Supply and Demand Analysis - **Supply Side**: In Myanmar, the Manxiang mine in Wa State has adjusted its fee standards, and the Bisie tin mine in Congo (Kinshasa) has复产. Domestic tin concentrate processing fees are oscillating downward, indicating a tightening supply of tin ore. The expected increase in scrap tin supply is difficult to change the tight situation. The operating rates of refined tin production in Yunnan and Jiangxi have decreased. Malaysia's MSC has suspended tin production, and Indonesia has adjusted its export policies. The inventory of refined tin in the Shanghai Futures Exchange has decreased, while the social inventory in China has increased [1]. - **Demand Side**: The daily processing fee of photovoltaic welding strips has decreased, which may lead to a decline in the operating rate and inventory of tin solder in May in China. The import and export volume of welding strips may change accordingly. The production volume of tin - plated sheets in May may increase, while the import and export volumes may decrease. The operating rate of lead - acid batteries in China has remained flat [1].
