Porsche can't sell most of its cars in the U.S. because of chip source

I briefly worked for an auto supplier. Everything that went into the components we produced needed a bill of materials for customs. Records were methodical and detailed, including origin, material composition, and a bunch of other things.

If itwas not accurate, fines were extremely large (relative to the component value)

I don’t know anything about this situation or how these imports work, but I know from adjacent work that companies usually self monitor for violations of sanctions because the consequences of sanctions evasion can be extraordinary. It’s often less about having been caught but demonstrating proactive measures. I would further not be surprised in the least if they did have to supply a BOM with country of origin for every car imported not just for sanctions but also tariffs.

It is international division of labor. Silly thing, exUSSR become late into semiconductor market, so all sub-micron deals was under Asian manufacturers, but nobody want to work with older tech.

Rumors said, in 2000s, Russians made near all chips for quartz watches (yes, even for Japan).

I think, it is really possible, Covid so hard hit market, that some automotive deals moved to Russians also. They have not too much, but low power 100nm (bought from AMD Dresden) is worth something.

And yes, Russians have licensed internal manufacture of some Atmel AVR chips.

Just like the US has no issues using Russian oil or uranium.
