What happened
FinCEN’s foundational guidance on trade-based money laundering identifies double invoicing—billing the same goods or services more than once—as one of the basic schemes used to move illicit value through legitimate-looking trade channels. The advisory sits alongside related manipulations such as over- and under-invoicing, all of which exploit the paperwork underpinning international trade rather than the physical movement of goods itself.
The guidance sets out a series of associated red flags. These include a customer’s inability to produce appropriate documentation, such as invoices, to support a requested transaction; significant discrepancies between how goods are described across the bill of lading, invoice, and certificate of origin, which can arise even when no goods move at all; third-party payments made by an intermediary apparently unrelated to either the buyer or seller; and amended letters of credit for which no reasonable justification is given.
Why it matters
These indicators matter because they point to the structural weakness at the heart of trade-based money laundering detection: financial institutions typically see only the documents associated with a transaction, not the underlying goods. Invoices, bills of lading, and certificates of origin can be fabricated by the launderers themselves, with no neutral third party verifying their accuracy. Double invoicing in particular is difficult to detect through a single institution’s records, since it depends on identifying that the same shipment has been billed more than once—something that may only become visible when documentation is compared across counterparties or jurisdictions.
For compliance teams, this reinforces the need to treat trade documentation with appropriate scepticism rather than as self-evidently reliable. Discrepancies in goods descriptions, unexplained letter of credit amendments, and unusual third-party payment structures each warrant closer inquiry, particularly when they occur in combination.
Context
The indicators described in FinCEN’s advisory remain a reference point for identifying trade-based money laundering typologies, including phantom shipments where documentation exists but no goods are actually transported. Because these schemes are built on paper trails rather than physical evidence, effective detection depends on institutions’ ability to scrutinise documentary inconsistencies and unusual payment arrangements, rather than relying solely on the apparent legitimacy of the trade instruments presented to them.
