SHANGHAI, Apr. 15 (SMM) – In the Shanghai physical lead market, goods from Chihong Zn & Ge traded between RMB 13,760-13,770/mt, initially at a par with the SHFE 1405 lead contract price but later at premiums of RMB 30-40/mt over the contract price. Traded prices were RMB 13,750/mt for Nanfang and Shuangyan brands, and RMB 13,730-13,740/mt for Humon resources. Smelters and traders cut back on delliveries in the wake of a sudden fall in SHFE lead prices, while downstream producers also expressed significantly lower buying interest with a wait-and-see posture. Traded volumes registered a marked drop Tuesday as against Monday’s level.
