SHANGHAI, Apr. 24 (SMM) – Mainstream traded prices in Shanghai spot tin markets were between RMB 141,500-142,500/mt on Tuesday, and trading for low-priced goods were enlivened. However, quotations for these goods were raised to RMB 142,000-143,000/mt with supply tightening. Thus, transactions turned light again as downstream buyers were reluctant to purchase at higher prices.
