Hi ladies. A co-worker of mine just returned yesterday from his honeymoon at Excellence Playa Mujeres (which he raved about). He and his wife went into the market in Cancun during their stay to do some shopping, and he bought some Cuban cigars. He asked the vendor, who was an American living in Cancun, about bringing Cuban cigars back into the US and was assured that the trade embargo had been partially-lifted. The vendor said Americans were allowed to bring in a maximum of 5 Cuban cigars for personal use back into the country.
Yesterday, on their way back through customs in Houston, he stated when asked on his customs form, that he had 5 Cuban cigars. Here's where the event could have gotten hairy! He and his new bride were escorted to a holding area and they were interviewed by a customs agent, who repeatedly explained that the no such "partial lifting" of the trade embargo existed. My co-worker did say the customs agents were nice about it, but all of his identifying information (passport, flight itinerary, driver's license) was copied and a report was filled out. The cigars were also confiscated, of course.
To make a long story short, despite the US government's ease of a few travel restrictions to Cuba, it is still illegal to bring Cuban cigars back into the US. Or, it's not advised to declare them on your customs form
