Trade-based money laundering (TBML) is the most common method sanctioned entities use to move value across borders without triggering financial controls. FATF identifies it as one of the three main money laundering methods.
TL;DR: TBML moves value through international trade transactions by manipulating invoice prices, shipping phantom goods, or using front importers. Sanctioned entities use TBML to access the financial system indirectly, because trade finance is less scrutinized than direct wire transfers.
| Method | How it works | Red flag |
|---|---|---|
| Over-invoicing | Importer overpays exporter; difference = value transfer | Price far above market rate for the commodity |
| Under-invoicing | Exporter undercharges importer; difference = value transfer on import side | Price far below market rate |
| Phantom shipments | Invoice for goods that never ship; pure paper transaction | No shipping documents, no customs records |
| Multiple invoicing | Same shipment invoiced multiple times to justify multiple payments | Duplicate invoices for one bill of lading |
OFAC's sanctions on Iran, North Korea, and Russia have repeatedly targeted TBML networks. The 2020 designation of a network of front companies based in the UAE, Hong Kong, and Singapore that facilitated Iranian TBML showed how these networks operate across multiple jurisdictions.
TBML detection requires comparing transaction prices against market benchmarks. For AI agent payments, the risk is lower (agents typically do not process trade invoices), but any agent handling B2B payments should validate that payment amounts correspond to verifiable goods or services.
