Trase's September 2026 Coffee Supply-Chain Map: What It Reveals—and Cannot Prove About a Lot

September 19, 2026. Dataset publication: September 2026; underlying trade year: 2020.

The coffee industry has a new public way to examine connections between producing countries, trading companies and destination markets. Trase released coffee supply-chain mapping in early September 2026, making parts of international trade more visible. The development matters to importers and emerging origins such as Cambodia, but its scope needs care. A historical trader-flow map is not a certificate proving that a particular bag of Cambodian coffee came from a specific farm.

What Trase released

Trase, a partnership involving the Stockholm Environment Institute and Global Canopy, published an insight on September 1 describing a dataset connecting producing countries and subnational areas with exporters, importers and destination markets. The associated methods publication identifies 2020 as the mapped trade year and describes using trade statistics and shipment information from ten producing countries.

The publication date and the data year are different. This analysis became public in September 2026, but its mapped flows represent 2020. Its percentages must not be repeated as observed 2026 market shares. Every data-driven coffee article should disclose the population and period represented by a headline statistic.

What the concentration figures show

Trase's September 1 press release says the ten largest traders handled 35% of coffee exports from the ten examined producer countries; the top thirty handled 55%. It identifies Brazil and Vietnam as particularly large producers in that mapped system, representing 32% and 18% of global exports respectively, and the European Union as a major import destination.

These are research findings about aggregate trading structure. They are not measures of Cambodia's current exporter concentration, proof that any individual trader meets sustainability requirements or confirmation that its buyers want OCC coffee. Large firms' procurement systems may affect many supplier relationships, but demand for a particular product still needs direct evidence.

Why a small origin must read a global map carefully

Cambodia's coffee trade is smaller than trade from the countries central to most global data visualizations. A map built around major exporters cannot automatically represent every Cambodian producer, collector, processor or shipping relationship. Not appearing prominently in a chart does not mean a business has no product or cannot deliver quality.

Instead, the map can help a company understand the wider supply system while encouraging better records closer to home. International trade architecture and a small supplier's actual product are different levels of information. A buyer needs both context and proof of what is being offered.

Origin evidence comes in layers

A label may state Cambodia as agricultural origin. More detailed documentation may identify Mondulkiri, a collection area, a farmer group or a processing site. A commercial lot code can then connect cherry intake with processing, drying, storage, milling, packaging and shipment. Marketing language alone cannot establish every link in this chain.

A public trade map may identify an exporter and destination, but it cannot automatically prove which cherries entered a bag during a particular harvest. That requires primary lot records, controlled identity and a process for handling aggregation. The appropriate question is: exactly which step does this source verify?

What about EUDR?

The European Union's deforestation regulation covers coffee and specified products. The European Commission lists December 30, 2026 for large and medium operators and June 30, 2027 for micro and small operators, with an earlier exception for certain businesses under the EU Timber Regulation. Obligations depend on the particular product and operator's role.

A trader's appearance in a 2020 dataset is not a due-diligence certificate. Relevant EU operators need transaction-specific records, including production-plot geolocation and information addressing deforestation and legality. Public maps may help with risk research but do not substitute for an individual consignment's compliance evidence. For legal obligations, consult current European Commission guidance and qualified advice.

What a buyer should request

Begin with exact product identity: green or roasted coffee, species, origin, harvest and proposed volume. Ask for documented producer and processor details, collection records, lot codes, processing and storage information, and a sample that represents inventory. Physical and sensory results should be dated and linked to the offered coffee. Establish the commercial delivery responsibilities separately.

Where EU rules apply, clarify each party's legal role and the required information for that transaction. A supplier working with many smallholders can still provide useful traceability if its aggregation, separation and recordkeeping system is transparent. A single-farm photo with no link to the saleable lot is not a substitute.

Five conclusions the data cannot support

The 35% figure is not Cambodia's current exporter market share. A trading-company name is not proof of a specific buyer's purchasing policy. Historical production geography is not a present-day map of every plot. Sustainability risk estimates are not individual farm inspections or cupping certificates. Finally, Trase's publication does not amount to an endorsement of OCC or another Cambodian coffee supplier.

Recognizing these boundaries protects the real value of the research. Aggregate trade visibility can inform better questions precisely because it does not pretend to answer everything.

Build a clearer buyer journey

Someone searching for coffee traceability should receive a direct explanation of what a source can verify, its year and its limitations. The next page should help evaluate a supplier, rather than displaying an unrelated sales claim. For OCC, a suitable path runs from trade analysis to Cambodian coffee supplier evaluation and, when appropriate, wholesale enquiry.

This approach helps readers who need technical specifications, farm-level information or available quantities identify those requirements before making contact. It also gives producers a practical list of records that could make future lots easier to assess.

A three-level evidence model

At market level, use dated published datasets and note their coverage. At company level, look for documents establishing each participant's actual role. At lot level, inspect harvest and processing records, sample identity, current inventory, physical evaluation, sensory evidence and shipment documents. Never promote a conclusion drawn from one level into a claim about another.

Faq

Does the new dataset track 2026 exports? No. Trase's published methods identify a 2020 trade baseline.

Can it prove the cupping score of Cambodian Robusta? No. A specific representative sample and stated assessment method are required.

Does a trader map replace EUDR plot data? No. Applicable due diligence requires separate transaction-specific evidence.

Does it establish demand for OCC? No. The research maps wider trade flows, not individual purchase enquiries.

OCC takeaway

The advance is better visibility into global supply-chain structure. Cambodia's next task is more granular: connect one named coffee from verified production to the product offered to a buyer. Learn more through Cambodian supplier evaluation and Wholesale Coffee Supply.
