Uganda Robusta vs Vietnam Robusta puts the world's largest Robusta producer against the origin whose export trade is built almost entirely on that species. Vietnam's crop for marketing year 2026/27 is forecast at 32.5 million 60 kilogram bags, of which 31.4 million are Robusta, according to the USDA Foreign Agricultural Service post in Ho Chi Minh City. Uganda exported 8.8 million bags of all coffee in the twelve months to April 2026, about 80 percent of it Robusta, on UCDA figures.
The volume gap is wide, and the trade runs both ways. Uganda supplied 10 percent of Vietnam's coffee imports in the first half of marketing year 2025/26, behind Laos, Indonesia and Brazil, on Vietnam Customs data cited in the same USDA report. Both origins sell green Robusta to many of the same roasters. What separates them is crop size, grading, and the price attached to a lot in a given week.
The size of each Robusta crop
Vietnam's Robusta area stands at 644,000 hectares for 2026/27, at an average yield of 2.93 tonnes per hectare. Total coffee area in the country is about 730,000 hectares. Around 30 percent of it is 20 years or older and needs replanting or renewal, according to the Western Highland Agriculture and Forestry Science Institute.
| Marketing year | Robusta | Total coffee |
|---|---|---|
| 2024/25 (estimate) | 28.0 million bags | 29.0 million bags |
| 2025/26 (estimate) | 30.5 million bags | 31.7 million bags |
| 2026/27 (forecast) | 31.4 million bags | 32.5 million bags |
Uganda's entire export crop, Arabica included, is about a quarter of the tonnage Vietnam expects from Robusta alone. Robusta makes up roughly 80 percent of Ugandan export volume, so at the Robusta end the comparison is nearer one bag in five.
Two structural differences sit behind those numbers. Vietnam keeps more of its crop at home: FAS forecasts record domestic consumption of 5 million bags in 2026/27, up from an estimated 4.9 million in 2025/26. Vietnam also ships less of the crop as green bean than its production total suggests. Soluble and roasted coffee made up about 13 percent of its export volume in the period, on Vietnam Coffee and Cocoa Association figures, and FAS forecasts 3.55 million bags of soluble and roasted exports in 2026/27 against 25.4 million bags of green bean.
Uganda Robusta vs Vietnam Robusta on price
Uganda publishes an export grade price every working day. The UCDA series on 15 October 2026 put the three Robusta grades at the levels below, converted at 2,204.62 pounds to the tonne.
| Grade | US cents/lb | USD per tonne |
|---|---|---|
| Robusta Screen 18 | 173.73 | 3,830 |
| Robusta Screen 15 | 168.73 | 3,720 |
| Robusta Screen 12 | 165.73 | 3,654 |
The Vietnamese figures are dated, which matters more than the gap between them. FAS put the average export price for all Vietnamese coffee at USD 5,127 per tonne in the first half of marketing year 2025/26, down 9 percent year on year, with green bean Robusta at USD 4,553 per tonne in March 2026. That window runs from October 2025 to March 2026, before the decline that carried Robusta values lower through the middle of 2026. The Ugandan reading is from October 2026. Hold the two apart by six months and they are not a like for like comparison.
The Vietnamese average needs one adjustment before it is used on a green bean offer. It covers green bean, soluble and roasted shipments together, and processed coffee prices above green bean, so it sits above the green bean market by construction. The March 2026 green bean figure of USD 4,553 per tonne is the one to hold against a Ugandan differential, and even that is half a year away from the Ugandan series.
Inside its own window, Ugandan Robusta moved a long way. Screen 15 fell from 183.57 US cents per pound on 18 July 2026 to 168.73 on 15 October, a drop of 8.1 percent. Screen 18 fell 7.9 percent over the same period. Bugisu AA fell 4.7 percent. The two species fell by different amounts without changing their relationship: the spread between Bugisu AA and Screen 18 was 119.03 cents in mid July and 119.32 cents in mid October.
What matters on the Robusta side is how compressed the ladder has become. Screen 18 carried a 5 cent premium over Screen 15 on 15 October, and Screen 15 carried 3 cents over Screen 12. On a 60 kilogram bag that is USD 7 and USD 4. Freight, timing and payment terms outweigh a screen choice that narrow.
Grading and how each lot is sold
Uganda grades Robusta by screen, measured in 64ths of an inch, and caps defects per 300 grams. Screen 18 and Screen 15 lots are graded on the UCDA auction floor, where the result is public. Direct export contracts carry the rest of the crop, and the buyer there is agreeing a screen range rather than a floor result. The full ladder, including the Arabica names, is set out in our guide to Uganda coffee grades.
Vietnamese offer sheets name a grade and a screen, and the country has spent the past five years on quality. FAS describes a Specialty Coffee Program run by the Ministry of Agriculture and Environment since 2021, built around better farming practice, selective harvesting and post harvest processing, and records the aim as moving from volume alone toward higher quality and more traceable supply. A Vietnamese offer is not always a commodity quote.
Certification, traceability and the EUDR file
About 40 percent of Vietnam's coffee area held sustainability certification as of 2025, covering Rainforest Alliance, Fairtrade, 4C and UTZ schemes. More than 600,000 smallholder households grow the crop, and FAS reports the agriculture ministry and exporting companies working to meet EU Deforestation Regulation requirements.
Uganda's route to a compliant lot runs through cooperatives and UCDA-licensed exporters, with a national traceability system behind the licensing. What a European buyer has to collect and retain is covered in our EUDR compliance guide, and the steps for buying direct from a cooperative are in the cooperative sourcing guide.
How buyers split the two origins
Volume leads the decision for most blenders. Vietnam's green bean exports are forecast at 25.4 million bags in 2026/27, and supply at that scale is rarely the constraint. A roaster filling a container of commercial Robusta on a screen and grade specification can find it without much searching.
Uganda fits a different brief. The daily UCDA series gives a published reference for each screen grade before a lot is priced, which shortens the argument about where the market sits. Robusta from the Lake Victoria basin and the central districts carries the body and crema that espresso formulators work with, and the same logistics corridor also moves Arabica. Background on where each crop grows is in the region guides, and the variety profiles cover what is planted and how it cups. The processing guide explains how washed, honey and natural preparation change what a given screen delivers in the cup, and the buyer's guide covers registration, contracting and shipping.
One point of overlap is easy to miss. Vietnam took 10 percent of its coffee imports from Uganda in the first half of 2025/26, alongside supply from Laos, Indonesia and Brazil, and a large share of those imports feed Vietnamese processing plants. The two origins meet inside the same supply chain rather than sitting as clean substitutes. A buyer replacing a Ugandan parcel with a Vietnamese one has to check the screen, the defect ceiling and the preparation, because the country name does not carry the specification.
Uganda Robusta vs Vietnam Robusta resolves on what the offer has to guarantee, not on which country grows more coffee. Vietnam brings a 31.4 million bag Robusta crop, 25.4 million bags of annual green bean exports, and certification across about 40 percent of its area. Uganda brings a published price for every Robusta screen grade, a crop that is 80 percent Robusta by export volume, and a short chain from cooperative to container. Price either origin against the date on the quote, write the screen and defect ceiling into the contract, and the decision settles on the specification rather than the flag on the bag.
