SHANGHAI, Jul. 17 (SMM) – Shanghai spot tin markets remained stable Tuesday, with mainstream traded prices at RMB 137,000-138,000/mt in the morning trading session. Some goods from Nanshan were traded at RMB 136,800/mt. In the afternoon, a few goods were quoted lower at RMB 136,500/mt, but inquiries were still sparse, and traded prices edged lower to RMB 136,800-138,000/mt. Low tin prices and high input costs, combined with stricter environmental protection crackdown in some regions caused smelters to cut production, and the limited supplies helped limit decline in prices. However, as consumption remained sluggish, spot prices may fall further if LME tin stay weak.
