The United States International Trade Commission (Commission or USITC) today determined that a U.S. industry is materially injured by reason of imports of multifunctional acrylate and methacrylate monomers and oligomers (MAMMOs) from Taiwan that the U.S. Department of Commerce (Commerce) has determined are sold at less than fair value and subsidized by the government of Taiwan.
Chair Amy A. Karpel and Commissioners David S. Johanson and Jason E. Kearns voted in the affirmative.

USITC Makes Determinations in Five-Year (Sunset) Reviews Concerning Carbon and Certain Alloy Steel Wire Rod from Brazil, Indonesia, Mexico, Moldova, and Trinidad and Tobago
The U.S. International Trade Commission (Commission or USITC) today determined that revoking the existing countervailing duty order on carbon and certain alloy steel wire rod from Brazil and the antidumping duty orders on carbon and certain alloy steel wire rod from Brazil, Indonesia, Mexico, Moldova, and Trinidad and Tobago would likely lead to continuation or recurrence of material injury within a reasonably foreseeable time.
As a result of the Commission’s affirmative determinations, the existing orders on imports of this product from Brazil, Indonesia, Mexico, Moldova, and Trinidad and Tobago will remain in place.
Chair Amy A. Karpel and Commissioners David S. Johanson and Jason E. Kearns voted in the affirmative.

BACKGROUND
The Uruguay Round Agreements Act requires the Department of Commerce to revoke an antidumping or countervailing duty order, or terminate a suspension agreement, after five years unless the Department of Commerce and the USITC determine that revoking the order or terminating the suspension agreement would be likely to lead to continuation or recurrence of dumping or subsidies (Commerce) and of material injury (USITC) within a reasonably foreseeable time.
The Commission’s institution notice in five-year reviews requests that interested parties file responses with the Commission concerning the likely effects of revoking the order under review as well as other information. Generally, within 95 days from institution, the Commission will determine whether the responses it has received reflect an adequate or inadequate level of interest in a full review. If responses to the USITC’s notice of institution are adequate, or if other circumstances warrant a full review, the Commission conducts a full review, which includes a public hearing and issuance of questionnaires.
The Commission generally does not hold a hearing or conduct further investigative activities in expedited reviews. Commissioners base their injury determination in expedited reviews on the facts available, including the Commission’s prior injury and review determinations, responses received to its notice of institution, data collected by staff in connection with the reviews, and information provided by the Department of Commerce.
The five-year (sunset) reviews concerning Carbon and Certain Alloy Steel Wire Rod from Brazil, Indonesia, Mexico, Moldova, and Trinidad and Tobago were instituted on July 1, 2025.
On November 24, 2025, the Commission determined to conduct expedited five-year reviews. Chair Amy A. Karpel and Commissioners David S. Johanson and Jason E. Kearns concluded that the domestic interested party group responses were adequate, and the respondent interested party group responses were inadequate, and voted for expedited reviews.
