On May 29, the market price of electrolytic cobalt rose Yuan 68/tonne to Yuan 417,591-420,909/tonne. In addition, the market prices of cobalt sulfate and cobalt chloride both decreased Yuan 500/tonne to Yuan 90,000/t-94,000/t and 113,000-115,000/t respectively.Last week, the cobalt sulfate market showed a downward trend, with spot transactions dropping to below Yuan 90,000/tonne. Supported by persistently high sulfur costs and tight supply of cobalt intermediates, mainstream producers remained relatively strong in their price-stabilizing stance, while maintaining a generally cautious approach to production and shipments. Demand remained weak, with ternary precursor plants making only sporadic replenishment purchases, limited in volume and with significant downward price pressure. Most market players focused on consuming existing inventories, lacking the impetus to chase higher prices.
