SHANGHAI, Apr. 9 (SMM) – In domestic spot tin markets, there were only three trading days last week, and spot tin prices fell RMB 1,500/mt to RMB 149,500-152,500/mt as of last Wednesday. Domestic tin prices were little affected by LME tin, but were dragged down by poor performance of other base metals. SHFE copper prices slumped last Monday, hurting market confidence, combined with waning tin demand, prices continued to fall with transactions limited.
