Persistent weakness on the demand side remained the primary factor weighing on the cobalt chloride market. Key downstream application segments, such as Co3O4, experienced sluggish demand. At the same time, cobalt sulfate exerted a certain substitution effect on cobalt chloride, as its lower price made it more attractive to some buyers. Downstream consumers largely relied on drawing down their existing inventories, resulting in very sparse market inquiries and virtually negligible actual transaction volumes.Trading activity in the cobalt sulfate market was particularly subdued, with no large-scale transactions observed throughout the entire week. Although high raw material costs discouraged smelters from selling at a loss, thereby providing some price support, the sustained release of low-cost feedstocks, such as recycled materials and electrolytic cobalt dissolution solution, continued to exert downward pressure on mainstream quotations.
