SHANGHAI, Aug. 18 (SMM) – Mainstream trading prices of spot tin in Shanghai slightly fell on August 17th, with Yunxi, Yunheng, Nanshan and Kaiyuan trading at RMB 196,000-198,000/mt and small volumes of Yunxi branded low-lead tin trading at RMB 198,500/mt. Market transactions turned even more sluggish during the day after LME tin price fell further to dampen buying interest. Tin supplies remained tight, but no shortage was reported due to weak consumption. Given sluggish world economies, power restrictions and tight capital supply etc., most market players expect the conventional peak season to come later this year.
