How do production costs vary across Chinese polysilicon regions and what is the breakeven price?
Polysilicon cost structures are highly regional. In Xinjiang and Inner Mongolia, integrated producers with self-owned power plants enjoy electricity at 0.2-0.25 yuan/kWh, bringing cash costs to 8,000-10,000 yuan/ton for industrial silicon feedstock. Southwest producers in Yunnan/Sichuan face higher costs: 0.31-0.39 yuan/kWh during wet season and up to 0.45 yuan/kWh in dry season, plus expensive charcoal reductant imports from Myanmar at 3,500 yuan/ton delivered. This pushes their cash costs to 12,000-13,000 yuan/ton. For polysilicon itself, industry average full cost is about 45.5 yuan/kg. With N-type dense material spot prices at 31 yuan/kg as of July 2025, most producers are deeply loss-making—Tongwei alone lost 9.55 billion yuan in 2025. The cost curve is steep, meaning high-cost capacity will exit first.
