Vietnam is one of the world’s largest exporters of wood products to the European Union, making compliance with the EU Deforestation Regulation increasingly critical for timber exporters, furniture manufacturers, plywood producers, and wood processing companies. At the center of EUDR compliance lies precise geolocation: GPS polygon mapping of the forest plots where timber was harvested. Geo mapping for wood exporters in Vietnam is rapidly becoming a foundational capability for validating origin, demonstrating legality, and maintaining uninterrupted access to EU markets. This guide walks through the key requirements and operational considerations for achieving compliance at scale. 

What the EU Deforestation Regulation Requires for Vietnam Wood Exporters 

Regulation (EU) 2023/1115, commonly referred to as EUDR, entered into force on June 29, 2023, with mandatory compliance obligations beginning in late 2024. The regulation targets seven high-risk commodities linked to deforestation and forest degradation, including wood and timber products. 

For Vietnam’s export-driven wood sector, EUDR introduces a major shift in how sourcing, traceability, and legality must be documented across supply chains. 

Core Legal Obligations 

Operators and traders placing wood or wood-derived products on the EU market must demonstrate three core requirements before products can enter the EU: 

• No deforestation: Timber must not originate from land deforested after December 31, 2020. 

• Legal compliance: The wood must be harvested and produced in accordance with the laws of the country of production, including forestry regulations, land-use rights, labor laws, and environmental legislation. 

• Due diligence: Companies must conduct and document due diligence through a Due Diligence Statement (DDS) submitted to the EU Information System. 

The Geolocation Mandate 

Article 9 of EUDR makes geolocation mandatory for timber supply chains. Operators must provide precise geographic coordinates of the forest plots where the wood was harvested, typically through GPS polygon mapping. 

Coordinate type	GPS polygons (lat/long pairs forming a closed boundary)
Accuracy standard	Parcel-level, sufficient to verify against satellite forest-cover data
Cut-off date	December 31, 2020 (forest cover must be intact at this date)
Format requirement	GeoJSON or compatible geospatial format
Linked documentation	Due diligence statement referencing coordinates
Submission system	EU TRACES / dedicated EUDR IT platform

For Vietnam wood exporters, this means: 

• Mapping forest plots and sourcing areas accurately 

• Collecting polygon-level geolocation data 

• Validating GeoJSON formats before submission 

• Linking harvested timber to traceable sourcing records 

• Maintaining auditable traceability documentation 

Key Data Requirements Include: 

• GPS polygon coordinates of harvest areas 

• Supplier and forest owner information 

• Species and product details 

• Harvest dates and sourcing documentation 

• Traceability linkage across processing and export workflows 

• Deforestation risk verification 

As EU buyers strengthen sourcing requirements, geospatial traceability is becoming essential not just for compliance but for maintaining long-term market access and buyer confidence. 

Vietnam Wood Exports 

Vietnam’s wood and wood products exports rebounded strongly in 2025, reaching US$17.2 billion, up almost 5.7% from 2024 and setting a new record for the sector. The industry still fell slightly short of its US$18 billion target, but the result confirms Vietnam’s position as one of the world’s leading wood-exporting economies. 

Data Snapshot 

Vietnam exported about US$17.2 billion of wood and wood products in 2025, with the United States remaining the largest market at US$9.46 billion, or roughly 55% of total export turnover. Japan became the second-largest market, rising more than 23% to US$2.153 billion, while China followed closely at US$2.086 billion. In 2023, the sector had fallen to US$13.4 billion, down 16.5% year on year, which shows how quickly the industry recovered in 2025. 

Indicator	Time Period	Value
Total Wood Exports	2023	US$13.4 Billion
Total Wood & Wood Products Exports	2025	US$17.2 Billion
Year-on-Year Growth	2025	~5.7%
Exports to the US Market	2025	US$9.46 Billion
Exports to the Japan Market	2025	US$2.153 Billion
Exports to the China Market	2025	US$2.086 Billion

Market Insights 

The export rebound was helped by improving demand in major destination markets and by Vietnam’s strong position in furniture and processed wood products. In 2023, the industry had been hit by weak global consumption, especially in the US and EU, but 2025 showed that Vietnamese exporters could recover quickly when orders returned. The US, Japan, and China together accounted for nearly 80% of total export value, which means the sector is highly competitive but also concentrated. 

The biggest trend is that Vietnam’s wood industry is no longer just a low-cost manufacturing base; it is becoming a high-value export platform with global scale. Growth in Japan and recovery in the US suggest buyers are returning to Vietnamese suppliers for both price competitiveness and supply reliability. At the same time, dependence on three large markets leaves the sector exposed to trade policy shifts, housing cycles, and sustainability requirements. 

Vietnam matters because it has built a globally competitive wood-processing industry that can still expand through value-added furniture, engineered wood, and certified sustainable products. For exporters, the key opportunity is to move further up the value chain while strengthening traceability and compliance with forest legality and sustainability rules. For buyers, Vietnam offers scale, speed, and product diversity, but the market remains sensitive to demand shocks in the US and Japan.

Why Geolocation (GPS Polygons) Is Mandatory for Vietnam Wood Exporters 

The EU Deforestation Regulation GPS polygon requirement is not just a documentation exercise it is the technical foundation of the EU’s deforestation verification framework. Without accurate forest plot boundaries, wood supply chains cannot demonstrate compliance. 

The Satellite Verification Pipeline 

The EU and third-party verification systems rely heavily on satellite imagery—including Copernicus, ESA Sentinel datasets, and Global Forest Watch—to assess forest cover changes at the parcel level. This process depends entirely on accurate polygon mapping. 

The verification workflow typically follows these steps: 

1. Exporter submits GPS polygon coordinates for the forest harvesting plot. 

2. Coordinates are overlaid against historical satellite imagery dating back to December 31, 2020. 

3. Algorithms assess whether the area was forested before the EUDR cut-off date. 

4. Any post-2020 deforestation activity within the polygon can trigger a compliance flag. 

5. Non-compliant timber shipments may be restricted from entering the EU market. 

Why GPS Points Are Not Enough 

Traditional timber traceability systems often relied on a single GPS point or approximate location reference. Under EUDR, this is no longer sufficient. 

Polygon mapping is mandatory because: 

• Forest harvesting areas are often irregular and fragmented 

• A single point cannot accurately define harvest boundaries 

• Satellite systems require area-level calculations to assess canopy loss 

• Polygon data supports traceability aggregation across multiple forest plots and suppliers 

Regulatory Note 

For smaller forest plots, operators must still provide a closed polygon with multiple coordinate pairs. Larger harvesting areas must accurately reflect the real forest boundary and not approximate square bounding boxes.

Challenges in Vietnam Wood Sourcing 

Vietnam’s wood and timber supply chain presents significant operational and traceability challenges for EUDR compliance. 

Fragmented Supplier Ecosystem 

Vietnam’s timber sector involves: 

• Smallholder forest owners 

• Plantation growers 

• Aggregators 

• Sawmills 

• Processors 

• Furniture manufacturers 

This creates major traceability complexity across sourcing networks. 

Common challenges include: 

• Incomplete land ownership documentation 

• Fragmented forest plots across multiple regions 

• Limited digital mapping infrastructure 

• Supplier data inconsistency 

• Complex intermediary networks before export processing 

Geographic & Infrastructure Constraints 

Key timber-producing regions such as: 

• Binh Duong 

• Dong Nai 

• Quang Tri 

• Gia Lai 

• Dak Lak 

• Central Highlands regions 

often include remote sourcing areas with: 

• Limited mobile connectivity 

• Inconsistent GIS data quality 

• Difficult terrain for field verification 

• Forest-edge sourcing complexities 

Traceability Gaps Across Processing Networks 

Vietnam’s wood processing ecosystem relies heavily on: 

• Small and medium sawmills 

• Aggregators 

• Multi-tier timber sourcing networks 

As timber moves through processing and manufacturing layers, maintaining traceability continuity becomes significantly more difficult. 

Step-by-Step Geo Mapping Process for Vietnam Wood Exporters 

Step 1: Supplier & Forest Owner Onboarding 

Before mapping begins, exporters should: 

• Register supplier identity information 

• Verify land-use and harvesting rights 

• Obtain consent for geolocation collection 

• Validate supplier legality documentation 

• Explain EUDR implications clearly to suppliers 

Step 2: Forest Plot Boundary Mapping 

Field teams use GPS-enabled devices or GIS applications to capture harvesting plot polygons. 

Best practices include: 

• Confirm GPS accuracy before mapping 

• Walk the actual forest boundary 

• Capture coordinates at regular intervals 

• Close the polygon correctly 

1. Capture photos with geotag metadata 

2. Record species and harvest details 

Step 3: Field-Level Validation 

Before leaving the site, field validation should confirm: 

• Polygon closure accuracy 

• No self-intersecting polygons 

• Area consistency against declared records 

• Visual alignment with satellite basemaps 

Step 4: Deforestation Risk Assessment 

Captured polygons should then be screened against: 

• Global Forest Watch 

• Copernicus datasets 

• National forest cover maps 

• EU deforestation risk datasets (where applicable) 

Plots showing post-2020 deforestation risk may require remediation or exclusion from EU-bound sourcing. 

Step 5: GeoJSON File Generation 

Validated polygon data must then be exported into: 

• RFC 7946-compliant GeoJSON format 

• Structured geospatial records suitable for DDS workflows 

• Audit-ready traceability documentation 

Proper GeoJSON validation is critical before submission to avoid DDS rejection or shipment delays. 

Geometry type	Polygon (Feature)
Coordinate system	WGS 84 (EPSG:4326)  mandatory
Coordinate order	Longitude first, then Latitude (per GeoJSON spec)
Winding order	Exterior ring: counter-clockwise
Properties	farmer_id, plot_id, area_ha, crop_type, country, region
Encoding	UTF-8
Validation tool	geojsonlint.com, QGIS geometry validator, or Turf.js

Step 6: Due Diligence Statement Submission 

The final stage connects GeoJSON polygon data and timber traceability records to an official Due Diligence Statement (DDS) submitted through the EU Information System or TRACES-linked workflows. 

For Vietnam wood exporters, this process typically involves: 

• Compiling all validated GeoJSON polygons associated with the timber harvest areas for a given export batch. 

• Attaching supporting compliance documentation, including land-use permits, harvesting approvals, legality records, and forest-cover verification results. 

• Completing the DDS workflow while referencing applicable HS codes for wood and timber products (for example plywood, sawn timber, veneer, furniture, or wood panels). 

• Submitting the DDS through the EU Information System and retaining the generated reference number for customs and shipment documentation. 

• Maintaining traceability and compliance records for a minimum of 5 years in accordance with Article 10 of the EU Deforestation Regulation. 

Geo mapping for wood exporters in Vietnam becomes significantly easier with TraceX EUDR solutions, enabling accurate forest polygon mapping, GeoJSON validation, supplier traceability, and end-to-end DDS compliance management across complex timber supply chains. 

Common Errors in GeoJSON / Polygon Mapping 

Data quality failures at the polygon level are the single most common reason EUDR submissions are flagged for review or rejected. Field teams and data managers should be trained to identify and fix the following errors: 

Error Type	Description	Impact	Fix
Self-Intersection	Polygon boundary crosses itself, creating a ‘bowtie’ shape. Occurs when field agent reverses direction while walking.	Fails GeoJSON validation; geometry engine cannot compute area.	Re-walk boundary; use QGIS Fix Geometries tool.
Unclosed Ring	First and last coordinate pair do not match. Polygon ring is not closed.	GeoJSON spec violation; most validators reject outright.	Append first coordinate to end of ring, or use auto-close in KoboToolbox.
Wrong CRS	Coordinates recorded in VN-2000 (Vietnam national projection) or UTM instead of WGS 84.	Coordinates displaced by hundreds of meters from true location.	Reproject to EPSG:4326 using QGIS or GeoPandas.
Reversed Winding Order	Exterior ring wound clockwise instead of counter-clockwise per RFC 7946.	Some parsers treat interior of polygon as exterior; area inversion.	Reverse coordinate array; QGIS ‘Rewind Polygons’ tool.
Coordinate Swap	Latitude and longitude values transposed (lat first, instead of GeoJSON spec’s lon first).	Plot placed in wrong hemisphere or ocean; immediate deforestation false-alarm.	Validate first coordinate: Vietnam lon ≈ 102–109°E; lat ≈ 8–23°N.
Spike Artefacts	One or more vertices are outliers caused by GNSS signal bounce under canopy.	Polygon area inflated; boundary bleeds into adjacent plots.	Remove outlier points; apply Douglas-Peucker simplification at 1m tolerance.
Duplicate Polygons	Same farm submitted twice with different farmer_id due to aggregator duplication.	Inflated area records; compliance review flags double-counting.	Spatial deduplication using PostGIS ST_Equals or Turf.js booleanEqual.
Overly Simplified Polygon	Only 3 or 4 vertices used for complex, irregularly shaped plots.	True boundary not captured; adjacent deforested land may be excluded or included.	Minimum 6–8 vertices for plots with non-linear edges; re-survey if needed.
