De acordo com as NOS Alfândega e Proteção de Fronteiras :
As a visitor to the United States what are my exemptions on gifts for family and friends?
As a non-resident, you are allowed up to $100 worth of merchandise, free of duty and internal revenue tax, as gifts for other people. To claim this exemption, you must remain in the United States for at least 72 hours, and the gifts must accompany you.
This $100 gift exemption, or any part of it, can be claimed only once every six months. You may include 100 cigars within the gift exemption, but alcoholic beverages may not be included. The cigars may not be of Cuban origin.
A alfândega não se importará com esses presentes. A TSA também não se importará com eles, já que não parecem remotamente armas.
