Packing notes
Common export packing indicated: 25 kg bag.
Reported loading reference: about 13 tons per 20GP; confirm actual palletization, container loading, and moisture protection.
Ask whether bags are kraft paper, woven PP, PE-lined, or customized for sea freight.
Confirm net weight, gross weight, pallet dimensions, and whether fumigation-free pallets are available.
Request photos of inner liner, bag marking, batch label, and pallet wrapping before shipment.
Applications and sourcing options
