1. Report Industry Investment Rating No relevant content provided. 2. Core Views - The supply - demand pattern of caustic soda has limited changes and will maintain a narrow - range oscillation in the short term. It is in a downward oscillation phase, and the later price center is expected to decline. The current and expected supply - demand patterns are significantly different. The upstream has reported production this year, and the demand shows weakness. As winter approaches, the active de - stocking pressure of upstream enterprises may impact the spot market. Attention can be paid to the rebound of the futures market [2][4]. - It is recommended that production enterprises use options for inventory management, trade enterprises consider building inventory and use options for procurement and inventory management, and terminal customers use options for procurement and inventory management according to their own situations [2]. - Key data to focus on include the commissioning of downstream alumina plants, the impact of chlorine - consuming downstream on the comprehensive profit of chlor - alkali, the maintenance information of upstream chlor - alkali enterprises, and the marginal changes in the inventory of caustic soda plants [2]. 3. Summary by Directory 3.1 Spot Price - Domestic caustic soda is divided into different specifications, mainly including 32% liquid caustic soda, 50% liquid caustic soda, and 99% flake caustic soda. The low - concentration caustic soda market price in the region weakened week - on - week. In Shandong, the average market price of 32% ion - exchange membrane liquid caustic soda decreased from 807 yuan/ton (converted to 2521.875 yuan/ton of 100% caustic soda) at the beginning of the week to 801 yuan/ton (converted to 2512.5 yuan/ton of 100% caustic soda) at the end of the week. The supply in Shandong was relatively sufficient, and the demand from alumina enterprises had a certain inhibitory effect on the market [11]. 3.2 Spread 3.2.1 Model Spread - The spreads between 50% caustic soda and 32% caustic soda in Shandong, Jiangsu, Zhejiang, and Shaanxi, as well as the spreads between 99% flake caustic soda and 32% caustic soda in Shandong, Inner Mongolia, and Shaanxi, showed different trends over time [29]. 3.2.2 Regional Spread - The regional spreads of 32% caustic soda, 50% caustic soda, and 99% flake caustic soda in different regions such as Shandong, Jiangsu, Zhejiang, and Shaanxi also had different performance trends [29][33]. 3.3 Supply - China's caustic soda production capacity is mainly concentrated in North China, Northwest China, and East China, accounting for 80% of the total national production capacity. This week, the domestic caustic soda output is expected to be 877,810 tons, a week - on - week increase of 367 tons, and the weekly operating rate of liquid caustic soda enterprises is 88.74%, a week - on - week increase of 0.40%. The maintenance arrangements in the chlor - alkali market this week are less, and the supply has increased [40]. 3.3.1 Load and Output - The weekly operating rates and outputs of liquid caustic soda and flake caustic soda showed different trends over time [41][45]. 3.3.2 Maintenance Situation - Many chlor - alkali enterprises have experienced long - term shutdowns, maintenance, and restarts. This week, the expected impact on the output of 100% caustic soda is 19,420 tons. Some enterprises also have future maintenance plans [48]. 3.3.3 Flake Caustic Soda Plant Operating Conditions - The operating conditions of flake caustic soda plants of different manufacturers vary, including normal operation, under - capacity operation, and maintenance [52]. 3.4 Downstream Demand - Alumina: The supply decreased slightly this week. As of November 13, the built - in production capacity of alumina in China was 118 million tons, the operating production capacity was 95.9 million tons, and the operating rate was 83.54% [55]. - Viscose staple fiber: The capacity utilization rate of the viscose staple fiber industry from November 7 - 13, 2025 was 89.50%, a week - on - week decrease of 0.1% [55]. - Printing and dyeing industry: As of November 13, the comprehensive operating rate in the Jiangsu and Zhejiang regions was 66.55%, a week - on - week decrease of 1.52%. The overall operating rate of dyeing factories showed differentiation, and the order situation was not good [55]. 3.5 Inventory - As of November 14, 2025, the inventory of liquid caustic soda plants in China was 254,100 tons, a week - on - week increase of 2.04%, and the inventory of flake caustic soda plants was 37,300 tons, a week - on - week increase of 0.81%. The market demand did not improve significantly, and the inventory showed an increasing trend [74]. 3.6 Valuation - Cost side: The price of industrial salt in China remained stable this week, and the price of thermal coal increased slightly. The production cost of caustic soda mainly comes from raw salt and electricity, with electricity accounting for about 60% of the total cost [78]. - Profit: The comprehensive profit of chlor - alkali on the spot side weakened week - on - week [79]. 3.7 Chlorine - Consuming Downstream - The report also provided price, operating rate, and profit data of PVC, epoxy propane, and epichlorohydrin, which are chlorine - consuming downstream products [87][96].
