Humic Acid Manufacturing, OEM Formulation & Global Supply
Saint Humic is a China-based manufacturer and supplier of humic substances and agricultural ingredients, serving fertilizer producers, agricultural distributors, private-label brands and industrial customers.
Since 2010, our business has focused on humic acid, potassium humate, sodium humate, fulvic acid and related materials. Over time, we have expanded our product range to include amino acid fertilizers, seaweed extracts and customized agricultural formulations.
Through CNHumicAcid.com, we bring together product manufacturing, specification development, quality coordination, OEM services and international supply.
We understand that customers do not always need the same product. A potassium humate used in a water-soluble fertilizer may require different properties from one used for soil application. Likewise, a bulk material purchased for fertilizer blending requires different attention from a finished product prepared for retail distribution.
Our work begins with understanding those differences.

Our Products and Supply Capabilities
Humic substances remain the foundation of our business.
Our main product range includes humic acid powder and granules, potassium humate, sodium humate, ammonium humate, nitro humic acid, fulvic acid and potassium fulvate.
We also supply selected amino acid fertilizers, seaweed extracts and specialty agricultural ingredients used in fertilizer and biostimulant formulations.
Humic Acid & Humates
Humic acid, nitro humic acid, potassium humate, sodium humate and ammonium humate.
Fulvic Acid
Mineral fulvic acid, bio fulvic acid and potassium fulvate.
Humate Blends
Boron, silicon and chitin humate, and customized humic blends.
Amino Acids
Amino acid from animal and plant sources, polyglutamic acid granules and L-proline.
Seaweed Extract
Seaweed extract in liquid, powder and flake forms.
Carbon Fertilizer
Carbon-rich base fertilizer, Carbon Fertilizer Plus, Carbon Guard and organic carbon for fertigation.
Depending on the product, available physical forms include powder, granules, flakes, crystals and liquid concentrates.
Product selection is based on practical requirements rather than a single headline specification. For example, a high humic acid percentage does not necessarily mean that a material will dissolve completely in water. Raw humic acid and soluble potassium humate also behave differently under acidic conditions.
For customers manufacturing liquid fertilizers, we pay particular attention to solubility, pH, sediment formation and compatibility with other ingredients.
For dry fertilizer manufacturers, particle size, moisture, handling properties and blending consistency may be more important.
Our objective is to match the material to the process in which it will actually be used.
Manufacturing and OEM Services
Saint Humic supports standard bulk supply as well as customized manufacturing and private-label projects.
Customers may require a particular humic acid content, potassium level, physical form or packaging format. Others may have an existing formulation and need a suitable raw material or a manufacturer capable of preparing a finished product.
Our manufacturing and OEM services cover product-grade selection, specification adjustment, selected powder and liquid formulations, customized packaging, label preparation and export order coordination.
For private-label orders, we discuss the destination market, packaging size, label requirements and product specifications before confirming production arrangements.
Not every formulation can be produced simply by combining ingredients. Humic materials may react differently in systems containing calcium, acidic components or concentrated mineral nutrients. Where compatibility is uncertain, laboratory evaluation or a small-batch trial is recommended before commercial production.
We prefer to resolve these questions before an order moves into full-scale manufacturing.
Quality Control and Product Specifications
Consistent specifications matter particularly in humic products, where raw material origin, extraction conditions and testing methods can influence reported results.
Our quality process includes raw-material evaluation, specification confirmation, finished-product testing and packaging inspection, according to the requirements of each product and order.
Depending on the grade, important quality parameters may include:
- Humic acid or fulvic acid content
- Test method and reporting basis
- Water solubility and insoluble matter
- pH and moisture content
- Potassium, sodium or other relevant mineral content
- Ash content
- Particle size or granule characteristics
- Heavy metals and other market-specific requirements
We can discuss Certificates of Analysis (COA), Technical Data Sheets (TDS), Safety Data Sheets (SDS), batch identification and third-party testing requirements.
Because humic substance measurements can vary between analytical methods, buyers comparing products from different suppliers should confirm that the results are reported on a comparable basis.
For custom specifications, the agreed test method and acceptance criteria should be established before production.
International Supply and Export Support
Saint Humic works with overseas customers purchasing agricultural raw materials, fertilizer ingredients and customized products from China.
We support bulk purchasing, distributor supply and OEM export arrangements.
International orders involve more than the product specification. Packaging strength, moisture protection, shipping conditions, destination regulations and documentation can all affect whether a shipment meets the customer’s requirements.
Our team coordinates packaging, order documentation and export arrangements according to the agreed commercial terms.
For a new inquiry, we normally begin by reviewing the intended application, target specification, required quantity, packaging preference and destination country or port.
Where a standard grade is suitable, we can discuss the available specification and quotation. Where the requirement is more specific, we can review a reference COA, technical specification or formulation request before proposing an alternative.

Applications We Serve
Our products are used across several markets, particularly fertilizer manufacturing and agricultural formulations.
Humic acid and humates are used in soil conditioners, organic fertilizers, compound fertilizers and selected water-soluble fertilizer systems.
Fulvic acid, amino acids and seaweed extracts are used in foliar nutrition, fertigation and biostimulant formulations.
Selected sodium humate and other humic grades may also be considered for animal nutrition or industrial applications, subject to the applicable product specifications and regulatory requirements.
We recognize that agricultural, feed and industrial grades are not interchangeable. Product selection must take account of the intended use and relevant market requirements.
Trade fairs
We meet distributors, fertilizer producers and other buyers at agricultural and fertilizer trade fairs, where we discuss product grades, samples and documents in person. Faces have been blurred for privacy.
