Potassium Humate / Potassium Humic Acid Shiny Flake from China
Buyer-facing sourcing profile for potassium humate shiny flake produced from leonardite, positioned for fertilizer, soil conditioner, fertigation, and formulation buyers. Key checks should focus on whether the material is potassium humate or humic acid potassium salt, confirmed CAS/HS alignment, humic acid and fulvic acid assay basis, K2O content, pH, water solubility, moisture, heavy metals, particle form, packing, COA readiness, and export documentation.

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 humic substance fertilizer formulations
Ingredient for water-soluble fertilizer blends where confirmed solubility is required
Soil conditioner and organic matter input after local registration review
Fertigation and drip-irrigation product formulation subject to compatibility testing by the buyer
Private-label agricultural input packing for distributors
How we compare
Sourcing options
Request the 80% total humic acid / 15% fulvic acid / 8% K2O shiny flake grade as the benchmark offer
Compare 60% humic acid grades where lower cost and broader formulation use are acceptable
Ask for powder or granule form if the buyer's blending equipment cannot process flakes
Request small trial sample before 1 MT MOQ order
Source with neutral export bag first, then move to buyer-branded packing after specification approval
Use third-party inspection for assay, moisture, heavy metals, packing count, and loading supervision
Human review
Compliance notes
Confirm whether the product is declared as potassium humate, potassium humic acid, humic acid potassium salt, organic fertilizer, or fertilizer additive in the destination market
Request current COA matching batch number, TDS/specification sheet, SDS, commercial invoice, packing list, and certificate of origin if needed
Check whether the destination country requires fertilizer registration, organic input approval, import permit, or label pre-approval before shipment
The source presents ISO9001 certification; request valid certificate copy and scope verification
DG status is likely non-dangerous for common potassium humate fertilizer grades, but buyer should request SDS transport section and non-DG statement before booking
Verify REACH, UK REACH, EU fertilizer regulation, EPA/state fertilizer rules, or other destination-specific requirements where applicable
Do not rely on marketplace wording such as '100% shiny flake' as a specification; define measurable assay and impurity limits in the purchase contract
Confirm that agricultural claims and label language are acceptable in the buyer's jurisdiction before resale
