Copper sulphate, also named copper(II) sulfate, is a typical inorganic copper salt. It commonly exists as blue pentahydrate crystals (CuSO₄·5H₂O), while anhydrous copper sulphate appears as white‑grey powder.
It dissolves easily in water. Widely used in agriculture as fungicide, algaecide and copper trace‑element fertilizer. It is also an essential raw material for electroplating, copper salt synthesis, pigment manufacturing and laboratory analytical reagents. Our supply covers industrial‑grade and agricultural‑grade specifications.

FAQ ：Cobalt oxide
Q1: What grades of copper sulphate can you offer?
A1: We supply industrial grade and agricultural grade copper sulphate. Agricultural grade is optimised for crop disease control and trace‑element fertilisation; industrial grade applies to electroplating, chemical synthesis and other manufacturing scenarios. Customised specifications are available upon request.
Q2: Is copper sulphate crystal size adjustable?
A2: Yes. Regular products include large crystal, small crystal and powder forms. We can adjust crystal particle range according to your technical requirements to satisfy different end‑use conditions.
Q3: How about your product purity and batch consistency?
A3: Our standard industrial‑grade copper sulphate reaches minimum 98% purity. Strict purification and crystallisation processes control heavy‑metal impurities. Every production batch comes with full COA report to secure stable performance across batches.
Q4: What is your MOQ and production capacity?
A4: Our minimum order quantity (MOQ) is 100 kg. Sample testing orders and large‑volume wholesale are both acceptable. We keep sufficient manufacturing capacity to fulfil long‑term export bulk orders for industrial factories and research institutes.
Q5: What about packaging and shipping options?
A5: Standard package is 25 kg woven bag lined with inner plastic bag. Customised packing is supported. We arrange sea freight, air freight and courier delivery based on customer requirements.
Q6: Are your products compliant with international standards?
A6: Our copper sulphate is manufactured following ISO quality‑management requirements, satisfying import inspection standards for Europe, Southeast Asia, Americas and other global markets. Relevant supporting documents can be provided for customs clearance.
