Not legal in the USA, unless they have an FCC ID. They cannot be used.
They are VHF radios which could be used for MURS…but they aren’t type accepted, so illegal there. If they had the Part 15 approval, which they don’t, then they could be used for 2 meter amateur use.
They have no type acceptance for any service in the USA.
Perhaps an expensive paperweight or doorstop… that is it.
Requests for approval are submitted by the manufacturer. All radios must comply with governement standards and are done by a whole model series, not individually.
Radios can be seized by customs with no refund to you.
