1. Report Industry Investment Rating No relevant information provided. 2. Core View of the Report The slow resumption of tin mines in Wa State, Myanmar, has led to an expectation of tight supply and demand. However, due to the hawkish shift in the Fed's interest - rate cut expectations, the strengthening of the US dollar index, and tight liquidity, the Shanghai tin price may be adjusted. It is recommended that investors try short - selling the main contract at high levels with a light position in the short term, and pay attention to the support and resistance levels of Shanghai tin and London tin [3]. 3. Summary by Relevant Catalogs 3.1 First Part: Spread and Inventory Situation - The Shanghai tin basis is positive and the monthly spread is negative, both within the reasonable range. This is due to the slow resumption of tin mines in Wa State, Myanmar, leading to an expected tight supply, and a decline in the total inventory of refined tin at home and abroad. However, with the hawkish shift in the Fed's future interest - rate cut expectations, the strengthening of the US dollar index, tight liquidity, and the arrival of the domestic traditional consumption off - season, investors are advised to temporarily wait and see for arbitrage opportunities [7][9]. - The LME tin (0 - 3) and (3 - 15) contract spreads are positive and within the reasonable range. The Shanghai - London tin price ratio is lower than the 50% quantile of the past five years. This is because the manufacturing PMI in Europe and the US in October was weak, and the inventory of refined tin in the LME is increasing but still at a relatively low level. It is recommended to temporarily wait and see for arbitrage opportunities in the LME tin (0 - 3) and (3 - 15) contract spreads [11]. - The inventory of refined tin in the Shanghai Futures Exchange has increased compared to last week; the social inventory of tin ingots in China has decreased compared to last week; the inventory of refined tin in the LME has increased compared to last week; the total inventory of refined tin at home and abroad has decreased compared to last week [13]. 3.2 Second Part: Mid - upstream Supply Situation - The daily processing fee of domestic tin ore has decreased, indicating an expected tight supply of domestic tin ore [19][20]. - The production (import) volume of domestic tin ore in November may increase month - on - month. Reasons include the closure of 1000 illegal tin mines in Bangka Belitung by the Indonesian president, the commissioning of the second concentrator of the Uis mine in Namibia, the resumption of mining in Wa State, Myanmar, the phased resumption of the Bisie tin mine in the DRC, and the suspension of the transit export of Myanmar tin ore through Thailand [22][24]. - The production volume of recycled tin in China in November may increase month - on - month [25][26]. - The capacity utilization rate of refined tin in Yunnan and China (Jiangxi) has decreased (remained flat) compared to last week; the production (inventory) volume of refined tin in China in November may increase (decrease) month - on - month [29]. - The import volume of refined tin in China in November may increase month - on - month. The export volume of refined tin from Indonesia is expected to increase, which may lead to an increase in China's refined tin imports [30][32]. 3.3 Third Part: Downstream Demand Situation - The daily processing fee of photovoltaic solder strips has decreased month - on - month, which may lead to an increase in the capacity utilization rate (inventory) of tin solder in China in November [36]. - The import (export) volume of solder strips in China in November may decrease (increase) month - on - month [37][39]. - The production (import, export) volume of tin - plated sheets in China in November may decrease (decrease, increase) month - on - month [40]. - The capacity utilization rate of lead - acid batteries in China has decreased compared to last week. Since tin is an important additive in lead - acid batteries, this may affect the demand for tin [42][44].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The slow resumption of tin mines in Myanmar and the easing of Sino-US economic and trade negotiations support tin prices. The expectation of future interest rate cuts and the halt of balance - sheet reduction by the Fed, along with the initial agreement in Sino - US economic and trade negotiations, suggest that the resumption of tin mines in Myanmar may not change the tight supply - demand situation. The Shanghai tin price is expected to be cautiously bullish. Investors are advised to build long positions after price pullbacks, paying attention to support and resistance levels [3]. - The negative basis and monthly spread of Shanghai tin are due to high tin prices suppressing downstream demand with only rigid procurement. Given the Fed's future policies and the slow resumption of tin mines in Myanmar, investors are advised to focus on short - term, light - position, low - buying arbitrage opportunities for the Shanghai tin basis. For LME tin, the positive (0 - 3) and (3 - 15) contract spreads are in a reasonable range, and it is recommended to temporarily wait and see for arbitrage opportunities [9][10]. 3. Summary by Directory 3.1 First Part: Spread and Inventory Situation - Shanghai tin basis is negative and at a relatively low level, and the monthly spread is negative and basically within a reasonable range. LME tin (0 - 3) and (3 - 15) contract spreads are positive and in a reasonable range, and the Shanghai - London tin price ratio is at the 50% quantile of the past five years [9][10]. - The inventory of refined tin on the Shanghai Futures Exchange decreased compared to last week; the social inventory of tin ingots in China decreased compared to last week; the inventory of refined tin on the London Metal Exchange increased compared to last week; the total inventory of refined tin at home and abroad decreased compared to last week [12]. 3.2 Second Part: Mid - upstream Supply Situation - The daily processing fee of domestic tin concentrates is oscillating downward, indicating a tight supply expectation of domestic tin mines.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - In September 2025, the domestic tin price showed a generally oscillating and strengthening trend, and it increased significantly at the beginning of October due to Indonesia's crackdown on illegal tin mines. - In the short - term, the shortage of tin supply is obvious, and the tin price is expected to remain stable at a high level. Attention should be paid to the resumption of production progress in Myanmar at the end of October [11][13]. 3. Summary by Relevant Catalogs 3.1 Monthly Assessment and Strategy Recommendation - Cost side: Although the mining permits in the Wa State of Myanmar have been approved, the resumption of production is slow. It is expected that the supply of tin ore will significantly recover in the fourth quarter. In August 2025, China's imported tin concentrate physical volume was 10,267 tons, unchanged from the previous month. Imports from countries such as the Democratic Republic of the Congo, Russia, and Bolivia decreased slightly due to shipping factors, while imports from Myanmar increased. Imports from other regions remained at previous levels [11]. - Supply side: The resumption of tin mines in the Wa State of Myanmar is slow and difficult to increase production before November. Raw material shortages in Yunnan's smelting enterprises still persist. In addition, a large - scale smelting enterprise in Yunnan started maintenance in September, leading to a significant decline in the operating rate in Yunnan this week. In Jiangxi, due to a significant reduction in scrap and insufficient supply of crude tin, the refined tin output remained at a low level. It is estimated that the domestic refined tin output in September will decrease by 29.89% month - on - month [11]. - Demand side: The new energy vehicle and AI server sectors continue to be booming, but the demand in traditional consumer electronics and home appliances, which account for the majority of demand, remains sluggish. The total production volume of air conditioners, refrigerators, and washing machines in September 2025 was 27.07 million units, a 7.2% decrease compared to the same period last year. In the short - term, with the arrival of the "Golden September and Silver October" peak season, downstream consumption has marginally improved, and the operating rate of domestic sample tin solder enterprises rebounded to 73.22% in August [11]. 3.2 Futures and Spot Market No specific text summary content provided, only relevant graphs about the basis of Shanghai tin main contract and LME tin premium (0 - 3) are presented [19]. 3.3 Cost Side - The short - term supply of tin ore is generally tight, and the processing fees remain at a low level [27]. 3.4 Supply Side - The resumption of tin mines in the Wa State of Myanmar is slow, and it is difficult to increase production before November. Yunnan's smelting enterprises face raw material shortages, and a large - scale smelting enterprise's maintenance in September led to a significant decline in the operating rate in Yunnan. In Jiangxi, due to a reduction in scrap, the supply of crude tin is insufficient, and the refined tin output remains low. It is estimated that the domestic refined tin output in September will decrease by 29.89% month - on - month [11]. 3.5 Demand Side - The new energy vehicle and AI server sectors continue to be booming, but the demand in traditional consumer electronics and home appliances remains sluggish. The total production volume of air conditioners, refrigerators, and washing machines in September 2025 decreased by 7.2% compared to the same period last year. - The year - on - year growth rate of China's semiconductor sales has slightly rebounded, and global semiconductor sales maintain high growth. - Tin consumption in the tinplate field continues to decline, mainly because aluminum cans have almost completely replaced tinplate cans in the beverage packaging field. The PVC output increased slightly year - on - year in the first half of the year [11][46][57]. 3.6 Supply - Demand Balance - Inventory: The social inventory of tin ingots continued to decline. Last Friday, the social inventory of tin ingots in major domestic markets was 8,352 tons, a decrease of 686 tons compared to September 19 [11][13].

Core Viewpoint - The tin market is experiencing fluctuations with a slight upward trend, driven by improved trading in the spot market and a notable reduction in social inventory, despite weak supply and demand fundamentals [1][2]. Group 1: Market Performance - The main tin contract rose by 1.5%, closing at 272,510 yuan/ton [1]. - Last week, tin prices experienced a continuous decline, but the spot market showed slight improvement due to downstream replenishment activities [1]. - The overall order levels in September remained stable compared to August, despite being in a peak consumption season [2]. Group 2: Supply and Demand Dynamics - The supply of tin is constrained by slow recovery in Myanmar's tin mines and low operating rates at domestic smelting enterprises due to high costs and seasonal production cuts [1]. - Myanmar's Wa State tin mine exports were around 1,200 tons in August, indicating a persistent supply gap [1]. - The overall consumption level in September is expected to decline compared to previous years, with most enterprises maintaining a wait-and-see approach [2]. Group 3: Industry Outlook - The electronic industry may see increased usage of tin solder due to trends in AI and humanoid robots, although overall demand remains limited [2]. - The recent price corrections have led to improved inventory levels in downstream warehouses, suggesting a potential for gradual recovery in production and operating rates for tin solder enterprises [2]. - Despite a slight recovery in the automotive market, other sectors remain weak, but domestic inventory has significantly decreased, providing strong support for tin prices [2].

1. Report Industry Investment Rating No information provided. 2. Core Viewpoints - Domestic and international macro - optimistic expectations and partial refining tin capacity maintenance support tin prices. The slow resumption of tin mines in Wa State, Myanmar, and the decline in domestic tin ingot social inventory may cause the Shanghai tin price to fluctuate strongly. It is recommended that investors mainly lay out long positions on dips, paying attention to specific support and pressure levels [3][4]. - For spreads and inventory, due to factors such as the weakening employment supply - demand in the US and the slow resumption of tin mines in Wa State, Myanmar, the basis and monthly spreads of Shanghai tin, as well as the spreads of LME tin contracts, are within a reasonable range, and investors are advised to temporarily wait and see for arbitrage opportunities. The total inventory of refined tin at home and abroad has increased compared with last week [10][11][15]. - In terms of supply, the domestic tin ore supply is expected to be tight, the production of recycled tin in September may decrease month - on - month, the production capacity utilization rate of refined tin has declined, and the import volume of refined tin may decrease month - on - month [21][25][30]. - In terms of demand, the production capacity utilization rate of tin solder may increase month - on - month, the import volume of solder strips may decrease month - on - month while the export volume may increase, and the production, import, and export volumes of tin - plated sheets may all decrease month - on - month. The capacity utilization rate of lead - acid batteries has slightly decreased [36][37][42]. 3. Summary by Directory 3.1 First Part: Spread and Inventory Situation - The basis and monthly spreads of Shanghai tin are negative and within a reasonable range. The (0 - 3) contract spread of LME tin is negative and the (3 - 15) contract spread is positive, both within a reasonable range. The Shanghai - London tin price ratio is between the 50 - 75% quantiles of the past five years. Investors are advised to temporarily wait and see for arbitrage opportunities [10][11]. - The inventory of refined tin in the Shanghai Futures Exchange has decreased compared with last week, the social inventory of tin ingots in China has increased, the inventory of refined tin in the London Metal Exchange has increased, and the total inventory of refined tin at home and abroad has increased [15]. 3.2 Second Part: Mid - upstream Supply Situation - The daily processing fee of domestic tin concentrate is oscillating downward, indicating a tight supply expectation of domestic tin ore [21]. - The second beneficiation plant of the Uis mine in Namibia has been commissioned, and tin mines in Wa State, Myanmar, are resuming production. Alphamin Resources' tin mine in Congo is also resuming production in stages. These factors may lead to an increase in domestic tin ore production and a decrease in imports in September [23]. - The production of recycled tin in China in September may decrease month - on - month [25]. - The production capacity utilization rate of refined tin in Yunnan and China (Jiangxi) has decreased (remained flat). Yunnan Tin will conduct maintenance on smelting equipment, resulting in a decrease in the production of refined tin in China in September and an increase in inventory [29]. - The export volume of Indonesia in September may decrease, which may lead to an increase in the import volume and a decrease in the export volume of refined tin in China in September [32]. 3.3 Third Part: Downstream Demand Situation - The daily processing fee of photovoltaic solder strips has decreased, which may lead to an increase in the production capacity utilization rate and a decrease in the inventory of tin solder in China in September [36]. - The import volume of solder strips in China in September may decrease month - on - month, while the export volume may increase [37]. - The production, import, and export volumes of tin - plated sheets in China in September may all decrease month - on - month [42]. - The production capacity utilization rate of lead - acid batteries in China has slightly decreased compared with last week [45].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - In August, domestic tin prices fluctuated strongly. The main reasons were the positive macro - atmosphere and the slow resumption of tin mines in Myanmar, which led to high ore prices and pushed up the center of tin prices. - On the supply side, the resumption of tin mines in Wa State, Myanmar was slow. The shortage of tin mines in Yunnan was still severe, with smelters' raw material inventory generally less than 30 days and low operating rates. Some smelting enterprises planned to conduct maintenance in September, further suppressing production. In Jiangxi, smelting enterprises maintained normal production, but the shortage of crude tin supply made it difficult to increase refined tin production. It is estimated that the refined tin production in September will decrease by 29.89% month - on - month. - On the demand side, it was the off - season for downstream consumption. Traditional consumption areas were weak. Although AI computing power increased some tin demand, the scale was still low, having limited impact on overall demand. The spot trading of tin was light due to weak terminal demand. - Overall, although the off - season consumption on the demand side was a bit weak, the short - term decline in supply was obvious. It is expected that tin prices will fluctuate mainly. [12][13] 3. Summary by Relevant Catalogs 3.1 Monthly Assessment and Strategy Recommendation - Cost end: Although the mining licenses in Wa State, Myanmar have been approved, the resumption progress is slow. It is expected that the tin ore supply will not significantly recover until the fourth quarter. In July, the domestic tin ore import volume was 10,200 tons (equivalent to about 4,335 metal tons), a month - on - month decrease of 13.71% and a year - on - year decrease of 31.79%, 688 metal tons less than in June. - Supply end: The slow resumption of tin mines in Myanmar and the shortage of tin mines in Yunnan led to low smelter operating rates. It is estimated that the refined tin production in September will decrease by 29.89% month - on - month. - Demand end: The consumption of electronic products such as smartphones and tablets was sluggish. The growth of emerging industries such as servers and AI glasses was fast but the scale was low, having limited impact on tin solder demand. After the end of the photovoltaic rush - installation, the component production decreased, leading to a significant decline in the demand for photovoltaic solder strips. The demand for tin in areas such as tin - plated sheets and chemicals was relatively stable. Downstream enterprises generally had low inventory levels and mainly purchased on - demand at low prices. [12] 3.2 Futures and Spot Market No specific analysis content is provided, only figures about the basis of Shanghai tin main contract and LME tin premium/discount are presented. [19] 3.3 Cost End - The short - term supply of tin ore is generally tight, and the processing fees remain at a low level. [27] 3.4 Supply End - The resumption of tin mines in Wa State, Myanmar is slow. Yunnan has a severe shortage of tin mines, and smelters' raw material inventory is generally less than 30 days. Some smelting enterprises in Yunnan plan to conduct maintenance in September, and the refined tin production in Jiangxi is difficult to increase due to the shortage of crude tin supply. It is estimated that the refined tin production in September will decrease by 29.89% month - on - month. [12] 3.5 Demand End - Semiconductor: China's semiconductor sales growth rate rebounded slightly, and global semiconductor sales maintained high growth. - Electronics: In the second quarter of 2025, the global PC shipments increased by 8.4% year - on - year. Mobile phone consumption continued to be sluggish, and it is predicted that the global smartphone shipments in 2025 will increase by 0.6% year - on - year to 1.24 billion units. The "trade - in" subsidy policy in the first half of the year stimulated the growth of consumer electronics to some extent, but the demand recovery was limited. - Automobile: In the first half of 2025, the new energy vehicle production increased by 40% year - on - year. - Home appliances: No overall summary is provided, but data on the production of various home appliances such as washing machines, air conditioners, refrigerators, and color TVs are presented. - Photovoltaic: There was a phased rush - installation in the first five months, with the installation volume growing by nearly 100% year - on - year. After the end of the rush - installation in June, the installation volume declined significantly. - Other: Tin consumption in the tin - plate field continued to decline, while the PVC output increased slightly year - on - year in the first half of the year. [46][49][55] 3.6 Supply - Demand Balance A supply - demand balance table from January 2023 to June 2025 is provided, including data on refined tin production, export, import, social inventory, social inventory change, and apparent consumption.
