I'd love to offer an answer but my last experience with French customs was when, due to a medical reason, I had to postpone a trip back to the states after checking in @ CDG.

The next morning, after being reticketed, I was told to go into the customs area to the AA baggage desk to get my baggage in order to re-check-in.

Picking up the baggage was no problem, but on the way out I was stopped by French Customs.. who searched my bag even though it had never left France!
