SHANGHAI, Nov. 22 (SMM) – In Shanghai spot tin market, mainstream traded prices were RMB 143,500-146,000/mt on Thursday, with a few goods of Yunnan Tin Group sold at RMB 146,500/mt. Wait-and-see sentiment permeated in the market due to the directionless LME tin prices, and smelters confronted great sales pressure given the tight cash flow by year’s end, dragging down spot tin prices.
