Packing notes
Common export packing listed as 25 kg kraft bag.
Smaller packs listed include 1 kg aluminum foil bags, color boxes, cartons, and customized packaging.
Confirm net weight, liner material, moisture barrier, palletization, container loading quantity, and whether retail packs require destination-language labeling.
Request photos of current production packaging and export marks before shipment.
Confirm whether private label or neutral export packing is available and whether it changes MOQ or lead time.
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.

Compliance notes
Confirm CAS 16455-61-1 and EINECS 240-505-5 against the supplier COA, SDS, label, and any fertilizer registration dossier.
Request COA showing total Fe, chelated Fe, ortho-ortho Fe, pH, insoluble matter, moisture, particle size, and solubility.
Ask for impurity checks relevant to agricultural inputs, including heavy metals such as Pb, Cd, Hg, As, and Cr, plus any destination-market fertilizer contaminant limits.
Request current SDS in GHS format and confirm transport classification before booking shipment.
Verify whether the product is non-DG for sea and air freight or if any local carrier classification applies.
Check destination country fertilizer, micronutrient, organic input, REACH, UK REACH, TSCA, AICIS, or other inventory and registration obligations as applicable.
No regulatory approval or market access should be assumed from the listing; buyer should validate with importer of record and local authorities.
Confirm whether the product is technical grade, fertilizer grade, agricultural grade, or a registered finished fertilizer in the destination market.
