That is not what the link says. It says that goods consignments are not accepted -- which is not at all the same thing as "does not ship to the US anymore". The link explicitly says that they're continuing to ship letters, will continue to ship goods via another service, and (I can only presume) will continue to accept personal packages, since those aren't affected at all by these tariff changes.
The discussion on this topic on HN is far more heat than light.
If I buy a Swiss watch (<$800) I’ll have to use DHL or UPS (though AFAIK, they also use national post in places) so I’m SOL.
But if my Swiss friend mails me a watch they can use Swiss Post still? Unclear.
I don't know if the Swiss post office has realized this, but it's true.
Edit: one bit of nuance (see my comment downthread with some of the actual laws and the EO) is that if you buy a watch from Chrono24 or something then it's more like the Temu use-case, and I think the personal exemption probably doesn't apply? But if you go to Switzerland and pick up a $799 watch and post it back or carry it on a plane, then there's no problem.
I have to actually deal with the former.
