[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.
