Mung Beans from Pakistan: What Southeast Asian Buyers Actually Ask For

Last November I lost a container to a buyer in Ho Chi Minh City. Not because the beans were bad — they were 99.7% pure, machine-cleaned twice, moisture at 11.8%. The problem was color uniformity. Their sprouting facility wanted a specific shade of green, and our lot had maybe 8% beans that were slightly darker. Rejected on arrival.

That taught me something I wish I'd understood three years earlier: mung beans aren't a commodity where "clean and dry" is enough. Southeast Asian buyers, especially the sprouters and the dhal mills, have specifications that go way beyond what a spec sheet usually captures.

So here's what I've learned running Pakistan mung beans export contracts to Vietnam, the Philippines, Indonesia, and Malaysia. Some of it I got wrong at first.

The Grades Nobody Really Agrees On

Pakistan doesn't have a single government-enforced grading system for mung beans the way we do for basmati rice. What you get instead is a de facto commercial grading that varies by exporter, and honestly, that's part of why buyers get burned.

Here's roughly how we grade internally at Acme:

Machine Clean Grade A — 99.5% purity minimum, moisture 12% max, admixture under 0.5%, uniform bright green color, bean size 3.2mm and above. This is what goes to sprouting buyers and premium dhal packers.

Machine Clean Grade B — 99% purity, moisture 12.5%, some size variation allowed, minor color variation acceptable. This works for processors making mung bean flour, paste, or vermicelli.

Fair Average Quality (FAQ) — 98% purity, this is the standard bulk trade grade. Most African and some Middle East buyers work at this level. Southeast Asia usually won't touch it unless the price is really aggressive.

The issue? My Grade A and another exporter's Grade A might not match. I've seen "Grade A" mung beans landed in Manila with 3% split beans. Which is why serious buyers now specify parameters, not grades. Smart move.

What Actually Matters in the Contract

If you're buying green mung beans from a Pakistan supplier and you only write "Grade A, machine cleaned" on your contract, you're leaving money on the table and setting yourself up for a dispute.

The specs I'd insist on if I were buying:

• Moisture: 11-12% max. Anything higher and you'll get mold issues in humid Southeast Asian ports. Cai Mep and Manila both give you problems here.
• Purity: 99% minimum, ideally 99.5%
• Foreign matter: under 0.1% (stones, sticks, mud balls)
• Damaged/broken beans: under 1%
• Weeviled or insect-damaged: under 0.5%
• Bean size: specify millimeters. 3.2mm+ for sprouting, 2.8mm+ acceptable for milling
• Color: this is the one people forget. Ask for a physical sample retention and match against it
• Origin: Punjab mung (usually from Bhakkar, Layyah, Mianwali) tends to be brighter and more uniform than Sindh crop

And fumigation. Always fumigation. Phosphine tablets, 5-7 day exposure minimum, certificate from a licensed operator. Vietnamese and Indonesian customs are strict on live insect findings — I've seen containers held for 3 weeks over one live weevil.

What Southeast Asian Buyers Specifically Want

This is where it gets interesting, because each country's trade has its own personality.

Vietnam is our biggest mung bean market. The sprouting industry there is massive, and they want NM-92 or NM-2006 variety beans, bright green, uniform 3.2-3.8mm, moisture under 12%. They're price-sensitive but they will absolutely reject a container over color inconsistency. Payment is usually LC at sight or 30 days. Ho Chi Minh and Haiphong are the main entry ports.

The Philippines buys mung beans mostly for monggo (the stew) and for pancit ingredients. They're less picky on size uniformity, more focused on cook quality — how quickly the bean softens, whether it holds shape. Manila importers I work with will actually cook a sample before confirming an order. Honestly, more buyers should do this.

Indonesia wants larger beans, 3.5mm+, for their kacang hijau market and traditional sweets. Jakarta buyers pay decent premiums for size but they're tough on moisture — anything over 11.5% and they'll claim.

Malaysia is a smaller volume market but consistent. They tend to buy in mixed containers alongside chickpeas or lentils.

The season matters too. Pakistani mung bean harvest peaks in October-November (Kharif crop) and there's a smaller crop in May-June. Prices are lowest in November-December, and this is when Southeast Asian buyers with storage capacity should be locking in contracts. By March, prices climb 8-15% depending on the year.

The Cleaning Question

Here's the thing about cleaning that most first-time buyers don't understand. "Machine cleaned" in Pakistan can mean anything from a single-pass gravity separator to a full destoner-plus-color-sorter-plus-sizing-grader line.

At our facility in Lahore we run mung beans through:

1. Pre-cleaner (removes sticks, large debris)
2. Destoner (density separation, removes mud balls and stones)
3. Gravity separator (removes lighter damaged beans)
4. Color sorter — this is where the money is spent. A good optical sorter costs $80,000+ and it's the difference between a Grade A and Grade B lot
5. Sizing screens for calibration
6. Final polish and bagging

Not every Pakistani exporter has color sorting capability. If uniform color matters to your end use — and for sprouting it absolutely does — ask your supplier directly whether they have color sorters, what brand, and request a video of your lot being processed. Any legitimate exporter will send it.

I've had buyers ask for that and I appreciate it. It weeds out the traders who are just repackaging beans they bought at Lahore mandi and hoping for the best.

What's your target price range and destination port? Because CFR Ho Chi Minh and CFR Jakarta run about $60-90 per MT apart depending on the shipping line and season, and that changes what grade makes commercial sense for you.
