As others have mentioned, the rules for shipping wine do not apply to wine declared at entry. I have shipped a lot of wine back with no problem, assuming that I have declared it at time of entry.

A bigger problem may be state regulations. Many states, including Washington State where I live, have their own import regulations, and these will have to be met if you are a state resident and you are over the free limit before you can clear US customs in that state.
