Most export-controlled technology is dual-use: it has a real civil market and a military application. Bearings, machine tools, thermal imaging modules, navigation components, microcontrollers, radio-frequency amplifiers and oscilloscopes all have unremarkable commercial customers, and all appear in weapons recovered from conflict zones.
Diversion is the practice of buying such items on the open market through parties who attract no attention, and moving them onward to an end user who could not have bought them.
How it works
The purchasing entity is chosen for its ordinariness. It is a genuine distributor, or a genuine electronics importer, or a genuine maintenance company, in a country with no restrictions. Its orders are not anomalous because it places orders like them all the time.
The order itself is unremarkable. The quantities are commercial. The items are catalogue parts. The payment is by ordinary transfer from a real bank account.
What is false is the destination, and that is not on any document the seller sees.
Where the seller’s checks stop
An exporter screens its customer against sanctions lists and checks whether the item and destination require a licence. Both checks pass. The customer is not listed and the destination is not restricted. The item ships lawfully.
The canonical list is not in the BIS case compendium, as this page previously implied, but in the Export Administration Regulations themselves — Supplement No. 3 to Part 732, the “Red Flags”. It is built around what a customer does even when the formal checks clear: reluctance to offer information about the end use1 , product capabilities that do not fit the buyer’s line of business2 , routine installation, training or maintenance services declined3 , a freight forwarding firm listed as the product’s final destination4 , willingness to pay cash for a very expensive item when the terms of sale call for financing5 , packaging inconsistent with the stated method of shipment6 , and a shipping route abnormal for the product and destination7 .
The supplement is also explicit about what to do with them. Do not self-blind: do not cut off the flow of information that comes to the firm in the normal course of business7 . If there are red flags, inquire8 . And if they cannot be explained or justified and you proceed, you run a risk9 .
These are behavioural indicators, not documentary ones, and that is the point: at the moment of sale the documents are clean and the behaviour is not.
The component trail
Diverted components are unusual among the subjects on this site in that they can be recovered and examined. Field investigation organisations working in conflict zones document manufacturer markings, part numbers, date codes and batch identifiers on recovered materiel, and trace them back through distributors to the last documented lawful sale.
That work produces something no financial record can: a physical object at the end of the chain, with an identifier that ties it to a specific shipment. The gap between where the distributor’s records say the part went and where it was found is the diversion, evidenced.
How it is caught
Three routes dominate the public record.
The first is the component trail described above, working backwards from recovered materiel.
The second is trade data, working forwards: monitoring third-country imports of high-priority commodity codes against those countries’ own industrial capacity, and against their exports to the restricted destination.
The third is the behavioural indicator at the point of sale, which is the only one that operates before the goods have gone. Enforcement narratives in this area frequently rest on internal correspondence in which the exporter’s own staff raised exactly the question the regulation says to raise8 and it was closed without an answer. That is how a diversion becomes a wilful blindness case rather than a misfortune, and it is why the “do not self-blind” instruction7 is in the text at all.
