[SMM Analysis: Raw Material Supply Continues to Decline, Operating Rates of Smelters in Yunnan and Jiangxi Continue to Slide]: According to processing data from SMM's in-depth market survey, as of Friday this week, the operating rates of refined tin smelters in Yunnan and Jiangxi, two major tin-producing provinces, have declined to relatively low levels, with a combined operating rate of 47.05%. The operating rate of smelters in Yunnan remained unchanged from the previous week. Some smelters have halted production for maintenance, while others have begun to implement phased production cuts to address the current shortage of raw material supply. During the same period, the operating rate of smelters in Jiangxi dropped significantly, remaining consistently lower than that in Yunnan and declining by approximately 35 percentage points compared to the beginning of the year. Several smelters began halting production for maintenance this month to alleviate the tight supply of scrap. The rising cost of scrap recycling, coupled with the decline in tin concentrate TCs, has driven up production costs for enterprises, eroding the profits of secondary tin smelting. Meanwhile, considering the stalled production resumptions in the Wa region of Myanmar, combined with the impact of the rainy season on transportation, tin ore imports from the Wa region are expected to continue declining this month. Additionally, due to transportation bans imposed by relevant Thai authorities in southern Myanmar, tin ore supply will be reduced by 500-1,000 mt (metal content). In summary, given the decline in the supply of tin ore and scrap, smelters in Yunnan and Jiangxi are likely to maintain low operating levels or continue to experience a downward trend in the coming weeks.

[SMM Tin Midday Review: Some Smelters Have Initiated Maintenance or Gradual Production Cuts; SHFE Tin Prices May Fluctuate Considerably in the Afternoon] Tight Supply of Tin Ore: The ban on transporting tin ore from southern Myanmar via Thailand continues to escalate, with domestic tin ore imports in June expected to decrease by 500-1,000 mt (metal content), exacerbating pressure on the raw material side. Due to insufficient raw material inventory (generally below 30 days) and low TCs, smelters in major production areas such as Yunnan and Jiangxi have maintained low operating rates (approximately 54% in total), with some enterprises having initiated maintenance or gradual production cuts.

[SMM SHFE Tin Brief Review: Sluggish Growth in Orders for Consumer Electronics and Automotive Electronics, Significant Weakening of Purchase Willingness Among Downstream Enterprises] Today, the most-traded SHFE tin contract (SN2507) fluctuated rangebound, opening at 265,100 yuan/mt and closing at 265,150 yuan/mt, with a trading volume of 13.505 billion yuan. Market trading was sluggish, and open interest decreased to 25,600 lots, reflecting the ongoing tug-of-war between bulls and bears near the 265,000 yuan/mt threshold, with a lack of clear direction in the short term.​​Tightening Raw Material Supply​​: The pace of production resumptions at tin mines in Myanmar's Wa region remains uncertain. Additionally, Thailand has suspended the transit of tin ore from Myanmar through its territory since June 4, which is expected to reduce domestic tin ore imports by 500-1,000 mt in June. Affected by the shortage of raw materials and the rainy season, waste tin recycling in Yunnan and Jiangxi, the two major producing regions, has been impacted. As a result, smelters' operating rates have remained low, and the supply of refined tin has continued to tighten.

[SMM Tin Market Brief: Industry orders in downstream sectors such as electronic solder are suppressed by high prices, compounded by the traditional consumption sector entering the off-season]​​​​Tin ore imports restricted​​: Due to the suspension of transportation routes in southern Myanmar by Thailand (starting from June 4) and internal transportation disruptions in Myanmar, China's tin ore imports in June are expected to decrease by 500-1,000 mt (metal content). Additionally, the production resumption in Wa State, Myanmar, is progressing slowly, with the restoration of the power system requiring at least three months, making it difficult to change the tight supply situation of ore in the short term.​​​​Weak traditional demand​​: Industry orders in downstream sectors such as electronic solder and tinplate are suppressed by high prices, with some companies' operating rates falling below 60%.......

[SMM Analysis: Operating Rates of Smelters in Yunnan and Jiangxi Continue to Decline, with Supply from Myanmar Continuing to Shrink]: According to SMM's processing data obtained through in-depth market surveys, as of Friday this week, the operating rates of refined tin smelters in Yunnan and Jiangxi, two major tin-producing provinces, remained at a low level, with a combined operating rate of 53.86%. The operating rate of smelters in Yunnan continued to decline compared to the previous week and was nearly 10 percentage points lower than at the beginning of the year. The treatment charges (TCs) for tin concentrates with a 40% grade remained at historically low levels, approaching the cost line of smelters and severely squeezing profit margins. Some smelters have halted production for maintenance, while others have begun to implement phased production cuts to address the current shortage of raw material supply. During the same period, the operating rate of smelters in Jiangxi was only 40.19%, consistently lower than that in Yunnan and down by approximately 15 percentage points compared to the beginning of the year. Some enterprises have been forced to implement long-term production cuts due to insufficient scrap supply, with some capacities potentially exiting the market permanently. The reduction in scrap sources and the dual squeeze on costs have led to an increase in scrap recycling costs combined with a decline in tin concentrate TCs, driving up production costs for enterprises and undermining the profitability of refined tin recycling from scrap. According to sources, relevant Thai authorities have decided to suspend the transportation of tin ore from Myanmar to Thailand starting from June 4. SMM understands that approximately 500-1,000 mt (metal content) of tin ore is transported from southern Myanmar to Thailand each month for transit into China. The Thai authorities' ban is expected to affect the transportation of tin ore from southern Myanmar in June.

At the 2025 Indonesia Mining Conference & Critical Metals Conference - Tin Session , Chen Peng, Senior Tin Analyst at SMM, discussed the theme of changes in the global tin industry chain landscape and future development trends. 1. Global Tin Resource Distribution and Supply Landscape Intensified Resource Scarcity: Static Mining Lifespan Less Than 15 Years China accounts for 22% of global tin ore reserves but contributes 45% of global production, with resource development intensity exceeding critical thresholds. • Global tin resources are highly concentrated, with China, Indonesia, and Myanmar collectively accounting for over 50%. China, as the largest producer (45% of production), and Indonesia form a dual-core driving force, yet with significant differences in resource endowments. Tin Ore Segment: Global tin ore production is also primarily concentrated in countries with high reserves • Global tin ore production is mainly concentrated in countries such as China, Indonesia, Myanmar, and the DRC. • Except during the COVID-19 pandemic period, global tin ore production has consistently remained at the level of 300,000 mt in metal content annually. Tin Ore Segment: Tin ore imports continued to decline in 2025, with cumulative YoY imports for January-April 2025 at -47.98%. The contraction of tin ore supply from Myanmar has become a long-term trend. • The market generally expects that Wa State may resume production by mid-2025, but the initial increase will not exceed 10,000 mt in metal content, and it will require a 2-3 month transmission period. The progress of production resumption will be constrained by Sino-Myanmar mining trade negotiations and the centralization process in Wa State. Tin Ore Segment: Myanmar's Dominance Weakens, Diversified Landscape Accelerates • Before 2023: Myanmar once accounted for 72%-85% of China's tin ore imports. However, after the implementation of the mining ban policy in Wa State in August 2023, its supply volume plummeted. By 2024, Myanmar's import share dropped to 48.1%, and further declined to 24%-30% in 2025. The core mining area, Mansang (accounting for 80% of Myanmar's supply), remains in a state of suspension. • Emergence of Alternative Sources: Imports from Africa (DRC, Nigeria), South America (Peru, Bolivia), and Australia have increased significantly. For example, in 2025, the import share from the DRC rose to 28%, Nigeria's import share reached 11%, and Australia's imports surged by 101% YoY. The 20-day moving average of recent tin ore import profit margins has remained stable. ►Risk Point Reminder: African Supply Chain Stability to Be Verified: Operational risks at Alphamin mine in the DRC (short-term suspension in April 2025). Global Refined Tin Landscape Features "Asia-Dominated, South America-Supported, Africa-Supplemented" • In the global tin industry chain, most smelting and refining activities are concentrated near tin ore production sites. Countries such as China, Indonesia, Malaysia, Peru, Thailand, the DRC, Bolivia, and Brazil all have smelters of a certain scale, with China and Indonesia accounting for a relatively high proportion. The production resumption process in the Wa region of Myanmar has commenced, but due to the impact of earthquakes and rising policy implementation costs, the actual increase may fall short of expectations. The core contradiction in the tin ore event chain in the DRC lies in the game between geopolitical conflicts and resource dependence. Risk Points: Stability of the African supply chain to be verified: As the largest importer, China's refined tin industry chain is significantly affected by disruptions in the DRC, while the growth in demand for AI, new energy, etc., further exacerbates the supply-demand imbalance. 2. Global Tin Consumption Structure and Demand Evolution Terminal Segment: Tin Consumption Structure • In the global tin consumption structure, tin solder accounts for 48%, tin chemicals 16%, lead-acid batteries 7%, and tin alloys 7%. • In China's tin consumption structure, tin solder accounts for 67%, tin chemicals 12%, lead-acid batteries 7%, and tinplate 6%. Terminal Segment: The Philadelphia Semiconductor Index (SOX) shows a significant negative correlation with the real yield of 10-year US Treasuries. AI demand has driven the capacity utilisation rate of semiconductor companies to record highs. • In the past two years, the SOX has shown a significant negative correlation with the real yield of 10-year US Treasuries, primarily driven by liquidity expectations and valuation pressures. • In 2024, the capacity utilisation rate of the US computer and semiconductor industry remained stable at 76.53%-78.44%, close to the average over the past 10 years (76.72%). In specific segments, the semiconductor capacity utilisation rate reached 95% in Q1 2025, a record high, reflecting the supply-demand tension driven by AI demand. Terminal Segment: The cumulative YoY growth rate of PVC resin production has dropped back slightly, while key enterprises producing tinplate have operated smoothly throughout the year. • The construction of commercial housing is not an isolated process; it is usually accompanied by an increase in demand for building materials. Despite two consecutive years of decline in the sales area of commercial housing, completion demand and policy support (such as ensuring timely delivery of housing projects and infrastructure investment) have driven PVC consumption growth, with a "weak positive correlation" maintained between the two in the past two years. • In the past two years, the tinplate industry has exhibited a differentiated pattern of "shortage in the high-end segment and surplus in the low-end segment". Leading enterprises have consolidated their advantages through technological upgrades and export markets, while small and medium-sized enterprises face integration pressures. However, overall production has remained at a relatively stable level and is expected to maintain its current magnitude in the future. 3. Inventory Cycle and Supply Chain Resilience Building Inventory Link: China's tin ingot social inventory exhibits significant cyclical characteristics •From February to March 2025, inventory showed an alternating pattern of "increase-decrease", mainly due to the release of downstream restocking demand coupled with fluctuations in SHFE tin prices. •Inventory changes in tin ingots are highly correlated with prices, seasonal demand (e.g., the "September-October peak season"), and policy adjustments (e.g., production restrictions in smelting), exhibiting a cyclical pattern of "inventory buildup in H1 and destocking in H2". It also elaborated on the inventory levels within China's tin industry chain. 4. Changes in the Global Tin Industry Chain Landscape and Future Development Trends In 2024, the global tin market was characterized by "regional shortages and a slight global deficit" The tin market achieved a tight balance amid supply disruptions and demand differentiation in 2024, and is expected to shift towards a slight surplus in 2025. However, structural contradictions (uneven regional supply recovery, emerging demand growth) will dominate price fluctuations. The market should closely monitor the pace of production resumptions in Myanmar, Indonesia's exports, and the semiconductor industry's recovery, while guarding against unexpected shocks from macro policies and geopolitical risks. ►SMM Outlook •In 2024, the global tin ingot market was characterized by concurrent supply contraction and weak demand recovery. Affected by factors such as the suspension of mining operations in Myanmar's Wa region and delayed approval of Indonesia's export quotas, global tin ore production declined YoY. However, the release of unreported inventory and the supplementation of recycled tin alleviated supply pressures, leading to a slight increase in annual refined tin production to approximately 374,000 mt. On the demand side, weak recovery in the semiconductor industry and a slowdown in PV growth dragged down global consumption to around 373,000 mt, resulting in a supply-demand gap of approximately 11,000 mt. •In 2025, expectations for production resumptions in Myanmar (with potential output increases in H2) and full production at new projects in the DRC and China will drive supply growth. On the demand side, the upward trend in the semiconductor cycle, coupled with the application of AI technology and growth in NEVs, may increase global consumption to 375,000 mt. However, growth in traditional sectors (e.g., tinplate, home appliance exports) will slow down to 2.1%-3.5% due to trade frictions. The annual supply-demand gap may narrow to 5,100 mt, but geopolitical risks (Myanmar's political situation, Indonesia's exports) may exacerbate volatility. 》Click to view the special report on the 2025 Indonesia Mining Conference & Critical Metals Conference

At the beginning of April, SHFE tin prices fell sharply under pressure due to the escalation of trade conflicts. However, as tariffs were suspended, tin prices rebounded, recovering previous losses and returning to levels before the supply disruptions of tin ore in the DRC. Nevertheless, the market reacted strongly to rumors last week about production resumptions and fee payments in the Wa region, causing tin prices to break through support levels and continue to weaken at the beginning of this week, with the most-traded contract falling below the 250,000 mt threshold. Currently, these market rumors remain unverified. According to SMM, few enterprises are paying fees to obtain mining licenses, with many adopting a wait-and-see attitude, and most major mining traders have not paid management fees. Moreover, the current inspections at the China-Myanmar border are stringent, and the entry procedures for most large-scale equipment and relevant mining personnel are complex. Therefore, the current pace of production resumptions in the Wa region may fall short of market expectations. So, does the current tin price still have the momentum to continue declining? Tight Actual Supply of Tin Ore, with Increasing Expectations for Future Increases In recent years, speculation on SHFE tin has mainly revolved around supply, as tin is a relatively scarce metal with limited content in the Earth's crust and a high degree of supply concentration, primarily distributed in China, Indonesia, Myanmar, Australia, and other regions. After Myanmar suspended tin ore mining on August 1, 2023, global tin resources have been in a relatively tight supply situation. Consequently, the market is highly sensitive to supply-side information, with any slight changes triggering significant market fluctuations. In the early stages of Myanmar's mining ban, China's tin ore imports remained at a relatively high level due to the availability of ore inventory for export. However, as inventory was depleted, China's tin ore imports plummeted from Q2 last year, and the issue of tight domestic tin ore supply has become increasingly prominent. During this period, Chinese enterprises actively sought alternative resources from other countries. However, due to limited global new tin ore discoveries in recent years, the tight resource situation has not been alleviated. Among them, the Bisie mine, owned by Alphamin in the DRC, is the largest mine in Africa and the third largest globally. The mine has two projects: the Mpama North project operates steadily, while the Mpama South project commenced production on May 17 last year, making it the largest among the newly commissioned projects last year. Tin ore from the DRC has also become an important source of tin ore imports for China, currently accounting for about 30%. Production at the Alphamin mine was suspended for over a month in March due to local armed conflicts but gradually resumed in early April. The production interruption at the Alphamin mine, which only recovered about 1,290 mt of tin metal, may result in a supply gap of approximately 2,000-3,000 mt. Currently, Alphamin has revised its tin production guidance for the 2025 fiscal year downward from 20,000 mt to 17,500 mt. Since the beginning of this year, the resumption of tin ore production in Myanmar has gradually been put on the agenda. On February 26, the Wa State Industrial and Mineral Resources Administration issued the document "Procedures for Applying for Mining, Beneficiation Plant, and Prospecting Licenses," which explicitly stipulated the process for applying for licenses in mining areas. On the morning of April 23, 2025, the Wa State Industrial and Mineral Resources Administration held a special symposium on the resumption of production at the Mansang mine. The meeting announced relevant documents and clarified the work procedures. However, after the symposium, the authorities had not yet issued a clear signal for a full resumption of production. On May 27, market news emerged that the first batch of tin ore from Myanmar's Wa State had reportedly obtained export licenses, but the authenticity of the rumors was questionable. Even if production resumption were confirmed, the first batch of tin ore would not enter the market until at least the end of June. Currently, tin ore supply is tight, and domestic tin concentrate treatment charges (TCs) remain at historically low levels. As of May 30, the tin concentrate TC for 40% grade ore in Yunnan was 11,000 yuan/mt, and for 60% grade ore in Jiangxi, Guangxi, and Hunan was also 11,000 yuan/mt, approaching the cost line of smelters and severely squeezing profit margins. The shortage of raw material supply has affected the production of smelters. According to SMM data based on market-adjusted processing figures, in May 2025, China's refined tin production decreased by 2.37% MoM and 11.24% YoY. The continuous tightening of the tin concentrate and scrap tin supply chains has imposed rigid constraints on capacity, leading to a slight decline in the overall operating rate of domestic smelters. As of May 30, the operating rates of refined tin smelters in Yunnan and Jiangxi, two major tin-producing provinces, remained at low levels, with a combined operating rate of 54.58%. Regionally, in Yunnan, the shortage of raw materials and cost pressures are intertwined. Raw material inventories at Yunnan smelters are generally below 30 days, with some enterprises facing inventory backlogs due to high-priced stockpiling in the early period. However, weak downstream demand has made it difficult to sell goods, resulting in sluggish spot premium transactions. Some smelters in core production areas such as Gejiu have entered seasonal maintenance or production cuts due to raw material shortages and cost pressures. In Jiangxi, since the beginning of the year, the local scrap tin recycling volume has consistently been below 70% of the annual average, mainly due to the US imposing high tariffs on Chinese electronics, leading to a contraction in solder export orders and a reduction in scrap sources. Some enterprises have been forced to implement long-term production cuts due to insufficient scrap, with some capacity potentially exiting the market permanently. In Inner Mongolia, production slightly rebounded in May due to production issues at captive mines, but it has not yet returned to previous levels. Production areas such as Anhui have continued to experience operating rates below expectations due to shortages of scrap and tin concentrates. Based on SMM estimates, refined tin production is expected to decrease by 4.58% MoM in June, with some smelters in Yunnan and Jiangxi planning to halt production for maintenance. Overall, tin ore supply in June is unlikely to see significant recovery. However, the period of the tightest global tin supply is about to pass, and the market will enter a verification phase for the improvement of the supply-demand gap. Close attention should be paid to the return of tin ore from Africa and the resumption progress of tin ore production in Myanmar. There is a lack of significant incremental demand in the downstream sector. Global semiconductor sales exhibit cyclical changes. The current semiconductor cycle bottomed out in February 2023, with YoY growth in sales turning positive in November 2023. Since then, the growth rate has been climbing, but it gradually slowed down after October 2024. Currently, the absolute amount of global semiconductor sales remains at a high level. Sales began to pull back slightly from December 2024 and saw a slight MoM rebound in March 2025. This global semiconductor cycle is driven by AI computing power construction, primarily in advanced manufacturing processes. Therefore, the core beneficiaries are concentrated overseas, while domestic capacity is mainly in mature manufacturing processes, offering limited impetus. The downstream semiconductor industries in China are more concentrated in areas such as consumer electronics and automotive. From January to April 2025, domestic mobile phone shipments reached 94.708 million units, up 3.5% YoY. Overall, China's policy subsidies have further boosted market consumption, and the Chinese smartphone industry has shown steady growth from January to April 2025. The recent 618 shopping festival has already kicked off and is expected to support stable end-use consumption electronics. However, the market is expected to gradually enter the off-season for demand in July and August. Enterprises may slow down their stockpiling pace, and it is anticipated that downstream demand for raw materials such as tin will also drop back slightly. Whether there will be an outperformance in demand this year remains to be seen, depending on whether AI blockbuster products emerge in the consumer electronics sector. In recent years, the new demand for tin solder has mainly been reflected in PV solder, currently accounting for over 10%. According to data released by the National Energy Administration, the installed power generation capacity for solar energy from January to April 2025 was 990 million kW, up 47.7% YoY. The significant growth in new PV installed capacity is primarily driven by the installation rush driven by policy timelines. In January 2025, the National Energy Administration issued the "Administrative Measures for the Development and Construction of Distributed PV Power Generation," clarifying that April 30, 2025, is the demarcation point for the implementation of new and old policies. Existing projects that completed their filings before this date will still enjoy the original subsidy and grid connection policies, while new projects will fully implement market-based rules thereafter. On February 9, 2025, the National Development and Reform Commission (NDRC) and the National Energy Administration jointly issued the "Notice on Deepening the Market-Oriented Reform of New Energy On-Grid Tariffs to Promote High-Quality Development of New Energy." Starting from May 31, 2025, incremental distributed PV projects will fully enter the market. All new projects will, in principle, have their entire electricity output traded in the power market, with electricity prices formed through market bidding, and subsidies will completely exit the historical stage. Meanwhile, a "price settlement mechanism for the sustainable development of new energy," namely, a "refund for excess, supplement for shortfall" differential settlement mechanism, has been established to stabilize revenue expectations. To capitalize on the two major policy periods of "430" and "531," downstream enterprises initiated an installation rush, driving a significant YoY increase in domestic newly installed PV capacity in April. However, projects connected to the grid after May 31, 2025, are required to fully comply with the new regulations. It is expected that the growth rate of PV installation capacity will subsequently slow down, which will also drag down the demand for tin. Meanwhile, market consumption in traditional sectors such as tinplate and PVC heat stabilizers remains stable. Downstream enterprises are highly sensitive to price changes. Recently, with the decline in tin prices, market sentiment for stockpiling has improved, and downstream procurement demand has rebounded. However, finished product inventories in some markets remain at relatively high levels, ultimately limiting the boost to raw material procurement by downstream enterprises driven by growth in end-user market demand. Overall, the increase in tin concentrates in June is expected to be relatively limited, so the supply will remain slightly tight in the short term. However, the supply of raw materials is expected to gradually improve, and the market will subsequently enter a verification period for the improvement of the supply-demand gap. Close attention should be paid to the return of tin ore from Africa and the production resumption progress of tin mines in Myanmar. On the demand side, the market is about to enter the off-season, with weak expectations for demand growth, making it difficult to effectively boost tin prices. Therefore, in the short term, under the expectation of increased supply, there may be downward pressure on the central tendency of the market, but constrained by the current situation where the shortage of tin ore has not significantly eased, market trends may fluctuate. However, from a long-term perspective, the AI industry cycle has not yet ended. If there is a surge in demand from AI end-users, it is expected to significantly drive up tin demand. At that time, the growth rate of supply may lag behind the resilience of demand, and the downside room for tin prices in the medium and long term will be limited. Nevertheless, there is still uncertainty in current trade policies, and caution should be exercised against significant disruptions to tin prices caused by macro factors. (Wenhua Comprehensive)

Tin prices have fallen sharply recently. Looking ahead, on the macro front, the US economy is expected to slow down this year, and the US Fed may extend the period of maintaining the current interest rate level. On the supply and demand front, the continuous implementation of trade-in and equipment renewal policies in China is boosting the demand for non-ferrous metals in the manufacturing and consumer sectors. Myanmar's tin ore accounts for approximately 30.38% of China's tin ore imports and 47% of the total domestic tin ore supply. According to customs data, China's tin ore imports in April 2025 were 9,800 mt (equivalent to approximately 4,336 mt (metal content)), up 18.48% MoM and down 4.22% YoY. From January to April, cumulative tin ore imports were 36,700 mt, a significant year-on-year decline of 47.98%. Since Myanmar implemented a ban on tin ore mining in August 2023, China's tin ore imports from Myanmar have remained at a low level due to the uncertainty surrounding the resumption of production. The downward trend in import volumes continued in April 2025, primarily due to unstable import profitability and the impact of the situation in Myanmar's Wa region. The tight supply of tin ore has led to a 40% decline in processing fees. The processing fee for tin concentrates in Yunnan Province dropped from 17,000 yuan/mt from May to July 2024 to 12,000 yuan/mt, which is lower than the 13,550 yuan/mt at the end of March 2023 and close to the cost line of some enterprises, leading to production cuts by some enterprises. Currently, processing fees are hovering near the lowest levels in the past six years. The tight supply of tin ore has been transmitted to the refined tin smelting sector. The shortage of ore sources is directly reflected in production data: in the week ending May 23, the operating rate of refined tin smelters in Yunnan and Jiangxi provinces was 56.44%, down 0.66 percentage points from the previous week, with operating rates in Yunnan and Jiangxi being 65.48% and 41.02%, respectively. In Yunnan, smelters are under sustained profit pressure due to low tin ore imports from Myanmar and depressed processing fees. In Jiangxi, some enterprises are struggling to resume production due to insufficient recycling volume of scrap tin and declining processing fees. In April 2025, China's refined tin production was 15,200 mt, down 0.5% MoM and 8.1% YoY. It is expected that production will increase by approximately 2% MoM in May. In downstream industries, tin solder demand accounts for 68%, with the semiconductor sector accounting for 80% of total tin solder demand. In April 2025, the overall sample operating rate of domestic tin solder enterprises was 76.7%, up 0.9 percentage points from March but below market expectations. It is expected that the operating rate will remain low in May. Currently, orders from traditional downstream industries have not yet surged, with just-in-time procurement being the main focus, and spot market transactions remain sluggish. However, global semiconductor demand provides long-term support for the tin market. Global semiconductor sales increased by 18.8% YoY in Q1 2025, and the market size is expected to grow by 11% YoY for the full year, potentially boosting global tin demand by 4.4%. Additionally, the operating rate of primary lead production in the three provinces rose slightly by 0.4 percentage points to 67.75% last week. Despite the off-season in the battery market limiting further rebounds in the operating rate, production remained at a high level in recent years. The domestic tin market has entered a destocking cycle, but the rate of destocking has slowed. As of the end of last week, SHFE tin inventory stood at 8,445 mt, a decrease of 28 mt from the previous week; LME tin inventory was 2,665 mt, down 70 mt from the prior week. According to SMM data, the total social inventory of tin ingots in the three regions was 10,333 mt on May 27, an increase of 374 mt from the previous week. The tin market is exhibiting a pattern of "constrained supply and promising demand." Conflicts in the DRC and earthquakes in Myanmar have heightened market concerns about the supply side. Coupled with the delay in the production resumptions in Wa State, refined tin production continued to decline YoY. Despite being in the off-season, the growth in demand from the semiconductor industry provides some support to the tin market. From a cost perspective, current prices are approaching the range of the tariff floor and cost floor. SHFE tin below 258,000 yuan/mt presents an opportunity to establish long positions at lows, with a medium-term target above 290,000 yuan/mt and a long-term target above 330,000 yuan/mt.

Weak supply and demand in fundamentals, short-term fluctuations in tin prices, "waiting for the wind" - macro factors may become the key to breaking the deadlock!

[SMM Monthly Outlook: LME and SHFE Tin Prices Decline for Two Consecutive Months; With Intensified Macroeconomic Game, the Pace of Production Resumptions in Major Producing Regions Becomes the Core Variable Affecting Tin Price Trends] Unlike the sharp decline in tin prices in April, tin prices in May generally fluctuated rangebound. As May month-end approached, despite the short-term tight supply situation of tin ore not yet improving, market expectations for supply recovery due to the gradual resumption of production at tin mines in Myanmar's Wa region and the DRC increased. Additionally, uncertainties surrounding the US tariff policy led to a cooling of market risk appetite, resulting in a significant correction in tin prices. As of around 18:10 on May 30, LME tin fell by 1.56% to $30,750/mt, with a temporary monthly decline of 1.91% in May; SHFE tin dropped by 2.87% to 250,300 yuan/mt, with a monthly decline of 4.39% in May.
