SHANGHAI, Sept. 13 (SMM) – Spot tin prices in Shanghai fell to at RMB 148,000-149,000/mt on Thursday, but traders held their quotations firm due to a lack of inventories and considering the directionless LME tin prices which was testing support at an earlier high level. Downstream buyers continued to purchase as needed, leaving few transactions made. In this context, suppliers and downstream buyers were still in a gridlock.
