Package and route
Packing notes
Advertised packing includes 20 kg woven bags, 25 kg kraft bags, and OEM package options
Confirm inner liner, moisture barrier, palletization, container loading plan, and bag marking before order
Request sample availability and sample COA before bulk shipment

Ask whether packaging can show feed additive, agriculture input, or technical-grade labeling according to destination requirements
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
Feed additive candidate requiring local regulatory and formulation approval before use
Aquaculture feed input candidate subject to residue, heavy metal, and feed-grade checks
Agricultural biostimulant or soil input candidate where humic acid content and solubility are key buying specs
Industrial humic substance application where pH, solubility, particle size, and dry-basis assay drive acceptance
OEM repacking programs for regional distributors after document and grade verification
