Zinc sulfate monohydrate (ZnSO₄·H₂O) is a white granular powder with 36.5% elemental zinc. Its single water molecule locks stability-no efflorescence, no liquefaction in humid transit.
This density favors bulk logistics. Fertilizer producers blend it into NPK formulations at lower inclusion rates; feed mills dose premixes with reduced handling volumes. Both cut freight costs against heptahydrate competitors.
Alkaline soils reveal its practical edge. Zinc fixation by carbonates and phosphates demands higher application rates; the monohydrate's concentrated zinc reduces per-hectare bulk. Foliar programs on mango and banana plantations across Southeast Asia and Latin America rely on this efficiency.
Industrial electroplating and water treatment consume secondary volumes. The granular form flows through hoppers without bridging, a mechanical advantage over powdery alternatives.
Storage requirements relax accordingly. Poly-woven bags with moisture barrier suffice; climate-controlled warehousing is unnecessary. Shelf life extends 24–36 months unopened, with caking only after prolonged exposure.
Advantage
High Zinc Density
Our Monohydrate form contains 35% min elemental Zinc, offering a higher concentration than Heptahydrate, which significantly reduces shipping and storage costs.
Superior Physical Stability
Available in both fine powder and uniform granular forms with low dust, ensuring excellent flowability and ease of blending in bulk-blend fertilizers.
Feed-Grade Safety Standard
Produced under strict QC, Lead (Pb) and Cadmium (Cd) are controlled well below international standards, making it safe for high-end animal nutrition and premixes.
Efficient Nutrient Release
The optimized solubility provides a balanced release of Zinc and Sulfur, promoting enzyme activity in crops and enhancing metabolic efficiency in livestock.

Applications
Feed Additive : A vital nutritional supplement for livestock and poultry. It promotes growth, strengthens the immune system, and prevents parakeratosis and other zinc-deficiency symptoms.
High-Efficiency Fertilizer : Widely used in the production of compound fertilizers and foliage sprays. Due to its high Zn content (35%+), it is more cost-effective for long-distance transport and large-scale farming.
Mineral Flotation : Functions as a depressant in the flotation separation of multi-metal ores, particularly for inhibiting zinc minerals during lead recovery.
Industrial Chemicals : Used in the production of zinc salts, synthetic fibers, and as a raw material in the electroplating industry.
Water Treatment : Acts as a coagulant and preservative in various industrial water treatment processes.
