1. Report Industry Investment Rating - There is no information provided about the industry investment rating in the report. 2. Core Viewpoints of the Report - Affected by the unloading of imported ships, the market's concerns about supply intensified, but the situation later eased. The futures price showed a pattern of rising first and then falling, with the monthly spread continuing to rise and the basis strengthening rapidly. The current spot market still has a high - inventory pattern, and the price difference between ports and inland areas has slightly strengthened [11]. - The domestic operating rate has declined from a high level, coal prices have strengthened leading to higher costs, and short - term imports have been affected with lower arrivals. The port olefin operating rate has remained flat, while the overall domestic olefin operating rate is at a high level. Traditional demand has weakened overall, with the operating rates of dimethyl ether and formaldehyde rising and the rest falling [11]. - The basis has quickly recovered from a low level to near 0, and the 1 - 5 spread has continued to rise due to near - term import impacts. Coal - to - methanol profits are still relatively high, but downstream profits are generally at a medium - to - low level, and methanol valuation is moderately high [11]. - Port inventories have decreased due to lower import arrivals, while enterprise inventories have increased slightly but are at a low level compared to the same period last year. The market logic is that short - term import disruptions have made port prices stronger than inland prices, leading to an increase in the basis and monthly spread, and an absolute price that first rose and then fell [11]. - Overall, the demand during the peak season has fallen short of expectations, the domestic inventory is high, and the pattern of weak reality remains unchanged. Short - term port pressure has been relieved due to the delayed unloading of imported goods. The potential upward driver for future prices lies in the expected improvement brought by winter gas restrictions. Currently, the price has basically reflected the weak - reality pattern. In the future, attention should be focused on supply - side disruptions, and opportunities for long positions and 1 - 5 positive spreads should be considered on dips [11]. 3. Summary by Directory 3.1 Week - to - Week Assessment and Strategy Recommendation - **Weekly Summary**: The futures price showed a pattern of rising first and then falling due to import impacts. The domestic operating rate was 87.42%, declining from a high level. Coal prices strengthened, and short - term imports were affected with lower arrivals. The port olefin operating rate was 88.08%, remaining flat. Traditional demand weakened overall. The basis recovered to near 0, and the 1 - 5 spread rose. Coal - to - methanol profits were still high, but downstream profits were at a medium - to - low level. Port inventories decreased by 5.18 tons to 149.14 tons, and enterprise inventories increased by 2.05 tons to 35.99 tons [11]. - **Market Logic**: Short - term import disruptions made port prices stronger, leading to an increase in the basis and monthly spread, and an absolute price that first rose and then fell. Import unloading was delayed, leading to lower arrivals and a reduction in port inventories. Domestic supply decreased slightly, and coal prices continued to rebound, causing a decline in coal - to - methanol profits. Demand remained weak [11]. - **Strategy**: Consider long positions and 1 - 5 positive spreads on dips [11]. 3.2 Futures and Spot Market - **Basis and Spread**: Near - term import disruptions have strengthened the 1 - 5 spread, and the basis has recovered to near 0 [20]. - **Trading Volume and Open Interest**: There has been an increase in open interest and a decline in price [23]. 3.3 Profit and Inventory - **Production Profit**: Coal - to - methanol profits are good [41]. - **Port Inventory**: Port inventories are at a historical high [42]. - **Regional Inventory**: Factory inventories are at a low level compared to the same period last year [44]. 3.4 Supply Side - **Capacity**: There are new methanol production capacities in the northwest region, with different raw materials and expected commissioning times [53]. - **Upstream Production and Operating Rate**: Supply has returned to a high level [55]. - **Import Volume**: Import volumes and arrivals have been affected, with different import situations from countries such as Iran, Oman, and Saudi Arabia [62][71]. - **International Price Difference**: There are fluctuations in import profits and price differences between China and other regions [74]. - **Domestic Freight**: There are data on domestic methanol freight [82]. 3.5 Demand Side - **Demand Projection**: There are consumption and inventory data for methanol [86]. - **Methanol - to - Olefins**: There are data on olefin operating rates, profits of related enterprises, and relevant price differences [88][92][99]. - **PP Production Profits by Different Processes**: There are data on production profits of PP by oil - based, coal - based, PDH - based, and externally - sourced propylene - based processes [96]. - **MTO - Related Price Differences**: There are data on price differences such as PP - 3MA and LL - 3MA [99]. - **Formaldehyde and Dimethyl Ether Operating Rates and Profits**: There are data on the operating rates and profits of formaldehyde and dimethyl ether [111]. - **Downstream Inventory**: There are data on downstream operating rates, profits, and inventories [114]. - **Related Product Ratios**: There are data on ratios between methanol and other products such as urea, INE crude oil, and动力煤 [117]. 3.6 Options - Related - **Methanol Options**: There are data on option trading volume, open interest, PCR, and volatility [122][124]. 3.7 Industry Structure Chart - There are charts showing the methanol industry chain and research framework analysis [127][129].

1. Report Industry Investment Rating No information provided. 2. Core Viewpoints of the Report - The fundamental situation of the pig market is characterized by an oversupply. Although the price of fat pigs is higher than that of standard pigs, the secondary fattening is unlikely to gain momentum due to the pessimistic market expectations. As a result, the rebound space for near - term spot prices is limited. The near - month futures contracts will mainly consume the premium, and the far - month contracts will continue to be devalued. The overall strategy is to sell on rebounds [11][12]. 3. Summary According to the Directory 3.1. Weekly Assessment and Strategy Recommendation - **Spot Market**: Affected by factors such as reluctance to sell at low prices, increased consumption after cooling, and more secondary fattening, domestic pig prices rebounded slightly from the low level last week. However, the cautious market limited the rebound space. With abundant supply, the average weight increased after slaughter, and the price difference between fat and standard pigs continued to rise seasonally. In terms of regional prices, the average price in Henan rose by 0.14 yuan to 11.4 yuan/kg, that in Sichuan fell by 0.06 yuan to 10.9 yuan/kg, and that in Guangdong fell by 0.3 yuan to 11.52 yuan/kg. The theoretical and planned出栏量 remains large, and the support from secondary fattening may be short - term. In October, there is no obvious consumption theme, and the short - term oversupply may continue. The spot market will generally maintain a weak oscillation, with phased support from reduced supply at the end of the month and secondary fattening [11][22]. - **Supply Side**: In August, the official sow inventory was 40.36 million heads, a slight month - on - month decrease of 60,000 heads (0.1%), still 3.5% more than the normal level. The continuous increase in sow production capacity since last year may lead to a weak fundamental situation this year. However, there is a strong expectation of forced production capacity reduction from the policy side, which may improve the supply situation next year. The implementation of policy - driven production capacity reduction in the coming months needs attention. Data shows that the sow inventory decreased by 0.33% in September according to Steel Union and 0.84% according to Yongyi, indicating a slow pace of production capacity reduction. From the perspective of piglet data, there is a significant increase in basic supply from now to March next year. However, the continuous weight reduction of group farms from June to August led to some pre - emptive supply, which may partially offset the current supply pressure. Near - term data shows that the slaughter volume has remained high after the National Day, the frozen meat inventory has continued to rise, and the average trading weight of live pigs is larger than the same period last year and has increased month - on - month, indicating a short - term oversupply situation [11]. - **Demand Side**: There may be marginal improvement in demand due to the start of school in early September, cooling in the middle and late September, and stockpiling for the Mid - Autumn Festival and National Day. However, after the National Day, demand will enter a downturn again until it gradually improves with the arrival of cold weather and the Spring Festival [11][59]. - **Trading Strategy**: - Unilateral: Short the 11 - 03 contracts on rallies, with a profit - loss ratio of 2:1 and a recommended period of 0.5 - 1 months. The core driving factors are supply, weight, and consumer demand [13]. - Arbitrage: Conduct reverse arbitrage on the 3 - 7 and 3 - 9 contracts, with a profit - loss ratio of 2:1 and a recommended period of 2 months. The driving factors are policies, weight, basic supply, and the price difference between fat and standard pigs [13]. 3.2. Futures and Spot Markets - **Spot Price Trend**: The domestic pig price rebounded slightly last week but was limited by the cautious market. The average weight increased after slaughter, and the price difference between fat and standard pigs rose seasonally. The theoretical and planned出栏量 is large, and the short - term oversupply may continue. The spot market will maintain a weak oscillation [22]. - **Basis and Spread Trends**: The spot price rebounded slightly, but the futures market had a weak expectation. The basis converged, and the month - spread still favored reverse arbitrage [25]. - **Prices of Piglets and Sows**: Relevant price trend charts are provided, but no specific analysis content is given. 3.3. Supply Side - **Reproductive Sows and Changes**: In August, the official sow inventory was 40.36 million heads, slightly down month - on - month, but still higher than the normal level. There is a strong expectation of policy - driven production capacity reduction, but the current pace of production capacity reduction is slow [33]. - **Inventory and Slaughter**: From the piglet data, there is an increase in basic supply from now to March next year. The continuous weight reduction of group farms from June to August led to pre - emptive supply, which may offset some supply pressure. The short - term market is in an oversupply situation [43][50]. - **Sow Culling and Sales**: Relevant data charts are provided, but no specific analysis content is given. - **Theoretical Slaughter Volume**: The basic supply from now to March next year increases, but the pre - emptive supply from group farms may offset some pressure [43]. - **Proportion of Small and Large Pigs in Slaughter**: The low proportion of small pigs in slaughter indicates little impact from diseases, and the low proportion of large pigs indicates a limited number of fat pigs [46]. - **Trading and Post - slaughter Average Weight**: After the National Day, the slaughter volume remained high, the frozen meat inventory continued to rise, and the average trading weight of live pigs was larger than the same period last year and increased month - on - month, indicating a short - term oversupply [50]. - **Import and Pig Feed Month - on - month**: Relevant data charts are provided, but no specific analysis content is given. - **Secondary Fattening and Pen Utilization**: Relevant data charts are provided, but no specific analysis content is given. 3.4. Demand Side - **Slaughter Volume**: There may be marginal improvement in demand before the National Day, but it will enter a downturn after the National Day and gradually improve with the arrival of cold weather and the Spring Festival [59]. - **Slaughter Operating Rate and Gross Margin**: Relevant data charts are provided, but no specific analysis content is given. - **Price Difference and Price - Volume Relationship**: Relevant data charts are provided, but no specific analysis content is given. - **Fresh - Frozen Price Difference and Fresh Sales Rate**: Relevant data charts are provided, but no specific analysis content is given. 3.5. Cost and Profit - **Cost and Breeding Profit**: Due to factors such as feed cost and efficiency improvement, the cost has been continuously decreasing. However, the pig price is the weakest in the same period in recent years, and there has been an overall loss this year despite the low cost [70]. 3.6. Inventory Side - **Cost and Breeding Profit**: The frozen meat inventory is in a state of slow recovery and passive inventory accumulation [75].

1. Report Industry Investment Rating - No industry investment rating information is provided in the report. 2. Core Viewpoints of the Report - For PX, last week's PXN expanded passively due to the pressure on the naphtha spread. PX followed the decline of crude oil. With high PX load, short - term PTA maintenance, and new PTA device commissioning expectations, PX inventory is difficult to deplete. Currently, PXN is at a neutral level and mainly follows crude oil fluctuations. Short - term observation is recommended [11]. - For PTA, last week's PTA processing fee was under pressure due to commissioning expectations, and it mainly followed the passive decline of crude oil. In the future, supply maintenance will decrease, and inventory will gradually accumulate. The processing fee is difficult to expand. The demand side of polyester and chemical fiber has low inventory and profit pressure, and the load is expected to remain high, but the terminal shows signs of weakness. Short - term observation is recommended [12]. - For MEG, the load of domestic and overseas devices is at a high level, the domestic supply is high, the import volume has rebounded, and the port has started to accumulate inventory. In the fourth quarter, with the concentrated arrival of imports and the expected continuous high domestic load, combined with the gradual commissioning of new devices, inventory accumulation is expected to continue. The current valuation is still relatively high, and there is pressure to continuously compress the valuation in a weak pattern. It is recommended to short on rallies [13]. 3. Summary by Directory 3.1 Weekly Assessment and Strategy Recommendation - **PX**: The price decreased last week. The supply side saw a decline in load in China and Asia, with some device maintenance. The demand side had a slight increase in PTA load. Inventory is expected to slightly decrease in October. PXN expanded passively, and it is recommended to observe in the short term [11]. - **PTA**: The price decreased last week. The supply side had a slight increase in load, and maintenance in October decreased slightly. The demand side had a slight decline in polyester load, and the terminal showed signs of weakness. Inventory is expected to slightly accumulate. The processing fee was under pressure, and short - term observation is recommended [12]. - **MEG**: The price decreased last week. The supply side had an increase in load, and maintenance devices were few. The demand side had a slight decline in polyester load. Inventory is expected to gradually accumulate in the medium - term, and it is recommended to short on rallies [13]. 3.2 Futures and Spot Market - **PX**: The basis and spread were weakly volatile. The position increased, and the trading volume was neutral [32][35]. - **PTA**: The basis was at a low level, and the spread weakened. The position and trading volume were at low levels [44][47]. - **MEG**: The basis was stable, and the spread weakened. The position and trading volume were at low levels [57][63]. 3.3 p - Xylene Fundamental - **Capacity**: There will be new capacity commissioning in 2025 [77]. - **Supply**: The import volume increased in August, and the inventory was stable in August. PXN expanded passively, and the naphtha spread declined [83][91][95]. - **Aromatic Blending Oil**: The gasoline performance weakened, the US - South Korea aromatic spread changed, and the blending oil relative value and South Korea's aromatic inventory also changed [102][111][113]. 3.4 PTA Fundamental - **Capacity**: There will be new capacity commissioning in 2024 - 2025 [135]. - **Supply**: The export volume decreased in August, and the inventory remained at a low level. The processing fee was weak [140][143][146]. 3.5 Ethylene Glycol Fundamental - **Capacity**: There will be new capacity commissioning in 2024 - 2025 [150]. - **Supply**: The start - up was high, and the load of syngas - based devices was at a historical high. The import volume was slightly flat in August, and the port inventory increased slightly this week [153][155][161]. - **Cost**: Coal prices declined, and ethylene prices fell [171]. 3.6 Polyester and Terminal - **Polyester**: New filament devices were commissioned. The basis of staple fiber strengthened, and the basis of bottle chips fluctuated. The start - up rate remained high, the inventory of filament was neutral, the profit of filament improved, and the export situation varied [187][191][194]. - **Terminal**: The start - up was still low. The orders and inventory of textile enterprises were stable, and the raw material inventory decreased. The domestic demand growth rate of textile and clothing recovered, but exports were weak. The US clothing inventory was below the pre - pandemic high, and the inventory increased marginally [214][221][225].

Report Summary 1. Report Industry Investment Rating No information provided in the report. 2. Core Viewpoints - This week, the overall atmosphere in the commodity market was strong, but the prices of finished steel products fluctuated downward. The demand for steel is currently weak, and although Trump's remarks caused short - term disturbances to commodity prices, the long - term trend of steel prices has not changed fundamentally in the context of a gradually loosening macro - environment. In the short term, the weak demand pattern is difficult to improve significantly. Attention should be paid to the intensity and direction of policies issued around the Fourth Plenary Session of the 20th Central Committee [9][10]. - The Fourth Plenary Session of the 20th Central Committee of the Communist Party of China is expected to make an overall plan for the economic development in the next five years, which is of great guiding significance for the macro - economic trend. Other factors such as the meeting's stance and the progress of Sino - US negotiations also need to be focused on [9][10]. 3. Summary by Relevant Catalogs 3.1 Cost End - The profit of hot - rolled blast furnaces was - 46 yuan/ton, and the gross profit of hot - rolled coils shrank rapidly. The spot price was about 136 yuan/ton higher than the futures price, with a neutral - to - low valuation [7]. 3.2 Supply End - This week, the output of hot - rolled coils was 3.22 million tons, a week - on - week decrease of 15,000 tons, a year - on - year increase of about 4.4% for the single week, and a cumulative year - on - year increase of about 1.7%. The daily average pig iron output was 2.4095 million tons, remaining above 2.4 million tons during the peak season. The profit of blast furnaces for producing rebar in East China remained around - 51 yuan/ton, and the immediate profit declined significantly. The loss of electric - arc furnace plants expanded, with the off - peak electricity profit at - 60 yuan/ton [8]. 3.3 Demand End - This week, the consumption of hot - rolled coils was 3.16 million tons, a week - on - week increase of 205,000 tons, a year - on - year decrease of about 0.1% for the single week, and a cumulative year - on - year increase of about 1.4%. The slow recovery of demand led to an insignificant inventory reduction effect. The growth rate of export demand decreased significantly, which may further drag down the demand for sheet metal [8]. 3.4 Inventory - This week, the inventory of hot - rolled coils was 4.1919 million tons, rising for five consecutive weeks and reaching the highest level in the past five years [9]. 3.5 Transaction Strategy - The recommended strategy is to wait and see, with no specific profit - loss ratio, recommended cycle, core driving logic, recommended grade, or first - proposed time provided [11].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The global soybean supply and demand pattern shows no obvious positive factors. The new - season soybean planting in Brazil is progressing normally, and the estimated planting area is increasing. The domestic soybean import cost is expected to fluctuate weakly. The domestic double - meal market is under real - time supply pressure, with soybean inventory at a record high and no clear positive factors on the cost side. In the medium term, the expectation of a loose global soybean supply remains unchanged, setting the direction of selling on rebounds. In the short term, there are uncertainties in South American planting and weather, and the bean - meal destocking season provides some support. It is expected that the bean - meal market will fluctuate weakly [9]. 3. Summary by Directory 3.1. Weekly Assessment and Strategy Recommendation - **International Soybeans**: This week, US soybeans fluctuated weakly. The global soybean supply - demand pattern shows no obvious positive factors. Brazil's new - season soybean planting is progressing normally, and institutional estimates suggest an increase in the planting area. Brazil's premium quotes fluctuated this week, and the soybean arrival cost remained stable. The valuation of US soybeans is currently slightly low, and there is some room for the Brazilian premium to decline. Since there is no significant decline in the global soybean supply, the domestic soybean import cost is expected to fluctuate weakly. Whether to import US soybeans is yet to be determined. If China continues not to import US soybeans, the Brazilian quotes will remain strong, providing some support for the bean - meal market. If partial or full import of US soybeans is allowed, the bean - meal market may first trade the short - term supply pressure, causing the price to decline. Then, after the game between US soybeans and the Brazilian premium ends, the import cost will stabilize, and the bean - meal market will trade based on the cost [9]. - **Domestic Double - Meal**: This week, the domestic bean - meal spot market weakened, the basis increased, the futures market weakened, and the oil - mill's futures crushing profit declined. Domestic trading volume was average, and the pick - up volume rebounded to a relatively high level. The inventory days of feed enterprises were 7.93 days, slightly higher than the same period last year, with a month - on - month decrease of 0.41 days. As of October 14, institutional statistics showed that the purchased volume in August was 9.2 million tons, 8.76 million tons in September, 8.26 million tons in October, and 5.33 million tons in November. The current purchase progress indicates that the domestic soybean inventory may decline around the end of September. Coupled with the large - scale pick - up of domestic bean - meal, the domestic bean - based basis has some support [9]. - **Trading Strategy**: The unilateral strategy is that the market is expected to fluctuate weakly. The core driving logic is that the domestic supply is under real - time pressure, with soybean inventory at a record high and no clear positive factors on the cost side. In the medium term, the expectation of a loose global soybean supply remains unchanged, setting the direction of selling on rebounds. In the short term, there are uncertainties in South American planting and weather, and the bean - meal destocking season provides some support [11]. 3.2. Futures and Spot Market - **Spot Price**: The report presents the historical spot price trends of soybean meal in Dongguan, Guangdong, and rapeseed meal in Huangpu, Guangdong, from 2021 to 2025 [17][18]. - **Basis of the Main Contract**: The report shows the historical basis trends of the soybean - meal 01 contract and the rapeseed - meal 01 contract from February to October 2025 [20][21]. - **Spread**: The report displays the historical spread trends of the soybean - meal 01 - 05, 03 - 05, 11 - 1 spreads, and the soybean - meal 01 - rapeseed - meal 01 spread from 2021 to 2026 [22][23]. - **Fund Position**: The report shows the historical net - long positions of the management funds in US soybeans and US soybean meal from May 2020 to September 2025, along with the corresponding futures prices [25][26][29]. 3.3. Supply Side - **US Soybean Planting Progress**: The report presents the historical planting progress, emergence rate, flowering rate, and excellent - good rate of US soybeans from 2021 to 2025 [31][32]. - **Weather Conditions**: There is a possibility of La Niña occurring from October 2025 to January 2026. The report also shows the weighted precipitation and forecasts in the US and Brazilian soybean - producing areas until October 31, 2025, as well as the impact and frequency of La Niña on precipitation in North America from July to September and its climate impact on South America [34][35][36]. - **US Soybean Export Progress**: The report shows the historical trends of the total export contracts signed by the US soybeans in the current market year to China, the sales completion rate of the current year, the total export contracts signed in the current market year, and the cumulative export shipment volume to China from 2021/22 to 2025/26 [49][50]. - **China's Oilseed Imports**: The report presents the historical monthly import volume and forecasts of soybeans and rapeseeds in China from 2021 to 2025 [52][53]. - **China's Oil - Mill Crushing Situation**: The report shows the historical soybean and rapeseed crushing volumes of major oil mills from 2021/22 to 2025/26 [54][55]. 3.4.

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - The fundamentals of the PVC industry are poor, with the supply-demand situation being supply - strong and demand - weak. The comprehensive profit of enterprises has declined to a low level for the year, but the supply - side maintenance volume is small, and the output is at a historical high. In the short term, multiple new devices will start trial operations. Domestically, downstream construction has declined, and domestic demand is weak. Regarding exports, the anti - dumping tax rate in India is expected to be implemented soon, and the export outlook for the fourth quarter is poor. Although the short - term valuation has declined to a low level, it still cannot support the supply - demand situation that is weaker than in the first half of the year. In the medium term, pay attention to short - selling opportunities on rallies [11]. 3. Summary by Directory 3.1 Week - to - Week Assessment and Strategy Recommendation - **Cost and Profit**: The price of Wuhai calcium carbide is 2,425 yuan/ton, up 25 yuan/ton week - on - week; the price of Shandong calcium carbide is 2,830 yuan/ton, down 60 yuan/ton week - on - week; the price of medium - grade semi - coke in Shaanxi is 730 yuan/ton, unchanged week - on - week. The comprehensive profit of chlor - alkali integration has slightly recovered, while the profit from ethylene - based production is at a low level, and the current valuation is moderately low [11]. - **Supply**: The PVC capacity utilization rate is 76.7%, a 5.9% decline from the previous week. Among them, the utilization rate of calcium carbide - based production is 74.7%, down 8.2% week - on - week, and that of ethylene - based production is 81.3%, down 0.6% week - on - week. Last week, the supply - side load decreased mainly due to maintenance at enterprises such as Xinfeng, Lutai Chemical, Inner Mongolia Junzheng, Jinyuyuan, Tianye, and Zhongtai. The load is expected to rebound next week. The overall load in October is still expected to be high, and multiple devices are expected to start trial operations, resulting in continuous high supply pressure [11]. - **Demand**: Regarding exports, the anti - dumping tax rate in India is expected to be implemented in October - November, and exports are expected to decline after implementation. The construction rates of the three major downstream sectors decreased last week. The load of the pipe sector is 32.8%, down 7.6% week - on - week; the load of the film sector is 68.9%, up 5% week - on - week; the load of the profile sector is 15.9%, down 23% week - on - week. The overall downstream load is 39.2%, down 8.6% week - on - week, indicating weak overall downstream construction. Last week, the pre - sales volume of PVC was 55.6 tons, a decrease of 2.8 tons from the previous week [11]. - **Inventory**: Last week, the in - factory inventory was 36 tons, a decrease of 2.3 tons from the previous week; the social inventory was 103.4 tons, a decrease of 0.3 tons from the previous week; the total inventory was 139.4 tons, a decrease of 2.6 tons from the previous week; the number of warehouse receipts remained at a high level. The industry is still in the inventory accumulation cycle, with upstream inventory gradually shifting to the mid - stream. Given the supply - strong and demand - weak situation, the inventory accumulation is expected to continue [11]. 3.2 Futures and Spot Market - Multiple graphs are presented, including those showing the PVC term structure, the price of East China SG - 5 PVC, the PVC spot basis, the 1 - 5 spread of PVC, the positions and trading volumes of active PVC contracts, and the total positions and trading volumes of PVC. These graphs are sourced from WIND, Steel Union, and the research center of Wukang Futures [15][16][25][27]. 3.3 Profit and Inventory - **Inventory**: The overall inventory decreased this week, and the number of warehouse receipts was at a high level. Graphs show the in - factory inventory of calcium carbide - based PVC, the social inventory of PVC, the combined in - factory and social inventory of PVC, and the number of PVC warehouse receipts [32][39]. - **Profit**: Graphs show the comprehensive profit of chlor - alkali integration with externally purchased calcium carbide in Shandong, the profit of calcium carbide - based PVC production, the profit of ethylene - based PVC production, and the profit of calcium carbide production in Inner Mongolia [40]. 3.4 Cost Side - **Calcium Carbide**: Calcium carbide prices have stabilized. Graphs show the prices of Wuhai and Shandong calcium carbide, calcium carbide inventory, and calcium carbide production start - up rate [46][47]. - **Semi - coke and Caustic Soda**: The prices of semi - coke and caustic soda have remained stable.

1. Report Industry Investment Rating No relevant content is provided in the report. 2. Core Viewpoints of the Report - Although the current real - world situation for manganese and silicon ferroalloys remains unfavorable, most of this has been factored into prices. Subsequent macro - level factors, such as important meetings, may be more crucial. The market's anticipation trading for future important meetings is currently insufficient, and attention should be paid to potential expectation gaps [15][97]. - For the future of the black sector, there is no pessimism. It is considered that seeking rebound opportunities after price corrections may be more cost - effective. After nearly four years of decline, the downward momentum of the black sector has significantly weakened [15][97]. - Manganese silicon's fundamentals are not ideal and lack a major driving force. Potential drivers may come from the manganese ore end. If the black sector strengthens, the manganese ore end may trigger a market for manganese silicon. Otherwise, it will likely follow the black sector's trend [15]. - The supply - demand fundamentals of silicon ferroalloy have no obvious contradictions or drivers and will probably follow the black sector's trend, with relatively low operational cost - effectiveness [97]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - This week, tin prices declined and adjusted. In terms of supply, the seasonal maintenance work of large - scale smelters in Yunnan was basically completed, and the smelter operating rate increased to some extent, but the overall operating level was still at a historical low. The core issue was the continuous shortage of tin ore raw material supply. Although the mining licenses in Wa State, Myanmar, had been approved, affected by the rainy season and the slow actual resumption of production, the tin ore export volume was still far below the normal level and could not effectively make up for the supply gap. In terms of demand, the long - term demand expectations brought by emerging fields such as new energy vehicles and AI servers provided support for tin prices, but currently, their scale was not sufficient to fully offset the weak consumption in traditional fields. The spot market trading was light, and downstream enterprises had limited acceptance of prices above 280,000 yuan/ton, mostly choosing to make small - quantity purchases for rigid needs, and the overall market trading atmosphere was not strong. In terms of inventory, the total social inventory of tin ingots in major regions across the country this week was 7,925 tons, an increase of 141 tons from last week. In summary, the short - term tin supply remained tight, and tin prices were expected to remain stable or rebound slightly [12][13]. 3. Summary According to Relevant Catalogs 3.1. Weekly Assessment and Strategy Recommendation - Cost side: Although the mining licenses in Wa State, Myanmar, had been approved recently, the resumption of production was slow, and it was expected that the tin ore supply would not be significantly restored until the fourth quarter. In August 2025, China's imported physical volume of tin concentrate reached 10,267 tons, the same as the previous month. The volume of imported tin concentrate from countries such as the Democratic Republic of the Congo, Russia, and Bolivia had declined, but the overall volume was at a normal level, only affected by shipping factors such as the shipping schedule. The volume of imported tin ore from Myanmar had increased, and with the approval of the mining license, there were signs of short - term supply improvement. The volume of imported tin ore from other regions and countries remained at the previous level [12]. - Supply side: The resumption of production of tin mines in Wa State, Myanmar, was slow and difficult to increase production before November. The shortage of raw materials for smelting enterprises in Yunnan still existed. Coupled with the maintenance of a large - scale smelting enterprise in September, the operating rate in Yunnan dropped significantly this week. In Jiangxi, due to a significant reduction in scrap and insufficient supply of crude tin, the refined tin output continued to be at a low level. According to third - party data, it was expected that the domestic refined tin output in September would decrease by 29.89% month - on - month [12]. - Demand side: The new energy vehicle and AI server sectors downstream continued to be booming, but the demand in the traditional consumer electronics and home appliance sectors, which accounted for the majority of demand, remained sluggish. According to the latest production scheduling report of three major white goods released by Industry Online, the total production scheduling volume of air conditioners, refrigerators, and washing machines in September 2025 was 27.07 million units, a 7.2% decrease compared with the actual production volume in the same period last year. In the short term, with the arrival of the traditional peak seasons of "Golden September and Silver October", downstream consumption improved marginally. In August, the operating rate of tin solder of domestic sample enterprises rebounded to 73.22%, showing a significant improvement compared with July [12]. 3.2. Futures and Spot Market No specific analysis content provided, only some charts are presented, including the basis of Shanghai tin main - continuous contract and the LME tin premium/discount (0 - 3) [19][20]. 3.3. Cost Side - The short - term supply of tin ore was generally tight, and the processing fees remained at a low level [27]. - Some charts are presented, including China's monthly tin ore production, tin ore import volume, tin concentrate price, and tin concentrate processing fee [24][26]. 3.4. Supply Side - Some charts are presented, including domestic refined tin monthly output, domestic recycled tin monthly output, tin output and operating rate in Yunnan and Jiangxi, refined tin export and import profits, domestic refined tin import volume, and Indonesia's refined tin import and export [31][33][36][39]. 3.5. Demand Side - China's semiconductor sales growth rate rebounded slightly, and global semiconductor sales maintained high growth [45]. - Some charts are presented, including domestic computer and smartphone production, production of household appliances such as washing machines, air conditioners, refrigerators, and color TVs, China's photovoltaic cell production and photovoltaic installation cumulative volume, domestic key enterprise tin - plated strip production, PVC monthly output, downstream solder enterprise operating rate, and domestic tin apparent consumption [44][47][49][51][53][55][58]. - Tin consumption in the tinplate field continued to decline because aluminum cans had almost completely replaced tinplate cans in the beverage packaging field. PVC stabilizers were the major consumer of tin compounds, and PVC production increased slightly year - on - year in the first half of the year [56]. 3.6. Supply - Demand Balance - Some charts are presented, including China's social inventory and LME inventory [62].
