

Companies without their own company-specific rate generally remain subject to the applicable 20.58 percent all-others rate from the original investigation. The correct rate depends on the producer, exporter, transaction structure, and scope status of the merchandise. Using a supplier's name alone, without confirming the producer and exporter combination, can result in an incorrect deposit.

Cash Deposits and Final Assessments Are Different

Antidumping administration separates prospective cash deposits from retrospective duty assessment. The 11.38 percent rate determines the deposit generally required for new Deacero Group entries beginning on the effective date. Entries made during the review period, however, are expected to liquidate using importer-specific assessment rates calculated from the reviewed sales data.

That distinction matters for forecasting. An importer may have deposited duties at the rate in effect when merchandise entered, but the final assessment associated with those entries may be higher or lower. The difference can produce an additional bill or a refund, typically with applicable interest.

Review Period Entries Require Separate Monitoring

Commerce intends to provide assessment instructions to U.S. Customs and Border Protection no earlier than 41 days after publication of the final results. Importers should not assume that liquidation will occur immediately after those instructions are issued. CBP processing, suspension status, litigation, protests, and other case-specific circumstances can affect timing.

The all-others rate of 20.58 percent also remains important for certain non-reviewed companies that do not have an individual rate. In addition, automatic assessment at the all-others rate may apply to certain intermediary transactions when Deacero Group did not know that the merchandise was destined for the United States.

Customs brokers should maintain distinct controls for the entry-date deposit rate and the eventual assessment rate. Entry audit files should identify the manufacturer, exporter, importer of record, case number, applicable deposit rate, entered value, and review period. Importers should also preserve purchase orders, mill certificates, invoices, payment records, and supply-chain communications needed to explain the transaction structure.

Compliance Steps for Rebar Importers and Brokers

The immediate operational task is to update antidumping duty controls for entries on or after November 16, 2026. Broker instructions, product databases, supplier profiles, and landed-cost models should reflect the 11.38 percent Deacero Group cash deposit rate where the merchandise is within scope and the producer-exporter combination qualifies for that rate.

Importers should also identify all unliquidated entries of Mexican rebar from the November 1, 2023, through October 31, 2024 review period. Deposit amounts should be reconciled against potential importer-specific assessment exposure. Finance teams may need to adjust accruals if existing estimates rely on the preliminary 8.45 percent margin or another outdated rate.

Scope and Supply-Chain Data Remain Critical

The commercial description of a product does not determine antidumping coverage by itself. The written scope generally controls, while tariff classifications serve as administrative references. Rebar specifications, dimensions, chemistry, processing, country of origin, and producer identity should be reviewed before applying or excluding an antidumping case.

Businesses purchasing through distributors or trading companies face additional risk because the exporter shown on the entry may differ from the producing mill. The transaction chain should be documented before entry so the broker can apply the appropriate case number and rate. Where information is incomplete, the importer should resolve the discrepancy rather than rely on a product description such as “Mexican rebar.”

Landed-cost forecasts should separately account for the regular customs duty, antidumping cash deposit, merchandise processing fee, freight, and any other applicable trade measures. Antidumping and countervailing duties generally cannot be recovered through duty drawback. Importers should therefore avoid treating the 11.38 percent deposit as drawback-eligible when estimating recovery opportunities. Other eligible customs duties may still support drawback claims if the statutory and documentary requirements are satisfied.

Frequently Asked Questions

What is the final antidumping rate for Deacero Group rebar?

The final weighted-average dumping margin is 11.38 percent. This rate generally becomes the cash deposit rate for subject Deacero Group merchandise entered, or withdrawn from warehouse for consumption, on or after November 16, 2026. The applicable rate still depends on the producer, exporter, scope status, and entry facts.

Does the 11.38 percent rate determine liquidation for all reviewed entries?

Not necessarily. The 11.38 percent margin is the company-level result and prospective cash deposit rate. Entries from November 1, 2023, through October 31, 2024 are generally assessed using importer-specific rates calculated for the administrative review. Final liquidation liability may therefore differ from the amount originally deposited.

What rate applies to Mexican rebar companies that were not reviewed?

A company without its own rate will generally remain subject to the 20.58 percent all-others rate established in the original investigation. However, rate selection can depend on the producer-exporter combination and transaction chain. Brokers should verify the actual manufacturer and exporter rather than applying a rate based only on the seller's invoice.

When will CBP receive assessment instructions?

Assessment instructions are expected no earlier than 41 days after publication of the final results. The issuance of instructions does not guarantee immediate liquidation. Importers should continue monitoring suspended entries and should retain review-period records until liquidation status and any resulting bills or refunds are confirmed.

Can antidumping duties on Mexican rebar be recovered through duty drawback?

Antidumping and countervailing duties generally are not refundable through duty drawback. Importers may still be able to recover eligible regular customs duties, taxes, or fees associated with qualifying imported and exported merchandise. Drawback calculations should separate eligible amounts from AD and CVD deposits to prevent unsupported claims.

What should an importer do if a trader purchased the rebar from Deacero?

The importer should document the full transaction chain, including the producing mill, exporter, intermediary, country of origin, and U.S. destination knowledge. Intermediary transactions can affect assessment treatment, particularly where the producer did not know the goods were destined for the United States. The broker should receive verified party data before filing the entry.

How Stable Software Can Help

Separate Eligible Drawback From Nonrecoverable AD Duties

The final Deacero Group rate reinforces the importance of distinguishing antidumping deposits from customs duties that may qualify for drawback. Stable Software's DrawbackAI gives U.S. customs brokers a duty drawback software option they can white-label for importer clients and use to file under their own filer code.

Stable Software charges a flat software license and never takes a percentage of the importer's refund. Customs brokers evaluating drawback programs can use this model to retain control of client relationships while keeping recovery economics transparent. Although antidumping and countervailing duties generally cannot be recovered through drawback, qualifying regular duties may still represent a meaningful opportunity for importers with eligible exports or destroyed merchandise.
