Market
In Vietnam, mung bean (Vigna radiata) is cultivated as a short-duration legume that can fit into rice-based systems, with documented cultivation in the Mekong Delta. In trade classification, mung beans are commonly referenced under HS 071331 as dried, shelled beans of Vigna radiata/Vigna mungo. For regulated export markets, phytosanitary certification is a core compliance requirement, and Vietnam implemented new phytosanitary certificate formats effective 1 July 2025. The market role is a domestic producer and consumer market with regional export presence, but shipment volumes and destination mix should be validated via official trade statistics sources.
Market RoleDomestic producer and consumer market with export presence (dried pulses)
Domestic RoleCultivated pulse crop used as dry beans and as an input for sprouting/food uses; also used as a rotation/pre-rice crop in Mekong Delta rice systems
Market Growth
SeasonalityIn the Mekong Delta, mung bean can be cultivated in the spring–summer window (e.g., March–June) as a pre-rice crop within intensive rice systems.
Specification
Physical Attributes- Whole, dried mung bean seed with emphasis on uniformity and low defect/insect damage for food-grade lots
- Cleaned and sorted to minimize foreign matter (buyer specification-dependent)
Compositional Metrics- Moisture content specification is commonly used to manage storage stability and reduce mold/insect risk (thresholds are buyer/destination-specific)
Grades- Whole vs split and food-grade vs sowing-grade are common commercial distinctions (as applicable by buyer)
Packaging- Common bulk packaging includes woven polypropylene bags or lined bags (e.g., 25–50 kg) for dried beans; retail packs vary by destination market
Supply Chain
Value Chain- Harvest → drying → threshing → cleaning/sorting → bagging → dry storage (pest control) → containerized export or domestic distribution
Temperature- Ambient dry storage with moisture control to avoid condensation and quality degradation during storage and shipment
Atmosphere Control- Hermetic storage approaches can reduce bruchid damage in stored mung beans where adopted
- Use of liners/desiccants and ventilation practices can help limit moisture uptake in humid conditions
Shelf Life- Shelf-life is primarily limited by moisture uptake and storage-pest infestation risk in dried beans; controls are essential for longer storage periods
Risks
Regulatory Compliance HighPhytosanitary documentation mismatch risk is elevated around Vietnam’s phytosanitary certificate format transition effective 1 July 2025 (including competent-authority name/logo updates); incorrect templates or inconsistent shipment details can trigger border delays or rejection in regulated markets.Use the current Vietnam phytosanitary certificate format; align exporter/importer names, origin, and commodity description with the importing NPPO’s requirements and broker pre-clearance checklist.
Storage Pests MediumStored mung beans are susceptible to bruchid (Callosobruchus spp.) infestation, which can cause significant quality loss during storage and transit if moisture and pest controls are inadequate.Implement robust post-harvest drying and cleaning, monitor infestation, and use appropriate storage controls (e.g., hermetic storage and/or approved treatments as required by destination rules).
Biosecurity MediumHigh-biosecurity destination markets may impose import permits, inspection, or treatment conditions on Vigna spp. consignments; non-compliance can result in hold, treatment orders, or re-export/destruction at destination.Screen destination import conditions early (e.g., via official biosecurity import-condition systems where applicable) and contract treatment/inspection capacity ahead of shipment.
Sustainability- Rice-system integration: mung bean cultivation and residue incorporation has been studied in the Mekong Delta as a practice supporting nutrient cycling in intensive rice systems
FAQ
Which HS code is commonly used for mung bean in international trade classification?HS 071331 is used for dried, shelled beans of the species Vigna radiata (mung bean) or Vigna mungo, whether or not skinned or split.
What changed in Vietnam’s phytosanitary certificate for exports starting in 2025?From 1 July 2025, Vietnam began using new formats for phytosanitary certificates for export and re-export, with updates to the competent authority name and official logo; exporters should use the updated format to avoid document-mismatch delays at import clearance.
Why is storage pest control a key risk for mung beans?Mung beans are susceptible to bruchid (Callosobruchus spp.) infestation during storage, which can rapidly degrade quality if lots are not well dried and protected during storage and shipment.
