Water-Soluble Organic/Inorganic Compound Fertilizer with Humic Acid, Amino Acid and Fulvic Acid Grades
Buyer-facing sourcing candidate for compound fertilizer products offered in multiple NPK-style grades such as 12-22, 8-30, 12-0-1, 12-0-0, 4-0-0 and 4-30. Suitable RFQ focus should be on confirmed grade basis, nutrient assay, humic/fulvic/amino acid content, water solubility, impurity limits, granule or powder form, packing format, export documentation and destination-market fertilizer registration requirements.
Quick buying facts
Identify the grade, package, and import market before comparing suppliers.
Use this page to check the product identity, common specification points, document scope, package notes, and destination-market questions before sending a China sourcing request.
CAS: Not applicable as a formulated fertilizer blend; request CAS or composition details for individual declared components if required by importerCompound fertilizer / organic water-soluble fertilizer / humic-acid and amino-acid fertilizer blendCandidate - requires specification, impurity and export-document verification
Water solubility: confirm complete/partial solubility, insoluble matter percentage and recommended label-compatible use category without requesting handling procedures
pH or acidity/alkalinity: page references chemical neutral and physiological acid; request tested pH range and method
Moisture content: request maximum moisture and caking tendency
Impurity checks: request limits for heavy metals such as Cd, Pb, As, Hg and Cr, plus chloride, sodium, biuret if relevant to the formulation
Microbiological or manure-derived risk checks: if manure/agricultural waste is used, request pathogen and maturity/composting compliance data where required by destination market
Certification references: supplier page mentions ISO9001, ISO14001 and ISO45001; request current certificate copies and scope coverage
Customization: source indicates OEM/ODM and customized size, shape, color and specification available; verify MOQ, lead time and validated specification sheet
Who uses this page
Target buyers
Fertilizer importers and distributors
Agricultural input wholesalers
Private-label fertilizer brands
Fertigation and water-soluble fertilizer suppliers
For water-soluble products, ask for anti-caking protection, inner liner material and storage stability data
Confirm whether private label, OEM artwork and destination-language label support are available
Sample availability is indicated on the source page; request sample size, sample specification and whether it matches bulk production
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.

Human review
Compliance notes
Fertilizer blends are typically not identified by a single CAS number; importers should review component disclosure, nutrient analysis and destination fertilizer-labeling rules
Request SDS, COA, TDS/specification sheet, ingredient declaration, packing list, invoice and certificate of origin before shipment
Confirm whether the product is classified as non-DG for sea/air/road transport and request the applicable transport classification statement or SDS section 14
No regulatory approval or market-entry guarantee should be assumed from supplier certifications; buyer should verify destination-country fertilizer registration, labeling and customs requirements
If organic certification is needed, request valid certification for the specific product and production site, not only general company claims
If manure, agricultural waste or seaweed-derived materials are used, confirm compliance with destination biosecurity, contaminant and organic-input rules
Check heavy metal and contaminant limits against target market standards before placing bulk orders
Verify that claims such as quick-acting, organic, soil remediation or crop quality improvement are supported by compliant documentation for the buyer’s market

What are the tested contents of humic acid, fulvic acid, amino acids, organic matter, seaweed extract and moisture?
Is the product granular, powder, flake or liquid? What is the particle size distribution and water-insoluble matter percentage?
Can you provide a recent COA from the same production line and a third-party test report for heavy metals and key impurities?
What raw materials are used, and are manure or agricultural waste inputs included in this specific product?
Is the product fully water soluble for fertigation use, or is it intended for soil application as a solid fertilizer?
What packing sizes are available for export orders, and what is the container loading quantity for each option?
