1. Report Industry Investment Rating No information provided. 2. Core View of the Report - In November, tin prices continued to strengthen under the influence of supply disturbances at the mine end, reaching a new high for the year. Although the current demand in the tin market is weak, with low downstream inventories and limited bargaining power, supply - side disturbances are the determining factor for short - term prices. Therefore, it is more likely that tin prices will fluctuate strongly in the short term [11][13]. 3. Summary of Each Section According to the Table of Contents 3.1 Monthly Evaluation and Strategy Recommendation - Cost side: In October, the import volume of tin concentrates in China increased significantly, and the shortage of raw material supply was slightly alleviated. However, the recent deterioration of the conflict in the Democratic Republic of the Congo has disrupted tin ore transportation, raising market concerns. In October, the import volume of tin ore and 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% [12]. - Supply side: The resumption of tin mines in Wa State, Myanmar, has been slow, with low export volumes. Smelting enterprises in Yunnan still face a shortage of raw materials, and their short - term operating rates are stable but lack further upward momentum. In Jiangxi, due to a significant reduction in scrap materials, the supply of crude tin is insufficient, and refined tin production remains at a low level. Overall, it is expected that the overall operating level of smelters in the two regions will be difficult to further improve in the short term [11][12]. - Demand side: Although the consumption in traditional fields such as consumer electronics and tinplate is slightly 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 recovery in October. In October, the domestic integrated circuit output was 4.18 billion pieces, with a year - on - year growth rate of 17.7%. Downstream enterprises mainly replenish inventory at low prices. Recently, due to the large short - term price increase, downstream acceptance is limited, and inventories have increased significantly. This week, the total social inventory of tin ingots in major Chinese regions was 8,245 tons, an increase of 311 tons from last week [11][12]. 3.2 Futures and Spot Market No specific text analysis content provided, only relevant data graphs are presented [17][19][20]. 3.3 Cost Side No specific text analysis content provided, only relevant data graphs are presented, including the monthly output of Chinese tin ore, import volume, tin concentrate price, and tin concentrate processing fee [22][24][26]. 3.4 Supply Side No specific text analysis content provided, only relevant data graphs are presented, including domestic refined tin monthly output, domestic recycled tin monthly output, tin production and operating rate in Yunnan and Jiangxi regions, refined tin export and import profits, domestic refined tin import volume, and Indonesia's refined tin import and export [28][30][32][36][38][39]. 3.5 Demand Side - The year - on - year growth rate of China's semiconductor sales has rebounded slightly, and global semiconductor sales have maintained high growth [45]. - No specific text analysis content provided for other indicators, only relevant data graphs are presented, including domestic computer and smartphone production, output of household appliances (washing machines, air conditioners, refrigerators, color TVs), China's photovoltaic cell output and photovoltaic installation, domestic key enterprise tin - plated strip production, domestic PVC monthly output, downstream solder enterprise operating rate, and domestic apparent tin consumption [42][44][47][49][51][53][55][57]. 3.6 Supply - Demand Balance (Inventory) No specific text analysis content provided, only relevant data graphs are presented, including Chinese social inventory and LME inventory [59][60][61].

Industry Analysis and Outlook on Tin Key Points Industry Overview - Domestic hidden inventory of tin is continuously depleting, with an expected peak gap of approximately 15,000 tons by July 2025, indicating a tight supply situation that is unlikely to ease in the short term, thus supporting tin prices [1][2] - Myanmar's tin mines are expected to gradually resume operations starting August 2025, with production anticipated to reach around 1,500 tons by November, but the recovery pace is slow, and the supply gap will only improve by about 2,000 tons by year-end, which is insufficient for a relaxed supply state [1][3] Supply Forecast - Global tin supply is expected to become more relaxed in 2026, with Myanmar's production potentially recovering to between 26,000 tons and 32,000 tons, and Indonesia's tin ingot exports possibly reaching between 65,000 tons and 72,000 tons, while Africa also has production potential, albeit with uncertainties due to policy and investment environments [1][5][10] - The active replenishment demand in the supply chain will absorb some raw material increments, meaning that even if raw material increments reach between 16,000 tons and 30,000 tons, the actual increase in smelting output may be reduced by about 10,000 tons, potentially affecting market supply-demand balance [1][8] Policy and Market Dynamics - Indonesia's tin mining policy adjustments, including foreign exchange controls, quota regulations, and anti-smuggling measures, may lead to a gradual decline in overall supply stability as the world's second-largest tin ingot supplier, necessitating ongoing attention to long-term impacts [1][9] - The political and investment environment in Africa presents significant uncertainties for long-term supply, despite the region's potential for increased production due to low extraction costs and high grades [1][10] Demand Trends - Tin demand is primarily concentrated in consumer products such as electronic solder (40%) and packaging materials (10%), with a strong correlation to economic cycles. Emerging demand areas include electric vehicles, photovoltaics, and AI servers, but their current market share remains limited [1][13][14] - Global tin demand growth is projected to slow to around 3% in 2025, with a potential range of -1% to 1% in 2026, indicating a cautious outlook for demand in the coming years [1][18][19] Price Dynamics - The relationship between supply and prices is expected to remain constrained, with new products and applications driving higher demand elasticity. Annual supply-demand balance and mismatches will be more significant for price assessments, with macroeconomic factors playing a substantial role in pricing [1][21][22] - Seasonal price increases typically occur at year-end due to reduced supply from major producing countries during the Chinese New Year and increased pre-holiday stocking by downstream enterprises [1][23] Regional Insights - The Democratic Republic of the Congo (DRC) has experienced supply disruptions due to conflict, but major mines remain largely unaffected. The establishment of new smelting facilities by the U.S. is expected to improve local production conditions [1][27] - South American tin production is projected to be stable, with Peru, Bolivia, and Brazil producing approximately 33,000 tons, 21,000 tons, and 19,000 tons respectively in 2024, although economic and operational uncertainties may impact stability [1][30] Conclusion - The tin industry faces a complex landscape of supply constraints, policy changes, and evolving demand dynamics. Investors should remain vigilant regarding market fluctuations and potential risks associated with geopolitical factors and economic cycles.
