I have a relative that works for Homeland Security. Prior to that he worked for Customs and Immigration. He did a lot of work at Dulles Airport in the DC area. He told me that the fines for Cuban cigars could be as high as $10,000 for each cigar that you attempted to bring in. He also said that rarely were the fines assigned and most of the time the cigars were just confiscated. However, there were several times that travelers denied having Cuban cigars and then were found with a box or two in their luggage. These folks paid fines around $5,000. So beware. Although a lot of folks say no big deal, I would advise against trying to sneak them pass custums.
