CBP to Enhance IOR Verification from September 18: Risks for U.S.-Bound Shipments

U.S. Customs and Border Protection(CBP) will roll out stricter verification for Importer of Record(IOR) information from September 18, 2026. Any inaccurate, outdated or fake details submitted on CBP Form 5106 may lead to immediate IOR number cancellation, blocking cargo customs clearance.

CBP will audit IOR’s legal name, tax ID, physical business address, contact information and authorized customs broker paperwork. Virtual addresses commonly adopted by small U.S. buyers become a high-risk target. For international exporters, invalid IOR records can trigger cargo detention, demurrage fees, order cancellations and damaged buyer relationships, especially for shipments using third-party IOR services.

Exporters should urgently validate all U.S. importer records before the enforcement date. Review power-of-attorney documents and flag cargo arriving in the U.S. after September 18 for extra compliance checks. Clarify IOR liability within sales contracts and prepare backup importer solutions for time-sensitive shipments.

This enforcement marks CBP’s push for greater supply chain transparency. Exporters that integrate IOR due diligence into routine order workflows can effectively avoid costly customs disruptions when selling into the U.S. market.
