（文华综合） 9月排产稳中有升，当月虽然处于下游的旺季阶段，但从当前情况来看，9月实际消费水平或将较往年下 滑，大部分企业依旧维持观望情况，整体订单水平较8月维持平稳。电子行业由于AI、人形机器人等热 潮或将增加锡焊料的使用量，但整体行业仍处于发展初期，增量需求较为有限，所在的消费领域或将稳 步增长。产业基本以销定产，且经过8月末和9月中的锡价回调后的补库，大部分下游仓库水平逐步回 暖。9月光伏排产维持平稳。总的来看，9月下游锡焊料企业的产量和开工率预期或将小幅回暖。 对于后市，新湖期货评论表示，价格重心回落有利于消费改善。目前终端市场略有回暖迹象，但表现仍 不明显。虽然汽车市场率先回暖，但其他市场总体仍偏弱。不过由于近期龙头企业检修，供应降至相对 低位，国内库存明显去化，这基于锡价下方较强支撑。海外市场近期虽有所累库，但总体仍处于低位。 后期随着消费回升，锡价有望再度反弹。 沪锡震荡上行，主力合约收涨1.5%，报272510元/吨。上周锡价连续回落，现货市场交投略有改善，下 游逢低有补货行为，锡锭社会库存去库明显。基本面供需双弱，缅甸锡矿复产进度缓慢，制约原料供 应，锡下游需求处于从淡季向旺季过度阶段，关注 ...

Group 1 - The core viewpoint indicates that the tin market is experiencing a downward trend, with the main contract falling by 1.46% to 269,100 yuan/ton, influenced by the Federal Reserve's interest rate cut and limited improvement in domestic downstream consumption [1] - Domestic smelting plants are facing reduced operating rates, with a reported operating rate of 28.48% for refined tin smelting enterprises in Yunnan and Jiangxi, marking a year-to-date low [1] - The recovery of tin mines in Myanmar is slower than expected, with significant production unlikely before November, while tin mine inventories in Yunnan are below the 30-day safety line, leading to increased processing costs and some companies experiencing production losses [1] Group 2 - The outlook for the tin market suggests that the combination of the Federal Reserve's dovish statements and hawkish comments will lead to a weak and volatile price trend, with a focus on lower integer support levels [2] - The LME inventory is stabilizing and domestic consumption is not improving, which is dragging down tin prices, while the supply of refined tin remains constrained due to regular maintenance at large smelting plants [2]

Core Viewpoint - Yunnan Tin Company has successfully developed a patented device for efficiently separating tin from molten crude tin, addressing long-standing challenges in the tin smelting industry [1] Group 1: Technological Innovation - The newly patented device is designed to improve the separation process of tin, which has historically faced complex working conditions and low efficiency [1] - The technical team has integrated pneumatic drive and wireless remote control into high-temperature operations, marking a significant advancement in the industry [1] - The new equipment has achieved a sixfold increase in the efficiency of tin extraction operations, significantly enhancing the working environment for employees [1] Group 2: Industry Impact - This innovation fills a technological gap in the tin smelting industry, providing a replicable and scalable solution for green and intelligent upgrades in the sector [1] - The company aims to continue exploring technological innovations to revitalize its century-old operations and contribute to the global tin smelting industry's modernization [1]

对于后市，金瑞期货评论表示，云锡本次检修属前期规划内安排，对市场实际销量扰动有限；同时，高 价对消费的抑制仍在，当前整体消费尚未显现旺季特征，短期锡价大概率延续区间震荡，预计短期延续 震荡格局。 沪锡窄幅波动，主力合约收涨0.08%，报273980元/吨。龙头冶炼企业启动年内常规检修，国内产量下滑 明显，但是消费端未见明显好转，终端表现疲软，国内库存偏高，海外库存处于历史低位，多空因素交 织，市场驱动有限，沪锡延续区间震荡格局。 锡矿供应偏紧格局维持，虽然缅甸佤邦部分企业获采矿许可，但受雨季及设备供应延迟影响，SMM预 计实际出矿量推迟至四季度，非洲矿虽增量但运输周期长且品位波动大，难以缓解短期紧缺。国内冶炼 厂开工率维持低位，云南地区原料短缺问题依旧严峻。有部分前期检修企业筹备复产，但另外一家龙头 企业停产检修，生产对冲后，整体产量或维持下降态势。 （文华综合） 近日锡价震荡回落，冶炼厂出货意愿尚可，实际成交有限。贸易商方面积极入市报价，多反馈当前锡价 虽小幅下滑，但整体仍处高位，下游接货意愿不强，成交整体仍维持刚需，市场整体交投表现平平。下 游订单水平维持下滑态势，当前处于下游消费水平淡季，锡相关消费较往 ...

Group 1 - The core viewpoint of the articles indicates that the tin market is experiencing a strong reality with weak expectations, driven by slow recovery in Myanmar's tin mines and low import levels in China, alongside rising expectations for interest rate cuts by the Federal Reserve [1][2] - The main contract for tin on the Shanghai Futures Exchange rose by 2.31%, reaching 278,650 yuan per ton, marking a four-month high [1] - Domestic smelting plants are facing tight supply from the mining sector, with operating rates difficult to improve, and raw material inventories generally below 30 days [1] Group 2 - The processing fee for 40% grade tin concentrate in Yunnan remains low, and some smelting companies plan maintenance in August, which may further reduce capacity utilization [1] - The circulation of secondary materials in the Jiangxi region has decreased by over 30% year-on-year, leading to a significant shortage of crude tin supply, which restricts the recovery of refining capacity [1] - Despite rising tin prices, downstream demand remains weak, with a decline in orders for home appliances and a significant drop in photovoltaic orders, indicating a need to monitor recovery in demand during the peak consumption months of September and October [1] Group 3 - The two main factors supporting tin prices, namely low overseas inventories and strong structural demand, have not changed significantly [2] - The slow recovery of Myanmar's tin mines due to seasonal and operational constraints, along with tight raw material supplies and concerns over overseas liquidity, are providing a floor for tin prices [2] - Short-term expectations suggest that tin prices will maintain a high-level oscillation, but further significant increases will require additional positive stimuli [2]

Core Viewpoint - The company plans to conduct routine maintenance shutdown starting from August 30, 2025, lasting no more than 45 days, to ensure the safe and effective operation of tin smelting equipment and subsequent stable production [1] Group 1 - The maintenance shutdown is expected to have minimal impact on the annual production plan as it has already been accounted for in the company's budget and production plans for the year [1]

Group 1 - LME prices continue to rise, closing at 34,510, an increase of 1.11% from the previous trading day, marking three consecutive days of gains [1] - The strong performance of tin prices is supported by low global tin inventory and tight supply, with macroeconomic sentiment improving [1][2] - Supply tightness from mining remains a crucial factor for supporting tin prices, with July imports of tin ore in China slightly decreasing compared to June, primarily due to a significant drop in imports from Myanmar [1] Group 2 - China's tin ingot imports are limited, mainly due to profit margins affecting imports, with the current spot import window for refined tin remaining largely closed [2] - The global tin supply recovery is slow, with Indonesian refined tin exports facing challenges, while demand remains relatively stable [2] - Domestic inventory levels are high despite a slight decrease, and weak consumption is unlikely to provide support for prices in the short term [2]

Core Viewpoint - Yunnan Tin Company Limited reported a strong performance in the first half of 2025, with significant increases in revenue and net profit, indicating a positive growth trend in the company's operations [1] Financial Performance - The company achieved an operating revenue of 21.093 billion yuan, representing a year-on-year growth of 12.35% [1] - The net profit attributable to shareholders reached 1.062 billion yuan, marking a year-on-year increase of 32.76% [1] - The net profit excluding non-recurring items was 1.303 billion yuan, reflecting a year-on-year growth of 30.55% [1] Operational Strategy - Yunnan Tin Company focused on seizing market opportunities and continuously expanding raw material supply channels to ensure stable production [1] - The company leveraged the synergy between its mining and smelting operations, enhancing overall efficiency in metal recovery [1] - A "dual-channel" raw material procurement strategy was implemented, stabilizing traditional ore procurement while actively exploring secondary material resources to strengthen supply chain resilience [1] Production and Efficiency - The company optimized mining and selection processes, improved site management, and refined waste disposal techniques to address challenges in ore output and quality [1] - Overall, Yunnan Tin Company successfully met its production and operational targets, maintaining a steady and positive development trend [1]
