The Import Security and Fairness Act aims to update and clarify rules regarding the importation of goods into the United States, specifically focusing on the de minimis treatment under the Tariff Act of 1930. The main goal is to enhance security and fairness in the import process by establishing additional requirements and exceptions. One of the key provisions of this Act is the introduction of new exceptions to the existing de minimis threshold, which allows certain low-value imports to enter the U.S. without paying duties or taxes.
