Green mung bean

When evaluating quality, prioritize purity levels (ideally ≥99%) and moisture content (should be below 13%) to prevent mold during transit. Look for beans with a bright green, uniform color and a smooth skin, as these indicate freshness. Avoid batches with high percentages of damaged, shriveled, or discolored kernels, which affect the sprouting rate and culinary quality.

Suppliers must provide Phytosanitary Certificates issued by the exporting country's national plant protection organization. Ensure the product meets HACCP (Hazard Analysis and Critical Control Points) and ISO 22000 food safety management standards. For specific markets like the US or EU, verify compliance with Maximum Residue Limits (MRLs) for pesticides and heavy metals as per FDA or EFSA regulations.

If the beans are for sprouting, you must demand a germination rate of ≥95% and ensure they have not been heat-treated. For milling or flour production, the focus shifts to protein content (typically 20-24%) and low foreign matter. For direct retail packaging, aesthetic factors like size uniformity (e.g., 3.0mm, 3.5mm, or 4.0mm) and the absence of 'stone' impurities are critical.

Shiny Skin mung beans are typically preferred for sprouting and direct consumption due to their appealing appearance and faster water absorption. Dull Skin varieties are often used for industrial processing, starch extraction, or traditional medicine, as they can sometimes offer a higher starch yield despite their less vibrant exterior.

Request the use of desiccants and moisture-proof liners inside the containers. For large shipments, ventilated containers are recommended to prevent 'container sweat.' It is highly advisable to hire a third-party inspection agency like SGS or Intertek to perform a Loading Supervision to ensure the goods are dry and pest-free at the time of sealing.

For new suppliers, use Letter of Credit (L/C) or Trade Assurance to protect your funds. Negotiate FOB (Free On Board) terms if you have a reliable freight forwarder who understands food logistics. Always include a clause for weight and quality finality at the port of loading based on a recognized third-party certificate to avoid disputes upon arrival.

Prioritize Audited Suppliers who have undergone on-site verification by independent inspection companies. Check the supplier's Business License and Export Permits specifically for agricultural products. Use the platform's secure payment systems and look for suppliers with a long history of high Trust Points and positive buyer feedback.

Be aware of seasonal quotas and import tariffs that vary by country. Some regions may impose anti-dumping duties or temporary bans based on pest outbreaks. Always verify the Certificate of Origin to benefit from preferential tariff rates under bilateral or multilateral Free Trade Agreements (FTAs).
