Humic Acid / Potassium Humate Granules or Powder for Agricultural Inputs
Buyer-facing sourcing candidate for humic acid or potassium humate supplied as black to brown powder, flakes, or granules. The listing indicates humic acid content around 40-65% dry basis, water solubility at or above 95%, moisture around 6.3%, and pH 8.6 for a 1% aqueous solution. Buyers should confirm whether the offered material is humic acid, potassium humate, or a coated shiny-ball fertilizer grade, and request lot-specific COA, impurity data, packing details, and export document readiness before RFQ confirmation.

Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Raw material for granular or soluble fertilizer formulations
Soil amendment and organic matter input sourcing
Micronutrient compatibility and chelation-oriented fertilizer blends
Agricultural distributor product line extension
Bulk import for repacking or private-label supply after local compliance review
How we compare
Sourcing options
Powder grade for soluble blends and formulation use
Granular grade for bulk fertilizer blending
Flake grade where rapid dissolution and lower dusting are preferred
Coated shiny-ball granule if the buyer specifically needs appearance-controlled fertilizer granules
Custom specification by humic acid content, moisture, pH, solubility, particle size, and heavy metal limits
25 kg bag packing with palletized export shipment
Human review
Compliance notes
CAS identity may not be straightforward because humic substances are variable natural mixtures; ask supplier to state CAS/EC information used on SDS and export documents
Request current SDS, COA, TDS, ISO certificate, heavy metal report, and origin declaration before purchase
Check destination-market fertilizer, soil amendment, organic input, or feed/aquaculture registration requirements before import
Do not rely on supplier claims such as non-toxic, residue-free, or disease-resistance benefits without destination-market label and regulatory review
Confirm whether the product is classified as dangerous goods for transport; humic acid/potassium humate products are commonly non-DG, but this must be verified by SDS and shipping documents
Clarify whether the material contains additives, binders, coating agents, potassium hydroxide residues, or other components affecting classification and import eligibility
For animal husbandry or aquaculture positioning, request separate compliance documentation and permitted-use confirmation for the target country

Questions to confirm
What is the exact product identity on COA, SDS, invoice, and customs declaration: humic acid, potassium humate, or coated humic acid granule?
What CAS number, EC number, and HS code will be used for export documentation?
Can you provide a recent lot-specific COA showing humic acid content, potassium content if applicable, moisture, pH, water solubility, particle size, ash, and insoluble matter?
Can you provide heavy metal results for Cd, Pb, As, Hg, and Cr, with test methods and detection limits?
Is the quoted grade powder, flake, granule, or shiny-ball coated material, and what is the particle size distribution?
What is the source raw material: weathered coal, lignite, peat, or another origin?
Are any binders, anti-caking agents, dyes, coatings, or soluble salts added?
What documents are available before shipment: SDS, COA, TDS, packing list, commercial invoice, certificate of origin, phytosanitary or fertilizer registration support if applicable?
