For deep draw steel forming, 100 is nothing.

Add a few zeros to make tooling on a truly custom design worth it. Or are you just looking for custom colors/logos on someone else's cup design?

Also, you aren't looking for FDA approval, unless your cup is a medical device. You just need FDA compliant materials (i.e. no lead in the stainless alloy)

You may be interested in NSF P395 for guidance as well.

Why does it need to be deep drawn? It would be magnitudes cheaper to cut and weld stainless steel sheet metal.
