Group 1 - The core viewpoint indicates that the tin market is expected to experience a phase of marginal supply easing and seasonal demand pressure in 2026, with global inventories remaining low and macroeconomic conditions providing support, leading to a high-level oscillation of the Shanghai tin futures contract [1][3] - The price of the Shanghai tin futures contract reached a three-and-a-half-year high of 323,700 yuan/ton due to supply concerns from geopolitical conflicts in the Democratic Republic of the Congo (DRC) and expectations of macroeconomic easing [1] - The resumption of production in Myanmar's Wa region is progressing, with the current mine recovery rate reaching two-thirds, and imports of tin from Myanmar are expected to rise significantly in early 2026 [1][2] Group 2 - Domestic refined tin smelting is expected to maintain stable operations in early 2026, with raw material constraints easing compared to 2025, benefiting from increased imports of tin from Myanmar [2] - The demand for tin in traditional sectors is showing signs of weakness, with the consumer electronics market not experiencing a substantial recovery, and global smartphone shipments predicted to decline by 0.9% year-on-year in 2026 [2][3] - The photovoltaic sector continues to face demand pressure, with a decrease in component production in early 2026, leading to weak demand for soldering materials [3]

Group 1: Market Data - The total trading volume of 12 Shanghai tin futures contracts is 264,157 lots, and the total open interest of Shanghai tin contracts is 103,486 lots. The open interest of Shanghai tin contract 2601 is 53,055 lots [5][6] Group 2: Spot Market - The closing price of today's Shanghai tin 2601 contract is 312,370 yuan/ton, the average spot price of Yangtze River spot 1 tin ingots is 309,500 yuan/ton, and the basis is -2,870 yuan/ton [7] Group 3: Influencing Factors 3.1 Industry News - On the supply side, the global tin ore supply constraint continues to strengthen. Geopolitical conflicts in the Democratic Republic of the Congo intensify transportation risks. The resumption of production in Myanmar is slower than expected, leading to a year-on-year sharp decline of 61.61% in imports. Indonesia's export policy shrinks the global supply. Although domestic smelters operate stably, the low processing fees for tin ore and raw material shortages restrict production capacity release, driving up the price support sentiment in the spot market [8] - On the demand side, the demand in traditional fields such as consumer electronics is weak. The operating rate of solder enterprises has declined, and they are cautious about taking delivery, which restricts the increase in spot prices. The demand in emerging fields such as AI servers and new energy vehicles is growing, supporting long-term expectations [8] - In terms of inventory, although the domestic visible inventory has slightly rebounded, it remains at a historically low level overall. Overseas inventory continues to be tight [8] Group 4: Market Outlook - In the short term, supported by both tight supply and macro - positive factors, the price of Shanghai tin will maintain a volatile and upward - trending pattern [11]

Core Viewpoint - The recent surge in tin prices is primarily driven by supply disruptions, particularly due to geopolitical tensions in the Democratic Republic of the Congo (DRC) and production challenges in Myanmar, while downstream demand shows mixed performance [1][2][3]. Supply Situation - Tin prices have accelerated since mid-October, with significant contributions from supply concerns related to the DRC's Alphamin mine, which has a production capacity of 17,000 tons [2]. - The DRC accounted for 20% of China's tin ore imports from January to October 2025, raising market fears about supply stability [1]. - The mining situation in Myanmar's Wa region has been hampered by a mining ban and operational challenges, leading to slower-than-expected production recovery [2]. - Overall, domestic smelting operations have returned to high levels post-maintenance, ensuring sufficient tin ingot supply [1]. Downstream Demand - Demand for tin is currently mixed, with strong growth in AI semiconductors and a 20% increase in electric vehicles contributing positively, while demand from the photovoltaic sector and home appliances has weakened significantly [3]. - Cumulative demand from January to October has decreased by 1.38% year-on-year, with expectations of further declines in November and December [3]. - The demand for refined tin solder, which constitutes about 50% of downstream usage, has seen a recovery in operating rates, currently around 75% [3]. Price Outlook - Short-term price increases may be limited due to demand pressures and unconfirmed supply disruptions, with current volatility nearing 30, indicating a risk-reward imbalance [4]. - The primary driver of current tin price valuations is supply-side concerns, particularly regarding the DRC's political situation, which investors should monitor closely [4][5]. - The market is expected to experience high volatility, with prices likely to remain elevated but difficult to sustain significant increases in the short term [5].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The short - term tin supply and demand are in a tight balance. Considering the inhibitory effect of high prices on tin consumption and the marginal relief of the shortage at the mine end, it is expected that tin prices will mainly fluctuate [11][13]. 3. Summary by Relevant Catalogs 3.1. Weekly Assessment and Strategy Recommendation - Cost side: In October, the increment of imported tin concentrates in China was obvious, and the shortage of domestic raw material supply was slightly alleviated. In October, the import volume of tin ore and its concentrates was 11,632 physical tons (equivalent to about 4,938 metal tons), a year - on - year decrease of 15.74% and a month - on - month increase of 43.36%. The import volume from Myanmar was 2,367 tons (equivalent to about 861 metal tons), a year - on - year decrease of 43.64% and a month - on - month increase of 1.50%. The total import volume from other countries in October was 9,266 tons (equivalent to about 4,077 metal tons), a year - on - year decrease of 5.90% and a month - on - month increase of 57.05% [12]. - Supply side: The resumption of tin mines in Wa State, Myanmar is slow, and the export volume remains low. The raw material shortage of smelting enterprises in Yunnan still exists. The short - term operating rate is stable, but there is insufficient upward momentum. In Jiangxi, due to a significant reduction in scrap, the supply of crude tin is insufficient, and the refined tin output continues to be at a low level. In general, it is expected that the overall operating level of smelters in the two places will be difficult to further improve in the short term [12]. - Demand side: Although the consumption performance in traditional fields such as consumer electronics and tinplate is a bit weak, the long - term demand expectations brought by emerging fields such as new energy vehicles and AI servers support tin prices. In the peak season, the operating rate of domestic tin solder enterprises showed a slight warming trend in October. The domestic integrated circuit output in October was 4.18 billion pieces, with a year - on - year growth rate of 17.7%. Downstream enterprises mainly replenish inventory at low prices. The short - term price increase is too large, and the downstream acceptance is limited, resulting in an obvious accumulation of inventory. This week, the total social inventory of tin ingots in major regions in China was 8,245 tons, an increase of 311 tons from last week [12]. 3.2. Futures and Spot Market No specific analysis content provided, only figures 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 fee remains at a low level [26]. 3.4. Supply Side - The production of tin ingot smelters in Yunnan and Jiangxi is generally stable at a high level. The production recovery in Yunnan is obvious, while that in Jiangxi is a bit weak. The shortage of raw material supply is a common constraint for capacity release in both places [12][13]. - According to customs data, in October 2025, the physical volume of imported tin concentrates in China reached 11,632 tons, a slight increase from the previous month. The import volume of tin concentrates from countries such as the Democratic Republic of the Congo has rebounded, and the overall volume meets expectations. The import volume of tin ore from Myanmar decreased slightly in October, but it is expected to increase by more than 2,000 tons in November after the mining license is approved [12][13]. 3.5. Demand Side - The year - on - year growth rate of China's semiconductor sales has slightly rebounded, and the global semiconductor sales maintain high growth [44]. - The tin consumption in the tinplate field continues to decline 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, and PVC stabilizers are a major consumer of tin compounds [55]. - The operating rate of downstream solder enterprises showed a slight warming trend in October, and the domestic integrated circuit output in October was 4.18 billion pieces, with a year - on - year growth rate of 17.7% [12]. 3.6. Supply - Demand Balance - The total social inventory of tin ingots in major regions in China this week was 8,245 tons, an increase of 311 tons from last week [12][13].

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].
