EUDR Due Diligence for Indonesian Rubber

Updated 2026-11-02 · 4 min read · By the akar.earth specialist team

EUDR due diligence for rubber from Indonesia: tracing smallholder bokar through collectors and crumb rubber factories to segregated, plot-linked bales.

EUDR due diligence for Indonesian rubber means tracing every EU-bound bale from the crumb rubber factory back through traders and village collectors to the smallholder plots where the latex was tapped, then showing those plots were not cleared from forest after 31 December 2020 and are legally held. The factory is the pivot: it must build a registered supply base and keep verified rubber separate through blending and pressing.

The three steps, applied to rubber

Step 1: Map the factory supply base

Crumb rubber factories buy from a wide catchment, often across several districts and sometimes provinces. Start by listing suppliers: large traders, village collectors, farmer groups, auction markets and any estates. Record volumes and sourcing areas for each.

Expect a long tail. A factory may receive from hundreds of collectors, each buying from dozens of farmers. Prioritise the suppliers that deliver most volume and those already organised, such as farmer processing and marketing groups.

Step 2: Register farmers and map plots

Work through collectors and farmer groups. For each farmer, register identity, consent and plots, and map each plot. Rubber plots are often 1 to 3 hectares, so points meet the legal minimum, but polygons help with yield checks and with jungle rubber, where boundaries matter. See rubber geolocation.

Step 3: Screen plots

Satellite screening for rubber is difficult:

• Jungle rubber looks like secondary forest. Global maps often call it forest.
• Tapping panel rotation and old trees do not show from space, but replanting does, as clearing.
• Conversion to oil palm after 2020 removes the plot from rubber supply but is not a rubber deforestation issue.

Screen against forest loss since 2020, then verify flagged plots in the field, recording tree age, tapping status and land use history. See rubber risk assessment and satellite verification.

Step 4: Check legality

Record each plot’s land basis: SHM, SKT or village letter, customary, or social forestry permit. Overlay plots on the forest estate. Old rubber inside the forest estate is common in some districts; check whether a legal route applies before including it. STDB registration, where it exists, is useful evidence. See the legality requirement.

Step 5: Segregate collection and processing

Mass balance is not accepted. For rubber, segregation must survive three points:

1. Collection. Registered farmers’ bokar is bought and transported separately, with collector and farmer records.
2. Factory intake. Verified lots are weighed, tagged and stored apart from other material.
3. Processing. Verified material is cleaned, blended, dried and baled in dedicated runs, with line clearance and batch records linking each bale to intake lots.

Bokar quality varies widely, and factories blend to meet technical grades. Running verified material separately may mean smaller batches or blending only among verified lots. Factories should plan grade mix within the verified supply.

Step 6: Provide the data pack

For each EU shipment: the bale lot IDs, intake lots behind them, farmer and plot lists with geolocation, screening results, legality records, and the chain of custody. Agree the format with the buyer. See due diligence statement.

Step 7: Monitor

Re-screen plots regularly, update registers as farmers join or leave, and track deforestation alerts in sourcing areas near forest frontiers.

Shortening the chain

The most durable fix is to buy more directly from organised farmers. Farmer processing and marketing groups and local auction markets exist in several Sumatran and Kalimantan districts. Working with them gives better quality, better records and a direct relationship. Price premiums for verified, clean bokar help sustain the system.

Linking to rubber agroforestry

Plot data and tree inventories from due diligence support rubber agroforestry carbon programmes that reward farmers for keeping and planting trees. See rubber agroforestry.

Plantation estates in the same factory

Some factories process both estate and smallholder rubber. Estate supply is easier to document and can form the first verified EU volume while smallholder registration expands.

Cost control

Registration and mapping cost more per tonne for rubber than for higher-value commodities. Reuse plot data across buyers, combine mapping with existing extension visits, and focus first on suppliers that deliver most volume.
