A Voided IOR Number Stops Cargo at the Gate: US Customs Is Now Checking Who You Are
On 3 June 2026 the United States signed Executive Order 14411, titled Strengthening Customs Enforcement. From 18 September, US Customs and Border Protection began applying its provisions on importer identity: new and existing importers of record now face substantive verification of the information filed on CBP Form 5106, and inaccurate, incomplete or unverifiable data can lead to the IOR number being voided outright. Once voided, that number cannot be used for any entry.
What gets checked is unremarkable: the fields on the form and in the file. Importer name, IRS employer identification number or social security number, mailing address, physical operating address, telephone, email. CBP states in its notice that importers, or the brokers filing on their behalf, must provide accurate and complete information, and that it will go on to revise importer eligibility regulations and guidance. An earlier round on 20 March 2026 voided a batch of numbers that could not be verified, with the requirement that new entries use a real, verifiable IOR.
The weight of this is easily buried under the word tariff. Tariffs affect cost. The IOR affects eligibility. A high tariff can be negotiated, passed through, repriced. A voided number means the entry is rejected in the system, the cargo cannot clear, and it stays at the port. Storage, demurrage and warehousing accrue every day the vessel sits there, and the fix is not paying a bill. It is resubmitting documents and waiting for reinstatement, or in rare cases re-exporting.
Risk clusters in a few structures. First, cargo booked on a delivered-duty-paid basis where a third party supplies the importer of record: the importer is often not the actual buyer, the address is virtual, and the number and the bond are shared. Second, long-standing importers who never updated their file, whose address, phone and contact have changed while the form still reflects a version from years ago. Third, non-resident importers with no physical US premises, for whom the operating address is the hardest field to substantiate. All three used to pass. They no longer do.
For the cargo A-Choice handles, this has concrete weight. Non-ferrous metals and project cargo carry high value per shipment, so a box stuck at the port costs far more in storage and liquidated damages than the freight ever did. Fertilisers run on an application calendar, and missing the window does not mean a few days late, it means the next season. Energy products involve dangerous goods and storage conditions, where delay is more expensive still. What these cargoes fear is not price. It is uncertainty.
The first action is to check shipment by shipment. Before export, verify five things about the importer: the name matches the registration document, the tax number can be verified, both mailing and operating addresses reconcile, and the phone and email are real and on a corporate domain. The broker's power of attorney must be signed directly by the importer. Arrangements routed through a third party's authorisation are not accepted under the current reading.
The second is to write into the contract who supplies the importer entity. FOB, CIF and DDP draw very different lines here. On DDP terms, the confirmation should state who provides the IOR number and who bears storage and rebooking costs if it fails. Do not assume destination clearance is simply the other side's problem.
The third is not to share a bond. Shared bonds, borrowed bonds and one bond covering multiple importers are the easiest pattern to spot in this round of verification, and the hardest to explain once a number is voided. The fee saved buys the risk that a shipment never clears.
The fourth is to build in clearance buffer. Allow three to five days before arrival for supplementary filings, and keep Form 5106, photo identification, tax number verification and the authorisation letter in a package that can be submitted on demand. CBP maintains a dedicated mailbox for reinstating voided numbers, but reinstatement takes time, and the vessel does not wait.
Reading this as a one-off enforcement action understates it. The executive order calls for confirming the compliance status of existing importers and for revising importer eligibility rules. The direction is from documentary review to substantive verification. For exporters, the importer of record is shifting from a field that can be borrowed to a qualification that has to be held. That shift will not reverse when one round of checks ends.
