Trichlorosilane

Market Intelligence, Analysis, and Forecast for Trichlorosilane

I. Market Intelligence

Price Trends
- Recent Price Stability: From April 20 to April 23, 2026, the spot price of trichlorosilane remained stable at RMB 3,435 per ton for multiple consecutive days, with no upward or downward movement.
- Historical Price Volatility: In February 2025, the price of photovoltaic-grade trichlorosilane surged to RMB 27,000 per ton, while that of standard-grade reached RMB 22,000 per ton—a 59% increase—primarily driven by surging demand stemming from rapid expansion of polysilicon production capacity. As of April 24, 2026, the market average price for photovoltaic-grade trichlorosilane rose to RMB 3,800 per ton (tax-inclusive delivered price), and that for standard-grade increased to RMB 3,200 per ton (tax-inclusive delivered price).

Supply-Demand Dynamics
- Capacity and Operating Rate: As of April 24, 2026, the aggregate nameplate capacity across 16 surveyed enterprises stood at 862,200 tons annually, with the industry-wide average operating rate remaining stable at approximately 40%.
- Demand Structure: Photovoltaic-grade trichlorosilane accounts for the largest share of demand. In 2025, its demand volume reached 368,000 tons, representing 79.7% of total demand (462,000 tons). Although electronic-grade trichlorosilane accounted for only 6.7% of total demand, its average price was as high as RMB 89,500 per ton, with gross margins 4.2 times those of photovoltaic-grade material.

Industry Developments
- Capacity Expansion and Technological Upgrades: Xin’an Chemical completed commissioning of Phase II of its electronic-grade trichlorosilane project in Hangzhou Bay New Area in H2 2025, adding 3,000 tons/year of 6N-purity capacity; its total electronic-grade capacity now stands at 5,000 tons/year. Tangshan Sanfu initiated a technical retrofit project for hydrogen chloride (HCl) recycling, reducing HCl consumption per unit of product by 19.7%. Xinjiang Daqo invested RMB 2.86 billion in constructing a silicon-based new materials green low-carbon industrial park, including an 80,000-ton/year high-purity trichlorosilane production facility.
- Rising Market Concentration: The industry’s CR5 (combined market share of the top five enterprises) is projected to reach 57.4% in 2026, up marginally from 56.9% in 2025; CR3 (top three) rose from 36.2% to 37.1%. Leading enterprises are accelerating their capture of mid-to-high-end market share through technological barriers and vertical integration.

II. Analysis and Judgment

Reasons for Price Stability
- Supply-Demand Equilibrium: With the industry-wide average operating rate holding steady at ~40%, supply and demand remain relatively balanced, resulting in short-term price stability.
- Cost Support: Cost data from companies such as Hengguang Co., Ltd. indicate that the full production cost of photovoltaic-grade trichlorosilane ranges between RMB 11,000–12,000 per ton. Although the current market price (RMB 3,800/ton) falls significantly below this cost floor, price stability may be sustained due to factors such as enterprise inventory levels and sales strategies.

Factors Driving Price Volatility
- Downstream Demand Shifts: Demand for photovoltaic-grade trichlorosilane exhibits pronounced cyclical volatility, closely tied to polysilicon capacity deployment cycles. In contrast, demand for electronic-grade material is underpinned by ongoing wafer fab expansions (e.g., SMIC, Yangtze Memory Technologies) and national initiatives to achieve self-reliance in critical semiconductor supply chains—including photoresists and silicon wafers—supporting sustained growth.
- Raw Material Costs: Fluctuations in prices of key raw materials—such as metallurgical-grade silicon and chlorine gas—directly impact trichlorosilane production costs and thereby influence market pricing.

Industry Trends
- Technological Advancement and Innovation: Enterprises are enhancing competitiveness by developing new technologies and processes to improve product quality and reduce costs. Examples include Xin’an Chemical’s high-purity electronic-grade purification technology and Tangshan Sanfu’s HCl recycling process.
- Green and Low-Carbon Development: Stricter environmental regulations are prompting firms to adopt advanced environmental protection technologies—e.g., tail-gas recovery and by-product recycling—to comprehensively upgrade both production processes and emission control systems. Concurrently, coupling with green electricity has emerged as a new competitive dimension: leading players are investing in green power generation capacity to reduce the carbon footprint of their products.

III. Forecast

Price Trend Forecast
- Short-Term Stability: Under conditions of relative supply-demand balance and stable raw material costs, trichlorosilane prices are likely to remain stable in the near term.
- Medium- to Long-Term Volatility: As polysilicon capacity gradually comes online and electronic-grade demand continues to grow robustly, photovoltaic-grade trichlorosilane prices may experience fluctuations driven by shifting supply-demand dynamics. Electronic-grade trichlorosilane prices, however, are expected to remain elevated over the medium term due to high technical barriers and lengthy customer qualification cycles.

Industry Development Trend Forecast
- Further Consolidation of Market Concentration: Leading enterprises will continue expanding their mid-to-high-end market share via technological differentiation and deeper vertical integration. Meanwhile, smaller manufacturers may face consolidation or exit amid intensifying environmental compliance scrutiny and dual-control policies on energy consumption and intensity.
- Green and Low-Carbon Technology as a Core Competitive Edge: With global carbon neutrality goals advancing, green and low-carbon technologies will become pivotal to cost reduction and competitive advantage. Enterprises will ramp up investment in environmental infrastructure and green power capacity, steering the industry toward low-energy, low-emission, sustainable production models.

Demand Forecast
- Continued Growth in Photovoltaic-Grade Demand: Driven by sustained global PV installation momentum and progressive polysilicon capacity ramp-up, demand for photovoltaic-grade trichlorosilane will continue growing.
- Rapid Growth in Electronic-Grade Demand: Against the backdrop of wafer fab expansions by SMIC, Yangtze Memory Technologies, and broader efforts to secure domestic supply chains for photoresists and silicon wafers, demand for electronic-grade trichlorosilane is projected to grow rapidly—outpacing overall industry growth significantly.
