Methionine Antidumping Duties Enter Full ITC Review

U.S. importers cannot treat the methionine antidumping duties on products from France, Japan, and Spain as winding down. Commerce has found that dumping would likely continue or recur if the orders were revoked, while full ITC reviews will determine whether the domestic industry remains vulnerable to material injury.

What Commerce Determined in the Sunset Reviews

Likely Dumping Margins by Country

Commerce completed expedited first sunset reviews covering methionine from France, Japan, and Spain on October 5, 2026. It determined that revocation of the antidumping duty orders would likely lead to continued or recurring dumping at weighted-average margins of up to 43.82% for France, 76.50% for Japan, and 37.53% for Spain.

These percentages represent the dumping margins Commerce identified for purposes of its sunset analysis. They are not new cash deposit rates. Importers should continue applying the cash deposit rates currently associated with the applicable exporter, producer, or case instructions unless Customs and Border Protection receives new liquidation or deposit instructions from Commerce.

Why the Reviews Were Expedited

Commerce initiated the five-year reviews on June 1, 2026. Novus International participated as the domestic interested party, but no foreign respondent submitted a substantive response. Commerce therefore conducted expedited 120-day reviews rather than full reviews on the dumping question.

An expedited sunset review does not mean the underlying antidumping duty order has received a temporary extension or that deposits have been recalculated. It means Commerce made its likelihood determination on an accelerated record because respondent participation was insufficient. The agency concluded that dumping would likely continue or recur if the orders disappeared.

Importers should distinguish this country-level sunset determination from company-specific administrative review results. Administrative reviews may establish different assessment and cash deposit rates for particular producers or exporters. The sunset margins do not override those rates. Entry teams should continue validating the correct case number, producer, exporter, country of origin, and deposit rate for every covered entry.

Why the ITC Is Conducting Full Five-Year Reviews

Commerce and the ITC Answer Different Questions

Sunset proceedings divide responsibility between two agencies. Commerce evaluates whether dumping would likely continue or recur if an order were revoked. The U.S. International Trade Commission evaluates whether revocation would likely lead to continued or recurring material injury to the U.S. industry within a reasonably foreseeable period.

Both findings are generally necessary for an antidumping duty order to remain in place. Commerce has completed its part of the first sunset review for these methionine orders. The ITC must now complete the injury analysis before the government determines whether each order should continue or be revoked.

Full Reviews Will Cover All Three Countries

The ITC decided on September 4, 2026, to conduct full five-year reviews of the orders covering France, Japan, and Spain. Domestic industry responses and the response from Japanese interested parties were considered adequate. Responses from French and Spanish parties were considered inadequate, but the ITC chose to conduct full reviews for all three countries for administrative efficiency.

A full review generally provides a more developed process than an expedited review. It may involve questionnaires, written submissions, staff analysis, a hearing, and opportunities for interested parties to address market conditions, import volumes, pricing, domestic production, and likely future injury. The ITC had not announced its detailed schedule when Commerce completed its sunset determinations.

Parties considering participation should monitor the proceeding closely and evaluate whether to file an entry of appearance. Importers, foreign producers, exporters, domestic purchasers, and other interested parties may need coordinated legal, commercial, and economic input. Missed deadlines can restrict participation or reduce a party's ability to shape the record.

Compliance, Sourcing, and Drawback Implications

Continue Current Antidumping Duty Controls

The methionine antidumping duty orders remain in effect while the ITC reviews proceed. Importers should continue making cash deposits at the rates currently applicable to their entries. They should not substitute the sunset margins for established cash deposit rates or assume that a full ITC review suspends collection.

Import compliance teams should also preserve documentation supporting scope treatment, country of origin, manufacturer identity, exporter identity, entered value, and the reported antidumping duty case. Product descriptions alone may not be sufficient to establish whether merchandise is within scope. Technical specifications, chemical composition records, purchase documents, and supplier certifications may be important when classifications or product characteristics require closer analysis.

Model the Possibility of Another Five Years

If the ITC reaches affirmative injury determinations, the orders will generally continue for another five-year period, subject to administrative reviews and other proceedings. Trade directors should model this possibility in sourcing decisions, supplier negotiations, landed cost forecasts, and customer pricing. Cash deposits also create working capital demands even when final assessment rates may later differ.

Importers should avoid treating potential revocation as a baseline forecast. Until final agency action and implementing instructions establish otherwise, the prudent assumption is that the orders and associated deposit obligations remain active.

Keep Antidumping Duties Out of Drawback Calculations

Antidumping and countervailing duties are not eligible for duty drawback under 19 U.S.C. 1677h. This exclusion applies even when the imported merchandise is later exported or destroyed. Ordinary customs duties paid on the same entry may still qualify for drawback when all applicable statutory and procedural requirements are satisfied.

Drawback filers should therefore separate antidumping duty deposits and assessments from potentially recoverable ordinary duties. Entry data, accounting records, claim calculations, and broker workpapers should identify each duty type independently. Combining them can overstate potential refunds, create reconciliation problems, and expose the claimant and filer to avoidable compliance risk.

Frequently Asked Questions

Do the Sunset Margins Become New Cash Deposit Rates?

No. The margins of up to 43.82% for France, 76.50% for Japan, and 37.53% for Spain reflect Commerce's sunset analysis of likely dumping if the orders were revoked. They do not automatically replace current cash deposit rates. Importers should continue using the rates established through applicable case instructions and administrative review results.

Are the Methionine Antidumping Duty Orders Still Active?

Yes. The orders covering methionine from France, Japan, and Spain remain active during the ITC's full five-year reviews. Importers must generally continue reporting covered entries and depositing estimated antidumping duties. Revocation would require final agency determinations and subsequent implementation instructions.

When Will the ITC Complete Its Full Reviews?

A detailed schedule had not been announced when Commerce finalized its expedited sunset results. Interested parties should monitor the ITC proceeding for deadlines involving appearances, questionnaire responses, briefs, hearings, and other submissions. Internal responsibility for monitoring should be clearly assigned so that procedural deadlines are not missed.

Can Antidumping Duties on Methionine Be Recovered Through Drawback?

No. Antidumping and countervailing duties are excluded from duty drawback. However, ordinary customs duties paid on the same imported merchandise may remain eligible if the merchandise is exported or destroyed and the claim satisfies all applicable requirements. Claims should exclude AD/CVD amounts and maintain a clear audit trail showing how eligible duties were calculated.

What Should Importers Do While the Reviews Continue?

Importers should continue paying current deposits, confirm the scope and origin of imported methionine, preserve supporting records, and monitor the ITC schedule. They should also evaluate sourcing and landed cost scenarios that assume the orders continue for another five years. Companies seeking to participate in the injury reviews should promptly consult trade counsel about appearance and filing requirements.

How Stable Software Can Help

Strengthen Drawback Controls Without Including AD/CVD

Methionine entries can contain both nonrefundable antidumping duties and ordinary customs duties that may qualify for drawback after eligible exports or destruction. Customs brokers need disciplined claim calculations that keep those amounts separate and support a defensible audit trail.

DrawbackAI is flat-license duty drawback software that U.S. customs brokers can white-label for importer clients and use to file under their own filer codes. Stable Software charges a flat software license and never takes a percentage of the refund. Brokers evaluating methionine drawback opportunities can use the platform as part of a controlled process for preparing claims while excluding AD/CVD amounts from refund calculations.
