President Trump’s June 3, 2026 Executive Order on customs enforcement signals a significant expansion of the Administration’s America First Trade Policy beyond tariffs and trade remedies. The order directs the Department of Homeland Security and U.S. Customs and Border Protection (CBP) to undertake a broad range of reforms aimed at strengthening customs enforcement, including heightened importer vetting, increased bond requirements, expanded supply-chain disclosure obligations, and stricter penalties for noncompliance. The order also focuses on nonresident importers of record, imposing new restrictions that could affect foreign companies that have long relied on established import structures and procedures to access the U.S. market. Because many of the contemplated changes can be implemented through CBP rulemaking and guidance rather than legislation, importers should expect significant regulatory developments over the coming months. Companies that import goods into the United States should begin assessing the potential impact on their customs compliance programs, supply chains, and import operations.
