Angola and Laos Silicon Hit with U.S. Import Taxes
Published Date: 4/16/2026
Notice
Summary
Starting April 16, 2026, the U.S. is putting special taxes on silicon metal imported from Angola and Laos because these imports were sold at unfairly low prices and hurt American businesses. This means companies bringing in silicon metal from these countries will have to pay extra fees, helping U.S. producers compete fairly. If you’re in the silicon metal business, watch out for these new costs and rules!
Analyzed Economic Effects
3 provisions identified: 1 benefits, 2 costs, 0 mixed.
Large Tariffs Imposed on Silicon Metal
If you import silicon metal from Angola or Laos, U.S. Customs will require cash deposits and may assess antidumping duties starting with the notice published April 16, 2026. Commerce set estimated weighted-average dumping margins of 68.45 percent for Angola (including PC Silicon Co. Limited and Wanhongda International Limited) and 94.44 percent for Laos (including Lao Silicon Co., Ltd). These rates apply to producers/exporters listed and to "All Others."
Which Past Shipments Face Duty Assessments
Antidumping duties will be assessed on unliquidated entries of silicon metal that were entered or withdrawn for consumption on or after September 30, 2025 (the date of the preliminary LTFV determinations) but will not include entries that occurred after the provisional measures expired on January 28, 2026 and before the ITC final injury determination. The effective assessment window is therefore entries from September 30, 2025 through January 27, 2026.
No Duties on Entries After Jan 27, 2026
Entries of silicon metal from Angola and Laos that were entered or withdrawn from warehouse for consumption on or after January 28, 2026 were liquidated without regard to antidumping duties. If you imported subject merchandise on or after January 28, 2026, those entries were not assessed antidumping duties as a result of the provisional measures expiring.
