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].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - This week, tin prices fluctuated strongly. In terms of supply, the resumption of tin mines in Wa State, Myanmar, is progressing steadily, with the expectation of increased production in the third and fourth quarters. However, short - term smelters in China still face raw material supply pressure, and processing fees are at historical lows. The combined operating rate of refined tin smelting enterprises in Yunnan and Jiangxi provinces is still at a low level. In terms of demand, domestic off - season consumption remains poor, with overall weak orders from downstream factories and cautious restocking of tin raw materials. In June, the operating rate of domestic sample tin solder enterprises declined significantly compared to May, while overseas demand for tin continues to be strong driven by AI computing power. In terms of inventory, the social inventory of tin ingots decreased slightly this week. As of July 18, 2025, the social inventory of tin ingots in major domestic markets was 10,096 tons, an increase of 311 tons from last Friday. Overall, the tin supply is at a low level, and the demand side is also weak. In the short term, both supply and demand are weak. Due to the strengthened expectation of Myanmar's resumption of production, it is expected that tin prices will fluctuate weakly in the short term [11][12]. 3. Summary by Directory 3.1 Week - on - Week Assessment and Strategy Recommendation - **Supply**: The resumption of tin mines in Wa State, Myanmar, is progressing. A resumption meeting was held this week, and some mining license applications were approved. Tin ore production is expected to be gradually released in the third and fourth quarters. However, short - term domestic smelters still face raw material supply pressure, processing fees are at historical lows, and the operating rates of smelters in Yunnan and Jiangxi provinces remain low [11]. - **Imports and Exports**: In May, 13,448.797 physical tons of tin ore and concentrates were imported, a year - on - year increase of 59.83% and a month - on - month increase of 36.38%. From January to May, a total of 50,200 physical tons were imported, a cumulative year - on - year decrease of 36.51%. 1,770 tons of unforged non - alloy tin were exported, a year - on - year increase of 18.01% and a month - on - month increase of 8.12%. From January to May, a total of 9,584 tons were exported, a cumulative year - on - year increase of 38.48%. 2,076 tons of unforged non - alloy tin were imported, a year - on - year increase of 226.14% and a month - on - month increase of 84.07%. From January to May, a total of 9,508 tons were imported, a cumulative year - on - year increase of 30.91% [11]. - **Demand**: Off - season consumption is poor, with weak overall orders from downstream factories and cautious restocking of tin raw materials. After the end of the photovoltaic rush to install, orders for photovoltaic tin bars in East China have declined, and the operating rates of some producers have decreased. The production schedules of home appliance enterprises in July have also declined 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 performance of the same period last year. Orders for consumer electronics and automotive electronics are growing weakly, and the market is waiting and watching. The demand for tin in the tin - plating and chemical industries is relatively stable [11]. - **Conclusion**: Tin prices are expected to fluctuate weakly in the short term due to the strengthened expectation of Myanmar's resumption of production, despite the current low - level supply and weak demand [11][12]. 3.2 Spot and Futures Market - The report presents the charts of the basis of Shanghai Tin main - contract and the LME tin premium (0 - 3), but no specific analysis content is provided [19][20]. 3.3 Profit and Inventory - **Profit**: The report shows the charts of tin export and import profits, but no specific analysis content is provided [25][26]. - **Inventory**: The report shows the charts of China's social inventory and LME inventory, but no specific analysis content is provided [28]. 3.4 Cost Side - Tin ore supply is generally tight, and processing fees remain low [33]. 3.5 Supply Side - **Tin Ore Imports**: In May, 13,448.797 physical tons of tin ore and concentrates were imported, a year - on - year increase of 59.83% and a month - on - month increase of 36.38%. From January to May, a total of 50,200 physical tons were imported, a cumulative year - on - year decrease of 36.51% [11]. - **Refined Tin Production**: Affected by the shortage of raw materials and low processing fees, the domestic refined tin production in May was 14,670 tons, a month - on - month decrease of 0.3% and a year - on - year decrease of 8.3% [38]. - **Imports and Exports of Unforged Non - Alloy Tin**: In May, 1,770 tons of unforged non - alloy tin were exported, a year - on - year increase of 18.01% and a month - on - month increase of 8.12%.

1. Report Industry Investment Rating - No information provided regarding the report industry investment rating. 2. Core View of the Report - The report anticipates that the price of tin will fluctuate with a bias towards strength. Tin ore supply remains tight, though long - term supply recovery is clear. Demand is mixed, with some sectors like photovoltaic showing weakness, while new energy vehicle consumption is strong. [5][36] 3. Summary by Relevant Catalogs 3.1 Report Summary - US initial jobless claims decreased, and continuing claims reached the highest level in years. The US Q3 GDP had a quarterly contraction greater than expected, and consumer spending also declined. The conflict between Israel and Iran eased, reducing supply concerns. Market confidence in economic growth was insufficient, and the metal index fell. Tin ore supply remained tight, and the复产 rhythm of Burmese mines might slow. Supply recovery was clear in the long - term but uncertain in the short - term. On the demand side, photovoltaic tin strip orders declined, and overall demand was lackluster. [5] 3.2 Multi - Empty Focus - **Bullish Factors**: Tin ore and scrap supply remained tight, inventory decreased, and the US dollar index dropped significantly.

From January - April 2025, production was 119,400 tons, consumption was 111,700 tons, with a supply surplus of 7,700 tons. In April 2025, global tin ore production was 27,600 tons, and from January - April, it was 103,700 tons. [9] - **Price and Basis**: This week, tin futures prices strengthened. The basis of Shanghai tin was 1,340 yuan/ton, and the premium increased. The LME tin premium was 96 US dollars/ton, and the discount strengthened. [12] - **Smelter Operating Rate**: As of last Friday, the combined operating rate of refined tin smelters in Yunnan and Jiangxi dropped to 47.05%. Yunnan had some plants for maintenance and reduction, and Jiangxi's rate declined significantly, about 35 percentage points lower than at the beginning of the year. Future operating rates might remain low or decline. [15] - **Import Data**: In May 2025, China's tin ore imports were 13,400 tons (about 6,518 metal tons), a 36.39% month - on - month and 59.84% year - on - year increase. From January - May, cumulative imports were 50,200 tons, a 36.51% year - on - year decrease. The increase in May was mainly due to Africa. [18] - **Production Data**: In May 2025, domestic refined tin production was 14,670 tons, a 0.3% month - on - month and 8.34% year - on - year decrease. From January - May, cumulative production was 72,900 tons, a 0.75% year - on - year decrease. In June, production is expected to be around 13,800 tons.

Large and medium - sized solder plants had an upward trend, while small ones were weak. [30] - **Inventory Data**: The latest LME tin inventory was 2,115 tons, the lowest in two years. As of the week of June 20, Shanghai tin inventory decreased by 1.99% to 6,965 tons, the lowest in three months. [34] 3.4后市研判 - The price of tin is expected to fluctuate with a bias towards strength. [36]

Core Viewpoint - The tin market is experiencing downward pressure on prices due to seasonal demand weakness and the resumption of tin mining in Myanmar, leading to a significant price drop at the end of May [1][2]. Supply Side Analysis - The supply side remains a key focus, with rumors of resumed tin mining in Myanmar's Wa region contributing to price declines. The International Tin Association reported that production in Wa has fully resumed since late April, with the first batch receiving export permits by the end of May [2][3]. - China's tin concentrate imports hit a near-record low in April, with the Democratic Republic of Congo surpassing Myanmar as the largest source of imports. The recovery of Myanmar's production is expected to take time to reach historical capacity levels [2][3]. - As of the end of May, processing fees for tin concentrate in Yunnan and Jiangxi have dropped to their lowest levels in five years, indicating tightening supply affecting smelting profits. The overall refined tin supply may tighten due to reduced imports and ongoing inventory consumption [2][3]. Demand Side Analysis - Despite some resilience in demand, the overall performance is mixed. The photovoltaic sector shows growth, while the semiconductor industry has seen production increases but faces weakening in end-product demand [3][4]. - The PVC sector is operating at high rates but is experiencing significant losses, and the real estate market remains sluggish, impacting demand for PVC and related products [3][4]. - Domestic tin social inventory continues to decline and is at historically low levels, with increased replenishment willingness observed as prices drop significantly [3][4]. Market Outlook - The outlook for June indicates that while short-term price stabilization may occur, uncertainties regarding tariffs and the anticipated recovery in supply, coupled with marginal demand declines, will likely exert downward pressure on tin prices [2][4].

Core Viewpoint - Tin prices have rebounded due to market corrections after a significant decline, despite ongoing supply constraints and uncertain recovery from Myanmar's tin mines [1][2] Group 1: Supply Dynamics - Tin prices rose by 3.14%, closing at 257,940 yuan/ton, influenced by expectations of supply recovery from Myanmar, although these expectations remain unconfirmed [1] - Domestic supply of tin concentrate processing fees (TC) remains at historical lows, nearing smelter cost lines, which severely squeezes profit margins [1] - In May, China's refined tin production decreased by 2.37% month-on-month and 11.24% year-on-year, indicating a tightening supply chain [1] Group 2: Production and Capacity - The overall operating rate of domestic smelters has slightly declined due to ongoing supply chain constraints, with some smelting enterprises in Yunnan and Jiangxi planning maintenance shutdowns in June [1] - The tightening of tin concentrate and scrap supply continues to impose rigid constraints on production capacity [1] Group 3: Demand Trends - Demand remains stable, but future expectations are weak, with consumption growth in the tin end market driven by national policy support and product upgrades in the first four months of the year [1] - After a policy retreat in May, the photovoltaic market's consumption began to face pressure, while mid-year promotional activities are expected to boost demand in consumer electronics and new energy vehicles [1] - However, entering the traditional off-season in July and August, combined with high finished product inventories, may slow down the growth rate of tin terminal consumption [1] Group 4: Market Sentiment - Recent price declines have improved market sentiment for stocking up, although end customers maintain a cautious approach with general order situations [1] - Newhu Futures commented that while supply expectations have not yet materialized, the current situation remains tight, and low operating rates at smelters persist [2] - Domestic inventory has significantly decreased, while overseas stocks remain low, providing some short-term support for prices [2]
