SHANGHAI, Sept. 2 (SMM) – As tin smelters upstream failed to purchase large volumes of low-priced tin ores while LME tin prices were moving down from USD 29,000/mt to USD 22,000/mt, most of them have been holding goods on Sept. 2nd due to high raw material cost, thus leading to slightly tight supply in the market. After a three-day climb of SHFE tin prices, buying interest at downstream enterprises rose. However, traders lifted their quotes on tight supply and improved transactions. Mainstream tin brand was Nanshan in the morning, with trading prices of RMB 195,000-195,500/mt. Lvsejinnan and Jinlong joined Nanshan in the afternoon, with mainstream trading prices of 195,500-196,500/mt. Small volumes of Yunxi and Yunheng branded tin was traded at RMB 19,700/mt. Overall market transactions increased.
