The prices of cobalt sulfate remained stable last week due to the suspension of quotations by top-tier cobalt intermediate companies, a small number of domestic quotations and overseas transaction prices increased, resulting in rising costs for cobalt sulfate companies and concerns about the tight supply of cobalt raw materials affecting production. In this case, market prices have risen by nearly Yuan 10,000/tonne. In terms of transactions, there are a small number of transactions between Yuan 41,000/t-50,000/t. Thus most market players did not purchase due to significant price fluctuations and consecutive increases, with only a few downstream customers restocking in small quantities due to low raw material inventory.
