Product Overview
Ferrous sulfate monohydrate contains a controlled amount of crystal water compared to heptahydrate alternatives. This distinct hydration state alters both the molecular weight and the theoretical iron mass fraction, which must be factored into commercial fertilizer formulations.
Chemical Name: Ferrous Sulfate Monohydrate
Chemical Formula: FeSO4 x H2O
CAS Number: 17375-41-6
Physical Form: Free-flowing powder
Intended strictly for industrial and commercial processing, this material supports formulators seeking batch consistency, predictable dissolution, and compatibility with dry-blending or granulation equipment.

Industrial and Agricultural Applications
Fertilizer Manufacturing
Utilized as a raw material ingredient in compound fertilizers and NPK blends. Formulators evaluate the material based on:
Total iron concentration and chemical purity
Compatibility with dry-mixing and granulation processes
Particle size uniformity to prevent segregation in dry blends
Micronutrient Fertilizer Production
Iron is an essential micronutrient for correcting chlorosis and supporting plant enzyme systems. This monohydrate powder serves as a stable iron carrier when formulated into specialized soil or foliar micronutrient packages, subject to regional crop requirements and soil chemistry.
Agricultural Input Distribution
Sourced by regional chemical importers and distributors for repackaging or direct supply to commercial farming enterprises and blending plants. Distribution evaluation focuses on secure packaging, clear labeling, and comprehensive documentation.
Manufacturing Process & Quality Control
Our production process is designed to ensure strict batch-to-batch stability and controlled crystal water formation for industrial fertilizer applications.
Raw Material Screening: Incoming raw materials undergo strict inspection for purity and heavy metal profiles prior to reaction.
Controlled Dehydration & Crystallization: Precise thermal and chemical controls regulate the crystal water state to guarantee consistent FeSO4 x H2O composition without excess moisture.
Milling & Granulometry Control: Advanced mechanical grinding and multi-stage screening achieve the target particle size distribution required for dry blending or granulation equipment.
Automated Packaging Line: Products are sealed in moisture-barrier packaging under dry environmental conditions to prevent premature caking during transit.
Storage, Handling and Safety Guidelines
Proper handling procedures protect product integrity and maintain occupational safety during warehouse storage and downstream processing.
Hygroscopic Nature: Ferrous sulfate monohydrate is sensitive to moisture and air exposure. Store in a tightly closed container in a cool, dry, and well-ventilated facility.
Incompatibilities: Keep away from strong oxidizing agents, moisture, and alkaline substances to prevent chemical degradation or exothermic reactions.
Personal Protective Equipment (PPE): Operators handling fine powders should utilize approved dust masks, chemical-resistant gloves, and safety goggles to avoid inhalation or skin irritation as outlined in the Safety Data Sheet.
Quality Control and Documentation
To support rigorous supply chain auditing and import clearance, standard documentation packages are available upon request:
Certificate of Analysis (COA): Batch-specific verification reporting actual iron assay, moisture, and physical parameters.
Technical Data Sheet (TDS): Comprehensive guide covering physical properties, handling guidelines, and storage recommendations.
Safety Data Sheet (SDS): Detailed hazard communication, personal protective equipment requirements, and spill response procedures.
Packaging and Logistics
To protect product integrity during international transit and storage, flexible packaging configurations are provided:
Standard Packaging: Lined woven polypropylene bags or moisture-resistant multi-wall paper bags.
Bulk Options: Bulk bags (FIBC) available for high-volume manufacturing facilities.
Storage Guidelines: Store in a cool, dry, well-ventilated area away from incompatible materials. Keep containers tightly sealed to prevent moisture ingress and oxidation.
FAQ
Q: What is the theoretical iron content of ferrous sulfate monohydrate?
A: The calculated theoretical iron content of pure FeSO4 x H2O is approximately 32.9% by mass. Commercial product specifications are verified through laboratory testing for each production batch.
Q: How does monohydrate differ from heptahydrate in manufacturing?
A: Monohydrate contains one molecule of crystal water, offering a higher active iron percentage per kilogram and improved stability against caking compared to the heptahydrate form.
Q: What documents should be reviewed prior to placing a bulk order?
A: Buyers typically review the Technical Data Sheet, Safety Data Sheet, and a representative or batch-specific Certificate of Analysis to confirm quality alignment.
Q: Can particle size be adjusted for specific blending equipment?
A: Sieve analysis and particle sizing parameters can be evaluated based on the customer's specific manufacturing method, such as dry bulk blending or direct granulation.
