1. Basic Information of Copper Sulfate Pentahydrate
Also known as blue vitriol, copper sulfate pentahydrate (CuSO₄·5H₂O) appears as bright blue transparent crystal particles with excellent water solubility.
It features stable physical and chemical properties, no deterioration under normal temperature, and strong adaptability for long-term sea transportation and long-time storage. The mainstream export purity is 98% and 99%.
Product quality mainly depends on heavy metal control. Qualified export products strictly limit lead, arsenic, cadmium and other impurities, meeting international safety standards for agriculture, feed and industrial use, ensuring smooth customs clearance.
With stable performance and cost advantages, copper sulfate pentahydrate keeps high repurchase rates and steady demand in Southeast Asia, Africa, South America, Europe and other global markets.
2. Main Industrial & Agricultural Applications
Agriculture & Aquaculture (Largest Consumption)
It is the core raw material for making Bordeaux mixture, a widely used broad-spectrum fungicide for fruits, vegetables and crops. It effectively prevents downy mildew, anthracnose and powdery mildew.
Besides, it serves as an essential copper trace fertilizer to supplement soil copper deficiency, improve crop growth and enhance disease resistance.
In aquaculture, it is widely used for algae removal, water purification and inhibiting harmful bacteria in ponds.
Livestock & Feed Industry
Feed-grade copper sulfate pentahydrate is an essential trace element additive for livestock and aquafeed. Copper promotes animal metabolism, accelerates growth and improves immunity, effectively reducing breeding diseases.
Our export feed-grade products are highly purified with ultra-low heavy metal content, fully compliant with international feed safety standards for large-scale breeding use.
Industrial Manufacturing
Electroplating industry: High-purity copper sulfate pentahydrate is the key electrolyte material for copper plating on hardware parts, auto accessories and PCB boards, providing bright, uniform, adhesive and anti-corrosion copper coating.
Chemical industry: It is the basic material for producing copper chloride, copper oxide, copper-based catalysts and other copper salt derivatives, widely used in coatings, pharmacy and fine chemical production.
Other industrial uses: It can be used as printing and dyeing mordant, wood preservative and mineral flotation agent for water treatment, metallurgy and construction industries.
3. Professional Buying Tips for Overseas Buyers
Different grades cannot be used interchangeably. Buyers should select suitable grades according to actual application instead of blindly choosing high-purity products.
Uniform and anti-caking crystals greatly reduce loss during long-distance shipping. Complete COA certificates and export documents guarantee smooth customs clearance and stable supply.
We supply full grades of copper sulfate pentahydrate with sufficient stock, supporting bulk container export and long-term stable orders for global clients.
