The phantom shipment is the limiting case of misinvoicing: rather than misstating the value of real cargo, the parties dispense with the cargo. Invoices, packing lists and bills of lading are produced, a bank settles against them, and the payment is the entire purpose.
It is caught by physical corroboration — port records, carrier confirmations, container tracking, vessel position histories — because the documents themselves will be internally consistent. The FATF and Egmont studies treat the inability of an applicant to evidence movement of the goods as a standalone indicator.
