The page this article got its info from (https://www.ithome.com/0/889/173.htm) says (according to Safari’s translation):

“IT Home News on October 13, @Olrak29_ found that the AMD processor code-named "Sound Wave" has appeared in the customs data list, confirming the company's processor development plan beyond the x86 architecture”

I think that means they are planning to export parts.

I think there still is some speculation involved as to what those parts are, and they might export them only for their own use, but is that likely?

I think the chips are being imported from Taiwan to the US. At this point they are prototypes being tested. AMD wouldn't make a chip this complex for their own use; these were likely ordered by Microsoft or Valve.

Valve seems like a reasonable guess honestly.
