Many US vendors get it right, but just as many don't seem to care, or even know that things are different outside of CONUS. Adapters supplied with "new" products are AFIK not permitted, though it often happens. The problem there, is the quality and safety of such adapters is often poor. (Often low cost brittle plastic things from the Far East.) In this case, as the PSU is intended to be used with a device that has exposed metallic parts connected to one side of the DC lead, I suspect (I admit that I do not know for sure) that the AC input to that PSU should include a safety ground, connected to (among other things) the transformer inter-winding shield. It's been a very long time since we've seen any similar PSU's for laptops and similar devices, that do not have a three pole power inlet, that includes a safety ground. Even, if the DC output is fully isolated from anything on the AC input side. Take care.
