SHANGHAI, Apr. 4 (SMM) – In the Shanghai physical lead market, goods from Chihong Zn & Ge, Nanfang, and Chengyuan traded Friday at RMB 13,680/mt, a discount of around RMB 35/mt over the SHFE 1405 lead contract prices. Shuangyan resources were sold at RMB 13,670/mt for steel-plastic supply and RMB 13,630-13,640/mt for iron sheet supply, while Humon traded at RMB 13,660/mt. Supply from Chihong Zn & Ge, Nanfang, and Chengyuan was barely found in the market, with only over 4,000 mt of warrants in Shanghai.
