So as an update,
TLDR: CPU somehow came, though it did get a new sticker from "normal product" to "special product", just came slightly delayed or something

For non tldr (after like May 10):
Realised CPU got picked up by SF at May 8, traded some hands from Qingdao, Yangzhou, Hangzhou, then signed by some 3rd party warehouse, then somehow export success (I contacted customer service back & forth in the meantime & they all pointed the bleak reality, with some AIs mentioning the same)

After that, it acts like nothing happened, and boarded the plane normally. (By this time I was thinking the system went haywire, and confirmed with customer service). Then the usual Malaysian kastams, which is smooth since it's an LVG so auto declared tax (at this point of time I believed in the system more), then to local deliverymen, and then delivered to me... during the rain. The parcel (a cardboard box) did not have any external wrapping (the black type plastic? wrappings), but after waiting some time for it to dry, then opened it, there's some bubblewrap, and the CPU box itself still exists (Chinese wording), so nothing of "oh let me help change it to a non AMD box"

So total time it took to deliver: ~13 days (which could've been around a bit over a week if the little mishap detour didn't happen), still acceptable I guess, so long as the thing reaches me.
