SHANGHAI, Feb. 4 (SMM) – In Shanghai tin market, spot prices were mainly between RMB 159,500-161,000/mt on Friday. Goods holders held prices firm and quotations for Yunxi and Chengfeng were adjusted upward, driving up spot prices. Trading was quieter with the Chinese New Year holiday approaching, leaving little buying support for tin prices.
