1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - This week, tin prices declined and adjusted. In terms of supply, the seasonal maintenance work of large - scale smelters in Yunnan was basically completed, and the smelter operating rate increased to some extent, but the overall operating level was still at a historical low. The core issue was the continuous shortage of tin ore raw material supply. Although the mining licenses in Wa State, Myanmar, had been approved, affected by the rainy season and the slow actual resumption of production, the tin ore export volume was still far below the normal level and could not effectively make up for the supply gap. In terms of demand, the long - term demand expectations brought by emerging fields such as new energy vehicles and AI servers provided support for tin prices, but currently, their scale was not sufficient to fully offset the weak consumption in traditional fields. The spot market trading was light, and downstream enterprises had limited acceptance of prices above 280,000 yuan/ton, mostly choosing to make small - quantity purchases for rigid needs, and the overall market trading atmosphere was not strong. In terms of inventory, the total social inventory of tin ingots in major regions across the country this week was 7,925 tons, an increase of 141 tons from last week. In summary, the short - term tin supply remained tight, and tin prices were expected to remain stable or rebound slightly [12][13]. 3. Summary According to Relevant Catalogs 3.1. Weekly Assessment and Strategy Recommendation - Cost side: Although the mining licenses in Wa State, Myanmar, had been approved recently, the resumption of production was slow, and it was expected that the tin ore supply would not be significantly restored until the fourth quarter. In August 2025, China's imported physical volume of tin concentrate reached 10,267 tons, the same as the previous month. The volume of imported tin concentrate from countries such as the Democratic Republic of the Congo, Russia, and Bolivia had declined, but the overall volume was at a normal level, only affected by shipping factors such as the shipping schedule. The volume of imported tin ore from Myanmar had increased, and with the approval of the mining license, there were signs of short - term supply improvement. The volume of imported tin ore from other regions and countries remained at the previous level [12]. - Supply side: The resumption of production of tin mines in Wa State, Myanmar, was slow and difficult to increase production before November. The shortage of raw materials for smelting enterprises in Yunnan still existed. Coupled with the maintenance of a large - scale smelting enterprise in September, the operating rate in Yunnan dropped significantly this week. In Jiangxi, due to a significant reduction in scrap and insufficient supply of crude tin, the refined tin output continued to be at a low level. According to third - party data, it was expected that the domestic refined tin output in September would decrease by 29.89% month - on - month [12]. - Demand side: The new energy vehicle and AI server sectors downstream continued to be booming, but the demand in the traditional consumer electronics and home appliance sectors, which accounted for the majority of demand, remained sluggish. According to the latest production scheduling report of three major white goods released by Industry Online, the total production scheduling volume of air conditioners, refrigerators, and washing machines in September 2025 was 27.07 million units, a 7.2% decrease compared with the actual production volume in the same period last year. In the short term, with the arrival of the traditional peak seasons of "Golden September and Silver October", downstream consumption improved marginally. In August, the operating rate of tin solder of domestic sample enterprises rebounded to 73.22%, showing a significant improvement compared with July [12]. 3.2. Futures and Spot Market No specific analysis content provided, only some charts are presented, including the basis of Shanghai tin main - continuous contract and the LME tin premium/discount (0 - 3) [19][20]. 3.3. Cost Side - The short - term supply of tin ore was generally tight, and the processing fees remained at a low level [27]. - Some charts are presented, including China's monthly tin ore production, tin ore import volume, tin concentrate price, and tin concentrate processing fee [24][26]. 3.4. Supply Side - Some charts are presented, including domestic refined tin monthly output, domestic recycled tin monthly output, tin output and operating rate in Yunnan and Jiangxi, refined tin export and import profits, domestic refined tin import volume, and Indonesia's refined tin import and export [31][33][36][39]. 3.5. Demand Side - China's semiconductor sales growth rate rebounded slightly, and global semiconductor sales maintained high growth [45]. - Some charts are presented, including domestic computer and smartphone production, production of household appliances such as washing machines, air conditioners, refrigerators, and color TVs, China's photovoltaic cell production and photovoltaic installation cumulative volume, domestic key enterprise tin - plated strip production, PVC monthly output, downstream solder enterprise operating rate, and domestic tin apparent consumption [44][47][49][51][53][55][58]. - Tin consumption in the tinplate field continued to decline because aluminum cans had almost completely replaced tinplate cans in the beverage packaging field. PVC stabilizers were the major consumer of tin compounds, and PVC production increased slightly year - on - year in the first half of the year [56]. 3.6. Supply - Demand Balance - Some charts are presented, including China's social inventory and LME inventory [62].

Report Summary 1) Report Industry Investment Rating - The report suggests a bullish outlook for the tin market in the medium term, advising investors to adopt a long - position strategy [4]. 2) Core Viewpoints - The disruption in the Indonesian tin supply and the slow recovery of overseas tin mines, combined with macro - economic factors, have led to a shortage in the global tin supply, causing tin prices to soar. The supply is expected to remain tight before mid - October, and the tin price may continue to strengthen. The复产 speed of the Burmese tin mines may determine the supply elasticity of tin, and if the Indonesian crackdown exceeds expectations or the Burmese复产 is further delayed, the tin price may break through the previous high [2][4]. 3) Summary by Related Aspects Indonesian Supply - Indonesia, the world's largest tin exporter (accounting for over 25% of global supply), has intensified the global tin supply shortage. The Indonesian president ordered the closure of 1000 illegal tin mines on September 29 and plans to crack down on 80% of illegal mining activities. The illegal mine closure may widen the global tin mine supply gap to over 8000 tons in the fourth quarter. In August, Indonesia's tin ingot exports were 3246.46 tons, a 14.39% month - on - month decrease, and exports are expected to continue to decline significantly [2]. Burmese Supply - The复产 of Burmese tin mines is progressing slowly. In August, China imported only 2091 tons of tin ore from Burma, a 27.72% year - on - year decrease, accounting for only 20% of the total domestic imports. Due to the rainy season, equipment shortages, and explosive controls, the actual output remains low, and the output increase is expected to be realized in November [4]. Domestic Supply - Overseas tin mine supply recovery is slow, and domestic raw material supply is tight. Domestic smelter operating rates are continuously decreasing. Yunnan tin smelters have been on a 45 - day maintenance since August 30, and Jiangxi's refined tin output remains low due to a shortage of scrap and crude tin. Domestic smelter output is expected to recover around mid - October, and the low LME tin inventory cannot be quickly replenished [4]. Macroeconomic Factors - The probability of the Fed cutting interest rates in October is 93%. The weakening US dollar and the expectation of loose liquidity have boosted the overall sentiment of the non - ferrous metals sector [4].

1. Report Industry Investment Rating No information provided. 2. Core Viewpoints - Domestic and international macro - optimistic expectations and partial refining tin capacity maintenance support tin prices. The slow resumption of tin mines in Wa State, Myanmar, and the decline in domestic tin ingot social inventory may cause the Shanghai tin price to fluctuate strongly. It is recommended that investors mainly lay out long positions on dips, paying attention to specific support and pressure levels [3][4]. - For spreads and inventory, due to factors such as the weakening employment supply - demand in the US and the slow resumption of tin mines in Wa State, Myanmar, the basis and monthly spreads of Shanghai tin, as well as the spreads of LME tin contracts, are within a reasonable range, and investors are advised to temporarily wait and see for arbitrage opportunities. The total inventory of refined tin at home and abroad has increased compared with last week [10][11][15]. - In terms of supply, the domestic tin ore supply is expected to be tight, the production of recycled tin in September may decrease month - on - month, the production capacity utilization rate of refined tin has declined, and the import volume of refined tin may decrease month - on - month [21][25][30]. - In terms of demand, the production capacity utilization rate of tin solder may increase month - on - month, the import volume of solder strips may decrease month - on - month while the export volume may increase, and the production, import, and export volumes of tin - plated sheets may all decrease month - on - month. The capacity utilization rate of lead - acid batteries has slightly decreased [36][37][42]. 3. Summary by Directory 3.1 First Part: Spread and Inventory Situation - The basis and monthly spreads of Shanghai tin are negative and within a reasonable range. The (0 - 3) contract spread of LME tin is negative and the (3 - 15) contract spread is positive, both within a reasonable range. The Shanghai - London tin price ratio is between the 50 - 75% quantiles of the past five years. Investors are advised to temporarily wait and see for arbitrage opportunities [10][11]. - The inventory of refined tin in the Shanghai Futures Exchange has decreased compared with last week, the social inventory of tin ingots in China has increased, the inventory of refined tin in the London Metal Exchange has increased, and the total inventory of refined tin at home and abroad has increased [15]. 3.2 Second Part: Mid - upstream Supply Situation - The daily processing fee of domestic tin concentrate is oscillating downward, indicating a tight supply expectation of domestic tin ore [21]. - The second beneficiation plant of the Uis mine in Namibia has been commissioned, and tin mines in Wa State, Myanmar, are resuming production. Alphamin Resources' tin mine in Congo is also resuming production in stages. These factors may lead to an increase in domestic tin ore production and a decrease in imports in September [23]. - The production of recycled tin in China in September may decrease month - on - month [25]. - The production capacity utilization rate of refined tin in Yunnan and China (Jiangxi) has decreased (remained flat). Yunnan Tin will conduct maintenance on smelting equipment, resulting in a decrease in the production of refined tin in China in September and an increase in inventory [29]. - The export volume of Indonesia in September may decrease, which may lead to an increase in the import volume and a decrease in the export volume of refined tin in China in September [32]. 3.3 Third Part: Downstream Demand Situation - The daily processing fee of photovoltaic solder strips has decreased, which may lead to an increase in the production capacity utilization rate and a decrease in the inventory of tin solder in China in September [36]. - The import volume of solder strips in China in September may decrease month - on - month, while the export volume may increase [37]. - The production, import, and export volumes of tin - plated sheets in China in September may all decrease month - on - month [42]. - The production capacity utilization rate of lead - acid batteries in China has slightly decreased compared with last week [45].

Group 1 - The core viewpoint indicates that tin prices are experiencing narrow fluctuations, with the main contract rising by 0.46% to 268,090 yuan per ton, amid slow recovery of tin mines in Myanmar and weak supply-demand fundamentals [1] - The recovery of tin mines in Myanmar is progressing slowly due to seasonal rains, earthquakes, and preparation issues, leading to a delay in actual output expected until the fourth quarter [1] - The operating rate of tin smelting enterprises remains low due to tight raw material supply, with the operating rate in Yunnan and Jiangxi provinces reaching 59.23% as of August 15, showing a slight month-on-month decline [1] Group 2 - Downstream orders for tin continue to decline, with the third quarter being a traditional off-season for consumption, resulting in lower orders in the home appliance sector compared to previous years [2] - The semiconductor market is expected to grow, driven by demand from AI, cloud infrastructure, and advanced consumer electronics, although some sub-segments may continue to shrink [2] - The overall demand for tin in photovoltaic solder remains weak due to a significant drop in orders following a mid-year rush for installations [2]

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - This week, tin prices fluctuated and declined. In terms of supply, the mining licenses in the Wa region of Myanmar have been approved, and preparations are underway, with significant recovery in tin ore supply expected in Q4. However, in the short term, raw material shortages in Yunnan are still severe, and some smelters are preparing for maintenance. In Jiangxi, some recycled tin enterprises have resumed production, but the subsequent output is difficult to increase due to the limited supply of scrap tin. In terms of demand, domestic consumption during the off - season remains poor, and downstream factories are cautious about restocking tin raw materials. Overseas, the demand for tin driven by AI computing power remains strong. In terms of inventory, the social inventory of tin ingots increased slightly this week. Overall, the short - term supply and demand are both weak, and due to the continuous resumption of production in Myanmar, it is expected that tin prices will fluctuate weakly in the short term. The short - term operating range of domestic tin prices is expected to be between 250,000 - 270,000 yuan/ton, and the operating range of LME tin prices is expected to be between 31,000 - 33,000 US dollars/ton [11][12]. 3. Summary According to the Directory 3.1 Week - on - Week Assessment and Strategy Recommendation - **Supply Side**: The mining licenses in the Wa region of Myanmar have been approved, and preparations are underway, with significant recovery in tin ore supply expected in Q4. In Yunnan, raw material shortages are severe, and smelter raw material inventories are generally less than 30 days, with some enterprises preparing for maintenance. In Jiangxi, some recycled tin enterprises have ended maintenance and gradually resumed production, but the supply of scrap tin is limited, and subsequent output growth is difficult [11]. - **Import and Export**: The resumption of tin ore production in Myanmar is slow, and the supply from other regions is limited. China's tin ore imports remain at a low level. In June 2025, China's tin concentrate imports were 11,910 tons, a month - on - month decrease of 11.44% and a year - on - year decrease of 7.08%. From January to June, the total import volume of tin concentrates was 62,130 tons, a year - on - year decrease of 32.41% [11]. - **Demand Side**: Consumption during the off - season is poor, and downstream factory orders are generally low. After the end of the photovoltaic rush to install, orders for photovoltaic tin bars in East China have declined, and the operating rate of some producers has decreased. The production schedules of home appliance enterprises in July also decreased significantly. In July 2025, the total production schedule of air conditioners, refrigerators, and washing machines was 29.6 million units, a 2.6% decrease compared to the actual production in the same period last year. Orders for consumer electronics and automotive electronics have weak growth, and market sentiment is cautious. The demand for tin in tin - plated sheets and the chemical industry is relatively stable [11]. - **Summary**: Tin supply is at a low level, and demand is also weak. In the short term, supply and demand are both weak, and due to the continuous resumption of production in Myanmar, it is expected that tin prices will fluctuate weakly in the short term. The short - term operating range of domestic tin prices is expected to be between 250,000 - 270,000 yuan/ton, and the operating range of LME tin prices is expected to be between 31,000 - 33,000 US dollars/ton [11][12]. 3.2 Futures and Spot Market - The report provides charts of the basis of Shanghai tin main contract and the LME tin premium (0 - 3), but no specific analysis content is given [18][20]. 3.3 Profit and Inventory - **Profit**: The report provides charts of tin import and export profits, but no specific analysis content is given [24][25]. - **Inventory**: The social inventory of tin ingots in China and the LME inventory charts are provided. As of August 1, 2025, the social inventory of tin ingots in major Chinese markets was 10,661 tons, an increase of 272 tons compared to last Friday [11][27]. 3.4 Cost Side - Tin ore supply is generally tight, and processing fees remain at a low level [33]. 3.5 Supply Side - **Domestic Production**: In May, affected by raw material shortages and low processing fees, the refined tin production was 14,670 tons, a month - on - month decrease of 0.3% and a year - on - year decrease of 8.3% [38]. - **Import and Export**: In May, the import of tin ore and concentrates was 13,448.797 physical tons, a year - on - year increase of 59.83% and a month - on - month increase of 36.38%. From January to May, the cumulative import was 50,200 physical tons, a cumulative year - on - year decrease of 36.51%. The export of unforged non - alloy tin was 1,770 tons, a year - on - year increase of 18.01% and a month - on - month increase of 8.12%. From January to May, the cumulative export was 9,584 tons, a cumulative year - on - year increase of 38.48%. The import of unforged non - alloy tin was 2,076 tons, a year - on - year increase of 226.14% and a month - on - month increase of 84.07%. From January to May, the cumulative import was 9,508 tons, a cumulative year - on - year increase of 30.91% [38][41]. 3.6 Demand Side - **2024 Consumption Structure**: In 2024, consumption showed a steady growth trend, with the increase mainly coming from the recovery of semiconductor consumption and the increase in photovoltaic module production. In China, solder consumption is still dominant, and the increase mainly comes from the production of photovoltaic modules and the recovery of semiconductor consumption. Overseas, the recovery of semiconductor consumption also drove the growth of tin consumption, but overall growth was slower than in China [51]. - **Semiconductor**: The year - on - year growth rate of China's semiconductor sales has slightly rebounded, and global semiconductor sales have maintained high growth [56]. - **Photovoltaic**: In the first four months of 2025, there was a phased rush to install photovoltaic in China, with significant production growth. In June, the component production schedule decreased significantly month - on - month [62]. - **Home Appliances**: According to the latest production schedule report of three major white goods, in July 2025, the total production schedule of air conditioners, refrigerators, and washing machines was 29.6 million units, a 2.6% decrease compared to the actual production in the same period last year [70].

Group 1 - LME inventory has decreased significantly from approximately 4,800 tons at the beginning of the year to 1,690 tons, representing a cumulative reduction of 65%, reaching a near two-year low [1] - The low inventory levels have increased the risk of short selling in LME tin, with a major holder owning 50-79% of the warehouse receipts, and concentrated long positions in the near term [1] - The LME 0-3 spot premium has expanded significantly, leading to a substantial increase in night trading for LME tin, which in turn has driven up domestic tin prices [1] Group 2 - China's tin ingot imports saw a slight decline in June, while exports increased, with the overall import level expected to decrease due to a persistently closed import window and low profit margins [2] - The domestic supply of refined tin is under pressure, with expectations of substantial outflows of tin ore in Q4 due to the reopening of mining operations in Myanmar [2] - The consumption side is facing challenges, particularly in the photovoltaic sector, which is suppressing solder demand, and the electronics and automotive electronics sectors are entering a seasonal downturn, leading to weak order growth [2]

Group 1 - The core viewpoint indicates that the tin market is experiencing weak demand and supply, leading to a fluctuating price trend. The current price of tin is reported at 261,920 yuan/ton, with a decrease of 0.59% [1] - Recent discussions at the Wa State conference have led to expectations of a slight recovery in tin ore supply, although the overall demand remains weak due to the off-season [1] - The resumption of mining operations in Myanmar's Wa State is limited by rising licensing fees, but some operators have obtained three-year mining licenses, which may lead to a gradual increase in shipments in the coming months [1][2] Group 2 - The smelting plants are currently holding a bullish price sentiment, while traders are cautiously entering the market, primarily focusing on essential purchases [2] - The traditional off-season for downstream demand is impacting order levels, with a decline in actual monthly demand due to reduced production in home appliances and the conclusion of solar energy installations [2] - The market is experiencing a "high inventory, low turnover" situation, with some companies forced to cut production due to insufficient scrap supply and declining processing fees, which are increasing production costs [1][2]

Report Industry Investment Rating No relevant content provided. Core Viewpoints - In June, tin prices fluctuated at high levels. The slow resumption of tin mines in Wa State, Myanmar, and transportation disruptions of tin mines in southern Myanmar via Thailand are expected to reduce China's tin ore imports by 500 - 1000 tons in June, intensifying the short - term supply shortage. In the smelting sector, raw material inventories in major production areas such as Yunnan and Jiangxi are generally less than 30 days, and some smelting enterprises have started maintenance or gradient production cuts, further tightening refined tin supply. [11][12] - After the end of the photovoltaic rush to install, orders for photovoltaic tin bars in East China declined, and the operating rates of some producers decreased. Orders in the consumer electronics and automotive electronics sectors grew weakly, and market sentiment was wait - and - see. Demand for tin in areas such as tinplate and chemicals was stable. As of June 27, 2025, the social inventory of tin ingots in major domestic markets was 9266 tons, an increase of 361 tons from the previous week. [11][12] - Overall, the short - term supply shortage of tin ore is obvious, and upstream enterprises have a strong sentiment of holding back sales. However, terminal demand is weak, and the acceptance of high - priced raw materials is limited. The upstream and downstream of the industrial chain are in a stalemate. It is expected that domestic tin prices will fluctuate in the range of 250,000 - 280,000 yuan/ton in the short term, and LME tin prices will fluctuate in the range of 31,000 - 34,000 US dollars/ton. [11][12] Summary by Directory 1. Monthly Assessment and Strategy Recommendation - **Supply Side**: The slow resumption of tin mines in Wa State, Myanmar, and transportation disruptions via Thailand are expected to reduce June tin ore imports by 500 - 1000 tons. Raw material inventories in major smelting areas are low, and some enterprises have cut production. The combined operating rate of refined tin smelting enterprises in Yunnan and Jiangxi is only 46.84%. [11] - **Imports and Exports**: In May, tin ore and concentrate imports were 13,448.797 physical tons, a year - on - year increase of 59.83% and a month - on - month increase of 36.38%. From January to May, cumulative imports were 50,200 physical tons, a cumulative year - on - year decrease of 36.51%. Unwrought non - alloy tin exports were 1770 tons, a year - on - year increase of 18.01% and a month - on - month increase of 8.12%. From January to May, cumulative exports were 9584 tons, a cumulative year - on - year increase of 38.48%. Unwrought non - alloy tin imports were 2076 tons, a year - on - year increase of 226.14% and a month - on - month increase of 84.07%. From January to May, cumulative imports were 9508 tons, a cumulative year - on - year increase of 30.91%. [11] - **Demand Side**: After the end of the photovoltaic rush to install, orders for photovoltaic tin bars in East China declined. Orders in consumer electronics and automotive electronics grew weakly, while demand in tinplate and chemicals was stable. In June, the production schedule for household air conditioners was 20.5 million units, an 11.5% increase from the previous year; the refrigerator production schedule was 7.9 million units, a 3.6% increase; and the washing machine production schedule was 6.75 million units, the same as the previous year. [11] - **Conclusion**: Tin prices are expected to fluctuate in the range of 250,000 - 280,000 yuan/ton domestically and 31,000 - 34,000 US dollars/ton on the LME in the short term. [11] 2.

Unwrought non - alloy tin imports were 2076 tons, a year - on - year increase of 226.14% and a month - on - month increase of 84.07%. From January to May, cumulative imports were 9508 tons, a cumulative year - on - year increase of 30.91%. [42] 6. Demand Side - **Consumption Structure**: In 2024, consumption showed a steady growth trend, with the increase mainly coming from the recovery of semiconductor consumption and the rise in photovoltaic module production. In China, solder consumption dominated, and the increase was mainly from photovoltaic module production and semiconductor consumption recovery. Overseas, semiconductor consumption recovery also drove tin consumption growth, but overall growth was slower than in China, showing an internal - strong - external - weak trend. [50] - **Semiconductor**: China's semiconductor sales year - on - year growth rate rebounded slightly, and global semiconductor sales maintained high growth. [55] - **Photovoltaic**: In the first four months of 2025, there was a phased rush to install photovoltaic in China, with obvious production growth. In June, the component production schedule decreased significantly month - on - month. [61] - **White Goods**: According to the latest production schedule report of three major white goods, the total production schedule of air conditioners, refrigerators, and washing machines in July 2025 was 29.6 million units, a 2.6% decrease from the previous year.

Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. Core View of the Report The Shanghai Tin main contract 2507 showed a weak oscillating trend today. Despite a slight price increase, the decrease in trading volume and open interest, along with the outflow of funds, indicate that market trading is becoming lighter and short - selling power is strengthening. It is expected that the Shanghai Tin main contract 2507 will continue to maintain an oscillating pattern [11]. 3. Summary by Relevant Catalogs 1. Market Overview and Market Review - **1.1 Daily Market Overall Performance** - The Shanghai Tin main contract 2507 showed a weak oscillating trend on June 25, 2025. The opening price was 263,200 yuan/ton, the highest was 263,800 yuan/ton, the lowest was 261,900 yuan/ton, and the closing price was 263,800 yuan/ton, with a settlement price of 262,150 yuan/ton. The contract price tried to rise in the afternoon but failed to break through the resistance level of 264,000 yuan/ton and then gradually declined. The trading volume was 54,700 lots, a decrease from the previous trading day, indicating a slight decline in market trading activity. The open interest at the close was 13,100 lots [2]. - **1.2 Futures Market Data** - The latest price of the Shanghai Tin main contract (snm) was 263,000 yuan, with a decrease of 190 yuan and a decline rate of 0.07%. Other contracts such as the Shanghai Tin weighted (sni), Shanghai Tin 2512 (sn2512), etc., also had different price changes [6]. 2. Analysis of Influencing Factors - **2.1 Macroeconomic Policy** - The cease - fire agreement between Israel and Iran came into effect, reducing market risk - aversion sentiment and improving risk preference, which provided some support for commodity prices including tin [8]. - **2.2 Tracking and Interpretation of Related Data** - **Supply Side**: Tin ore supply in production areas such as Yunnan is tightening. Some smelting enterprises are considering shutdown for maintenance or slight production cuts in June. The resumption of tin mines in Myanmar's Wa State is slow, and the transportation of tin mines from southern Myanmar through Thailand is blocked. It is expected that the domestic tin ore imports in June will decrease by 500 - 1,000 tons, and the short - term supply shortage of domestic tin ore is obvious, which supports the tin price [9]. - **Demand Side**: Terminal enterprises have entered the seasonal off - season. Orders for consumer electronics and automotive electronics are growing weakly, and the photovoltaic production schedule in June is declining month - on - month. As the tin price rebounds to around 260,000 yuan/ton, the downstream purchasing willingness has significantly weakened, generally adopting a "small - batch, multi - batch" purchasing strategy, which restrains the rise of tin price [10].

Group 1 - The core viewpoint indicates that the tin market is experiencing a tight supply situation due to slow recovery in Myanmar's tin mines, leading to a significant increase in tin prices, which reached a nearly one-month high with a rise of 1.95% to 267,270 yuan/ton [1] - Domestic tin concentrate processing fees have dropped to historical lows, nearing the cost line for smelting enterprises, resulting in squeezed profit margins and prompting some companies to reduce production or undergo maintenance [1] - The downstream electronics industry is entering a low season, and with current high tin prices, there is a prevailing wait-and-see sentiment among end-users, contributing to weak consumption during the off-peak season [1] Group 2 - In May, China's tin ore imports increased month-on-month, with significant contributions from Africa, although the actual output from Myanmar remains low due to slow recovery, with only a few dozen tons exported from Wa State [1] - The import window for tin ingots opened briefly in late April to early May but began to close after mid-May, with some traders relying on previously locked-in prices for shipments [2] - The market outlook suggests that while supply constraints exist due to raw material shortages in Yunnan and reduced scrap tin recovery in Jiangxi, the demand side is showing significant reductions, leading to expectations of a slight oversupply and pressure on tin prices [2]
