I am building a set of shelves using oak plywood.
My question is, what grit does the manufacturer use?
Can I start with 150, or do I start at 100?
I know I will finish at 220.

I usually start with 150 on hardwood plywood. Very occasionally, with
a crappy or mishandled material, I'll use 120.
When I'm staining it, I stop at 150, as well. <G>
For straight-up clears, it's 150 -> sanding sealer -> 220 -> finish
It's already been done at 150, I'm sure. If you haven't hacked it, wipe
with a damp rag, let dry, sand by hand (backed) with 220. More than 150 on
peeled oak is slight overkill, but you don't want to be too aggressive and
end up with the latewood proud of the early.
If it's anything like the oak plywood around here, do not let the 100
grit get anywhere near it. The face veneer is thinner than paper and
you can sand through it in seconds with 100 grit. Even the 150 is
chancy. You may be able to start with the 220, if necessary use 150 very
lightly, or 180 first.
Better to be stuck up in a tree than tied to one.
