Investment Rating - The report indicates a positive investment outlook for the global tin industry, driven by resource advantages and AI technology, leading to a tight supply-demand balance that is expected to push prices upward [2]. Core Insights - The global tin industry is experiencing a new growth cycle fueled by the dual drivers of AI technology and green transformation. The demand for tin, a strategic metal, is surging in high-end manufacturing sectors such as AI chips, electric vehicles, and 5G communications, while traditional applications like solder and tin-plated boards continue to grow steadily. On the supply side, limited growth in global tin concentrate supply is due to declining ore grades, stricter environmental policies, and geopolitical factors, resulting in a sustained upward shift in tin prices [2][4][5]. Summary by Sections Industry Overview - Tin is a scarce metal with a melting point of 231.89°C, widely used in electronic soldering, food packaging, and chemical catalysis. Its abundance in the earth's crust is only 0.004%, primarily found in granite, volcanic rocks, and sedimentary metamorphic deposits [3][8]. Supply and Demand Dynamics - The global tin supply has been declining, with reserves dropping from 9.6 million tons in 2000 to 4.3 million tons in 2024. The supply is highly concentrated in a few countries, including China, Myanmar, and Australia, which face challenges such as low ore grades and declining mining yields [4][18][20]. Price Trends - The report highlights that the tin market is sensitive to supply disruptions, which can lead to significant price volatility. Historical data shows that supply disturbances have caused sharp price fluctuations, particularly during periods of reduced production in major producing countries [36][38]. Future Outlook - The report anticipates a growing supply-demand gap in the coming years, driven by the explosive growth in AI PC and server markets, which significantly increases the demand for tin. The shift towards diversified import sources for China, moving away from heavy reliance on Myanmar, is also noted as a strategic response to supply chain vulnerabilities [47][42].

Group 1: Supply Dynamics - The slow recovery of tin production in Myanmar's Wa State and Indonesia's crackdown on illegal tin mining are exacerbating the supply tightness of tin ore [1][2] - China's tin concentrate imports have been declining, with September 2025 imports at 8,714 tons, down 29.8% month-on-month and 17.7% year-on-year [2] - Indonesia's tin production is projected to be around 50,000 tons in 2024, accounting for approximately 16.7% of global tin concentrate production, which will further impact global supply [2] Group 2: Processing Fees and Market Conditions - The processing fees for tin concentrate in Yunnan and Jiangxi are at 12,000 yuan/ton and 8,000 yuan/ton respectively, reflecting the tight domestic supply and supporting tin prices [2] - The current processing fees are at their lowest level in nearly three years, indicating a tight supply situation [2] Group 3: Refined Tin Production - The total refined tin production from 18 domestic smelting plants was 14,044 tons in September 2025, down 18.1% month-on-month but up 16.6% year-on-year [3] - In the first nine months of 2025, these sample enterprises produced a total of 153,000 tons of refined tin, a year-on-year increase of 6.9% [3] Group 4: Consumption Trends - The chemical sector accounts for about 20% of total refined tin consumption, with PVC production being a significant driver, although the real estate market's performance has been weak [4] - The soldering materials sector represents about 40% of refined tin consumption, with demand expected to rise due to the recovery of the semiconductor industry and strong performance in the automotive market [4] - In the first nine months of 2025, China's automobile production and sales reached 24.05 million and 24.36 million units, respectively, with year-on-year growth of 10.9% and 12.9% [4] Group 5: Price Outlook - Given the favorable factors in the market, tin prices are expected to break through the 285,000 yuan/ton level in the short term [5]

Group 1 - The core viewpoint indicates that the tin price trend in the second half of 2025 is dominated by global supply tightness, with significant influences from Myanmar's slow recovery and Indonesia's crackdown on illegal mining, alongside macroeconomic factors supporting price increases [1][4] - The recovery of tin production in Myanmar is expected to be the main driver for marginal supply improvement in Q4 2025, with imports from Myanmar anticipated to steadily increase, alleviating raw material inventory issues in Yunnan smelting plants [2][4] - Domestic refined tin production faced constraints due to raw material shortages, with September production dropping significantly by 34.69% to 9,770 tons, but is expected to rebound as raw material supply improves and smelting capacities are gradually released [2][3] Group 2 - The traditional consumption sectors for tin, particularly the electronics market, continue to show weak performance, with a reported 6.0% year-on-year decline in domestic mobile phone shipments in August 2025 [3] - The photovoltaic sector is also under pressure, with a 1.8% year-on-year decline in newly installed solar capacity in Q3 2025, indicating overall demand weakness [3] - The overall demand for tin is expected to remain weak, limiting the price support from the demand side, despite some growth in tin consumption from AI servers [3][4] Group 3 - The tin market in Q4 is characterized by "marginal supply improvement and continued demand weakness," with supply growth from Myanmar and Indonesia putting pressure on tin prices, while low global tin inventories and macroeconomic factors provide limited downside [4] - The Shanghai tin main contract is projected to fluctuate within the range of 270,000 to 300,000 yuan per ton, with close attention needed on the actual supply increase from Myanmar and changes in domestic and international macro policies [4]

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].

Report Summary 1) Report Industry Investment Rating - The report suggests a bullish outlook for the tin market in the medium term, advising investors to adopt a long - position strategy [4]. 2) Core Viewpoints - The disruption in the Indonesian tin supply and the slow recovery of overseas tin mines, combined with macro - economic factors, have led to a shortage in the global tin supply, causing tin prices to soar. The supply is expected to remain tight before mid - October, and the tin price may continue to strengthen. The复产 speed of the Burmese tin mines may determine the supply elasticity of tin, and if the Indonesian crackdown exceeds expectations or the Burmese复产 is further delayed, the tin price may break through the previous high [2][4]. 3) Summary by Related Aspects Indonesian Supply - Indonesia, the world's largest tin exporter (accounting for over 25% of global supply), has intensified the global tin supply shortage. The Indonesian president ordered the closure of 1000 illegal tin mines on September 29 and plans to crack down on 80% of illegal mining activities. The illegal mine closure may widen the global tin mine supply gap to over 8000 tons in the fourth quarter. In August, Indonesia's tin ingot exports were 3246.46 tons, a 14.39% month - on - month decrease, and exports are expected to continue to decline significantly [2]. Burmese Supply - The复产 of Burmese tin mines is progressing slowly. In August, China imported only 2091 tons of tin ore from Burma, a 27.72% year - on - year decrease, accounting for only 20% of the total domestic imports. Due to the rainy season, equipment shortages, and explosive controls, the actual output remains low, and the output increase is expected to be realized in November [4]. Domestic Supply - Overseas tin mine supply recovery is slow, and domestic raw material supply is tight. Domestic smelter operating rates are continuously decreasing. Yunnan tin smelters have been on a 45 - day maintenance since August 30, and Jiangxi's refined tin output remains low due to a shortage of scrap and crude tin. Domestic smelter output is expected to recover around mid - October, and the low LME tin inventory cannot be quickly replenished [4]. Macroeconomic Factors - The probability of the Fed cutting interest rates in October is 93%. The weakening US dollar and the expectation of loose liquidity have boosted the overall sentiment of the non - ferrous metals sector [4].

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].

Group 1 - The core viewpoint indicates that tin prices are experiencing narrow fluctuations, with the main contract rising by 0.46% to 268,090 yuan per ton, amid slow recovery of tin mines in Myanmar and weak supply-demand fundamentals [1] - The recovery of tin mines in Myanmar is progressing slowly due to seasonal rains, earthquakes, and preparation issues, leading to a delay in actual output expected until the fourth quarter [1] - The operating rate of tin smelting enterprises remains low due to tight raw material supply, with the operating rate in Yunnan and Jiangxi provinces reaching 59.23% as of August 15, showing a slight month-on-month decline [1] Group 2 - Downstream orders for tin continue to decline, with the third quarter being a traditional off-season for consumption, resulting in lower orders in the home appliance sector compared to previous years [2] - The semiconductor market is expected to grow, driven by demand from AI, cloud infrastructure, and advanced consumer electronics, although some sub-segments may continue to shrink [2] - The overall demand for tin in photovoltaic solder remains weak due to a significant drop in orders following a mid-year rush for installations [2]

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - This week, tin prices fluctuated and declined. In terms of supply, the mining licenses in the Wa region of Myanmar have been approved, and preparations are underway, with significant recovery in tin ore supply expected in Q4. However, in the short term, raw material shortages in Yunnan are still severe, and some smelters are preparing for maintenance. In Jiangxi, some recycled tin enterprises have resumed production, but the subsequent output is difficult to increase due to the limited supply of scrap tin. In terms of demand, domestic consumption during the off - season remains poor, and downstream factories are cautious about restocking tin raw materials. Overseas, the demand for tin driven by AI computing power remains strong. In terms of inventory, the social inventory of tin ingots increased slightly this week. Overall, the short - term supply and demand are both weak, and due to the continuous resumption of production in Myanmar, it is expected that tin prices will fluctuate weakly in the short term. The short - term operating range of domestic tin prices is expected to be between 250,000 - 270,000 yuan/ton, and the operating range of LME tin prices is expected to be between 31,000 - 33,000 US dollars/ton [11][12]. 3. Summary According to the Directory 3.1 Week - on - Week Assessment and Strategy Recommendation - **Supply Side**: The mining licenses in the Wa region of Myanmar have been approved, and preparations are underway, with significant recovery in tin ore supply expected in Q4. In Yunnan, raw material shortages are severe, and smelter raw material inventories are generally less than 30 days, with some enterprises preparing for maintenance. In Jiangxi, some recycled tin enterprises have ended maintenance and gradually resumed production, but the supply of scrap tin is limited, and subsequent output growth is difficult [11]. - **Import and Export**: The resumption of tin ore production in Myanmar is slow, and the supply from other regions is limited. China's tin ore imports remain at a low level. In June 2025, China's tin concentrate imports were 11,910 tons, a month - on - month decrease of 11.44% and a year - on - year decrease of 7.08%. From January to June, the total import volume of tin concentrates was 62,130 tons, a year - on - year decrease of 32.41% [11]. - **Demand Side**: Consumption during the off - season is poor, and downstream factory orders are generally low. After the end of the photovoltaic rush to install, orders for photovoltaic tin bars in East China have declined, and the operating rate of some producers has decreased. The production schedules of home appliance enterprises in July also decreased significantly. In July 2025, the total production schedule of air conditioners, refrigerators, and washing machines was 29.6 million units, a 2.6% decrease compared to the actual production in the same period last year. Orders for consumer electronics and automotive electronics have weak growth, and market sentiment is cautious. The demand for tin in tin - plated sheets and the chemical industry is relatively stable [11]. - **Summary**: Tin supply is at a low level, and demand is also weak. In the short term, supply and demand are both weak, and due to the continuous resumption of production in Myanmar, it is expected that tin prices will fluctuate weakly in the short term. The short - term operating range of domestic tin prices is expected to be between 250,000 - 270,000 yuan/ton, and the operating range of LME tin prices is expected to be between 31,000 - 33,000 US dollars/ton [11][12]. 3.2 Futures and Spot Market - The report provides charts of the basis of Shanghai tin main contract and the LME tin premium (0 - 3), but no specific analysis content is given [18][20]. 3.3 Profit and Inventory - **Profit**: The report provides charts of tin import and export profits, but no specific analysis content is given [24][25]. - **Inventory**: The social inventory of tin ingots in China and the LME inventory charts are provided. As of August 1, 2025, the social inventory of tin ingots in major Chinese markets was 10,661 tons, an increase of 272 tons compared to last Friday [11][27]. 3.4 Cost Side - Tin ore supply is generally tight, and processing fees remain at a low level [33]. 3.5 Supply Side - **Domestic Production**: In May, affected by raw material shortages and low processing fees, the refined tin production was 14,670 tons, a month - on - month decrease of 0.3% and a year - on - year decrease of 8.3% [38]. - **Import and Export**: In May, the import of tin ore and concentrates was 13,448.797 physical tons, a year - on - year increase of 59.83% and a month - on - month increase of 36.38%. From January to May, the cumulative import was 50,200 physical tons, a cumulative year - on - year decrease of 36.51%. The export of unforged non - alloy tin was 1,770 tons, a year - on - year increase of 18.01% and a month - on - month increase of 8.12%. From January to May, the cumulative export was 9,584 tons, a cumulative year - on - year increase of 38.48%. The import of unforged non - alloy tin was 2,076 tons, a year - on - year increase of 226.14% and a month - on - month increase of 84.07%. From January to May, the cumulative import was 9,508 tons, a cumulative year - on - year increase of 30.91% [38][41]. 3.6 Demand Side - **2024 Consumption Structure**: In 2024, consumption showed a steady growth trend, with the increase mainly coming from the recovery of semiconductor consumption and the increase in photovoltaic module production. In China, solder consumption is still dominant, and the increase mainly comes from the production of photovoltaic modules and the recovery of semiconductor consumption. Overseas, the recovery of semiconductor consumption also drove the growth of tin consumption, but overall growth was slower than in China [51]. - **Semiconductor**: The year - on - year growth rate of China's semiconductor sales has slightly rebounded, and global semiconductor sales have maintained high growth [56]. - **Photovoltaic**: In the first four months of 2025, there was a phased rush to install photovoltaic in China, with significant production growth. In June, the component production schedule decreased significantly month - on - month [62]. - **Home Appliances**: According to the latest production schedule report of three major white goods, in July 2025, the total production schedule of air conditioners, refrigerators, and washing machines was 29.6 million units, a 2.6% decrease compared to the actual production in the same period last year [70].

Group 1 - LME inventory has decreased significantly from approximately 4,800 tons at the beginning of the year to 1,690 tons, representing a cumulative reduction of 65%, reaching a near two-year low [1] - The low inventory levels have increased the risk of short selling in LME tin, with a major holder owning 50-79% of the warehouse receipts, and concentrated long positions in the near term [1] - The LME 0-3 spot premium has expanded significantly, leading to a substantial increase in night trading for LME tin, which in turn has driven up domestic tin prices [1] Group 2 - China's tin ingot imports saw a slight decline in June, while exports increased, with the overall import level expected to decrease due to a persistently closed import window and low profit margins [2] - The domestic supply of refined tin is under pressure, with expectations of substantial outflows of tin ore in Q4 due to the reopening of mining operations in Myanmar [2] - The consumption side is facing challenges, particularly in the photovoltaic sector, which is suppressing solder demand, and the electronics and automotive electronics sectors are entering a seasonal downturn, leading to weak order growth [2]
