Section 337 of the Tariff Act

Section 337 of the Tariff Act allows U.S. Customs and Border Protection (CBP) to investigate and take action against imports that infringe on U.S. intellectual property rights, such as patents, trademarks, or copyrights. If the CBP finds that imported goods violate these rights, they can block or seize the shipments from entering the country. This process helps protect U.S. inventions, brands, and creative works from being copied or illegally imported, supporting innovation and fair competition.
