Note: May 27, 2026 – This is an update to the May 26, 2026 article: Indonesia’s Palm Oil Export Crackdown: Trade Ministry Publishes Full Commodity List – 21 Tariff Posts Confirmed for DSDI Management

JAKARTA – May 27, 2026 – One day after the Ministry of Trade published the full list of 21 tariff posts subject to the new centralized export system, Finance Minister Purbaya Yudhi Sadewa announced that 10 major palm oil exporters are being formally investigated for suspected under-invoicing and transfer-pricing practices. The investigation has named Singapore-based Wilmar International Limited and Musim Mas Group as among the companies under scrutiny.

This 48-hour update covers the Finance Minister’s May 26 announcement, the confirmed 50% gap between reported and actual prices, the Coordinating Minister’s clarification that no country will be excluded from the policy, the collapse of fresh fruit bunch prices affecting smallholder farmers, and the revised implementation timeline moving full mandatory control to January 1, 2027.

The Essentials: Who, What, When, Where, Why, How (Last 48 Hours)

Who: Indonesia’s Finance Minister Purbaya Yudhi Sadewa; Coordinating Minister for Economic Affairs Airlangga Hartarto; Deputy Minister of Agriculture Sudaryono; Wilmar International Limited (Singapore-based); Musim Mas Group (Singapore-based); 10 major palm oil exporters under investigation; PT Danantara Sumber Daya Indonesia (DSDI); Indonesian Oil Palm Farmers’ Association (APKASINDO); and smallholder farmers across Indonesia.

What: Five major developments since May 26:

  • Finance Minister announced formal investigation of 10 major palm oil exporters for under-invoicing, naming Wilmar and Musim Mas
  • Under-invoicing gap confirmed at approximately 50% – export data reported to Singapore is roughly half of actual values
  • Coordinating Minister Airlangga confirmed “no country will be excluded” from the new export policy
  • Fresh fruit bunch (FFB) prices have collapsed to 1,500-2,500 rupiah per kilogram (down from 3,800 rupiah)
  • Full implementation timeline clarified: Phase 2 mandatory control begins January 1, 2027 (not September 1, 2026)

When:

  • May 26, 2026 – Finance Minister announces investigation of 10 exporters
  • May 26, 2026 – Coordinating Minister Airlangga states “no country excluded”
  • May 26, 2026 – Deputy Minister Sudaryono meets industry stakeholders
  • May 26, 2026 – Trade Minister Regulation Number 25 of 2026 published (previously reported)
  • June 1, 2026 – Phase 1 transition period begins
  • January 1, 2027 – Full mandatory implementation begins

Where: The investigation covers palm oil exports from Indonesia to international markets, with specific focus on trading companies in Singapore. The policy applies to all Indonesian palm oil exports regardless of destination.

Why (Immediate Cause): The investigation follows the government’s discovery that export data reported to Singapore was approximately 50% below actual values. Finance Minister Purbaya stated: “The records here are correct, but the ones there are not. So their reported export data is lower than it should be, roughly 50% below the actual figure.”

How (Mechanism): The government’s monitoring system flagged 10 exporters for alleged under-invoicing. Companies shipped or sold CPO to trading firms in Singapore, which then resold cargo to the United States after price markups of as much as 50%. DSI will operate in two phases, with full transformation into a trading company starting January 2027.

Specific Updates in the Last 48 Hours (May 26–27, 2026)

1. Finance Minister Announces Investigation of 10 Major Exporters (May 26)

On May 26, 2026, Indonesia’s Finance Minister Purbaya Yudhi Sadewa announced that 10 major palm oil exporters are being formally investigated for suspected under-invoicing and transfer-pricing practices.

Companies Named in the Investigation:

CompanyHeadquartersDetails
Wilmar International LimitedSingaporeOne of the world’s largest oil palm plantation owners with 234,334 hectares in Indonesia
Musim Mas GroupSingaporeMajor integrated palm oil company operating in 14 countries
8 other exportersVariousNames not publicly disclosed as of May 27, 2026

Finance Minister’s Statement: Purbaya stated that the authorities’ monitoring system flagged these exporters for alleged under-invoicing. He explained that domestic export documents in Indonesia appeared accurate, but inconsistencies emerged in transit records and destination pricing.

Neither Wilmar International nor Musim Mas Group immediately responded to requests for comment as of May 27, 2026.

2. Under-Invoicing Gap Confirmed at Approximately 50%

The Finance Minister’s announcement provides the first official confirmation of the magnitude of the under-invoicing scheme.

Confirmed Gap: According to Purbaya, companies shipped or sold CPO to trading firms in Singapore, which then resold cargo to the United States after price markups of as much as 50%. The reported export data is approximately 50% below actual figures.

Connection to Previous Reporting: The May 23 article reported that investigators had found prices reported to Singapore at half their true value. The Finance Minister’s May 26 statement officially confirms this finding.

Quote from Finance Minister Purbaya: “The records here are correct, but the ones there are not. So their reported export data is lower than it should be, roughly 50% below the actual figure.”

3. Coordinating Minister Clarifies “No Country Excluded” from Policy (May 26)

On May 26, 2026, Coordinating Minister for Economic Affairs Airlangga Hartarto stated that no country will be excluded from Indonesia’s new natural resource export policy.

Key Clarification: Despite existing bilateral cooperation with certain countries, exports of CPO, coal, and ferroalloy will have to be documented through DSI (DSDI). This differs from Indonesia’s foreign exchange proceeds policy, which exempts several partner countries with existing bilateral agreements (including the United States).

Connection to Previous Reporting: The May 26 article noted that Singapore’s official response to the under-invoicing allegations had not yet been reported. While Singapore has not formally responded, this statement clarifies that Singapore will not be exempt from the policy’s requirements.

4. Fresh Fruit Bunch (FFB) Prices Collapse; Farmers Affected

The policy announcement has had immediate real-world consequences for smallholder farmers across Indonesia.

Price Impact:

PeriodFFB Price (per kg)Change
Before policy announcementApproximately 3,800 rupiah
After policy announcement1,500-2,500 rupiahDown 50-60%

Farmer Impact: According to Mansuetus Darto, chairman of the Indonesian Oil Palm Farmers’ Association (APKASINDO): “Fruit is being left to rot in the fields as the collectors have stopped picking up fruit with trucks, and farmers don’t have their own trucks.”

Refiner Response: Several palm oil refiners have stopped purchasing fresh fruit bunches from smallholders while waiting for clarity on the new export framework.

5. Government Responds to Farmer Concerns (May 26)

The government took action on May 26, 2026, to address the impact on smallholder farmers.

Deputy Minister’s Meeting: Deputy Minister of Agriculture Sudaryono met with industry stakeholders on May 26, 2026, and confirmed that producers agreed to buy fresh fruit bunches at reference prices set by local governments.

Ministry of Agriculture Clarification: The Ministry of Agriculture clarified that PT DSI will serve as manager and supervisor of the one-gate export mechanism, operating transparently, accountably, and without charging fees or seeking profits from export transactions.

6. Full Implementation Timeline Revised: January 1, 2027

Multiple government officials have now provided a more detailed timeline that clarifies the dates reported in the May 26 article.

Revised Implementation Timeline:

PeriodEventDetails
June 1 – August 31, 2026Transition evaluation periodExisting exporters handle transactions; reporting submitted to DSI
September – December 31, 2026Mixed transition period (voluntary)Exporters that are ready may fully transfer activities to DSI
January 1, 2027Full mandatory implementationAll exports of three commodities must be conducted through DSI

Important Clarification: The Trade Minister clarified on May 25 that September 1 marks the start of a voluntary “mixed transition period” where exporters who are ready may transfer activities. Full mandatory implementation does not begin until January 1, 2027.

Comparison to May 26 Article: The May 26 article stated that Phase 2 full implementation would begin September 1, 2026. The clarified timeline shows that September 1 begins a voluntary mixed transition period, with full mandatory control starting January 1, 2027.

7. DSI’s Role in Phase 2 Clarified

Coordinating Minister Airlangga provided additional clarity on DSI’s role in Phase 2.

Phase 1 (June 1 – December 31, 2026): DSI functions as an appraiser and intermediary between sellers and buyers.

Phase 2 (Starting January 2027): DSI transforms into a trading company that directly purchases commodities from exporters, holds the goods, assumes trade risks, and sells them on the international market. Revenue from sales will be received in the destination country’s foreign currency and then fully repatriated to Indonesia.

8. Analyst Assessment: Limited Near-Term Impact

Financial analysts have assessed the policy’s impact on the palm oil market.

Key Assessment: Limited near-term impact is expected as no fees have been introduced yet. However, there is potential for additional fees in the second phase, though details remain lacking.

Price Spread Impact: If implemented, higher export costs could widen the Indonesia CPO discount versus the Malaysian benchmark.

Earnings Sensitivity: Analysts estimate that every Rp100,000 per ton increase in export-related fees could reduce FY27-28F earnings by 1-4%.

9. Singapore’s Response Still Not Reported

As of May 27, 2026, Singapore’s official response to the under-invoicing allegations and the new export policy remains unreported.

Current Status: Singapore-based companies Wilmar and Musim Mas have been named in the investigation, but neither the companies nor the Singaporean government have issued formal statements.

What to Watch: Any statement from Singapore’s Ministry of Trade and Industry or other relevant authorities would be a significant development, potentially affecting diplomatic and trade relations between the two countries.

Why This Matters (Updated for May 27)

The investigation announcement, the confirmation of the 50% under-invoicing gap, and the collapse of fresh fruit bunch prices are significant developments that change the landscape described in the May 26 article.

For the companies under investigation: Wilmar International Limited and Musim Mas Group – two of the world’s largest palm oil companies – are now formally under investigation. The outcome could include penalties, fines, or other enforcement actions. Neither company has responded to requests for comment as of May 27, 2026.

For Indonesian palm oil exporters: All 10 exporters under investigation face potential legal and financial consequences. Exporters not named in the investigation should still prepare for DSDI oversight, with full mandatory control beginning January 1, 2027.

For smallholder farmers: The collapse of fresh fruit bunch prices to 1,500-2,500 rupiah per kilogram (down from 3,800 rupiah) is causing immediate hardship. Farmers are leaving fruit to rot in the fields because collectors have stopped purchasing. The government’s agreement on reference prices may provide relief, but implementation details remain unclear.

For global buyers of palm oil products: The investigation confirms the government’s determination to enforce the new system. Buyers of oleochemicals, biodiesel feedstocks, PFAD, and other derivatives should prepare for DSDI oversight starting in Phase 2.

For Singapore: The naming of two Singapore-based companies in the investigation, combined with the Coordinating Minister’s statement that no country will be excluded, puts diplomatic focus on Singapore. The government has not yet issued an official response.

For investors: The analyst assessment that limited near-term impact is expected (as no fees have been introduced yet) provides some reassurance. However, potential fees in Phase 2 could widen the Indonesia CPO discount and reduce earnings by 1-4% per Rp100,000 per ton increase.
