#7.1 Mechanics of Trade-Based Money Laundering

Trade-Based Money Laundering (TBML) involves the exploitation of international commercial trade transactions to move illicit capital, transfer value across borders, or evade taxes under the legitimate cover of physical commodity shipments.

Primary TBML Modalities

• Over-Invoicing: Declaring commodity prices significantly higher than true market value to transfer capital out of the importing jurisdiction.
• Under-Invoicing: Declaring goods far below fair market value, allowing the foreign importer to sell goods at market prices and retain the difference abroad.
• Ghost Shipments: Fabricating complete sets of commercial documentation (bills of lading, invoices, customs certificates) for shipments that are completely empty or physically never occurred.
• Multiple Invoicing: Submitting the exact same commercial invoice to multiple trade finance banks to obtain duplicative credit facilities.

#7.2 Unit-Price Discrepancy Benchmarking

Automated TBML inspection engines utilize multi-modal document intelligence (OCR) combined with international trade pricing APIs:

1. Parse commercial invoices and customs declarations to extract declared Harmonized System (HS) tariff classification codes, unit volume, and invoice total.
2. Query international commodity benchmark indices (e.g. London Metal Exchange, ICIS, Platts) for the exact transaction date window.
3. Compute price variance ratios:

1. Deviations exceeding +/- 30% without verifiable technical justification (e.g. custom patented alloy specifications) trigger mandatory compliance holds.

#7.3 Proliferation Financing & Dual-Use Export Screening

Under UN Resolution 1540 and international export control regimes, institutions must screen trade finance transactions to prevent the illicit procurement of weapons of mass destruction (WMD) dual-use components:

• Screen all cargo descriptions against military and dual-use embargo lists (e.g. high-precision CNC machine tools, specialized centrifuges, maraging steel).
• Correlate shipping lines with satellite Automated Identification System (AIS) vessel telemetry, flagging deceptive shipping practices such as AIS dark voyages, flag-of-convenience switching, or unauthorized mid-ocean ship-to-ship (STS) cargo transfers.
