Probably yes, but some of the countries we've outsourced to have improved their quality of living. So it is possible that made in America could be cheaper than making it overseas and then shipping it over (I think this is unlikely, but it is at least hypothetically possible).

Alternatively, touched on in the article, it could be seen as preferable to get some supply chains entirely inside the US -- would have been nice to have more US mask manufacturing a couple years ago.

They didn't mention any changes to law or trade policy in the article so I guess these companies are looking in the US for economic reasons. They might just see the shortened supply line as worth the US manufacturing costs...
