Report Summary 1. Report Industry Investment Rating No investment rating is provided in the report. 2. Core View of the Report - The Fed's July meeting minutes signaled a hawkish stance, with most believing inflation risk outweighs employment risk. In the tin market, despite Myanmar's restart of mining permit approvals, actual tin ore output will not occur until the fourth quarter, and the Congo's Bisie mine plans to resume production in phases. Currently, tin ore processing fees remain at historical lows. On the smelting side, production rebounded in July due to multiple factors, but raw material shortages are still severe in Yunnan, and the scrap recycling system in Jiangxi is under pressure with low operating rates. On the demand side, downstream processing enterprises are in the traditional off - season, with most maintaining only essential production and orders being mediocre. Recently, tin prices have fluctuated, with downstream enterprises making essential purchases at low prices. Domestic and LME inventories are on a downward trend. Technically, positions are decreasing, and both bulls and bears are cautious, expecting range - bound oscillations.

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.

Report Summary 1. Report Industry Investment Rating No information provided. 2. Core Viewpoints - The tin price showed a pattern of rising and then falling, with persistent upward pressure. It is expected to decline slightly in the coming week, with a weekly operating range of 262,000 - 272,000 yuan per ton [1]. - The mid - week increase in tin price was mainly due to the boost to the non - ferrous metal sector from anti - involution, while its own fundamentals remained largely unchanged. Considering the obvious oligopoly situation in the upstream of tin, the price increase is understandable. As the anti - involution heat fades, the tin price may decline slightly. Investors need to pay attention to the impact of various macro events in the last week of July on the tin price [1]. 3.
