SHANGHAI, Aug. 20 (SMM) – In Shanghai spot tin market, prices extended losses due to poor demand. Mainstream traded prices were RMB 106,000-107,300/mt on August 19. Some smelters began cutting output last month against falling tin prices and raw material shortages. Despite production cuts, market supply remained in surplus due to tepid demand.&nbsp;
