1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report This week, tin prices rebounded slightly from a low level. Supply remains tight, with the slow resumption of tin mines in the Wa State of Myanmar and insufficient raw materials for smelting enterprises. Although the mining licenses in the Wa State have been approved, the tin ore export volume is still far below the normal level due to the rainy season and slow actual resumption progress, failing to effectively make up for the supply gap. In September 2025, China's imported tin concentrate physical volume decreased significantly compared to the previous month. On the 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 September, the operating rate of domestic tin solder enterprises showed a slight recovery. Downstream enterprises mainly replenish inventory at low prices. The social inventory of major tin ingots decreased this week. Overall, the tight supply situation supports tin prices, and it is expected that tin prices will remain stable or rebound slightly [11][13]. 3. Summary by Directory 3.1. Weekly Assessment and Strategy Recommendation - **Cost End**: Although the mining licenses in the Wa State of Myanmar have been approved, the resumption progress is slow, and significant recovery of tin ore supply is expected in the fourth quarter. In September 2025, China's imported tin concentrate physical volume was 8,714 tons, a significant decline from the previous month. The import volume from countries such as the Democratic Republic of the Congo has decreased, but the overall volume is at a normal level, only affected by shipping factors. The import volume from Myanmar is increasing, and short - term supply shows signs of improvement. The import volume from other regions and countries remains at the previous level [12]. - **Supply End**: The resumption of tin mines in the Wa State of Myanmar is slow and difficult to increase production before November. The raw material shortage of smelting enterprises in Yunnan still exists, and the processing fee (TC) for 40% grade tin concentrate in Yunnan remains low. 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. The raw material inventory of domestic smelters is generally less than 30 days, and some enterprises carried out maintenance in September, with the capacity utilization rate likely to remain low [12]. - **Demand End**: 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 September. Downstream enterprises mainly replenish inventory at low prices. This week, the total social inventory of major tin ingots was 7,743 tons, a decrease of 182 tons from last week [12]. 3.2. Futures and Spot Market No specific analysis content provided, only relevant charts are presented, including the basis of Shanghai tin main contract and the LME tin premium (0 - 3) [19][20]. 3.3. Cost End Tin ore supply is tight in the short term, and processing fees remain at a low level [27]. 3.4. Supply End The resumption of tin mines in the Wa State of Myanmar is slow, and the raw material shortage of smelting enterprises in Yunnan and Jiangxi persists, resulting in a low level of refined tin output and a low capacity utilization rate of domestic smelters [12]. 3.5. Demand End - The year - on - year growth rate of China's semiconductor sales has rebounded slightly, and global semiconductor sales have maintained high growth [45]. - Tin consumption in the tinplate field continues to decline, mainly 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 [56]. - The operating rate of downstream solder enterprises showed a slight recovery in September, and downstream enterprises mainly replenish inventory at low prices [12]. 3.6. Supply - Demand Balance This week, the total social inventory of major tin ingots was 7,743 tons, a decrease of 182 tons from last week [12].

Summary of GaN and Power Semiconductor Expert Meeting Industry Overview - The GaN (Gallium Nitride) technology is gaining an advantage in high-power applications, particularly in the range of 1 kW to 10 kW, outperforming SiC (Silicon Carbide) in terms of cost-effectiveness. The market potential is expected to reach tens of billions or even hundreds of billions in the future, primarily for applications in AI servers with 800V power supply architecture [1][3]. Key Points GaN Technology and Market - GaN devices are particularly advantageous in the 800V DC power supply architecture, with 1,000W being the threshold where GaN shows lower losses compared to Si-based IGBTs (Insulated Gate Bipolar Transistors). Above 1,000W, GaN's cost-effectiveness becomes more pronounced, especially at the 3,000W level [1][3]. - The global leader in GaN manufacturing is Innoscience, holding approximately 30% market share, with products ranging from 100V to 1,200V. The company has been validated by NVIDIA but faces production limitations due to TSMC's process and advanced packaging technology [1][6][10]. Technical Aspects - GaN devices primarily utilize two technical routes: depletion-mode (D-mode) and enhancement-mode (E-mode), with E-mode being the mainstream choice due to its market applicability [12]. - GaN faces challenges in high-voltage applications, particularly concerning leakage current and heat generation. In contrast, SiC offers superior thermal conductivity and reliability in high-pressure scenarios [13][14]. Competitive Landscape - The current market for GaN is characterized by a lack of profitability among most manufacturers due to insufficient capacity and limited demand. For instance, Innoscience's annual production capacity is 15,000 wafers, while its design capacity could reach 65,000 to 78,000 wafers [15]. - The exit of TSMC from the GaN foundry business is seen as beneficial for mainland manufacturers, as it allows for cost reductions and market expansion opportunities [21]. Pricing Trends - The pricing of GaN and SiC devices is on a downward trend. For example, a 75A GaN device costs around 15 to 20 RMB, while SiC devices are priced significantly higher, making GaN a more attractive option in terms of performance and cost [5][16]. - The price of 8-inch GaN wafers has fallen below that of 6-inch wafers, enhancing their competitiveness in the market [22]. Future Outlook - The demand for power semiconductors is expected to grow significantly, driven by sectors such as renewable energy storage and data centers, with projections indicating a potential doubling of demand [19][20]. - The long-term outlook for GaN pricing will depend on increased market demand and production capacity, which could stabilize prices and lead to profitability for manufacturers [15]. Additional Insights - The competitive dynamics in the semiconductor market are shifting, with domestic companies poised to benefit from the exit of established players like Infineon and the sanctions on companies like Ansem Semiconductor, which could create opportunities for local firms to capture market share [17][24].
