1. Report Industry Investment Rating - No relevant information provided 2. Core View of the Report - The current Shanghai tin market is in a situation where macro factors are mixed. The long - term logic of tight supply and demand remains unchanged, but in the short term, due to weak demand before the National Day holiday, profit - taking by funds, and risk - aversion sentiment from trade frictions, the upside potential of prices is limited [11] 3. Summary by Related Catalogs 3.1 Variety Price - The total trading volume of 12 Shanghai tin futures contracts is 84,373 lots, and the total open interest of Shanghai tin contracts is 52,516 lots. Among them, the open interest of the Shanghai tin contract 2511 is 46,590 lots [6][7] - The closing price of the Shanghai tin 2511 contract today is 272,410 yuan/ton, the mainstream market quotation on the day is 271,400 yuan/ton, and the basis is - 1,010 yuan/ton [8] 3.2 Influencing Factors - Supply side: The long - term logic of tight global tin ore supply remains unchanged, but in the short term, the tin inventory on the London Metal Exchange (LME) has slightly accumulated. On September 26, the inventory increased by 35 tons to 2,775 tons compared with the previous day. The inventory change has put some pressure on the spot price and weakened the premium power on the spot side [10] - Demand side: As the National Day holiday approaches, downstream enterprises' stockpiling is coming to an end. The demand in traditional industries such as tin - plated sheets is approaching saturation, and the "new quality requirements" driven by AI and new energy have not yet formed short - term upward - pulling power. The light trading in the spot market has made it difficult for the spot price to rise and keep up with the fluctuating futures price [10]

1. Report Industry Investment Rating No information provided in the document. 2. Core View of the Report - This week, the main contract of Shanghai Tin fell from a high, with a weekly decline of 2.22% and an amplitude of 2.86%. As of the end of this week, the closing price of the main contract was 272,460 yuan/ton. - Macroeconomically, the expansion speed of the US ISM Services PMI reached the fastest in half a year, with weak employment and high prices. The ADP employment growth in the US in August slowed down significantly to 54,000 people. The number of initial jobless claims in the US last week was 237,000, reaching the highest level since June. - Fundamentally, although Wa State in Myanmar has restarted the approval of mining licenses, actual ore production will not occur until the fourth quarter. The Bisie mine in Congo plans to resume production in phases, and currently, the tin ore processing fee remains at a historical low. - On the smelting side, the increase in production in July was mainly due to multiple factors such as the resumption of production by some enterprises and the cleaning of intermediate products. However, the shortage of raw materials in the Yunnan production area remains severe, and the waste recycling system in the Jiangxi production area is under pressure, with the operating rate remaining at a low level. - On the demand side, downstream processing enterprises are in the recovery period of the peak season, and the recovery of orders is relatively slow. Recently, the tin price has oscillated downward, but most downstream and end - user enterprises still adopt a wait - and - see attitude, and some downstream enterprises make small - scale purchases. The spot premium has rebounded to 200 yuan/ton, and domestic inventories have increased. LME inventories have rebounded, and the spot premium has been adjusted downward. - Technically, as the position decreases and the price falls, the bullish sentiment is cautious. Attention should be paid to the competition around the MA10. - Operationally, it is recommended to wait and see temporarily, and pay attention to the range of 270,000 - 276,000 yuan/ton. [5] 3.

1. Report Industry Investment Rating - The report does not explicitly mention an industry investment rating. 2. Core View of the Report - The tin price showed a slight increase during the week and is expected to mainly fluctuate in the future. The price resilience reflects the characteristics of relatively high supply concentration and relatively scattered downstream demand in the tin market. The repeated delay of the full resumption of tin mines in Myanmar has significantly supported the tin price and may have a continuous impact. The expected weekly operating range is between 262,000 - 269,000 yuan per ton [2]. 3. Summary by Relevant Catalogs 3.1.

1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - This week, the main contract of Shanghai Tin fluctuated weakly, with a weekly decline of -0.60% and an amplitude of 2.08%. As of the end of this week, the closing price of the main contract was 267,250 yuan/ton [4]. - Macroscopically, the non - farm payrolls in the US in June exceeded expectations, the unemployment rate unexpectedly dropped, and the Fed's interest - rate cut expectation decreased significantly. Fundamentally, the resumption progress of tin mines in Myanmar's Wa State is uncertain, and Thailand has restricted the import of tin ore. The Bisie mine in Congo plans to resume production in stages, and the tin ore processing fee remains at a historical low. On the smelting side, raw material shortages and cost pressures coexist in Yunnan, and the waste recycling system in Jiangxi is under pressure with a low operating rate. On the demand side, after the rush to install in the photovoltaic industry, the operating rate of some producers has decreased, and the electronics industry has entered the off - season with a strong wait - and - see attitude. Recently, the tin price has corrected, the spot premium has been lowered, and domestic inventories have increased slightly, but overseas inventories continue to decline [4]. - Technically, the positions are stable, and both long and short sides are cautious. Attention should be paid to the adjustment at the 270,000 yuan mark, with the 10 - day moving average providing support [4]. - It is recommended to wait and see for now, with a reference range of 266,000 - 272,000 yuan [4]. 3.

Report Summary 1. Investment Rating - No investment rating provided in the report. 2. Core View - Recently, the tin price has corrected, and the spot premium has rebounded to 600 yuan/ton, but the trading volume is light.
