SHANGHAI, Jan. 12 (SMM) – Shanghai spot tin prices climbed further to RMB 171,000-171,500/mt on Wednesday as tight supply continued and quotations were continually climbing. Mainstream spot tin brands were Jinhai and Nanshan. Mainstream futures tin brands were Yunxi, Yunheng and Jinhai. The downstream demand is turning weaker as tin consumers successively closed operation ahead of the Chinese New Year. Rapidly climbing tin prices also damped the buying interest. It is known that deals above RMB 170,000/mt during the day were mainly stock replenishment demand. Despite weak demand, the growing bullish sentiment may add further gains of the metal.
