[A number of silicon material companies jointly held a closed-door meeting and agreed that the average cost including tax price should not be less than 43,000 yuan per ton] On October 13, the reporter learned from participating companies that on October 11, a number of silicon material leading companies held a closed-door meeting in Hangzhou and agreed that the average cost price including tax of silicon materials (including Siemens process and granular silicon) and the corresponding sales price should not be less than 43,000 yuan per ton. Some business people told reporters that the price is the true cost line after taking into account industrial silicon, electricity charges, depreciation, and labor. Xiaocai's note: In August this year, eight domestic polysilicon companies jointly signed an anti-involution "Proposal" in Shanghai, promising that the sales price of all photovoltaic products (including bidding quotations) shall not be lower than the corresponding cost calculated in accordance with the group standard "General Principles of the Photovoltaic Industry Cost Accounting Model".
