"External input fuse required:" (near top, p.2).
You could add surge protection, more filtering, etc. But probably not a big deal.
Obviously, having uninsulated parts, it needs an enclosure, but otherwise it meets UL/IEC 60950 (a safety standard), and all the other things needed to sell something.
BTW, EMC approvals are helpful, but not sufficient for selling a final product -- you still have to test, in case you've added things, or managed to make existing clean parts dirty somehow.
