Samin Tan has been formally accused of laundering Rp18.1 trillion, or about $1.1 billion, from coal sales tied to a terminated mining concession, a case that underscores how illicit commodity flows can distort tax receipts, state non-tax revenue and governance in Indonesia’s coal sector.
Indonesia prosecutors accuse Samin Tan of Rp18.1 trillion laundering
Prosecutors said in a Jakarta court that the money came from exports of 5.88 million metric tons of coal from PT Asmin Koalindo Tuhup’s area and was not paid into the official account of the concession holder. Instead, they allege the proceeds were diverted through a rotating set of company accounts, then fragmented across affiliated firms and overseas entities before being used for the businessman’s benefit.

The scale matters well beyond the criminal case. If proven, the allegations point to a large-scale attempt to conceal the true beneficiary of export revenues, depriving the state not only of income tax but also of Indonesia’s mineral and coal-related non-tax revenue, or PNBP. That hits a sensitive point for a country still dependent on coal for power generation and export earnings, even as policymakers try to tighten oversight of the resource sector.
For investors, the case is a reminder that legal and governance risk can sit alongside commodity risk in Indonesian coal names and their financing structures. A probe of this size can raise questions about counterparty risk, asset ownership and the durability of cash flows, especially where export proceeds move through affiliated vehicles rather than operating accounts. It also reinforces the premium investors demand for transparency in jurisdictions where ownership chains, export contracts and asset transfers can be difficult to verify.
The indictment alleges the proceeds were moved through accounts linked to PT Beyond Property, PT Bagas Bumi Persada and other affiliated firms, with part of the money routed through PT Black Diamond before being withdrawn and handed over in cash. Prosecutors also said some funds were used to buy 104 land parcels in Tangerang and a portfolio of offices and apartments, illustrating how commodity revenue can be converted into hard assets to obscure its origin.
The case now moves into the court process, where the key questions will be whether prosecutors can prove the flow of funds, the control structure behind the accounts and the link between the coal sales and the assets acquired. For the market, the wider significance is less about one businessman than about the vulnerability of commodity supply chains to opaque intermediaries, especially in a sector as strategically important as coal.
