U.S. continues antidumping and CVD orders on silicon metal
On September 15, 2026, the US Department of Commerce confirmed continuation of antidumping duty orders on silicon metal imports from Bosnia and Herzegovina, Iceland, Malaysia, and a countervailing duty order on Kazakhstan. The orders remain due to likely dumping, subsidies, and injury to US industry.
What changed
The US Department of Commerce and International Trade Commission decided not to revoke antidumping duty (AD) and countervailing duty (CVD) orders on silicon metal from Bosnia and Herzegovina, Iceland, Malaysia, and Kazakhstan following sunset reviews initiated in March 2026.
The orders, originally published between April and August 2021, cover silicon metal containing 85% to under 99.99% silicon, excluding semiconductor grade. Effective September 3, 2026, US Customs will maintain existing AD and CVD cash deposits at current rates.
The decision followed findings that revoking duties would likely cause continuation or recurrence of dumping, subsidization, and material injury to US industry. Next five-year reviews are expected by 2031.
Action Steps for Importers of Silicon Metal
- Verify continued antidumping and countervailing duty cash deposit requirements for shipments from Bosnia and Herzegovina, Iceland, Malaysia, and Kazakhstan.
- Exclude semiconductor grade silicon (≥99.99% purity) from AD/CVD scope in compliance filings.
- Monitor potential initiation of next five-year (sunset) review by mid-2031 to prepare for possible changes.
