What Sits Between a $0.84 Durian and a $76,000 Export Container

A farmer in Vietnam may sell durian for around VND 21,000–22,000 per kilogram — roughly $0.81–0.84/kg. Further down the chain, a 40-foot container carrying more than 20 tonnes of durian can be worth over VND 2 billion — around $76,700. Put those two numbers next to each other and the obvious question appears: what exactly happens between the farm and the export container?

That was the question I wanted to understand. I have lived in Vietnam since 2016 and work with food products and supply chains from Asia for international markets, so I was much more interested in the commercial mechanics than in whether durian smells unusual or whether one premium variety tastes better than another. I wanted to understand where cost accumulates, where value is added, how quality is judged, and where the risks sit before the fruit reaches a trader, supermarket or export container.

I discussed this in Ho Chi Minh City with Lam Quang Chi, 26, from Krong Pak District in Dak Lak Province. Chi has worked with durian since his teenage years. His family grows it, and his own experience includes harvesting, sorting large commercial batches, working with supply chains connected to Chinese buyers, and later moving into distribution and retail. The figures below come from Chi’s own orchard and practical experience and should be read as his estimates rather than official averages for Vietnam’s entire durian industry.

The First Cost Is Time

Chi’s family did not originally build its farm around durian. They grew coffee and Booth avocados, but according to him the avocado crop was not attractive enough economically because yields were relatively low and prices were disappointing. In 2015, the family removed around 200 avocado trees and began converting the land to durian. Today they have roughly 200 durian trees on about 1.2 hectares.

The first economic problem appears immediately: a durian orchard requires years of spending before it starts producing meaningful revenue. A tree may begin producing fruit around the fourth year, but even then the farmer may decide not to keep the crop. If the tree is still weak, carrying fruit can slow its development, and Chi says fruit from very young trees may also be excessively large, with thick skin and relatively little flesh.

In that situation, farmers remove the young fruit and give the tree another year to develop. The first proper harvest may therefore come only in year five. During those four or five years, the orchard is already consuming money through irrigation, fertilizer, plant protection, weeding, labor and general maintenance.

The first harvest still does not mean the orchard is mature. Chi says production begins to stabilize around the eighth year, while by roughly years ten to twelve the trees become much more consistent. The fruit changes as well: on mature trees the skin tends to become thinner, there is more flesh, and the fruit becomes more balanced in size and shape. A retail price on a supermarket shelf says nothing about this waiting period.

A Cheap Seedling Does Not Mean a Cheap Orchard

The planting material itself is relatively inexpensive. Chi mentioned examples of seedlings costing roughly $1.50, $3 and $4.60, depending on size and quality. The real cost begins after planting.

For a young orchard of around one hectare, he estimates annual operating expenses at roughly $3,800. For his family’s current orchard, annual spending is above $7,700, while a mature, intensively managed orchard may require approximately $9,600–11,500 per year. Those costs include fertilizer, crop-protection products, weeding and labor, and they fluctuate with input prices.

Chi uses around 100 trees per hectare as a general reference for a conventional planting pattern, but his own family has more than 200 trees on about 1.2 hectares. As the trees mature and their canopies expand, competition for light and space becomes more important. Doubling the number of trees therefore does not automatically double the crop; age, spacing, soil conditions and management all change the result.

Not Every Tree Reaches Maturity

Chi estimates that a mature durian tree may commonly produce around 50 to 100 fruits per season. With an average fruit weight of around three kilograms, that translates into approximately 150–300 kilograms per tree. Old, large trees can produce much more, and during our interview he mentioned individual mature trees capable of reaching around 800 kilograms in a season.

Those figures describe the trees that survived. In his family’s earlier experience, two or three seedlings out of every ten could die, especially during the first several years. Failed trees have to be replaced, and each replacement starts its own four- or five-year journey toward the first meaningful crop.

The loss is therefore not just the price of a seedling. It is also lost time, maintenance and productive capacity that has to be rebuilt.

Weather Can Change Both Yield and Grade

Weather affects durian at several different stages. During flowering, heavy rain can damage flowers and reduce the number of fruits that eventually develop. Months later, rain shortly before harvest creates a different problem: Chi says the flesh can become paler and the flavor more watery.

Farmers may therefore wait for a sunny day after rainfall before cutting the fruit, but waiting has its limits. Once a durian reaches a certain level of maturity, it can fall naturally. During peak season, Chi says his family may collect around 100 kilograms per day of fruit that has already fallen.

Later in the interview, we opened a Ri6 and one fruit had exactly the watery characteristic he had described earlier. That connected the farming decision directly with the product in front of us. Weather does not simply decide how many kilograms an orchard produces; it can also influence which commercial grade those kilograms eventually fall into.

One Season Means Several Harvest Decisions

Dak Lak generally has one main durian season per year, roughly from July into November or December depending on the area, but that does not mean one harvest. Flowering happens in several waves, so fruit reaches maturity at different times.

Chi says a farmer may go through the orchard three or four times during a season, sometimes five, with around seven to ten days between rounds. Each pass creates another decision about what is ready to cut, what should remain on the tree and what quality is likely to be available.

After the final harvest, the next production cycle begins almost immediately with tree recovery, irrigation, fertilization and preparation for the next flowering period. The orchard therefore continues to require inputs regardless of whether the market is paying a high or low price that season.

Then the Fruit Leaves the Farm

Chi spent several seasons in a team handling durian for partners connected to Chinese buyers. During peak periods, more than 10 tonnes per day could pass through his hands. The team usually consisted of around eight to ten people who harvested, received and sorted the fruit, while local workers handled movement inside the orchards.

This is where the fruit begins to separate into different commercial outcomes. A buyer may purchase an entire orchard at one average price and perform the grading afterward. The farm-gate price is therefore not the final value of every fruit in the batch; it is the starting point before the lot is divided by variety, size, condition and quality.

Harvesting labor alone may add around $0.12/kg, according to Chi. After that come sorting, rejected fruit, packaging, domestic transport and export handling. The original farm-gate number has already started changing before the product reaches an international border.

China Changes the Risk Structure

For the supply chain Chi works with, China is the dominant export market. That obviously affects demand and price, but the more important effect is how it changes the risk structure of the business.

A farmer can influence irrigation, fertilization and orchard management, but cannot control whether the end market is buying aggressively, whether import requirements become stricter or whether a shipment encounters a compliance problem. Durian intended for export is connected to registered growing areas with identification codes, creating traceability between the fruit and its source.

That code has commercial value because it gives an orchard access to an export chain. It can also become a liability.

Chi specifically discussed cadmium, a heavy metal for which excessive levels can create a compliance issue. He mentioned fertilizer and contaminated water as possible sources from a farmer’s perspective; that should not be treated as a laboratory conclusion about the cause of contamination.

The commercial chain is easier to understand. A container may be inspected, a box chosen, a fruit opened and the product checked. If the shipment does not meet the importing market’s requirements, the consequence does not stop at customs. The exporter may lose money, the buyer may refuse the shipment, a trader may stop buying from that area, and a problem linked to a particular growing-area code can affect other business connected with the same source.

That is why I see the growing-area code as more than an administrative detail. Once export becomes the objective, durian becomes a business of traceability and market access as much as farming.

The $0.84 Price Is Only the Beginning

During our interview, Chi quoted a local buying price of around VND 21,000–22,000/kg — approximately $0.81–0.84/kg. Further down the chain, a 40-foot container carrying more than 20 tonnes may contain over VND 2 billion — around $76,700 — worth of durian.

It would be easy to use those two figures to imply that the middle of the chain is simply collecting an enormous margin. The problem is that the interview does not support that conclusion. The batch has already been graded, some fruit may have been rejected, different varieties carry different values, and labor, packaging, transport and export costs have been added.

This is also where the limits of this particular interview matter. Chi can explain the farm, harvesting, sorting and part of the buyer relationship from direct experience. He does not provide a full landed-cost calculation for an importer in China, nor the complete economics of the exporter and trader between the Vietnamese orchard and the final Chinese customer. That middle section of the chain deserves a separate conversation with an exporter or importer rather than an invented calculation based on two extreme prices.

Variety Is a Pricing Factor, Not Just a Taste Preference

This becomes obvious when the varieties themselves are compared. During the interview, Chi showed Ri6, Chuồng Bò, Musang King and Black Thorn. Ri6 and Chuồng Bò are Vietnamese varieties; Musang King and Black Thorn originated in Malaysia, although the fruits we tried were grown in Vietnam.

The differences are visible after opening — Black Thorn has more orange-colored flesh, while Musang King is a deeper yellow — but the commercial distinction is even clearer in the prices Chi used when explaining his family’s economics. Ten tonnes of Ri6 at around $0.96–1.00/kg would generate roughly $9,600–10,000. In the same example, a more expensive Thai-origin variety at around $3.26/kg would represent approximately $32,600 for the same ten tonnes.

That is more than a threefold difference in value before we even start talking about final retail prices. Variety therefore affects the economics at the orchard level itself, not only the way consumers describe flavor.

Ri6 is a useful example because it does not need to be the most expensive variety to be commercially important. It originated in Ben Tre in the Mekong Delta and later spread widely through Vietnam, becoming one of the country’s important commercial and export varieties alongside Dona.

Quality Is Decided Before the Box Is Closed

The next commercial decision happens before the fruit ever reaches a warehouse. Somebody has to decide whether it is ready to cut.

Chi checks maturity partly by tapping the fruit with a knife, listening to the sound and feeling the vibration through the tool. He also showed a simpler physical test: press two neighboring spikes toward each other. On a mature fruit they flex slightly; on an immature fruit they remain stiff.

Seen only as a market trick, this can look like a consumer tip. In a commercial chain, the same judgment determines when the fruit leaves the tree. Cut it too early and it may not develop correctly; leave it too long and it may fall. That decision affects quality, shelf life, grading and the condition in which the fruit eventually reaches the buyer.

Harvest Maturity Is Not Eating Ripeness

Chuồng Bò illustrates another complication. Chi explained that a fruit can be mature enough to harvest but still require approximately five to seven days before reaching eating ripeness.

That period matters because the fruit is already moving through the supply chain while its condition continues to change. A durian that needs several days to ripen behaves differently from one intended for immediate consumption. Transit time, destination and storage conditions therefore become part of the same decision about when to cut the fruit.

Storage Extends the Commercial Window

At Chi’s shop, opened durian flesh is kept at approximately 6–8°C. Under good conditions, he says it can remain suitable for around seven to ten days, sometimes longer. They use containers made from sugarcane fiber rather than conventional plastic packaging.

For longer storage, they freeze it. Chi prefers the weakest freezing setting — effectively the warmest freezer temperature — so the flesh remains relatively soft instead of becoming completely solid. We tried it during the interview, and the texture was much closer to ice cream: softer, creamier and with a noticeably milky character.

For a consumer, this simply means a large durian does not have to be eaten immediately. For a seller, it also extends the window in which the product can be stored and served without treating every opened fruit as an immediate write-off.

A Good Year Can Look Very Good

Chi says his family can harvest more than 20 tonnes in a season. For a mature orchard of around 100 trees, he uses roughly 20–25 tonnes as a reference point and around 30 tonnes for a particularly strong crop.

At an average selling price of approximately $2.30–2.69/kg, a 30-tonne crop would generate around $69,000–80,600 in revenue. At first glance, that is the kind of number that makes durian farming look extremely attractive.

Before that figure exists, the farmer has already waited years for the trees to mature, replaced dead seedlings, paid for repeated seasons of orchard maintenance and carried weather risk throughout the process.

Then Ri6 Falls to VND 16,000

Chi also remembers a bad period when Ri6 sold for around VND 16,000/kg — approximately $0.61/kg. Nothing on the cost side disappears when that happens. Fertilizer is still required, workers still need to be paid, irrigation continues, and diseases and pests still have to be controlled.

A mature orchard cannot simply be paused for a year because the selling price is unattractive. The farmer has already committed to the crop years earlier, and the trees continue to require attention regardless of where the market happens to be that season.

The Final Cost Is Harder to Put Into a Spreadsheet

Near the end of the interview, I asked Chi what he disliked most about the durian business. By that point we had discussed prices, yields, China, export requirements, varieties and storage.

His answer was about health.

He described years of irrigation, fertilizer application, plant protection, flowering management, orchard maintenance and harvesting. Then he talked about his parents and the physical cost of doing this work year after year. In his words, they sacrificed their health so that the family could have a better life.

When we look at a $0.84 farm-gate price or a $76,700 container, it is easy to reduce the entire chain to a spreadsheet. But before any of those numbers exist, somebody has already spent years maintaining the trees that produced the fruit.

What the Price Gap Actually Tells Us

The distance between $0.84/kg at the farm and a $76,700 export container does not point to one simple explanation. It shows how misleading it is to treat durian as a single product with one price.

The fruit changes value because the business around it changes. Time matters before the first harvest. Some trees never reach maturity. Weather can reduce both yield and grade. Varieties can differ several times in price within the same orchard. Harvest timing influences quality. Grading separates the batch. Logistics and handling add costs. Export introduces traceability and compliance risk, while the economics of exporters, traders and landed cost in China sit further down the chain and require their own data.

The part I find most important, however, comes before all of that. A farmer plants a durian tree, spends money on it for years, and only later discovers what the market is willing to pay for the crop.
