供需紧平衡，关注缅甸锡矿复产进展

Group 1: Report Industry Investment Rating - No information provided Group 2: Core Viewpoints of the Report - The supply - demand of tin is in a short - term tight balance. In the global macro - loose cycle, the medium - term demand is not pessimistic. However, in the short term, there is an expected increase in supply due to the resumption of tin mines in Myanmar, and the growth of tin demand from consumer electronics is not obvious. So, it is not recommended to chase high prices, and buying on dips may have a higher probability of success [2][16] Group 3: Summary by Relevant Catalogs Supply - side - In September 2025, the refined tin output was 9,770 tons, a month - on - month decrease of 34.69% and a year - on - year decrease of 2.3%. From January to September 2025, the cumulative refined tin output was 127,400 tons, with a cumulative year - on - year decrease of 0.95%. The smelter's operating rate in September was 38.6%, and some enterprises had maintenance in September [5] - In Yunnan, most smelters' output decreased month - on - month, with some having maintenance and production stagnation, and the tin ore supply was still tight. In Guangxi, enterprises' output decreased significantly due to maintenance and tight raw materials. In Jiangxi, the smelter output decreased slightly due to tight raw materials and policy reasons [5] - In October 2025, as large smelters resume production and most sample enterprises maintain stable operation, the domestic refined tin output is expected to rise to about 14,500 tons [5] - Due to the slow increase in the output of tin mines in Wa State, Myanmar, China's overall tin ore imports remain at a low level, and tin ingot supply has been low. In the fourth quarter, tin ingot supply may increase significantly after the supply of tin mines in Myanmar gradually expands [2][16] Demand - side - In Q3 2025, the global PC shipments increased by 10% year - on - year, the highest since the peak demand during the 2022 pandemic. The growth rate of mobile phone consumption rebounded slightly, with a year - on - year increase of 2%. IDC predicts that the global smartphone shipments in 2025 will increase by 0.6% year - on - year to 1.24 billion units. The emerging 3C electronic consumption areas driven by AI are still in the initial stage and have little impact on overall demand [8] - The construction of 5G communication equipment and large - scale data center servers requires a large number of circuit boards and connection components, and the tin consumption is increasing steadily. With continuous investment in global AI - related capital expenditure, the server scale is growing rapidly. IDC data predicts that AI server shipments will increase by 26% year - on - year to 1.895 million units in 2025 and continue to grow in 2026 [8] - In September 2025, China's automobile sales reached 3.226 million, a record high for the same period, with a year - on - year increase of 14.9%. New energy vehicle sales were 1.604 million, a year - on - year increase of 24.6% [8] - Other non - semiconductor demand is relatively stable. Tin consumption in the tinplate field has declined slightly as aluminum cans have almost completely replaced tinplate cans in the beverage packaging field. The output of PVC has increased slightly year - on - year in the first three quarters, and PVC stabilizers are a major consumer of tin compounds [12] - Downstream new energy vehicles and AI servers continue to be booming, traditional consumer electronics and home appliances are experiencing a mild recovery, while the photovoltaic field is relatively weak due to over - capacity and trade frictions [2][16]
