I would never smuggle contraband or want other people to do it either. But one time I was flying back from Canada, and the guy in the seat next to me was not shy about his critical mission to hand deliver 5000 parts from one of the major capacitor manufacturers, directly to a plant in Mexico that was suffering a shortage. This has to be carry-on, checking them as baggage is not an option. What are the odds, this can't be that uncommon. I think people would pay extra for a foreign manufacturer or distributor to courier the essential package ASAP and handle the paperwork no differently than the way they have been doing it for others.
