Cobalt tetroxide (Co3O4) supplied by Fairsky Industrial Co., Limited is a black powder with an agglomerated morphology. The material carries CAS No. 1308-06-1 and a molecular weight of 240.80 g·mol‑1. Its loose bulk density ranges from 0.7 to 1.5 g·cm‑3 while tap density lies between 2.5 and 3.5 g·cm‑3. Particle size analysis shows a median (d50) of 4.0‑6.0 µm. BET surface area is reported at 0.6‑1.5 m²·g‑1. Impurity assay limits specify Fe, Ni, Mn, Cu, Pb, Ca, Na, Mg and Zn each not exceeding 0.005 % by weight. The supplier packs the powder in net‑weight 25 kg drums.
The fine powder conforms to analytical‑grade standards common for catalyst precursors, where particle sizes of 2‑10 µm and surface areas of 0.5‑2 m²·g‑1 are typical. The reported bulk densities indicate good flowability for bulk handling operations.
Major end‑users include lithium‑ion battery producers, specialty glass makers and magnetic material developers. Buyers should request a current MSDS, a certificate of analysis and clarify MOQ, Incoterms and payment method with the supplier before placing an order.

Before placing an order, importers should obtain a current material safety data sheet and a certificate of analysis that confirms the bulk density, particle size and impurity limits reported by Fairsky. Verifying the supplier’s business licence and checking any third‑party audit reports can also reduce risk, especially given the zero‑response rate shown in the platform data.
Logistics for bulk chemicals from China typically involve sea freight with FOB or CIF terms. Because lead times and payment conditions are not disclosed, buyers must ask the supplier to specify expected production lead time, preferred Incoterms and acceptable payment methods such as T/T, L/C or open account.
Quality assurance commonly includes pre‑shipment sampling, third‑party laboratory testing for purity and particle size, and a final visual inspection of drum sealing. Importers should arrange for an independent inspection agency to verify that the drums are intact, correctly labelled and that the documentation matches the shipment. All relevant certificates, including the MSDS and COA, should be retained for customs clearance and downstream quality control.
