1. Report Industry Investment Rating - Not provided in the given content 2. Core Views of the Report - The industrial silicon market shows a range - bound pattern with limited upside potential. The market should focus on the upstream resumption rhythm. The 4 - 5 month period is a supply - demand destocking pattern, which supports the bottom of the market. However, the hedging pressure of Xinjiang and Southwest factories may limit the upside. The expected trading range for next week is 8300 - 8800 yuan/ton [6][7]. - The polysilicon market is weak. Attention should be paid to the impact of the concentrated cancellation at the end of May. The supply is increasing while the demand is weak. The market may continue to decline, and the expected trading range for next week is 32000 - 37000 yuan/ton [7]. 3. Summary by Relevant Catalogs 3.1 Market Data - The industrial silicon mainstream consumption reference prices in East China, Huangpu Port, Kunming, and Tianjin Port have remained relatively stable from March 10 - 27, 2026. For example, the Si5530 price in East China was 9200 yuan/ton for most days during this period [10]. 3.2 Industrial Silicon Supply Side - Smelting and Raw Material Ends - Supply: Upstream resumption is slow. The start - up rate this week is flat compared to last week. Factories in Southwest China are resuming production in small quantities, and factories in Xinjiang have no new start - up plans after resumption. The cost in the dry season in Southwest China is about 10000 yuan/ton (converted to the futures market), and about 9000 yuan/ton or more in the wet season. The current futures price does not provide a suitable hedging position for Southwest manufacturers [3]. - Inventory: The social inventory increased by 0.7 million tons, and the factory inventory decreased by 0.67 million tons, with the overall industry inventory remaining flat [3][12]. 3.3 Industrial Silicon Consumption Side - Downstream Polysilicon - Supply: The weekly production of polysilicon has increased month - on - month. There will be production capacity resumption from April to May, bringing supply increments. The current factory inventory is about 340,000 tons, and the overall industry inventory is about 500,000 tons, close to 5 months of consumption, at a relatively high level. The average full cost is about 45,000 yuan/ton, and the cash cost is about 35,000 yuan/ton [4]. - Demand: The silicon wafer production schedule has decreased week - on - week. The cancellation of export tax rebates has ended the rush - export market, and domestic demand has not improved significantly. Although European orders have increased temporarily, there is no obvious continuity. As it approaches the end of May, the concentrated cancellation of warehouse receipts will put pressure on the market [5]. 3.4 Industrial Silicon Consumption Side - Downstream Silicone - Supply: The weekly production of DMC has increased month - on - month, and most silicone factories have resumption plans. - Demand: The downstream demand is weak, and product prices have not increased. The inventory of silicone has been destocked, and the apparent demand has increased slightly month - on - month. The sustainability of demand needs attention [3]. 3.5 Industrial Silicon Consumption Side - Downstream Aluminum Alloys - The price of aluminum alloys has been continuously falling, the demand market has increased slowly, and most are in a wait - and - see state. The overseas demand has not improved, and due to stricter overseas traceability requirements, the purchase of Xinjiang silicon is restricted [3].

1. Report Industry Investment Rating - No information provided regarding the report industry investment rating 2. Core Views of the Report - Industrial silicon: The inventory increased slightly this week. The supply side is affected by electricity price changes, and there is no further increase. The demand side maintains a rigid pattern. The 3 - 4 months are in a supply - demand destocking pattern, which supports the bottom of the market. Considering the hedging pressure of upstream factories, the upside space is limited, but the downside space is supported by funds. It is recommended to buy at low levels, and the expected trading range next week is 8200 - 8800 yuan/ton [3][6][7] - Polysilicon: The market is in a weak pattern. Supply increases while demand weakens. It is in a high - inventory destocking state. The price center will decline in the early stage of destocking. The pressure of warehouse receipts near the end of May will also affect the market. The expected trading range next week is 35000 - 42000 yuan/ton [4][6][7] 3. Summary by Related Catalogs 3.1 Market Data - The report provides the reference prices of mainstream consumption areas and the transaction prices of three major ports/warehouses of industrial silicon from March 4 to March 20, 2026, including the prices of Si5530, Si4210, and Si3303 [10] 3.2 Industrial Silicon Supply Side - Smelting and Raw Material Ends - Supply: The upstream resumption of production is less than expected. The start - up rate increased slightly this week, mainly from the resumption of production in southwestern factories. Xinjiang factories have no new start - up plans for the time being. The cost in the dry season in the southwest is 10000 - 10500 yuan/ton (converted to the futures market) [3] - Inventory: This week, the social inventory increased by 0.1 million tons, the factory inventory increased by 0.07 million tons, and the overall industry inventory increased by 0.17 million tons.

The current factory inventory is about 350,000 tons, and the overall industry inventory is about 500,000 tons, close to 5 months of consumption, at a relatively high level [4] - Demand: The silicon wafer production schedule decreased week - on - week. The continuous decline in silicon wafer prices affects the psychological purchase price of silicon materials. After the end of the export rush due to the cancellation of photovoltaic tax rebates in mid - March, the domestic market has not improved significantly. Although European orders have increased this week, it is a short - term phenomenon. The overall photovoltaic demand is expected to be weak [4][5] - The report includes charts on the start - up rate, import and export volume, spot price, production volume and year - on - year change, profit calculation of the polysilicon industry, as well as the export volume of monocrystalline silicon wafers, domestic photovoltaic monthly new installed capacity, and new photovoltaic grid - connected capacity [20][21][22] 3.4 Industrial Silicon Consumption Side - Downstream Organic Silicon - The report provides charts on the average price trend, monthly start - up rate, production volume and monthly year - on - year change, factory inventory, export volume and year - on - year change, and profit calculation of domestic DMC [24][26] 3.5 Industrial Silicon Consumption Side - Downstream Aluminum Alloy - The report presents charts on the price seasonality, monthly start - up rate, average profit calculation of the recycled aluminum industry, and the seasonality of domestic automobile monthly sales [26][28]

Report Summary 1. Report Industry Investment Rating There is no information about the industry investment rating in the report. 2. Core Viewpoints - On March 17, industrial silicon fluctuated weakly. The main contract 2605 closed at 8,560 yuan/ton, with an intraday decline of 1.72%, and the open interest increased by 4,057 lots to 241,000 lots. The spot reference price of industrial silicon from Baichuan was 9,313 yuan/ton, remaining stable compared to the previous trading day. The price of the lowest deliverable product rebounded to 8,800 yuan/ton, and the spot premium expanded to 240 yuan/ton. The production resumption of industrial silicon in Xinjiang was hindered, which was structurally offset by a small amount of production resumption in the southwest. The increase in petroleum coke raw materials and the grid electricity price in Xinjiang provided cost support. Downstream demand for essential stocks was sufficient, but the willingness for incremental stocking was insufficient. The industrial silicon futures market fluctuated within a narrow range, and the spot price stabilized at the bottom [2]. - Polysilicon also fluctuated weakly. The main contract 2605 closed at 41,670 yuan/ton, with an intraday decline of 0.9%, and the open interest decreased by 549 lots to 34,098 lots. The price of N-type recycled polysilicon from Baichuan dropped to 45,500 yuan/ton, and the price of the lowest deliverable silicon material also dropped to 45,500 yuan/ton.
