The "End China's De Minimis Abuse Act" aims to curb the flow of de minimis shipments from China into the U.S., close a loophole China was using to avoid Section 301 tariffs, and prevent future abuse of de minimis to avoid U.S. trade regulations. The act adjusts the review rules for de minimis entry of Chinese goods, raises the exemption threshold and barriers, and establishes new penalties for violations.
