Story 1 — Executive Order | Strengthening Customs Enforcement
President Trump Signs Executive Order Overhauling Customs Enforcement — Brokers, IORs, and Penalties All Affected
On June 3, 2026, President Trump signed the Executive Order on Strengthening Customs Enforcement, representing the most comprehensive reform of U.S. customs enforcement in decades. The order imposes sweeping requirements on importers of record, customs brokers, freight forwarders, and custodians of bonded merchandise, with implementation deadlines of 90 and 180 days from June 3, 2026.
IOR Reforms (180-day deadline — December 1, 2026): CBP must require minimum tangible domestic assets and/or bonding; beneficial ownership and import volume disclosures; risk-based IOR tiers; and IOR “good standing” standards. IORs found to have imported fentanyl, nitazenes, or contraband will be barred.
Foreign IOR Restrictions: Foreign IORs are prohibited from filing informal entries under 19 U.S.C. 1498. For formal entries, foreign IORs must be CTPAT-validated or use a CTPAT-validated licensed customs broker.
Broker Enforcement: Maximum penalties for brokers who fail due diligence or repeatedly represent noncompliant clients. Minimum penalty floor of 50% of assessed penalty. No mitigation for repeat offenders.
Disclosure Requirements (90-day deadline — September 1, 2026): Supply chain certifications under CAATSA and 18 U.S.C. 545; foreign tax and global business identifiers; manufacturer product identifiers; and foreign exporter documentation.

Story 3 — Litigation | IEEPA Refund Appeal Filed
Government Files Federal Circuit Appeal — Stay Motion Expected; All CAPE Payments at Risk
On June 2, 2026, DOJ appealed the CIT’s universal IEEPA refund injunction to the Federal Circuit. DOJ’s motion to prevent Commissioner Scott’s June 9 testimony was denied. A Federal Circuit stay motion is expected imminently. If granted, all CAPE payments halt — including accepted declarations already in the refund queue. CBP is currently processing approximately $85 billion in refunds through CAPE Phase 1. Finally liquidated entries (180+ days post-liquidation) are not covered by CAPE under CBP’s current position.
