SHANGHAI, Nov. 25 (SMM) –Shanghai spot copper offers were quoted between premiums of positive RMB 500-650/mt today. Traded prices for standard-quality copper were between RMB 55,400-55,600/mt, and RMB 55,500-55,750/mt for high-quality copper. SHFE copper prices fluctuated around RMB 55,000/mt, and supply of imported copper increased due to slight profits, dampening premiums for high-quality copper. However, declines in premiums for standard-quality copper were limited. Cargo-holders of hydro-copper were still seen to move goods for cash generation, and market transactions were modest.
