CBP 434 Forms, also known as Customs and Border Protection Form 434, are used for various purposes related to international trade and customs. These forms are primarily used to declare the origin of goods being imported into the United States or Canada and to claim preferential tariff treatment under certain trade agreements, such as the North American Free Trade Agreement (NAFTA) or the United States-Mexico-Canada Agreement (USMCA). The forms provide information about the origin, value, and classification of imported goods, which is important for customs officials to determine the appropriate duties, taxes, and trade benefits applicable to the goods.
