SHANGHAI, Jun. 21 (SMM) – Spot tin prices in Shanghai continued to fall on Thursday with market depressed and LME tin prices slipping. Mainstream traded prices were mainly between RMB 139,000-140,500/mt, and low-priced goods increased. The decline in LME lead prices added to bearishness in the market, driving cargo holders to sell off, but downstream buyers were not interested in purchasing.
