My garage is unpainted dry-wall. I guess I can tell what type it is if I look at it (or I can look at teh backside of an unfished closet and see what it says). What should I look for “Made in China” or will it not be that obvious?
If your house doesn’t smell like rotten eggs, ie. sulphur, then you’re probably okay.
There is no “made in” mark on finished drywall, so you can’t tell the origin by looking at it. And most of the time the drywall installer orders from a supplier who delivers it to the jobsite, so the guy who hung the drywall probably wouldn’t know either. If your house was built between 2002 and 2007 and smells like rotten eggs, you might want to investigate further.
