I’m currently in Poland for a conference, and I had the idea to bring some żubrówka (bison-grass vodka) back home to the United States with me as a unique souvenir. However, the Wikipedia page linked above says that importation of this spirit into the USA is not allowed due to its coumarin content.
Do these regulations apply only to commercial import for resale, or are tourists banned from bringing the liquor home for personal use as well? If I have a bottle of żubrówka in my luggage on return to the USA, do I risk having it confiscated? Being fined? Imprisonment? (OK, I don’t really think that last option is really on the table.)
