Buyer-facing sourcing candidate for an organic seaweed extract micronutrient fertilizer from a Made-in-China listed supplier. The listing indicates seaweed-based crop nutrition with alginate, phosphorus, potassium, organic matter, and trace elements for drip-irrigation programs. Key buyer checks should focus on physical form confirmation, guaranteed analysis, heavy metals, microbial limits, crop input registration documents, export packaging, and batch-level COA readiness.

CAS: Not applicable as a blended fertilizer/seaweed extract formulation; request component disclosure and registration classification by destination market.
Physical form: Listing title describes liquid root fertilizer, while attributes mention powder/solid; confirm whether supplied as liquid concentrate, soluble powder, or both.
Main active indicators from listing: alginate ≥90 g/L, P2O5 ≥30 g/L, K2O ≥60 g/L, organic matter ≥120 g/L, trace elements TE ≥20 g/L.
Alternative value shown in extracted specs: alginate ≥60 g/L; request current TDS and COA to resolve specification inconsistency.
Grade: Agricultural fertilizer grade / commercial organic fertilizer; confirm suitability for organic agriculture programs only where supported by recognized certification.
pH/chemical character: Listed as chemical neutral/physiological neutral; request actual pH range and density for liquid product.
Application category: vegetables, flowers, fruit, drip irrigation crop nutrition; verify local agronomic labeling requirements before import.
Impurity checks: heavy metals such as As, Cd, Pb, Hg, Cr; chloride, sodium, insolubles, microbial load, pathogens, and any undeclared plant growth regulators or synthetic chelants.
Batch consistency: request guaranteed minimum analysis, test method references, shelf-life, and retain-sample policy.

Package and route
Packing notes
Confirm available packing by form: liquid drums/IBC/totes or powder bags/cartons; the listing does not provide final export packing details.
For liquid concentrate, ask for net weight/volume per drum, drum material, cap/seal type, palletization, leak-test practice, and temperature range during storage/transit.
For powder/solid, ask for moisture barrier bag structure, inner liner, bag size, pallet dimensions, anti-caking controls, and container loading quantity.
Request export marks, batch number, manufacture date, shelf-life, and label language options for destination-market registration.
MOQ shown on listing is 12 L; confirm commercial MOQ, sample availability, lead time, and whether OEM/ODM labels are supported.
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
Crop nutrition programs for vegetables, fruit, and flowers
Drip-irrigation compatible seaweed extract fertilizer programs, subject to solubility confirmation
Micronutrient supplementation in commercial agriculture
Private-label organic or bio-based fertilizer product development, subject to certification and registration checks
Trial formulation sourcing for regional fertilizer distributors
How we compare
Sourcing options
Request liquid concentrate samples with batch COA for lab verification before commercial purchase.
Request powder/solid sample if the supplier offers a water-soluble version and compare solubility, moisture, and assay results.
Ask supplier for OEM/ODM nutrient adjustment where destination labels require specific N-P-K or micronutrient declarations.
Source under neutral export labeling first for registration review, then move to private label after compliance approval.
Compare with alternative seaweed extract suppliers using standardized COA, heavy metal, and microbial limits.
Human review
Compliance notes
This is a fertilizer/crop input candidate, not a single CAS chemical; import acceptance depends on destination-country fertilizer, biostimulant, organic input, and labeling rules.
Request SDS, TDS, COA, product label, ingredient disclosure, heavy metal report, microbial/pathogen report, and certificate of analysis for each batch.
Verify whether the product is classified as dangerous goods for transport. Seaweed fertilizer is often non-DG, but classification must be confirmed by supplier SDS and logistics documents.
Check export documentation readiness: commercial invoice, packing list, certificate of origin, MSDS/SDS, phytosanitary or organic-input documents where applicable, and destination-specific fertilizer registration support.
Do not rely on marketplace claims such as 'organic' or 'fast acting' without third-party certification, guaranteed analysis, and local registration review.
Confirm whether micronutrients are chelated, inorganic salts, or naturally occurring, and check whether any substances are restricted in the buyer's market.
For organic agriculture programs, request recognized certification or input approval documentation rather than assuming organic eligibility from the product name.
