SHANGHAI, Apr. 25 (SMM) – In the Shanghai physical lead market, goods from Chihong Zn & Ge traded at RMB 13,970-13,980/mt, a premium of some RMB 60/mt over the most active SHFE 1405 lead contract price. Traded prices were RMB 13,950-13,960/mt for Nanfang and Chengyuan brands, and RMB 13,930/mt for Hanjiang, Shuangyan, and Humon resources. Physical lead supplied by smelters remained in shortage, while downstream producers mostly stayed on the sidelines. Poor battery sales reportedly caused some lead-acid battery producers to close in advance for May Day, hurting purchases of refined lead, with transactions unchanged Friday.
