The point you are missing is that it is illegal for a RO to engage in any type of business activity beyond serving as liaison office for its parent company in China. You can’t do any packaging under the RO. You can’t buy any items for production nor can ship out manufactured products under the RO.
Considering the current crackdown and harder restrictions on ROs in China, I would avoid going beyond the legal scope of activities you are authorized to. It used to be OK for service providers, but for products it would be a big no-no.
