A nickel grade written on a test document cost the state Rp401 billion, and the case shows where mineral value is actually decided

The Attorney General's Office set out the details of a nickel export case at a press conference in Jakarta on 31 August 2026. PT Ceria Nugraha Indotama, a holder of a production operation mining permit in Southeast Sulawesi, returned Rp401,653,737,469.69 to the state. The figure is the loss calculated by BPKP, the Financial and Development Supervisory Agency, and the money has been deposited into a government account at Bank Mandiri.

The mechanism at the centre of the case is worth understanding precisely, because it is not a story about ore being stolen. Nothing was taken that was not mined and shipped in the open. What was altered was a number on a piece of paper.

What the case turns on

Saiful Bahri Siregar, Director of Investigation at the Special Crimes division of the Attorney General's Office, described the scheme as the arrangement of nickel grade test results so that assays came back below 1.7 percent. He stated that the company, acting together with state officials, obtained test results at that level, and that PT CNI used documents that were not valid to conduct nickel exports unlawfully, causing loss to state finances.

The 1.7 percent line is the threshold Indonesian rules use to divide nickel ore that may leave the country from ore reserved for domestic processing. Prosecutors allege the documents placed CNI's ore on the exportable side of that line when the material did not belong there.

There was a second gap. Across 2017 to 2019 the company held a production operation permit but had not obtained an approved RKAB, the annual work and budget plan every Indonesian mining permit holder must have in force. It nonetheless secured export recommendations. The investigation covers the period 2017 to 2020.

The investigative record is substantial: 116 witnesses examined, three expert consultants engaged, 143 documents seized, and searches conducted at three locations. Prosecutors have said the case continues and that the return of the money does not close it, with work ongoing to establish individual criminal liability.

Grade is the price

Sirkularium reads this as a valuation case, and the clearest one to appear in Indonesian resource governance this year.

Nickel laterite ore is not a uniform commodity. Its value is set almost entirely by assay: nickel content first, then iron, cobalt, chromium, silica, magnesia, and moisture. The benchmark price formula Indonesia revised in 2026 reflects exactly this, moving beyond nickel content alone to account for accompanying minerals, and shifting the unit of account from dry metric tonne to wet metric tonne to capture moisture. Royalty is a percentage applied to a reference price that is itself indexed to grade. Export eligibility is a function of grade. Smelter feed specification is a function of grade.

Every number that matters in the nickel trade, the price, the royalty, the export permission, and the downstreaming obligation, is downstream of a single laboratory figure. That makes the assay the most valuable document in the chain and the most worthwhile to falsify.

Seen that way, the Rp401.65 billion is not an unusual sum extracted through an exotic scheme. It is the arithmetic consequence of moving a decimal in the right direction across three years of shipments.

Where this sits in a wider programme

What makes the timing notable is how much of Indonesia's 2026 policy agenda is aimed at precisely this failure mode, from several directions at once.

The benchmark price formulas for nickel and bauxite were rebuilt to make the priced characteristics of ore harder to misrepresent. Production quotas were tightened and allocated with reference to royalty contribution, which raises the value of an accurate production record. PT Danantara Sumberdaya Indonesia now runs export oversight across coal, crude palm oil, and ferroalloy, joining SIMBARA, the national single window, and customs data, with transaction quantity and quality among the things it checks, and with under invoicing and transfer pricing named as its targets. A national mineral and strategic commodities exchange is due to begin operating on 1 January 2027 to establish an Indonesia Reference Price.

Each of those instruments assumes the underlying physical measurement is sound. A reference price built on declared grades is only as good as the assays behind it. This case is a useful reminder that price discovery infrastructure and physical verification infrastructure have to advance together.

The enforcement side has also become materially more capable. BPKP produced a loss figure to the rupiah, and the full amount was recovered and deposited rather than merely ordered. That is a working chain from audit calculation to restitution, and it is the same chain that gives environmental economic loss figures their force when courts apply Permen LH No. 7 Tahun 2014.

Sirkularium's view

The outcome here reflects well on the institutions involved. A specific loss was calculated by an audit body, the full sum was returned, and the criminal process continues rather than treating repayment as a settlement. For government and public institutions, three observations follow.

First, assay integrity deserves the same institutional attention that price formation is now receiving. Grade determination sits with commercial laboratories and surveyor firms, and the quality of that work decides the value of every subsequent number. Accreditation requirements, independent check assays on a sampling basis at the point of loading, and retention of sealed reference samples would make the kind of arrangement alleged here far harder to sustain. Tying assay results into SIMBARA at the point of testing rather than at the point of declaration would close the gap further.

Second, the RKAB finding points to a coordination issue worth fixing by system rather than by case. A permit holder without a current approved work plan should not be able to obtain an export recommendation. That is a data integration problem, and Indonesia is already building the integration layer that would catch it.

Third, and this is the observation Sirkularium would most want carried forward, the same logic applies to the environmental ledger. An assay that understates grade understates value, royalty, and obligation in one move. A land cover figure or a reclamation extent that goes unverified does exactly the same thing on the environmental side, and with far less scrutiny, because no equivalent of BPKP routinely recalculates it. GIS and remote sensing make independent verification of concession condition straightforward and repeatable. Applying it as standing practice would give the environmental column the same evidentiary weight the financial column now demonstrably has.

For operators, the practical reading is that documentation is now the exposure. Grade, tonnage, permit status, and export eligibility are increasingly cross checked across state systems and reconstructable years after the fact. The same is becoming true of environmental position, where the Ministry of Environment and Forestry expects measured figures. A company holding an independently verified valuation series covering its land, water, and ecosystem position is arguing from evidence, and evidence is what this case shows the state is now equipped to test.

What to watch next is whether individual liability is established, whether assay and surveyor oversight is tightened in the critical minerals Presidential Regulation now being prepared, and whether grade data begins flowing into national systems at the point of testing.
