SHANGHAI, May 25 (SMM) – In Shanghai tin market, mainstream traded prices were between RMB 154,500-155,500/mt Thursday. Most transactions for Yunheng, and Yunxi concluded between RMB 155,000-155,500/mt, with a few deals for Kaiyuan and Nanshan done at RMB 154,500/mt. Since demand downstream remained weak, transactions were sparse even at low prices. Spot market was depressed on the whole due to the weak LME tin prices and worse-than-expected PMI data.
