Report Industry Investment Rating - Unilateral: Neutral for polysilicon; short - term range operation for polysilicon [5][7] - Inter - period: None for both industrial silicon and polysilicon [2][5][7] - Inter - commodity: None for both industrial silicon and polysilicon [2][5][7] - Spot - futures: None for both industrial silicon and polysilicon [2][5][7] - Options: None for both industrial silicon and polysilicon [2][5][7] Core View - Industrial silicon's short - term supply - demand fundamentals are average. The intraday sharp rise and then fall of the industrial silicon futures are mainly affected by the rise of coking coal. The short - term industrial silicon futures are affected by the overall commodity sentiment and policy - related news. If there are policies to promote, the futures may have room to rise as the current valuation is low [2] - The supply - demand fundamentals of polysilicon are average. The current futures are affected by the anti - involution policy and weak reality. The policy is still in progress, and the futures fluctuate greatly. In the medium - to - long - term, it is suitable to go long on polysilicon at low prices [7] Market Analysis Industrial Silicon - On September 15, 2025, the industrial silicon futures price was strong. The main contract 2511 opened at 8,725 yuan/ton and closed at 8,800 yuan/ton, up 0.86% from the previous settlement. The position of the main contract 2511 was 290,948 lots, and the number of warehouse receipts was 49,905 lots, down 93 lots from the previous day [1] - The spot price of industrial silicon rose slightly. The price of East China oxygen - passing 553 silicon was 9,100 - 9,300 yuan/ton, and 421 silicon was 9,400 - 9,600 yuan/ton. The price of Xinjiang oxygen - passing 553 silicon was 8,600 - 8,700 yuan/ton, up 50 yuan/ton, and 99 silicon was also 8,600 - 8,700 yuan/ton, up 50 yuan/ton. The silicon prices in Kunming, Huangpu Port, Northwest, Tianjin, Xinjiang, Sichuan, and Shanghai regions rose slightly, and the price of 97 silicon was slightly adjusted up [1] - The quotation of silicone DMC was 10,700 - 10,900 yuan/ton, up 100 yuan/ton. The monomer factory's pre - sales orders were sufficient, and the inventory pressure was not large. Downstream enterprises' procurement rhythm remained unchanged, mainly replenishing stocks at low prices, with limited support for the market. Silicone is expected to stabilize in the short term [1] Polysilicon - On September 15, 2025, the main contract 2511 of polysilicon futures fluctuated. It opened at 53,630 yuan/ton and closed at 53,545 yuan/ton, down 0.34% from the previous trading day. The position of the main contract was 132,212 lots (134,898 lots the previous day), and the trading volume was 237,981 lots [4] - The spot price of polysilicon remained stable. The price of N - type material was 49.10 - 54.00 yuan/kg, and n - type granular silicon was 48.00 - 49.00 yuan/kg. The inventory of polysilicon manufacturers increased, and the inventory of silicon wafers decreased. The latest polysilicon inventory was 21.90 (a month - on - month change of 3.79%), the silicon wafer inventory was 16.55GW (a month - on - month change of - 1.78%), the weekly polysilicon output was 31,200 tons (a month - on - month change of 3.31%), and the silicon wafer output was 13.88GW (a month - on - month change of 0.73%) [4] - The price of domestic N - type 18Xmm silicon wafers was 1.33 yuan/piece (up 0.05 yuan/piece), N - type 210mm was 1.68 yuan/piece (up 0.05 yuan/piece), and N - type 210R silicon wafers were 1.43 yuan/piece (up 0.05 yuan/piece) [4] - Silicon wafer enterprises may raise prices.

The price increase of 183mm is likely to be accepted by downstream, while the other two sizes need to pay attention to the transaction situation [6] - The price of high - efficiency PERC182 battery cells was 0.27 yuan/W, PERC210 battery cells were about 0.28 yuan/W, TopconM10 battery cells were about 0.32 yuan/W (up 0.01 yuan/W), Topcon G12 battery cells were 0.31 yuan/W (up 0.01 yuan/W), Topcon210RN battery cells were 0.29 yuan/W, and HJT210 half - cell battery was 0.37 yuan/W [6] - The mainstream transaction price of PERC182mm components was 0.67 - 0.74 yuan/W, PERC210mm was 0.69 - 0.73 yuan/W, N - type 182mm was 0.67 - 0.69 yuan/W, and N - type 210mm was 0.67 - 0.69 yuan/W [6] Strategy Industrial Silicon - The spot price rose slightly following the futures. The short - term supply - demand fundamentals are average. The short - term industrial silicon futures are affected by the overall commodity sentiment and policy - related news. Attention should be paid to whether there are policies for capacity withdrawal. If there are policies to promote, the futures may have room to rise [2] Polysilicon - The supply - demand fundamentals are average. The current futures are affected by the anti - involution policy and weak reality. Participants should pay attention to risk management. They need to continuously follow up on the implementation of policies and the downward transmission of spot prices. In the medium - to - long - term, it is suitable to go long on polysilicon at low prices. Short - term range operation is recommended [7]
