U.S. Customs is very particular about what they let in the country. Many people go on trips to other countries and buy souvenirs only to get them confiscated at customs. Before going on a trip overseas is would be wise to check for things that you cannot bring back to the states. Just because the rest of the world considers it to be legal doesn’t mean the U.S. does. Some of the things that are banned in the U.S. are for our own protection. Other times it doesn’t make since why some things are banned. Either that is the law and we must adhere to it. So next time you want to bring something back from overseas makes sure it isn’t anything on this list.
