Compliance notes
Request COA for each batch showing N, available P2O5, soluble K2O, moisture, particle size, water-insoluble matter, pH, and any requested impurity limits
Confirm whether the product is fully water soluble or only granular compound fertilizer described as soluble; require test method clarification
Check impurity requirements for destination market, including chloride, sodium, biuret, heavy metals, perchlorate, and insoluble matter if relevant
Request SDS, TDS/specification sheet, COA, commercial invoice, packing list, certificate of origin, and any fertilizer registration support documents available
Verify CAS, HS code, product name, and grade consistency across SDS, COA, invoice, bag label, and customs documents
Confirm DG status for sea/air transport with the supplier and freight forwarder; many NPK fertilizers may ship as non-dangerous goods depending on composition, but classification must be documented
Check destination-country fertilizer registration, import license, agricultural input approval, labeling, and contaminant limits before shipment
Do not rely on platform claims alone; verify supplier business license, manufacturing site, third-party audit, and batch traceability
