Key takeaway

What This Development Means

The United States has continued antidumping orders on silicon metal from Bosnia and Herzegovina, Iceland and Malaysia, and a countervailing duty order on Kazakhstan. The continuation is applicable from 3 September 2026 and preserves current cash-deposit requirements. The scope covers silicon metal from 85% to below 99.99% silicon, subject to specified iron content.

Which Silicon Metal Imports Remain Covered?

The orders cover silicon metal from the four named countries with at least 85.00% but less than 99.99% silicon and less than 4.00% iron by actual weight, in all forms and sizes including powder. Semiconductor-grade silicon at or above 99.99% is excluded.

Did The Continuation Notice Introduce New Duty Rates?

No. It continues the existing orders and directs Customs and Border Protection to collect cash deposits at rates in effect on the entry date. Importers must still check the applicable exporter, producer and case rate, and remember that final liability is determined at liquidation.

Silicon Metal Trade-Remedy Orders Remain In Force

United States silicon metal trade-remedy orders will continue following five-year sunset reviews by the Department of Commerce and United States International Trade Commission. Federal Register notice 2026-18790 covers antidumping orders on imports from Bosnia and Herzegovina, Iceland and Malaysia, and a countervailing duty order on imports from Kazakhstan.

The Commission determined that revoking the orders would be likely to lead to continuation or recurrence of material injury within a reasonably foreseeable time. Commerce had also found likely continuation or recurrence of dumping or countervailable subsidies.

The continuation applies from 3 September 2026, the date of the Commission's determination. The notice was published on 15 September.

Product Scope And Customs Treatment

The written scope covers all forms and sizes of silicon metal, including powder, with both of these composition limits:

  • Silicon: at least 85.00% but less than 99.99% by actual weight.
  • Iron: less than 4.00% by actual weight.

Semiconductor-grade silicon containing at least 99.99% silicon is excluded.

In-scope goods are currently entered under Harmonized Tariff Schedule of the United States subheadings 2804.69.1000 and 2804.69.5000. The excluded semiconductor-grade material is generally classified under 2804.61.0000. These codes are provided for customs convenience, while the written product description controls scope.

United States Customs and Border Protection will continue to collect cash deposits at the rates in effect at entry. The notice does not create new country rates or a new product threshold. It preserves the existing orders after the statutory reviews.

Supply-Chain Implications

Importers should validate silicon and iron content, product form, country of origin, exporter and case-specific deposit rate before entry. Certificates of analysis and supplier declarations should be linked to customs records. A change in routing or invoicing does not alter origin, and an HTSUS code alone does not determine whether merchandise is in scope.

Aluminium alloy producers, silicone and silane manufacturers, foundries and chemical formulators should model landed costs and supplier concentration. Distributors should explain that cash deposits remain provisional until liquidation and may differ from final assessed duties.

Foresight analysis. Suppliers in four countries remain subject to these trade measures. Importers sourcing from those countries must continue to account for duties in their cost comparisons. Procurement teams should weigh composition and origin evidence alongside price. An incorrect assumption that goods are excluded can create retrospective duty exposure.
