Makes sense then, that I saw them at a place called "...Medical Supply & Pharmacy"

Not all hemostats are medical devices, just like not all tweezers are for medical use. Specialty tool shops and some hobby shops carry them. Seems they are not a medical device if they are not sold as such and come with a disclaimer "not for medical use"

You can get them online too, medical grade or not.

"They are also considered drug paraphernalia if present with illegal drugs."

So is any other tool if it's used to facilitate drug use.
