Group 1 - The core viewpoint indicates that the tin price trend in the second half of 2025 is dominated by global supply tightness, with significant influences from Myanmar's slow recovery and Indonesia's crackdown on illegal mining, alongside macroeconomic factors supporting price increases [1][4] - The recovery of tin production in Myanmar is expected to be the main driver for marginal supply improvement in Q4 2025, with imports from Myanmar anticipated to steadily increase, alleviating raw material inventory issues in Yunnan smelting plants [2][4] - Domestic refined tin production faced constraints due to raw material shortages, with September production dropping significantly by 34.69% to 9,770 tons, but is expected to rebound as raw material supply improves and smelting capacities are gradually released [2][3] Group 2 - The traditional consumption sectors for tin, particularly the electronics market, continue to show weak performance, with a reported 6.0% year-on-year decline in domestic mobile phone shipments in August 2025 [3] - The photovoltaic sector is also under pressure, with a 1.8% year-on-year decline in newly installed solar capacity in Q3 2025, indicating overall demand weakness [3] - The overall demand for tin is expected to remain weak, limiting the price support from the demand side, despite some growth in tin consumption from AI servers [3][4] Group 3 - The tin market in Q4 is characterized by "marginal supply improvement and continued demand weakness," with supply growth from Myanmar and Indonesia putting pressure on tin prices, while low global tin inventories and macroeconomic factors provide limited downside [4] - The Shanghai tin main contract is projected to fluctuate within the range of 270,000 to 300,000 yuan per ton, with close attention needed on the actual supply increase from Myanmar and changes in domestic and international macro policies [4]

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]
