SHANGHAI, Jul. 22 (SMM) – Spot tin prices in Shanghai were mainly between RMB 136,800-138,500/mt on July 19. Some smelters reported tin prices have fallen below their production costs and were unwilling to sell goods. Thus, low-prices goods were rarely seen in the market. The stable spot tin prices were mainly attributable to correction of LME tin prices and limited supplies from tin smelters, while transactions remained quiet.
