Do you expect the cost of your household electronics to rise in the coming months?
In September 2026, U.S. import prices for arsenic metal rose to $1,000 per metric ton on a CFR Houston basis. This price escalation reflects tightening upstream supplies from China and logistics disruptions in the Strait of Hormuz.
Why it matters
The price surge stems from high demand across semiconductor, AI data center, and defense electronics sectors. Fabricators are accelerating procurement to secure materials ahead of scheduled device production runs.
Arsenic metal prices reached $1,000 per metric ton on a cost-and-freight (CFR) Houston basis in September 2026. The increase is driven by constrained supply chains and intensified procurement activity for semiconductor manufacturing.
The players
5N Plus
A specialty chemicals and materials company that focuses on semiconductor-grade materials and received a defense award for domestic gallium arsenide production.
The details
Arsenic metal serves as a precursor for gallium arsenide, a compound semiconductor material used in high-frequency and optoelectronic devices. Supply constraints are compounded by disruptions in the Strait of Hormuz and China's dominance as the primary global supplier. Fabricators are currently front-loading inventory for Q4 2026 device runs to mitigate future uncertainty.
Timeline
September 2026: U.S. arsenic metal import prices increased to $1,000 per metric ton.
Q4 2026: Semiconductor fabricators increased procurement for upcoming device runs.
Year-end 2026: Seasonal inventory management is expected to soften demand.
The Tech Race
The spike in arsenic prices underscores the supply chain volatility currently complicating U.S. efforts to establish domestic gallium arsenide component production. This race for material security is critical for maintaining independence in the semiconductor and defense electronics sectors.
Manufacturers of semiconductor and defense hardware may face higher bill-of-materials costs as spot prices for essential precursors rise. Procurement teams expect seasonal demand to temper following the year-end inventory cycle.
The takeaway
The upward price trajectory in arsenic metal signals intensifying competition for raw materials used in AI and defense electronics. Stakeholders should monitor seasonal inventory reports at year-end 2026 for signs of cooling market pressure.
