Question about Shipping order

So my question is I’m going to have my supplier in China put the labels on the packages and prep everything, Amazon doesn’t have to do anything. When shipping the order on the Send to Amazon page it says Information/Action: Prep not required, No labeling required… Is that correct or does it need to say Prep by Seller, Labeling by Seller?? Idk, maybe they changed it around, or is that what it should say if my manufacturer is going to do all that?? Thanks in advance guys!!
