Silicon Metal from Angola and Laos Now Taxed Heavily
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!

U.S. Antidumping Orders Issued
On April 16, 2026, the U.S. issued antidumping duty orders on silicon metal from Angola and Laos. Commerce will direct Customs and Border Protection to suspend liquidation and to assess antidumping duties equal to the amount by which normal value exceeds export price on subject entries.
Required Cash Deposit Rates
Effective on the publication of the ITC's final determination (April 16, 2026), CBP will require cash deposits at the estimated weighted-average dumping margins: 68.45 percent for silicon metal from Angola and 94.44 percent for silicon metal from Laos. These deposits are required at the same time importers normally deposit estimated customs duties.
Semiconductor-Grade Silicon Excluded
Silicon metal that is semiconductor grade (contains at least 99.99 percent silicon by weight and classifiable under HTSUS 2804.61.0000) is excluded from these antidumping orders. Imports of semiconductor-grade silicon are therefore not subject to these AD orders.
No CVD Offset for Laos Rates
Commerce did not offset the Laos antidumping cash deposit rates by any countervailable export subsidies because the final countervailing duty determination for Laos was based on adverse facts available. Therefore, the Laos cash deposit rate remains 94.44 percent.
Which Entry Dates Are Covered
Antidumping duties will be assessed on unliquidated entries of silicon metal from Angola and Laos entered or withdrawn for consumption on or after September 30, 2025. However, entries made on or after January 28, 2026 were liquidated without regard to antidumping duties because provisional measures expired; suspension of liquidation and cash deposit collection resume on April 16, 2026.
