1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints of the Report PVC - This week, PVC production slightly decreased due to more-than-expected device overhauls. Next week, with some overhauled devices resuming production, production is expected to increase slightly. Export orders increased slightly this week, and this month's domestic apparent demand growth rate may be lower than expected. This week, the old sample of PVC inventory decreased by 28,000 tons, but it is expected to slightly accumulate next week. The upstream comprehensive profit slightly deteriorated, and the export profit also slightly worsened. The downstream demand is weak, and the overall domestic demand is not strong [6][9][10]. Caustic Soda - This week, the production of caustic soda decreased slightly due to more overhaul devices, but the overall production remained at a high level. It is expected to increase slightly next week. The apparent demand this week was around 724,900 tons, and it is estimated to be about 775,300 tons next week. The national inventory slightly accumulated this week, and it is estimated to accumulate next week based on static data, but may slightly decrease if production falls short of expectations. The comprehensive profit of Shandong chlor-alkali plants with external sales of liquid chlorine improved, while that of enterprises with supporting PVC slightly deteriorated [103][106]. 3. Summaries According to Relevant Catalogs PVC 3.1 Spot Market - This week, the overall PVC price slightly decreased, while the caustic soda price remained stable, and the price of Shandong liquid chlorine rebounded.

1. Report Industry Investment Rating No information about the report industry investment rating is provided in the content. 2. Core Viewpoints of the Report - The fundamentals of the PVC industry are weak, with a pattern of strong supply and weak demand in China. The export outlook is turning weaker, and domestic demand is poor, making it difficult to reverse the situation of oversupply. - In the short - term, the valuation has declined to a low level, but it still cannot support the supply - demand situation that is weaker than in the first half of the year. The slowdown in inventory accumulation and the strong sentiment in the black market are supporting prices. - In the medium - term, there are opportunities for short - selling on rallies, as the supply - demand pattern is expected to be poor after the new device is put into production, and real estate demand continues to decline. [11] 3. Summary by Relevant Catalogs 3.1.

1. Report Industry Investment Rating There is no information regarding the report industry investment rating in the provided content. 2. Core Viewpoints of the Report - Macro: In September, China's economic data was gradually released, the US government continued to be in a "shutdown" state with key economic data missing, and Fed officials gradually signaled interest - rate cuts [4]. - Supply - demand: In the Jiangsu and Zhejiang regions, some plants are expected to enter maintenance, tightening market supply, and with the approaching demand procurement cycle, liquid caustic soda prices are expected to rise steadily. In Shandong, with the shipment of orders from other provinces and the decline in enterprise inventories, some enterprises may continue to raise prices. The low - concentration caustic soda market is expected to rise slightly, while the high - concentration caustic soda may be sold at lower prices [4]. - Overall logic: Recently, the spot price in Shandong has been relatively strong, but there is a certain expectation of production cuts in the alumina industry. Coupled with the improvement of enterprise profits due to the recovery of liquid chlorine prices, the caustic soda 2601 contract will continue to be under pressure and run weakly [4]. - Strategy advice: For the caustic soda 2601 contract, the upper reference pressure level is 2600 yuan/ton, and the lower support level is 2300 yuan/ton [4]. 3. Summary According to the Directory 3.1 Market Review - **Spot market**: From 2024/10 to 2025/10, data on the market prices of 32% ion - membrane caustic soda in Shandong, Jiangsu, and Zhejiang, the price difference between 50% and 32% caustic soda in Shandong, the price difference of 32% caustic soda between Shandong and Jiangsu, and Shandong and Zhejiang were presented. Also, data on the basis, the market prices of flake caustic soda (99%) in Shandong and the northwest, the market prices of 32% ion - membrane caustic soda and raw salt in Shandong, and the market prices of 32% ion - membrane caustic soda and liquid chlorine in Shandong were shown [9][12]. - **Futures market**: From 2024/10 to 2025/10, data on the futures closing prices of caustic soda, alumina, PVC, and soda ash, the number of caustic soda warehouse receipts were presented [15]. - **Weekly market review (20251010 - 20251016)**: The prices, price changes, and price change rates of products such as raw salt, liquid caustic soda, flake caustic soda, liquid chlorine, alumina, viscose staple fiber, and lithium hydroxide were provided. For example, the price of 32% ion - membrane caustic soda in Shandong increased from 815 yuan/ton to 830 yuan/ton, with a growth rate of 1.84%, and the price of liquid chlorine in Shandong increased from - 100 yuan/ton to 50 yuan/ton, with a growth rate of 150% [18]. 3.2 Market Analysis - **Supply side - Output and operating rate**: From 20251010 - 1016, the average capacity utilization rate of China's caustic soda sample enterprises with a capacity of 200,000 tons and above was 81.4%, a decrease of 2.6% compared to the previous period. Loads in the northwest, north, east, south, and northeast regions all declined [20]. - **Supply side - Enterprise maintenance situation**: Enterprises in various regions such as Henan, Shandong, Tianjin, and Liaoning have maintenance plans, with different maintenance times and durations [22]. - **Downstream demand**: In the alumina industry, due to high profits in the electrolytic aluminum industry and shrinking profits in the alumina industry, electrolytic aluminum plants have made small - scale purchases for replenishment, but the transaction price is still declining. The capacity utilization rate of the viscose staple fiber industry decreased by 1.02% week - on - week [26]. - **Inventory**: As of 20251016, the factory inventory of fixed liquid caustic soda sample enterprises with a capacity of 200,000 tons and above in China was 403,300 tons (wet tons), a decrease of 4.25% compared to the previous period and an increase of 13.83% compared to the same period last year. The inventory situation varied in different regions [29]. - **Liquid chlorine**: As of October 16, 2025, the average price of liquid chlorine in Shandong was - 86 yuan/ton, a week - on - week increase of 14.43%. The liquid chlorine market is expected to be stable with a downward trend in the near future. As of October 17, 2025, China's PVC capacity utilization rate was 76.69%, and it is expected to rise to 78.47% this week [33]. - **Chlor - alkali cost - profit**: From 20251010 - 20251016, the average weekly gross profit of Shandong chlor - alkali enterprises was 394 yuan/ton, a week - on - week increase of 15.54% [34].

Report Industry Investment Rating No relevant content provided. Core Views - PVC: Supply-demand pressure is high, and the fundamental supply-demand contradiction is difficult to ease. The futures and spot prices are both weakening. Supply is expected to increase as some maintenance enterprises resume production next week. The peak season shows no obvious improvement, and downstream product enterprises perform averagely. The export market is affected by India's anti-dumping tax, with a wait-and-see attitude. The cost side provides bottom support, and the market is expected to remain under pressure, with a bearish view on rebounds [3]. - Caustic Soda: The price of downstream alumina continues to decline, and the industry's profit is shrinking with increasing losses. Some enterprises have cut production passively, so the demand-side support for caustic soda is weak. In the medium to long term, there is demand support as alumina has many planned projects in Q1 next year, which may lead to concentrated stockpiling in Q4 this year. After the National Day, non-aluminum industries may have purchasing intentions due to low prices. However, in the short term, the supply of caustic soda is increasing, while downstream demand is average, so the market sentiment is weak, and the price lacks support. A bearish view is recommended for short-term trading, and the downstream replenishment rhythm needs to be monitored [4]. Summary by Directory Caustic Soda - **Price and Market Trends**: The macro environment has weakened, and the caustic soda market has been affected by factors such as high开工 rates, inventory changes, and alumina demand. The futures price has fluctuated, and the spot price has shown a downward trend in some periods [8]. - **Supply**: The national average weekly weighted开工 rate of sample enterprises decreased to 85.45% from 88.24% last week, and the caustic soda production decreased by 3.17% to 82.43 tons. Many enterprises have carried out maintenance or faced unexpected failures [27]. - **Demand**: The demand from the alumina industry is weak due to its poor profitability. However, new alumina projects are expected to drive demand growth in the future. Non-aluminum industries may increase purchases after the National Day [4]. - **Export**: The export volume decreased in August but the export profit increased in September [56]. Polyvinyl Chloride (PVC) - **Price and Market Trends**: The PVC futures price has been on a downward trend due to weak supply-demand drivers and a poor commodity market atmosphere. The spot price has also weakened [63]. - **Supply**: The overall开工 rate of PVC powder decreased to 75.14% this week, with significant decreases in both calcium carbide and ethylene methods. Many enterprises have carried out maintenance [85]. - **Demand**: The two major downstream industries, profiles and pipes, face great pressure, and the real estate industry continues to have a negative impact on demand. The downstream orders are lower than the average of the past five years, and the inventory is high [93]. - **Inventory**: The inventory has been increasing, and the total inventory is at the highest level in recent years [101]. - **Export**: The net export volume decreased in August. The import volume in August 2025 was 1.24 tons, and the export volume was 28.41 tons [113][119].

1. Report Industry Investment Rating - Not provided in the given content 2. Core View of the Report - The demand for propylene lacks support, and its upward movement is weak. Although the propylene price has stopped falling after reaching a low level, the supply - demand relationship remains weak, and the cost - side guidance is not strong, so the price may continue to be weak. Attention should be paid to the impact of the intensification of Sino - US trade frictions on the propane supply on the cost side [2] 3. Summary by Relevant Catalogs 3.1 Market News and Important Data - Propylene: The closing price of the main propylene contract is 6106 yuan/ton (+27), the spot price in East China is 6190 yuan/ton (-25), and in North China is 6215 yuan/ton (-45). The basis in East China is 84 yuan/ton (-52), and in North China is 109 yuan/ton (-72). The operating rate is 74% (-1%), the difference between China's propylene CFR and Japan's naphtha CFR is 226 US dollars/ton (+4), the difference between propylene CFR and 1.2 propane CFR is 132 US dollars/ton (-11), the import profit is - 400 yuan/ton (-6), and the in - plant inventory is 43390 tons (-1520) [1] - Propylene downstream: The operating rate of PP powder is 39% (-1.03%), and the production profit is - 85 yuan/ton (+0); the operating rate of propylene oxide is 68% (-4%), and the production profit is - 51 yuan/ton (-33); the operating rate of n - butanol is 90% (+2%), and the production profit is 85 yuan/ton (+28); the operating rate of octanol is 92% (-4%), and the production profit is 103 yuan/ton (+32); the operating rate of acrylic acid is 75% (-8%), and the production profit is 1205 yuan/ton (+18); the operating rate of acrylonitrile is 79% (+0%), and the production profit is - 673 yuan/ton (+47); the operating rate of phenol - acetone is 78% (+0%), and the production profit is - 526 yuan/ton (+0) [1] 3.2 Market Analysis - Supply side: The 600,000 - ton PDH unit of Bohai Petrochemical and the 650,000 - ton cracking unit of Yulong Petrochemical have stopped, while the 450,000 - ton PDH unit of Tianhong has restarted, and the PDH unit of Haiwei has the expectation of restarting. Coupled with the resumption of production of some major manufacturers in Shandong before the festival, the restart of PDH continues to suppress the propylene supply side [2] - Demand side: When the propylene price drops to a phased low, downstream buyers start to purchase at low prices, but the purchasing enthusiasm is not high, and the demand lacks continuous support. The overall downstream operating rate has declined. For propylene oxide, Lihuayi and Jinling have stopped for maintenance, and the PO unit of Hangjin Technology has a shutdown plan, resulting in a decline in the PO operating rate. The demand on the PP side is also difficult to improve, and the operating rate of PP powder has declined slightly. The operating rate of acrylic acid has declined significantly [2] - Cost side: International oil prices continue to decline under pressure due to weak demand and tariff disturbances. The price of external propane has rebounded slightly but is still weak. The cost side of propylene continues to drag down the propylene market [2] 3.3 Strategy - Unilateral: Wait and see - Inter - period: Sell high and buy back for the PL01 - 02 spread - Inter - variety: None [3] 3.4 Catalog - related Charts - **Propylene basis structure**: Includes charts of the closing price of the main propylene contract, the basis in East China and North China, the 01 - 05 contract, and the market prices in East China and Shandong [6][9][11] - **Propylene production profit and operating rate**: Includes charts of the difference between China's propylene CFR and Japan's naphtha CFR, propylene capacity utilization rate, PDH production gross profit and capacity utilization rate, MTO production gross profit, methanol - to - olefins capacity utilization rate, propylene naphtha cracking production gross profit, and crude oil main refinery capacity utilization rate [15][17][23] - **Propylene import and export profit**: Includes charts of the price differences between South Korea's FOB and China's CFR, Japan's CFR and China's CFR, Southeast Asia's CFR and China's CFR, and propylene import profit [30][32] - **Propylene downstream profit and operating rate**: Includes charts of the production profit and operating rate of PP powder, propylene oxide, n - butanol, octanol, acrylic acid, acrylonitrile, and phenol - acetone [38][40][43] - **Propylene inventory**: Includes charts of propylene in - plant inventory and PP powder in - plant inventory [62]
