I have a dolly that says "Proud to be assembled in the US". That does not say where the metal came from, where the tires came from or who manufactured them, or who manufactured the pieces. The welding may have been done in the US, may not, and probably was done by robot anyway. When I see that I always wonder if they put the axle and wheels on in the US and called that assembly. They don't mention parts at all.Had that been a piece of machinery, it would have had to be stated that they used foreign parts or assembled elsewhere.
