1. Report Industry Investment Rating No relevant information provided. 2. Core View of the Report - The global tin ore cost center is expected to rise, with a structural increase in costs. The direct cash cost is expected to grow steadily by 55% in 8 years, and the full cost will more than double [3][5]. - Tin ore (ingot) costs vary across different regions in China. Costs in most regions around the world are rising, with a significant gap between high - and low - cost production areas. Currently, tin prices have a certain premium compared to mine - end costs, and the pricing logic has shifted [31][34][37]. 3. Summary by Directory Global Tin Ore Cost Overview - According to ITA statistics, in 2022, the 90th - percentile cash cost and full cost of global tin ore were $23,171/ton ($161,164/ton) and $25,581/ton ($177,926/ton) respectively. It is expected that by 2030, they will rise to $36,000/ton ($250,394/ton) and $54,000/ton ($375,592/ton) [5]. China - Tin ore resources are mainly distributed in Yunnan, Guangxi, and Inner Mongolia. Representative companies are Yunnan Tin, Xingye Yinxing, and Huaxi Non - ferrous. In 2024, Yunnan Tin's tin ingot cost was about 165,500 yuan/ton, with a 3 - year CAGR of - 6.71%; Huaxi's tin concentrate cost was about 92,200 yuan/metal ton, with a 2 - year CAGR of 5.57%; Xingye's tin production cost was about 43,700 yuan/ton, with a year - on - year growth rate of - 27.78% [9]. Myanmar (Wa State) - In the long - term, as mining continues, the open - pit tin mines in Myanmar are shifting to underground mining, resulting in higher costs and lower ore grades. Currently, low ore grades (down to 1% - 2%, some as low as 0.8%), shortages of supplies, and a 30% physical tax are pushing up the cost of tin ore mining [10][12]. Indonesia - Indonesia is the world's second - largest tin - reserve country. PT Timah, the largest tin company in Indonesia, has seen a decline in tin ore production in recent years. The cash cost of tin ingots has decreased from about 157,032 yuan/ton in 2022 to 124,390 yuan/ton in 2024, but it is still relatively high compared to low - cost production areas in Africa [16]. Congo (Kinshasa) - The Bisie tin mine is the largest core mine in Congo (Kinshasa) and one of the highest - grade tin mines in the world, with significant low - cost characteristics. Although the ore grade has declined in recent years, it remains above 3%. The AISC cost has increased in the past two years, with a 4 - year CAGR of about 2.92% [22]. Australia (Renison Project) - Renison is the only operating tin mine in Australia. In 2024, its tin production was 11,006 tons, accounting for about 2.94% of the global total. The AISC cost in 2024 was about 140,778 yuan/metal ton, with a 3 - year CAGR of about 9.57%, but it is still significantly lower than the current tin price [27]. South America - Peru's San Rafael tin mine has a cash cost of about 40,931 yuan/metal ton, with a 3 - year CAGR of about - 1.61%. Brazil's Pitinga tin - niobium - tantalum polymetallic mine, after including niobium - tantalum ore costs, has a cash cost of about 108,760 yuan/metal ton, with a 3 - year CAGR of about + 19.50% [30]. Global Cost Comparison - Most regions around the world are experiencing cost increases, except for Peru, Indonesia (tin ingots), and some Chinese companies. High - cost tin mines are mainly in Asian regions such as Myanmar, while low - cost tin mines are in African regions such as Congo (Kinshasa), Australian regions, and South American regions such as Brazil and Peru [34]. Tin Price and Cost Relationship - According to ITA predictions, by 2027, the 50th - percentile, 75th - percentile, and 90th - percentile lines of the global tin ore full - cost curve will be slightly above $20,000/ton, about $25,000/ton, and about $33,800/ton respectively. As of the end of January 2026, the LME 3M tin price has reached about $55,000/ton, higher than the full cost of 95% of tin mines, providing profit margins for most tin mines. The tin price has deviated from the 90th - percentile cost, indicating a shift in the pricing logic [37].

Core Viewpoint - The tin metal market is experiencing a significant price surge, continuing the upward trend from 2025, with prices reaching historical highs due to a combination of geopolitical conflicts, supply constraints, and long-term demand expectations [1][4][5]. Price Trends - On January 26, 2026, the main contract for tin futures on the Shanghai Futures Exchange rose over 10%, reaching approximately 462,700 yuan/ton, and closed at 425,300 yuan/ton, marking a 1.37% increase from the previous trading day and over 25% increase for the month [1]. - The LME three-month tin price hit a record high of about $55,400 per ton (approximately 358,200 yuan/ton) on January 23, 2026, up 6.5% from the previous day [1]. Supply Constraints - The current geopolitical situation in the Democratic Republic of Congo has escalated, increasing safety risks in the main production areas, compounded by slow recovery in Myanmar and uncertainties in Indonesian policies, creating a "triple constraint" on supply [5]. - Global tin inventories are at historically low levels, with LME tin inventory at 7,195 tons, a 21.23% increase month-on-month, while domestic social inventory has accumulated to 9,700 tons, up 0.18% [6]. Demand Dynamics - There is a clear distinction in demand, with short-term pressures due to the traditional off-season and high prices, while long-term growth is driven by AI computing, photovoltaic new energy, and electric vehicles, which are expected to significantly outpace traditional sectors [3][7]. - Analysts suggest that while there is a strong long-term growth expectation for tin demand, the immediate consumption is being suppressed by seasonal factors and high prices [7]. Future Price Outlook - Short-term factors supporting high tin prices include a weak dollar environment, supply concerns due to geopolitical conflicts, and positive market sentiment, which may lead to further price increases [8]. - Analysts from Huatai Futures indicate that the sensitivity of high-tech companies to interest rate cuts could benefit tin demand, supported by rising capital expenditures in the semiconductor sector [8]. - Future price rationalization is anticipated, with expectations of increased tin supply from recovering mines, projecting an increase of 23,000 to 25,000 tons in 2026, which may alleviate some upward price pressures [9].

Core Viewpoint - The recent surge in tin prices, with the Shanghai tin futures contract exceeding 380,000 yuan/ton, is driven by a combination of tight supply and optimistic long-term demand outlooks, despite no significant changes in the fundamental supply-demand dynamics [1][3][8]. Supply Overview - Tin prices have risen sharply from 300,000 yuan/ton to over 370,000 yuan/ton since November 2025, marking an increase of over 23% and approaching the historical high of 390,000 yuan/ton from 2022 [1]. - Domestic tin ore production from January to October 2025 was 61,800 tons, a year-on-year increase of 0.7%, while imports of tin ore decreased by 21.7% to 118,000 tons during the same period [3]. - The supply concerns are exacerbated by geopolitical tensions in regions like the Democratic Republic of the Congo and Indonesia, which have not yet significantly impacted major mining operations but continue to create uncertainty [4][13]. Demand Overview - Domestic apparent consumption of refined tin from January to November 2025 was 161,000 tons, down 5.8% year-on-year, with November consumption dropping 33.7% compared to the previous year [6]. - Despite a seasonal decline in demand from consumer electronics, emerging sectors such as electric vehicles and AI servers are providing some support to tin solder manufacturers, maintaining stable operating rates [6][10]. Inventory Insights - As of January 9, 2026, social inventory of tin ingots in major markets was 8,076 tons, a decrease of 1,233 tons from the previous week, indicating a continued trend of inventory reduction [6]. - The decline in inventory is attributed to low incoming supplies and extended delivery times from smelters, coupled with low downstream inventory levels prompting restocking [6]. Market Perspectives - Analysts suggest that the current tin price rally is supported by a combination of immediate supply tightness and long-term optimistic demand forecasts, particularly driven by advancements in AI and technology sectors [8][10]. - The macroeconomic environment, including a weak dollar and favorable policies in China, is expected to provide further support for tin prices, with projections indicating that prices may remain elevated in the near term [9][12].

1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints of the Report - In 2026, it is predicted that the US dollar will remain relatively volatile, and its impact on tin prices throughout the year will be relatively neutral. The first half of 2026 will be in a shortage pattern of weak supply and demand, and there will be marginal relaxation around the middle of the year as Wa State in Myanmar resumes production. The supply side will see significant incremental releases, with marginal relaxation mainly from the resumption of production in Wa State, Myanmar, and increased production in Indonesia. Attention should also be paid to disturbances in African producing areas such as the Democratic Republic of the Congo, and the supply pattern may be tight in the first half and loose in the second half. The demand side shows that the AI sector has a fast growth rate but a small base, while most terminal demands remain sluggish. Globally, the supply in 2026 will be 369,000 tons with a growth rate of 0.3%, the total demand will be 378,000 tons with a growth rate of -0.8%, and the supply-demand balance gap will be 9,000 tons. In China, the supply will be about 182,000 tons, the demand will be about 185,000 tons, and there may be a supply-demand gap of 3,000 tons. The strategy recommends a buy-on-dip approach in the first half of the year, closely monitoring overseas production increases or disturbances, and suggests an option strategy mainly based on buying calls, as well as considering internal-external positive arbitrage and inter-month positive arbitrage strategies [2][109][111]. 3. Summary According to the Table of Contents 3.1 2025 Tin Price Trend Review - In 2025, the overall price center of Shanghai Tin showed an obvious upward trend. Frequent disruptions in major producing countries such as Myanmar, the Democratic Republic of the Congo, and Indonesia, combined with the start of the macro - interest rate cut cycle and the improvement of semiconductor prosperity, jointly drove the tin price up. By December 18, the annual increase of Shanghai Tin was 36.68%, making it the top - gainer among the six non - ferrous metals. In the overseas market, the increase of LME Tin was even stronger, with a 48.54% increase in the 3M futures by December 17. In terms of positions and trading volume, by December 12, the position of Shanghai Tin was 118,433 lots, at a high level in the past year, and the weekly trading volume was 1,606,972 lots, also at a high level compared with the same period in history. The price fluctuations can be divided into three stages: from New Year's Day to around Tomb - Sweeping Festival, the price fluctuated upward and then rose sharply; from after Tomb - Sweeping Festival to mid - year, the price dropped significantly and then recovered; in the second half of the year, the price started to rise and showed a smooth upward trend [6][11][14]. 3.2 2026 Tin Fundamental Market Outlook 3.2.1 US Dollar Index - It is expected that the US dollar will remain relatively volatile in 2026, with a relatively neutral impact on tin prices throughout the year. Attention should be paid to whether the restart of the US government in Q1 2026 can bring compensatory growth. The US dollar index is considered to be in a relatively balanced state in both the medium - long - term and short - term valuation systems, with limited one - sided driving forces. The annual fluctuation range of the US dollar index is expected to be 96 - 108, with an upward - risk bias, and the Q1 2026 fluctuation range is 97.7 - 102. The judgment on the US dollar in 2026 is based on the current balanced valuation. Factors such as economic relative strength, monetary policy expectations, carry trading, and currency group strength differentiation should be considered [18][19]. 3.2.2 Supply Side - **Myanmar Wa State**: The resumption of production in Wa State has been delayed, and the release of incremental production is slow. The current production suspension can be traced back to April 2023, lasting for more than two years. Although some mining licenses were approved in July 2025, the actual resumption progress is still slow. The factors affecting the resumption include the increase in production costs due to the 30% physical tax, the difficulty in recovering the mining scale, and short - term marginal improvement after the end of abnormal weather. It is expected that the year - on - year decline in monthly shipments will gradually narrow, and the market generally expects the resumption of production around June 2026. The estimated annual incremental import of tin ore from Myanmar to China in 2026 compared with 2025 is about 5,190 metal tons, mainly concentrated in the second half of the year [23][26][28]. - **Democratic Republic of the Congo**: The armed conflict led by the M23 armed organization has escalated, threatening the production and transportation of the Bisie tin mine. It is expected that the recent conflict will bring a marginal reduction of about 1,750 tons in 2026 production. If the impact in 2026 is similar to that in 2025, the conflict is expected to cause a marginal reduction of about 1,750 tons, and the increase in production will be hindered, with an impact of about 400 tons on China's imports [35][36]. - **Other Countries**: In 2025, the import of tin ore from some countries increased. From January to October 2025, the import of tin ore from Australia increased by 6.68% year - on - year (an increase of 1,421.49 tons), from Nigeria by 71.14% (an increase of 6,552.78 tons), and from Bolivia by 81.81% (an increase of 6,249.73 tons). In 2026, if Myanmar's imports increase year - on - year and other countries continue to grow, the overall import may have a large increase. However, there is uncertainty in Nigeria's mining suspension plan, and Bolivia is expected to achieve steady growth [42][43]. - **Global New Capacity Expansion**: In 2026, the new tin mine projects that may be put into production have an annual capacity of about 13,160 tons, and about 6,660 tons are relatively certain. In 2027, it is about 8,950 tons, and there are also 18,200 tons with undetermined production times. Some projects have a risk of delay, such as the Rentails project in Australia and the impact of the acquisition of Atlantic Tin by Xingye Yinxing on the Achmmach tin mine [56][57][59]. - **Indonesia**: In 2025, the export of tin ingots in Indonesia increased significantly. From January to October 2025, the export of tin ingots was 40,134 tons, a year - on - year increase of 14.72%. It is expected that the production of tin ingots in Indonesia will continue to grow in 2026, with the state - owned enterprise PT Timah planning a production of 30,000 tons in 2026, an increase of 8,500 tons compared with 2025. The export of tin ingots is expected to be 55,000 - 60,000 tons in 2026, with an increase of about 6,500 tons. However, the first quarter of 2026 is the seasonal off - season for tin ingot exports in Indonesia [62][63]. - **Domestic**: In 2025, the production of domestic tin ingots was restricted by raw material supply, with a year - on - year decline of 2.91% from January to November. The average operating rate of domestic refined tin enterprises in November was 66.3%, a year - on - year decline of 4.2 percentage points and a month - on - month decline of 0.51 percentage points. In 2026, the growth of tin ingot production still depends on the raw material supply led by the resumption of production in Wa State, Myanmar. The tax policy uncertainty brought by Document No. 770 has affected the production of recycled tin, and the production of recycled tin ingots from January to November 2025 decreased by 21.19% year - on - year. If the tax problem is not resolved in 2026, the production of recycled tin will still face a decline [68][69]. 3.2.3 Demand Side - **AI Field**: In 2025, the AI investment of technology giants continued to heat up, and the data center business of leading chip manufacturers achieved high growth. It is expected that this field will maintain high growth in 2026, providing an increase in demand for tin solder. The estimated tin consumption in data centers in 2026 is about 512 tons, which is not large in scale but has long - term growth potential [74][83]. - **Consumer Electronics**: In 2025, the global consumer electronics market was divided. The smartphone market was sluggish, with the global smartphone shipments increasing by only 1.56% year - on - year in the first three quarters, and it is expected to decline by 0.9% in 2026. The PC market entered an iteration cycle due to the end of Microsoft's support for Windows 10, and the shipments increased by 7.12% year - on - year in the first three quarters. In 2026, the squeezing of upstream memory capacity by AI may affect the consumer electronics market, and the increase in memory prices may lead to a small decrease of less than 1% in market demand [84][86][87]. - **Photovoltaic**: In 2025, the new policies in the photovoltaic field led to a rush - to - install boom in the first half of the year, but the new installations decreased significantly in the third quarter. In 2026, affected by the high - base effect and the promotion of electricity price marketization, the new installations in the photovoltaic field are expected to be flat. It is estimated that the new domestic photovoltaic installations in 2026 will be 200GW, a year - on - year decrease of 33%, and the new overseas installations will be 293GW, a year - on - year increase of 11%. Globally, the new installations are expected to be about 493GW, a year - on - year decrease of 13%, and the tin demand in the photovoltaic field will decrease by 18.8% [95][96][97]. - **Electric Vehicles**: In 2026, the growth rate of the global electric vehicle demand will tend to be moderate, and the improvement of the market penetration rate of the structural market is the core logic. It is estimated that the global total sales of electric vehicles will increase by 13% year - on - year to 23.75 million units, and the domestic demand in China will increase by 11% to 15.66 million units. The tin demand in 2026 is expected to increase by 3.9% year - on - year. China, Western Europe, and emerging Asian regions are the core driving regions, while the American market may have a negative impact [106].

1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints of the Report - This week, tin prices broke through upwards, surpassing the 300,000 range with a weekly increase of over 4%. The price increase was mainly driven by macro funds. The stabilization of the previous decline in US stocks and the recovery of AI stock valuations, combined with the renewed turmoil in the Democratic Republic of the Congo on the supply side and macro sentiment, pushed up the price. However, the fundamentals may not support the price increase. After the price rises, domestic social inventories continue to accumulate, domestic spot premiums decline, and the tin Back structure deepens. Currently, the market open interest has reached a historical high, and the market capital strength may weaken. It is believed that the increase in tin prices may slow down, and there is a risk of weekly adjustment [3][5]. 3. Summaries According to Relevant Catalogs 3.1 Trading Aspect (Price, Spread, Inventory, Capital, Transaction, Open Interest) 3.1.1 Spot - This week, the LME 0 - 3 premium was $70 per ton, and the domestic spot premium was 50 yuan per ton.

This week, the Philadelphia Semiconductor Index rebounded, showing the same trend as tin prices [66][68][71].

Summary of Key Points from the Conference Call Industry Overview - **Industry**: Tin Mining Industry - **Key Supply Issues**: The tin supply is facing significant challenges due to reduced exports from Myanmar and Indonesia, which together account for a substantial portion of global tin supply. Myanmar's exports have dropped to half of normal levels due to anti-corruption actions, potentially affecting 10% of global supply if conditions do not improve by 2026 [1][2][12]. Core Insights and Arguments - **Myanmar's Export Challenges**: Myanmar's tin exports to China were only 20% of pre-production levels in October, with expectations for slow recovery due to seasonal weather impacts [1][2]. - **Global Tin Resource Scarcity**: The static reserve-to-production ratio for tin globally is projected to be only 16 years, with China's ratio at 14 years, indicating a high vulnerability in supply due to concentrated resource distribution [1][4]. - **China's Tin Supply-Demand Gap**: China's tin production is declining while refined tin demand is increasing, leading to a projected supply gap of 120,000 tons in 2024, which is over 63% of total demand [1][9]. - **Rising Tin Prices**: The recent increase in tin prices is attributed to supply disruptions and rising demand for tin solder, particularly driven by the AI wave, with expectations for solder demand to grow from 220,000 tons in 2024 to 320,000 tons by 2030, at a CAGR of 6.4% [2][16]. Additional Important Insights - **Investment and Production Trends**: Major Chinese tin companies are enhancing production capabilities, with significant increases in output reported by companies like Yunnan Tin and Xinyi Silver [7][8]. - **Future Supply Projections**: The majority of new tin mining projects are in early stages, with limited certainty of expansion, necessitating high incentive prices to support future production [14][20]. - **Recycling Limitations**: Global recycled tin supply remains limited, contributing to the overall supply constraints in the market [15]. - **Investor Recommendations**: Given the improving cash flows and attractive valuations in the tin industry, investors are advised to focus on companies with low market capitalization relative to reserves and production, which are expected to perform well in the future [21].

1. Report Industry Investment Rating - No information provided in the document. 2. Core Viewpoints of the Report - This week, the tin price broke through the 300,000 yuan range, mainly driven by macro - funds. The stabilization of the previous decline in US stocks, the recovery of AI stock valuations, and the resurgence of turmoil in the Democratic Republic of the Congo on the supply side, combined with macro - sentiment, pushed up the price. However, the fundamentals alone are insufficient to support the price above 300,000 yuan, but the overall price remains resilient [3][5]. 3. Summary According to Relevant Catalogs 3.1 Transaction Aspect (Price, Spread, Inventory, Funds, Transaction Volume, Open Interest) - **Spot**: This week, the LME 0 - 3 premium was $123 per ton, and the domestic spot premium was 250 yuan per ton.
