How International Buyers Can Evaluate a Vietnamese Fresh Durian Packing Facility: A Factory Visit Checklist

Observe whether the facility can connect each inbound durian lot to an approved growing area or supply area.
Check whether growing-area codes, packing-facility codes, harvest dates, receiving dates and supplier names are recorded consistently.
Ask how the packer verifies that the growing area and packing facility remain eligible for the destination market at the time of shipment.
Ask whether the facility can conduct a traceability test from packed carton back to growing area, receiving lot and harvest date.

Observe whether incoming durians are separated by lot, supplier, harvest date and inspection status.
Check how immature, overripe, cracked, pest-infested, rotten, damaged or soil-contaminated fruits are rejected before packing.
Observe whether maturity assessment is based on clear acceptance criteria, not only visual judgment.
Ask how the facility records fruit condition, rejection rate and corrective actions at receiving.
Ask how fruit cleaning, surface handling and staff hygiene are controlled before packing.

Observe whether raw-material, inspected-fruit and finished-product zones are clearly separated.
Check whether the packing area has clean floors, controlled waste flow, clean tools and hygienic staff movement.
Review whether cartons, liners and other packaging materials are clean, unused and stored away from contamination risks.
Ask how labels are checked against growing-area code, packing-facility code, product name, destination market and shipment document details.
Ask whether wooden packaging, if used, meets ISPM 15 requirements.

Review phytosanitary records, pre-export inspection files, pest-monitoring records and corrective-action logs.
Ask how the facility prepares for the required quarantine sampling before export.
Check whether documentation, labels, packing lists, phytosanitary certificates and customs declarations match exactly.
Ask how the facility handles a live pest, soil, plant-residue, chemical-residue or documentation discrepancy finding.
Ask whether management reviews nonconformities and updates procedures before the next shipment.

Why this matters for buyers

Packing facilities need traceability systems that can link exported durians back to registered orchards, processing and packing dates, registration codes, quantities, container information and shipment details. (Source: Vietnam Trade Portal / Customs Magazine)
Shipments that contain regulated pests, soil, plant residues or food-safety nonconformities may be refused entry, returned or destroyed at the port of entry. (Source: Vietnam Trade Portal / Customs Magazine)
For buyers, a durian packing facility visit should test whether the supplier can control code eligibility, fruit selection, traceability and quarantine readiness at lot level before commercial shipment.
