You are correct! And the problem remains. What is a "product" to one is a
"component" to another.
So when you buy a display card for your computer and it has a UL mark on it,
how do you know it is for the board material only?
When I buy a power cord and it has a UL label on one end, can I assume that
the connector is included? (which, by the way, is a terribly unsafe device
and acceptable to UL!).
As I see it, the problem is the same and at the moment unresolved.

I think it is...
The UL mark only certifies that the materials used in the bare board, and
doesn't tell you anything about the assembly (I think... am I crazy?)
The RoHS (or now incorporated into CE) mark represents the entire product

I agree, but I would also caution you to think about something.
When you mark something on a bare board as being "lead free",
are you telling the world that only the bare board is lead free?
...or are you implying that the final assembly is lead free?
Be cautious about marking a bare board, and then losing control of it later
on.
Maybe the assembler should be marking the final assembly as "compliant"?
Does anyone else have experience with this?
I'm nervous about stamping a bare board, and then someone later down the
line decides to assemble the board with different criteria...
