UL does not ask to indicate the recognized mark-RU, only for the UL listed products, the "UL" with a circle symbol is necessary, but for "RU", it's not an necessary element.3 t! w! L7 {" C. Q

Not sure what's your question finally is. Did you want to confirm whether the PCB which your factory use complies with UL's requirements? and as to the marking requirements, I believe it's already clear:
