SHANGHAI, May 7 (SMM) – There were only three trading days last week due to the May Day holiday. Domestic tin prices moved up to RMB 164,000/mt on the first trading day following the holiday due to the rising LME tin prices and limited supply, with high-end prices remaining stable. On the last two days, spot tin prices presented a weak trend due to falling LME tin prices. Transactions became even quieter with strong wait-and-see sentiment in the market. Mainstream traded prices were between RMB 163,000-165,000/mt, with a few brands quoted at RMB 162,500/mt.
