Drain cleaner is NaOH (lye).

Sulfuric is sold as battery acid for refilling lead acid batteries.

Muriatic is HCl sold as concrete cleaner.

Nitric is hard to buy, but there are some guides on making it.

Label is very faded but just one example:

I've never seen it in a big box store, but small mom and pops type hardware stores here in California have had it around. It seems to be part of a small distribution network and comes from Mexico.

Nuts. Never seen H2SO4 used for drains. They don't call it "oil of vitriol" for nothing. You can actually test a distillation of pure sulfuric because a drop will burn through a paper towel in seconds.
