1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The PVC industry in China has formed a cross - regional circulation pattern of "production in the west and consumption in the east, production in the north and consumption in the south". The industry concentration is increasing, and the scale effect and risk - resistance ability of leading enterprises are enhanced. The cost structure varies by process, and marginal devices are key to observing cost support and supply changes [4]. - The marginal devices of PVC futures are defined from multiple aspects such as policy guidance, old - age devices, production scale, and raw material procurement. Small - scale, old - age, and high - cost marginal capacities with external raw material procurement are core variables affecting short - term supply elasticity and medium - long - term cost curves [5]. 3. Summary by Relevant Catalogs PVC Industry Chain Supporting Analysis Overall Industry Situation - In 2025, the domestic PVC industry entered a period of concentrated production capacity release, with new production capacity of 2.2 million tons and an annual growth rate of 8%. The new capacity is mainly ethylene - based, increasing the proportion of ethylene - based PVC to 31% and diversifying the raw material routes. The industry has a resource - oriented layout, with the northwest and east regions having different advantages, forming a cross - regional supply - demand pattern [11]. - The industry concentration is high, and as of 2025, the top ten enterprises/groups accounted for 43% of the total production capacity, which strengthens the scale effect and market bargaining power of leading enterprises and affects market supply stability and price volatility [17]. - In terms of upstream raw materials, PVC production is mainly based on calcium carbide and liquid chlorine, and 93% of PVC production capacity is equipped with caustic soda plants, showing a high degree of integration in the chlor - alkali industry [19]. Calcium Carbide - Based PVC Supporting Analysis - In the calcium carbide - based PVC industry, enterprises with self - supplied calcium carbide account for 73% of the calcium carbide - based production capacity, mainly in the northwest and east regions, while those with externally - purchased calcium carbide account for about 27%, distributed in multiple regions, and their costs are affected by regional supply and transportation fees [20]. - The northwest region is a major surplus area of calcium carbide, while the north, central, and east regions are net purchasers. The cost of enterprises with externally - purchased calcium carbide is higher, and they are more sensitive to price fluctuations, making them key indicators for observing marginal cost changes and supply - demand adjustments [22]. - Many externally - purchased calcium carbide - based devices are in a long - term shutdown or low - load state. With the decline of chlor - alkali integration profit, some enterprises may consider reducing production [25]. - About 62% of PVC enterprises are equipped with self - supplied power plants, mainly in the northwest. In the calcium carbide - based process, enterprises with both self - supplied power plants and calcium carbide have a cost advantage, while those without either are at a disadvantage. The northwest has the lowest production cost due to coal - power integration [29]. - Most externally - purchased calcium carbide - based enterprises are operating at reduced loads, and the power spot market reform has a greater impact on them [30][32]. Ethylene - Based PVC Supporting Analysis - The raw material sources of ethylene - based PVC are diversified, including integrated ethylene, externally - purchased ethylene, and externally - purchased vinyl chloride monomer (VCM). The ethylene - based process is in line with national policies and has environmental advantages, and new PVC plants are mainly ethylene - based [33]. - Among domestic ethylene - based PVC production capacity, 31% of enterprises are self - sufficient in raw materials, while 69% rely on external procurement. Different procurement modes have different cost challenges and price sensitivities, and marginal devices are affected by external factors such as international ethylene prices and VCM import - export policies [34]. PVC Marginal Device Analysis Policy - based Identification of Marginal Capacities - Future marginal elimination capacities will mainly focus on calcium carbide - based devices with backward processes, small - scale devices, and old - age devices. Enterprises without self - supplied power plants and relying on external procurement may operate at low loads or shut down [40][41]. Capacity - Scale and Production - Time Analysis - In 2025, the PVC industry showed a significant trend of large - scale devices. Devices with a single - set capacity of more than 300,000 tons/year accounted for 60% of the total capacity, while those less than 200,000 tons/year accounted for 20%. Small - scale devices face operational pressure and a trend of being phased out [42]. - About 12% of the existing PVC production capacity was put into operation before 2005. After excluding leading enterprises' and long - term shutdown capacities, about 8% is from relatively old and small - scale devices. The impact of the "anti - involution" policy depends on subsequent implementation details [46]. Ethylene - Based Marginal Devices - Among the old - age devices, 3.6% are ethylene - based, with a relatively low risk of elimination. However, high - cost enterprises relying on external raw materials, such as Suzhou Huasu and Cangzhou Julong, are in a long - term shutdown state. Cangzhou Julong is promoting a port transformation project to reduce costs and enhance supply chain stability [50]. Calcium Carbide - Based Marginal Devices - Among the old - age devices, 8.8% are calcium carbide - based, which are more likely to be eliminated. Some "small - scale and externally - purchased calcium carbide" devices have already exited. Among the remaining 1.69 million tons of old - age calcium carbide - based PVC production capacity less than 200,000 tons, 720,000 tons are externally - purchased calcium carbide devices, which are currently operating at low loads and their operating conditions will affect industry supply elasticity and cost support [51].

Industry Investment Rating No relevant information provided. Core Views - The caustic soda industry still faces certain supply - demand pressures. Although enterprise inventories have started to decline and there is some downstream purchasing enthusiasm in some regions, inventory levels remain high. In the short term, there are no obvious positive factors, and prices are expected to be weak. The PVC market is expected to continue range - bound operation. Supply pressure remains high next week, demand is under pressure both domestically and internationally, and cost - side support is expected to weaken. Overall, the supply - demand is in an oversupply situation, and prices are not optimistic, expected to continue the weakening trend. [2][3] - Futures strategy advice: Hold short positions for caustic soda and maintain a bearish mindset for PVC; Option strategy advice: Observe for both caustic soda and PVC. [4][5] Summary by Directory Caustic Soda - **Price Trend**: The caustic soda price has experienced multiple fluctuations due to factors such as macro - environment changes, alumina demand, inventory levels, and cost changes. Currently, it is expected to be weak. [8] - **Supply Situation**: As of Thursday this week, the national weighted average operating load rate of sample enterprises was 89.84%, a 0.02 - percentage - point decrease from last week. In Shandong, the operating rate was 91.71%, an increase of 0.26%. On December 10, the inventory of 32% liquid caustic soda in expanded sample enterprises in East China decreased by 5.14% compared to December 3, and in Shandong, it decreased by 18.12%. [27] - **Device Status**: There are multiple caustic soda plants under maintenance or with planned maintenance, such as Wuhai Chemical, Zhejiang Juhua, and Ningbo Wanhua. The total maintenance loss this week is 239 tons. [28] - **Alumina Impact**: From the end of 2024 to 2025, the planned alumina production capacity to be put into operation is 12.3 million tons (including 2 million tons of replacement), with an estimated annual production capacity growth rate of around 10%. The estimated annual alumina output in 2025 is over 88 million tons, with a production growth rate of around 6%. The new alumina production capacity will increase the demand for caustic soda by around 800,000 tons per year, with a relatively concentrated demand increase of 150,000 tons from April to June. [32] - **Non - Alumina Downstream**: The textile starting rate has declined, while the viscose staple fiber starting rate has increased. [51] - **Export Situation**: In October, caustic soda exports weakened, and the estimated export profit declined. [58] Polyvinyl Chloride (PVC) - **Price Trend**: The PVC price has fluctuated due to factors such as supply - demand changes, macro - environment, and energy prices. Currently, the core contradiction is that the supply - demand has not been substantially improved, and the spot price has continued to weaken. [65][66] - **Profit Situation**: The industry profit has continued to deteriorate, including the profits of different production methods such as the calcium carbide method and the ethylene method. [71] - **Supply Situation**: This week, the domestic PVC powder industry's operating load rate decreased slightly. The overall operating load rate was 78.39%, a 0.62 - percentage - point decrease from last week. Among them, the calcium carbide - method PVC powder operating load rate decreased by 2.96 percentage points, and the ethylene - method PVC powder operating load rate increased by 4.75 percentage points. [87] - **Device Status**: There are multiple PVC plants under long - term shutdown, maintenance, or with planned maintenance, such as Taiwen Salt Chemical, Ningbo Zhenyang, and Ningbo Hanhua. [89] - **Downstream Demand**: The two major downstream industries of PVC, profiles and pipes, face pressure from both demand and industry competition. The real - estate sector still gives negative feedback on demand, and domestic demand has not improved significantly. The downstream orders are significantly lower than the average of the past five years, and both raw material and finished - product inventories are at high levels. [95] - **Real - Estate Data**: The real - estate industry is still in the bottom - building cycle, with the housing sales price index and land transaction area showing certain trends. [96] - **Inventory Situation**: The total PVC inventory is still at the highest level in recent years compared year - on - year. [103] - **External Market and Export**: Some external market prices have weakened. In October 2025, PVC exports were 312,100 tons, with an average export price of $605 per ton. Imports were 10,900 tons, with an average import price of $725 per ton. [110][121]

1. Report Industry Investment Rating - Not provided in the document 2. Core Viewpoints of the Report - Fundamental support for caustic soda is limited. As the off - season approaches, there is an expectation of further weakening in demand, and alkali plant inventories are relatively high. In terms of valuation, the liquid chlorine price is neutral. Although chlor - alkali profits have declined, production is at a high level, resulting in continuous supply pressure. In the medium to long term, the pressure of new production capacity remains, and the supply - demand pattern is weak. [1] - The high - production pattern restricts the price space of caustic soda. With insufficient fundamental support, the price is expected to maintain a weak and volatile trend. [9] 3. Summary by Relevant Catalogs 3.1 Core Contradictions and Strategy Recommendations 3.1.1 Core Contradictions - Near - term trading logic: The current supply - demand situation is weak. It is the off - season for non - aluminum demand, and speculative demand at low prices has been falling short of expectations. The overall price of alumina is under pressure, leading to a pessimistic outlook for caustic soda demand. Chlor - alkali profits are moderately low, but production is at a high level, resulting in continuous supply pressure. [8] - Long - term trading expectations: The pressure of new production capacity in the medium to long term continues, and the supply - demand pattern is weak. [3] 3.1.2 Trading - Type Strategy Recommendations - The high - production pattern restricts the price space of caustic soda. With insufficient fundamental support, the price is expected to maintain a weak and volatile trend. [9] 3.1.3 Basic Data Overview - **32% caustic soda ex - factory price (converted to futures price)**: On December 12, 2025, prices in most regions remained unchanged compared to the previous day. Only in Shaanxi, Beiyuan's price dropped by 50 yuan/ton, a decrease of 1.5%. [11] - **50% caustic soda ex - factory price (converted to futures price)**: On December 12, 2025, most prices were stable, except for Lutai, which decreased by 40 yuan/ton, a decrease of 1.7%. [11] - **Flake caustic soda market price**: On December 12, 2025, prices in most regions remained unchanged. In the Southwest, Central China, and East China regions, prices dropped by 50 yuan/ton, with decreases of 1.5%, 1.6%, and 1.5% respectively. [12] - **Caustic soda grade/regional spread**: On December 12, 2025, all spreads remained unchanged compared to the previous day. [12] - **Caustic soda futures price/month spread**: On December 12, 2025, the 05 contract increased by 4 yuan/ton (0.18%), the 09 contract decreased by 16 yuan/ton (- 0.68%), and the 01 contract increased by 8 yuan/ton (0.38%). The month - spreads also changed accordingly. [13] 3.2 This Week's Important Information and Next Week's Focus Events 3.2.1 This Week's Important Information - Bullish information: Chlor - alkali profits have declined, and the overall market pricing is relatively pessimistic. [14] - Bearish information: Not provided in the document 3.2.2 Next Week's Important Events to Watch - Observe the downstream demand, the off - season situation of non - aluminum industries, and the alkali - stocking rhythm of aluminum plants. [14] 3.3 Disk Interpretation 3.3.1 Price - Volume and Capital Interpretation - Unilateral trend and capital flow: This week, the caustic soda price continued to decline, reaching a new low for the year. However, there is no obvious upward driving force in both fundamentals and sentiment. [14] - **Reasons**: Caustic soda production remains at a high level, increasing supply pressure, and non - aluminum demand is expected to weaken. [16] 3.3.2 Basis and Month - Spread Structure - Shandong Jinling's 32% caustic soda (converted to 100% purity) is priced at 2156 yuan/ton, with a premium of 60 yuan over the 01 contract and 46 yuan/ton over the 03 contract. Alkali plant inventories are at a high level, and the fundamentals lack support. [17] 3.4 Valuation and Profit Analysis 3.4.1 Upstream - Downstream Profit Tracking in the Industrial Chain - As the caustic soda price falls, overall chlor - alkali profits have declined. The liquid chlorine price is relatively neutral, at 100 yuan/ton in both Jiangsu and Shandong. [27] 3.4.2 Import - Export Profit Tracking - In terms of exports, the Southeast Asian CFR price is 430 US dollars/ton, remaining stable for now.
