How hard would it be for Iran to open a shell company in third-party country like, say, Iraq to mask the transaction?
Even more fun when the US gets another country to do the arresting dirty work.

But iran.. I don't know what their customs rules are but if you pay import fees, probably unlimited amounts.
How much you can buy? A lot.. eg. 10k voltage regulators is such a common order size, that they have a predefined lowered price even in online stores (without having to contact sales):

This is some kind of fantasy? I can go to a million websites or into a store with cash and I can buy microchips for $0.08 without signing any contract. What's next, you are going to keep track of nuts and bolts?
