U.S. Goods Returning
Goods manufactured in the United States that have been previously exported and are now returning require a formal declaration called American Goods Returned (AGR) also referred to as U.S. goods returning (USGR).
In this video, Aimee Miller, explains when an American Good Returned is eligible for duty-free treatment and the documents that are required.
Do not assume that the return of goods to the United States will be without some difficulty. A common mistake that importers make when declaring U.S. goods is that they do not know where the products were manufactured. Just because the product was purchased in the U.S. it doesn't necessarily mean it was manufactured in the United States.
