Report Industry Investment Rating No information provided in the report. Core Viewpoints of the Report - The current core contradiction in the market remains the pattern of "high supply, high inventory, and weak demand." The fundamental driving force is limited, and the short - term trend of the futures market is weak, expected to maintain a volatile operation. Follow - up attention should be paid to macro - sentiment changes and industry capacity adjustment [9][40]. - In terms of operation, it is recommended to wait and see for single - side trading as there are no obvious trend opportunities; no arbitrage opportunities are available; for options, consider selling the wide - straddle strategy opportunistically to collect time value [40]. Summary by Relevant Catalogs 1. Market Review - Last week, the price of the main contract SA2601 of soda ash fluctuated within the range of 1,283 - 1,352 yuan/ton. As of the afternoon close on September 19, 2025, the main contract SA2601 of soda ash futures rose by 28 yuan/ton, a weekly increase of 2.17%, closing at 1,318 yuan/ton [6]. 2. Soda Ash Supply and Demand Situation 2.1 Production and Capacity Analysis - As of September 18, 2025, the weekly domestic soda ash production was 745,700 tons, a month - on - month decrease of 15,400 tons, a decline of 2.02%. Light soda ash production was 328,000 tons, a month - on - month decrease of 11,400 tons; heavy soda ash production was 417,700 tons, a month - on - month decrease of 4,000 tons. Individual enterprise shutdowns for maintenance and equipment problems led to the supply decline [10]. - Last week, the comprehensive capacity utilization rate of soda ash was 85.53%, a month - on - month decline of 1.76%. Among them, the ammonia - soda process capacity utilization rate was 88.87%, a month - on - month decline of 1.97%; the co - production process capacity utilization rate was 75.53%, a month - on - month decline of 1.86%. The overall capacity utilization rate of 15 enterprises with an annual production capacity of one million tons or more was 87.27%, a month - on - month decline of 1.03% [12]. 2.2 Soda Ash Inventory Analysis - As of September 18, 2025, the total inventory of domestic soda ash manufacturers was 1,755,600 tons, an increase of 8,500 tons from the previous Monday, a growth rate of 0.49%. Among them, light soda ash inventory was 749,500 tons, a month - on - month increase of 3,200 tons; heavy soda ash inventory was 1,006,100 tons, a month - on - month increase of 5,300 tons. Compared with the previous Thursday, it decreased by 41,900 tons, a decline of 2.33%. The inventory last year was 1,398,800 tons, a year - on - year increase of 356,800 tons, a growth rate of 25.51% [14]. 2.3 Shipment Situation Analysis - On September 18, it was reported that the weekly shipment volume of Chinese soda ash enterprises was 787,600 tons, a month - on - month increase of 0.25%; the overall soda ash shipment rate was 105.62%, a month - on - month increase of 2.39 percentage points. The weekly soda ash supply decreased slightly, and the shipments of individual enterprises were good, with the overall production - sales rate slightly easing [17]. 2.4 Profit Analysis - On September 18, 2025, the theoretical profit of the ammonia - soda process for soda ash in China was - 36.75 yuan/ton, a month - on - month decline of 0.45 yuan/ton. During the week, the price of raw salt on the cost side remained stable, the price of coke increased slightly, and the cost side increased; the price of soda ash remained stable, so the profit of the ammonia - soda process fluctuated downward [20]. - As of September 18, 2025, the theoretical profit (double - ton) of the co - production process for soda ash in China was - 70.50 yuan/ton, a month - on - month decline of 16 yuan/ton. During the week, the price of raw salt remained stable, the price of coal increased, the cost side strengthened; the price of soda ash fluctuated steadily, and the by - product ammonium chloride decreased slightly, so the double - ton profit of the co - production process declined [24]. 3. Downstream Industry Situation 3.1 Float Glass Industry - As of September 18, 2025, the daily output of national float glass was 160,200 tons, the same as on the 11th. The weekly output of national float glass from September 12 - 18, 2025 was 1,121,200 tons, the same as the previous week, a year - on - year decrease of 4.04% [28]. - As of September 18, 2025, the total inventory of national float glass sample enterprises was 60,908,000 weight cases, a month - on - month decrease of 675,000 weight cases, a month - on - month decrease of 1.10%, a year - on - year decrease of 18.56%. The inventory days were 26 days, a decrease of 0.3 days from the previous period [29]. 4. Spot Market Situation - The price of 5500 - calorie steam coal increased by 10 yuan/ton, a growth rate of 1.46%; the price of well - mine salt in the East China region remained unchanged; the price of light soda ash in the Central China region increased by 20 yuan/ton, a growth rate of 1.77%; the price of float glass in China increased by 2 yuan/ton, a growth rate of 0.17%; the price of ammonium chloride (dry ammonium) in Henan decreased by 20 yuan/ton, a decline of 5%; the price of synthetic ammonia in Jiangsu decreased by 62 yuan/ton, a decline of 2.79% [37][39]. 5. Comprehensive Analysis - Last week, the soda ash market showed an overall volatile pattern. The supply - side pressure still exists. Although there may be fluctuations in individual devices during the week, the overall industry operating rate remains relatively high, and the production pressure has not been fundamentally alleviated. The demand side is weak, with downstream glass and photovoltaic industries purchasing on a just - in - time basis, limited new order increments, and strong market wait - and - see sentiment. Although the enterprise inventory has decreased compared with the previous week, the absolute level is still at a historically high level, reflecting the weak terminal demand. The profit situation is not optimistic, with both the ammonia - soda process and the co - production process continuing to operate at a loss, and the cost support is limited [40].

Report Industry Investment Rating - Not provided in the document Core Viewpoints - Urea: The domestic urea fundamentals face multiple factors such as rising supply, continuous realization of export demand, transfer of enterprise inventory to the middle - downstream and ports, and insufficient domestic demand support. After the Indian tender results are announced, the short - term market positive factors are exhausted, and the 01 contract will still run weakly. In the medium - term, there will be a game stage among various factors. In the long - term, the pressure of new production capacity in the industry is still high [4]. - Soda Ash: Recently, the changes in indicators such as supply, demand, and inventory of soda ash are relatively limited, and the fundamental driving force is insufficient. Subsequently, the warming of macro - sentiment and anti - involution themes will continue to boost market sentiment. The futures price shows obvious characteristics of a phased bottom, but currently does not have the momentum for a trend - based upward movement. It is recommended to continue to adopt a wide - range shock thinking [5]. - Glass: The supply - demand contradiction of glass has not been significantly reversed, and the industry has different expectations for the future. The glass factory has a certain price - holding mentality, and the short - term glass futures price has obvious characteristics of a phased bottom, but currently there is insufficient new driving force in the market. If external factors such as macro - warming and anti - involution are combined with the realization of peak - season demand, the glass futures price may be significantly boosted [6][7]. Summary by Directory 1. Futures Market and Raw Material Situation in the Industrial Chain - Futures Prices: As of September 12, the weekly change of the urea main contract was - 3.2%, the soda ash main contract was + 0.16%, and the glass main contract was + 1.2% [13]. - Related Futures Varieties: This week, the trends of related varieties were differentiated, with urea being the weakest and glass being the strongest [15]. - Coal Prices: The prices of Qinhuangdao Youhun steam coal (5500), Shaanxi Yulin bituminous coal fines (Q5500), Yangquan anthracite washed small lumps, and Yangquan anthracite washed medium lumps showed little change from September 5 - 11 [19]. - LNG Prices: The LNG prices of some domestic regions such as Inner Mongolia Huineng and Inner Mongolia Xingsheng showed certain fluctuations from September 5 - 11 [23]. - Two - Alkali Raw Material Salt: This week, the raw salt price remained basically stable [24]. - Ammonia Prices: The price of Shandong synthetic ammonia decreased by 1.39% week - on - week from September 4 - 11 [27]. 2. Urea: Market Positive Factors Exhausted, Short - Term Weak Operation of the Futures Market - Spot Prices: This week, the urea spot market price showed a weak trend. The prices in Shandong and Henan decreased by 20 yuan/ton and 40 yuan/ton respectively week - on - week [30]. - Production: This week, the urea production level increased slightly, with the industry's operating rate rising by 1.23 percentage points to 79.34%. The operating rates of small and large - granular urea increased by 1.01 and 2.13 percentage points respectively [34][40]. - Output: This week, the daily urea output fluctuated around 180,000 tons, and the weekly output increased by 1.58% week - on - week [43][45]. - Inventory: This week, the urea enterprise inventory increased by 3.44% to 1.1327 million tons, and the port inventory decreased by 11.52% to 549,400 tons [46]. - Downstream Demand: This week, the operating rate of melamine decreased by 3.6 percentage points to 55.38%, the operating rate of adhesives decreased by 2.27 percentage points to 48.75%, and the price of vehicle - use urea decreased significantly [58][62][65]. - International Market: The Indian tender results were announced, and the procurement quantity did not exceed expectations. The subsequent supply quantity from China needs to be monitored [71]. - Related Products: This week, the prices of some phosphate fertilizer products declined, and the potash fertilizer price remained stable [73]. 3. Soda Ash: Limited Changes in Supply and Demand, Focus on the Impact of External Factors - Spot Prices: This week, most of the soda ash spot quotations were stable, and individual regions still showed a downward trend. The mainstream average prices of light and heavy soda ash in some regions changed slightly week - on - week [82][85]. - Production: This week, the soda ash production level increased slightly, with the industry's operating rate rising by 1.07 percentage points to 87.29%. The weekly output increased by 1.25% to 761,100 tons [91][97]. - Inventory: This week, the soda ash enterprise inventory was 1.7975 million tons, a week - on - week decrease of 1.35%. The enterprise inventory has been decreasing for three consecutive weeks, but the decrease was very limited [102][110]. - Import and Export: In July, China's soda ash export volume was 161,300 tons, a month - on - month increase of 2.66% [111]. - Cost and Profit: This week, the cost center of soda ash continued to decline slightly [114]. 4. Glass: Cautious Industry Mentality, Focus on the Quality of Future Demand - Futures Prices: This week, the glass futures price showed a weak shock trend, and the closing price of the main 01 contract on Friday was 1,180 yuan/ton, a weekly increase of 1.2% [6]. - Spot Prices: This week, the glass spot price rebounded locally, and the average price of the domestic float glass market on Friday was 1,164 yuan/ton, an increase of 8 yuan/ton from last Friday [6]. - Supply: This week, one production line of the glass industry produced finished products, and the supply level increased slightly. The daily melting volume in production as of Friday was 160,200 tons per day, an increase of 600 tons per day from last week [6]. - Inventory: This week, the glass enterprise inventory was 61.583 million tons, a week - on - week decrease of 2.33%. The inventory fluctuation range was limited, and the de - stocking trend was not obvious [6]. - Demand: Currently, the glass demand has not shown the characteristics of the peak season, but the purchasing sentiment of the middle - downstream was acceptable this week, and the glass factory orders increased slightly. However, the demand is still differentiated between regions, and the terminal demand has not been substantially improved [6].

1. Report Industry Investment Rating - No information provided 2. Core Viewpoints of the Report - SH2601 fluctuated slightly, closing at 2,576 yuan/ton. The caustic soda capacity utilization rate increased by 1.8% week-on-week to 84.2% last week. The alumina开工率 decreased by 1.2% week-on-week to 84.38%, the viscose staple fiber开工率 increased by 1.08% week-on-week to 87.10%, and the printing and dyeing开工率 increased by 0.9% week-on-week to 65.63%. The liquid caustic soda factory inventory increased by 2.17% week-on-week to 387,800 tons last week. One set of equipment in Central China and two sets in the Northwest are scheduled for maintenance this week, which may lead to a slight decline in capacity utilization. There are many maintenance plans for chlor-alkali plants in September, and the industry's supply pressure is expected to be relieved. Some alumina enterprises have short-term elastic production, but due to the considerable industry profits, the production enthusiasm of alumina enterprises is still high. Non-aluminum demand has a seasonal increase, and some previously shut-down plants have restarted. The inventory pressure of liquid caustic soda is not large, and attention should be paid to the subsequent inventory removal rhythm. In terms of spot, the price of liquid caustic soda in Shandong is expected to remain stable or rise slightly in the short term. In terms of futures, the high-level of caustic soda warehouse receipts has decreased, but the fourth-quarter production capacity expectation still suppresses the futures price, and the main contract may continue to be at a discount. Technically, SH2601 should pay attention to the support around 2,530 [1] 3.

1. Report Industry Investment Rating - No information provided 2. Core Viewpoints of the Report - Supply is expected to tighten as more chlor - alkali plants are scheduled for maintenance in September, and the capacity utilization rate is predicted to continue to decline [1]. - Alumina industry's strong profit and production intention support caustic soda demand, and non - aluminum demand has a seasonal increase with some idle plants restarting [1]. - Shandong's liquid caustic soda inventory pressure is low. Spot prices have room to rise due to improved supply - demand. Future production expectations will still suppress far - month contract prices, and near - month contracts are expected to be stronger than far - month contracts [1]. - Technically, attention should be paid to the resistance around 2760 for SH2601 [2]. 3.
