Import Cobalt Sulfate — Buy in Bulk from Supplier in China

Cobalt sulfate offered by Hanyu International Trading (Hongkong) Co., Limited is supplied in two distinct grades, Grade A and Grade B. Grade A contains a cobalt content of at least 21 % by weight, while Grade B provides a minimum of 20.5 % cobalt. The compound is typically supplied as the heptahydrate form, CoSO4·7H2O, appearing as a white crystalline powder. The supplier’s data highlights low levels of trace metals such as nickel, iron, copper, manganese and zinc, which is important for high‑purity applications.

High‑purity cobalt sulfate is a key intermediate in lithium‑ion battery cathode production, pigment manufacturing and catalyst formulation. Typical specifications for this chemical include a purity of ≥98 % and a solubility of about 30 g per 100 ml of water at 20 °C. The material’s hygroscopic nature requires careful handling and storage in airtight containers. Standard bulk packaging consists of 25 kg fiber drums or 1 tonne bulk bags, aligning with common chemical logistics practices.

Battery manufacturers, ceramic producers and fertilizer formulators commonly source cobalt sulfate for its electrochemical stability and ability to impart colour properties. Prospective buyers should request a certificate of analysis and verify the specific grade before committing to a purchase. Hanyu International Trading provides flexible ordering quantities, with payment options such as L/C or T/T, and can discuss incoterms based on the buyer’s shipping preferences. Final shipping arrangements and lead‑time estimates should be confirmed directly with the supplier.
