Not going to say it won't happen, but unlikely that it will get confiscated by customs. If anything, it would be more of an issue with USPS, but I can honestly say, they have delivered every perfume purchase I have made from overseas this year.
My recent split of Fate, got held up in customs. It was flagged for FDA approval for some odd reason. It was clearly marked as perfume. DHL was the transport company, not USPS.
