Tongwei joined a CNY 43,000 per tonne cost floor for polysilicon at a closed-door industry meeting held on October 11, 2026. As Futu reported on October 13, the meeting linked pricing to a CNY 43,000 per tonne cost baseline and discussed production controls.

What the floor means for margins

The proposal matters because Tongwei combines polysilicon production with solar cells, modules and photovoltaic projects. The company listed annual polysilicon capacity above 840,000 tonnes as of April 2026 on its investor-relations page, giving the pricing discussion direct relevance to a large operating base.

The same report said leading producers would coordinate output with demand rather than impose an artificial market price. That distinction leaves execution as the key variable: a cost floor can support realized prices, but it does not by itself guarantee shipments or profit.

Scale meets a weak earnings backdrop

Tongwei's corporate profile also shows the scale behind the debate. Tongwei said on September 23, 2026, that its brand value reached CNY 275.639 billion and that cumulative solar-cell shipments exceeded 400 GW. Those figures contrast with the industry's current need to reduce supply and protect pricing.

The Shanghai Stock Exchange listing, ticker 600438 and ISIN CNE000001GS3 are identified by Finanz und Wirtschaft. Tongwei stock was last at CNY 11.51 on the Shanghai Stock Exchange on October 14, 2026 at 11:30 a.m. CST. Its market capitalization was CNY 50.6 billion, while the 52-week range stood at CNY 10.32 to CNY 27.75, placing the latest quote CNY 1.19 above the yearly low.

Supply control is the next test

The investment case now turns on whether production discipline reaches actual output and pricing. Tongwei's stated scale creates operating leverage in either direction: a CNY 43,000 floor could improve economics if demand absorbs supply, while weak downstream orders could limit the benefit.
