The purpose of this legislation, known as the Closing the De Minimis Loophole Act, is to eliminate a specific provision in the Tariff Act of 1930 that allows certain low-value imports to enter the United States without paying tariffs or duties. This change aims to enhance revenue collection and improve enforcement of trade laws. The key provisions of this law involve the removal of the de minimis treatment, which currently allows goods valued at $800 or less to enter the U.S. without tariffs.
