What changed

The U.S. International Trade Commission (USITC) has issued a final determination that imports of silicon metal from Angola and Laos are causing material injury to the U.S. industry. This affirmative finding, based on the Department of Commerce's determinations of less than fair value sales and subsidies, will lead to the issuance of antidumping duty orders on imports from Angola and Laos, and a countervailing duty order on imports from Laos. The investigation into imports from Thailand was terminated as the subsidized imports were found to be negligible.

This determination means that U.S. importers and domestic manufacturers of silicon metal will face new trade remedy duties on products originating from Angola and Laos. Companies involved in the import or domestic production of silicon metal should review the specific duty rates to be issued by the Department of Commerce and adjust their pricing and supply chain strategies accordingly. The USITC's public report is expected by April 29, 2026.

What to do next

The U.S. International Trade Commission (Commission or USITC) today determined that a U.S. industry is materially injured or threatened with material injury by reason of imports of silicon metal from Angola and Laos that the U.S. Department of Commerce (Commerce) has determined are sold in the United States at less than fair value by Angola and Laos and subsidized by the government of Laos.

The Commission further found that the imports of these products from Thailand that Commerce has determined are subsidized are negligible and voted to terminate the countervailing duty investigation concerning Thailand.

Chair Amy A. Karpel and Commissioners David S. Johanson and Jason E. Kearns voted in the affirmative for Angola and Laos. They made a finding of negligibility with respect to the countervailing duty investigation involving Thailand.

As a result of the Commission’s affirmative determinations, Commerce will issue antidumping duty orders on imports of this product from Angola and Laos and a countervailing duty order on imports of this product from Laos. As a result of the finding of negligibility, the countervailing duty investigation regarding imports from Thailand will be terminated.

The Commission’s public report on Silicon Metal from Angola, Laos, and Thailand (Inv. Nos. 701-TA-761, 701-TA-763, 731-TA-1743 and 731-TA-1745 (Final), USITC Publication 5720 , April 2026) will contain the views of the Commission and information developed during the investigations.
