SHANGHAI, Jun. 9 (SMM) – In Shanghai physical tin market, mainstream traded prices were between RMB 139,000-140,500/mt last week. Goods from Yunnan Tin Group were offered higher at RMB 141,000/mt, but such high offers undermined buying interest. Yunxiang, Nanshan and Jinlong brand tin traded between RMB 139,000-139,500/mt. Most smelters held offers firm. Downstream producers were little interested in buying since the off-season has arrived.
