Why this is a systems problem, not a paperwork problem
A lot of businesses approach EUDR preparation as a documentation exercise: gather the right forms, get suppliers to sign the right declarations, file the right statement. That framing leads to disappointment fairly quickly, because the regulation requires plot-level geolocation data for every parcel of land in a supply chain, verified against deforestation events, kept current as suppliers and land use change, and traceable through every intermediary step to a specific consignment.
For a supply chain with a handful of large estate suppliers, that requirement is manageable with careful documentation. For a supply chain drawing on hundreds or thousands of smallholder farmers, it is a data infrastructure problem. It requires a system: a way to collect data from many sources, verify it, store it so it can be retrieved at consignment level, and keep it accurate as the supply chain changes.
This article sets out how to build that system, treating it as a process with distinct stages rather than a single undertaking. It is informed by the structural difficulties described in the commodity-specific articles on palm oil, cocoa, and timber and wood products, and it complements the EUDR compliance checklist for operators and traders, which sets out what must be done. This article is about how to do it.
Stage 1: Map the supply chain before collecting any data
Before any geolocation data is collected, you need an accurate picture of the supply chain itself. Many businesses discover at this stage that they do not actually know how many suppliers feed into a given product line, because historical procurement was organised around volume and price rather than traceability.
List every tier in the supply chain. From the production plot to the point of placing the product on the EU market, identify every intermediary: collection points, cooperatives, mills, processors, secondary manufacturers, and exporters. Each handover point is somewhere the link to the original plot can be lost if it is not deliberately preserved.
Identify how many suppliers feed into each tier. For estate-based supply chains this may be a small, stable number. For supply chains aggregating from smallholders, this number can run into the hundreds or thousands, and it is often larger than internal estimates suggest once procurement records are actually reviewed.
Determine who controls the data at each tier. A mill or cooperative aggregating from smallholders may be the only party with any existing relationship to the individual farms. Building a compliance system usually means working through these intermediaries rather than around them, because they are often the only practical channel to the original producer.
Flag tiers where no current relationship exists. Some supply chains include sourcing through unlicensed agents or informal intermediaries with no fixed relationship to the buyer. These are the points where building traceability will take the longest, because there is no existing channel to build on.
Stage 2: Build the geolocation data collection process
This is usually the most resource-intensive stage and the one that determines how long the overall system takes to build.
Decide on a collection method appropriate to the supply chain structure. For estate or plantation production, formal survey data or existing land management records may already provide accurate plot boundaries. For smallholder production, this typically means either field-based mobile data collection, where staff visit farms and record coordinates directly, or remote mapping using satellite imagery, where plot boundaries are identified without a site visit. Field collection is more accurate for irregular or unsurveyed plots but is slower and more resource-intensive. Remote mapping is faster to scale but depends on imagery resolution and may struggle with small or visually ambiguous plots.
Engage the intermediaries who hold existing supplier relationships. Where a mill, cooperative, or buying agent already has a relationship with individual farmers, that relationship is usually the most efficient channel for collecting plot data. Building the case for why this matters to the intermediary, not just to the buyer, improves cooperation. Intermediaries who understand that their own continued access to EU-linked buyers depends on this data tend to engage more readily than those who see it purely as an external compliance request.
Set a data standard before collection begins. Decide what level of precision is required (a single point coordinate may be acceptable for a small, regular plot; a polygon boundary may be necessary for an irregular or larger one), what format the data needs to be stored in, and what metadata needs to accompany each record (collection date, method, and the identity of the person or system that collected it). Starting collection without a standard means redoing work later when the format proves insufficient for verification or submission purposes.
Build a process for ongoing collection, not just an initial pass. New suppliers will enter the supply chain. Existing plots will be subdivided, sold, or expanded. A system that only captures data once, at the start, will degrade in accuracy over time. The collection process needs an owner and a recurring cycle, not just a one-off project team.
Stage 3: Build the deforestation verification process
Once geolocation data exists, it needs to be checked against the 31 December 2020 deforestation baseline.
Select a verification approach. Several third-party services now offer automated EUDR verification, cross-referencing submitted coordinates against satellite-based forest cover monitoring data. National monitoring systems, where they meet the required standard, can also be used. Brazil’s PRODES and DETER systems are a notable example of a national monitoring infrastructure that is directly usable for this purpose. Evaluate whether automated verification services or national systems are more appropriate for your sourcing geography, and confirm the data sources each one relies on before committing to it.
Treat verification as continuous, not one-time. A historical batch verification of existing plots is the starting point, but new plots and new suppliers need to be verified as they enter the supply chain, on an ongoing basis rather than in periodic large batches that leave gaps in between.
Build a process for handling verification failures. Some plots will fail verification, either because deforestation is detected after the 2020 baseline or because the coordinate data is not precise enough to produce a reliable result. Decide in advance how these cases are handled: whether the supplier is excluded, whether further investigation is commissioned, and who makes that decision. Without a defined process, verification failures tend to sit unresolved while procurement continues.
Keep records of verification outcomes, not just the final pass or fail. What forest cover data was checked, when, and against what coordinates is itself part of the documentation a competent authority can request. A verification result without a retained audit trail is of limited use if it is later challenged.
Stage 4: Build the legal compliance documentation process
This stage runs in parallel with geolocation and verification work and addresses a different requirement: confirming the commodity was produced legally under the laws of the country of production.
Identify what legal compliance documentation actually exists for your supply chain. This varies significantly by origin and commodity. Land titles, cultivation permits, and environmental approvals may exist in some cases and be informal or absent in others, particularly where land tenure is customary rather than formally titled.
Distinguish between documentation gaps and actual non-compliance. An informal land tenure arrangement is not necessarily evidence of illegality, but it does create a documentation gap that needs to be addressed, typically by working with local authorities, cooperatives, or legal support to establish what evidence can substitute for formal title where formal title does not exist.
Assess whether existing certification or legality frameworks provide a starting point. Schemes such as ISPO, MSPO, FSC, PEFC, or FLEGT licensing were not designed to meet EUDR’s specific requirements and do not substitute for it, but the underlying documentation and spatial data generated by these schemes can reduce the work needed to build EUDR-specific legal compliance records.
Build a substantiation standard, not just a declaration template. A bare statement that production complied with relevant law does not meet the regulation’s standard. The process needs to produce supporting documentation behind each declaration, not just the declaration itself.
Stage 5: Build the supply chain traceability layer
This stage connects the previous three: it is what allows a specific consignment to be traced back to specific verified, legally compliant plots, through whatever intermediary steps exist.
Decide how product identity is preserved through each transformation step. A batch of fresh fruit becomes processed oil. A log becomes sawn timber, then a finished product. Each transformation is a point where the link to the source plot can be lost unless lot tracking, batch identifiers, or equivalent systems are deliberately maintained through the process.
Build documentation requirements into procurement and intake processes, not as an afterthought. Where a mill, processor, or manufacturer is not already recording the origin of what it receives in a way that supports traceability, this requires a change to intake procedures, not just an additional reporting step layered on top of unchanged operations.
Address blending directly. Many supply chains blend material from multiple sources at processing stages, particularly for commodities like cocoa, palm oil, and pulp. Where blending occurs, the traceability system needs to either avoid blending sources with different verification statuses, or maintain mass-balance or segregation systems that preserve the ability to attribute the blended output to its verified sources.
Test the traceability chain end to end before relying on it. Pick a specific consignment and confirm that the documentation trail actually connects it back to verified source plots without gaps. This is the point where systems that look complete on paper often reveal a missing handover record or an unverified intermediary step.
Stage 6: Connect the system to due diligence statement submission
The data infrastructure built in the previous stages exists to support the due diligence statement submitted through the EU’s information system, built on the TRACES NT platform. Following the December 2025 amending regulation (Regulation (EU) 2025/2650), who submits what depends on where your business sits in the supply chain.
Confirm what data format and structure the EU information system requires, and build the internal system’s outputs to match that structure rather than reconciling formats at the point of submission.
Assign clear ownership for the submission step based on your classification. If your business is an operator, the obligation to compile and submit the due diligence statement, or, where eligible, the simplified one-off declaration for micro and small primary operators sourcing from low-risk countries, sits with you directly. If your business is a downstream operator or a trader, you are no longer required to submit your own due diligence statement under the amended regulation. The system you build still needs a process for registering in the EU information system, obtaining the upstream reference number from your supplier, and verifying that the underlying statement was in fact submitted, rather than treating this as resolved by assurance alone.
Build the link between the due diligence statement reference number and the underlying consignment-level data, so that if a competent authority requests the supporting documentation behind a specific statement, it can be retrieved directly rather than reconstructed. For downstream operators and traders, this means the system should preserve the chain of reference numbers back to the original operator submission, not just the most recent one received.
Stage 7: Maintain the system
A system that is built once and left static will degrade. EUDR compliance requires the underlying data to stay current.
Assign ongoing ownership. Someone within the business needs to own the data collection, verification, and documentation process on a continuing basis, not just during an initial build phase.
Set a review cycle for benchmarking classifications. Country and regional risk classifications under the EUDR benchmarking system can change, and a reclassification affects the due diligence burden for sourcing from that origin going forward. The EUDR commodity & country checker shows current risk tiers for all 34 major source countries.
Set a review cycle for supplier and plot data. New suppliers need to be onboarded into the data collection process. Existing plots need periodic reverification, particularly in regions where deforestation risk is active rather than historical.
Build in resilience to regulatory and guidance changes. The European Commission continues to issue guidance and implementing detail as EUDR application progresses. A system built around the current understanding of the requirements should be structured so that it can absorb clarifications without a full rebuild.
What this looks like in practice for different supply chain structures
The stages above apply across commodities, but the effort required at each stage depends heavily on supply chain structure.
For estate or plantation-based supply chains with a small number of large suppliers, Stage 1 mapping is quick, Stage 2 geolocation collection can often draw on existing land management records, and the main effort sits in Stages 5 and 6: building traceability through processing and connecting it to submission.
For smallholder-based supply chains, Stage 1 mapping frequently reveals more suppliers than expected, Stage 2 geolocation collection is the dominant cost and timeline driver, and Stage 4 legal compliance documentation requires the most case-by-case judgment because of informal land tenure. These supply chains should expect the geolocation collection stage to take months at minimum, and treat any deadline that assumes otherwise as unrealistic.
For supply chains involving significant blending or multi-origin inputs, such as paper, pulp, or composite manufactured goods, Stage 5 traceability is the hardest stage, because the system has to either prevent blending of differently verified sources or build mass-balance accounting that can withstand scrutiny.

Verdandi monitors EUDR developments continuously, including country benchmarking classifications and implementing guidance, so the system you build is anchored to the current requirements rather than a snapshot that goes stale. Start for free.
Many regulatory intelligence platforms claim to use official sources. Source anchoring means something specific: every claim traces back to a retrievable official document with a verifiable identifier. Here is what that looks like in practice and why the distinction matters for compliance.
