If you're traveling abroad this summer and unsure of what kind of souvenirs you are and are not allowed to bring back home to the U.S., here's a very useful link to the US Dept. of Homeland Security. They detail what items are restricted, which are openly permitted and those that are completely forbidden.
So if you want to ensure that you only purchase souvenirs abroad that are going to make it through customs and arrive home with you, check out this website for all of the details -
