There are probably others.

My (Thai) wife needs medicine shipped from Thailand since we just returned to the US after a long time in Thailand and it will take us six months to get an appointment with a neurologist and we "only" brought three months of meds (max allowed by US law). Apparently, that option (even having family send it first class / boat mail) is out now. We may have to literally fly to Thailand (or Mexico, or something) to get her damn medicine.

Tried to order some Zyn mini 1.5mg pouches from the EU today, my supplier isn't shipping currently as the tariff would be as much or more than the order.

One is a serious problem, one is a nootropic "want" that helps me focus at work when I need a little extra push. Will probably replace that with nicotine gum since it's available in the US domestically.

Curious if / how this will impact anyone else?

TL;DR if you are dependent upon things being mailed to you from abroad, you might want to look into it. If you don't live in the US and your business depends on mailing things to US customers, RIP your business I guess. Sorry.
