Summary: On April 20, 2026, industrial silicon spot prices remain stable while futures edge up slightly, supported by strong cost factors and stable rigid demand from downstream silicone monomer factories.
BEIJING, April 20, 2026 — As the core upstream raw material of the silicone industry, industrial silicon prices maintained a steady trend on April 20, with futures prices moving up moderately driven by cost support. The spot price of 553# industrial silicon (oxygen-free) in East China was quoted at 9,000 yuan/ton, and 421# at 9,300 yuan/ton, both unchanged from the previous day.
On the Zhengzhou Commodity Exchange, the main industrial silicon futures contract SI2605 closed at 8,580 yuan/ton, an increase of 30 yuan/ton (+0.35%) from the previous trading day, with active trading volume, reflecting strong market sentiment. The stable operation of industrial silicon prices is mainly supported by three factors: high power and silicon coal costs, environmental protection production restrictions in major producing areas, and stable operating rates of downstream silicone monomer factories (around 65%), which maintain rigid procurement demand.
Industry insiders predict that industrial silicon prices will fluctuate slightly strongly in the short term, with key attention paid to hydropower season electricity prices and equipment maintenance progress of major enterprises.
