What is IOR Qualification? US Customs Clearance Requirements

In February 2026, CBP launched a special review operation codenamed "5H." In that month alone, 3,826 export containers triggered 5H inspections, with a return rate as high as 82% to 87%. The core reason was the falsification of importer qualifications. Following this, US Customs further clarified the new customs clearance regulations:

Starting March 20, US Customs will comprehensively tighten the supervision of IOR (Importer of Record) and Bond (Customs Bond), focusing on cracking down on gray-area customs clearance practices. IOR numbers with false information or ambiguous clearance entities will be invalidated in batches. The core purpose of this move is to completely clean up the large number of "shell companies" and fake IORs that existed in the past, putting an end to the era of "double-clearance tax-inclusive" logistics. The practice of borrowing numbers for clearance where the entity does not match will directly trigger a 5H inspection. Violators face serious consequences such as cargo detention and return.

Therefore, in the face of the implementation of the new regulations, customs clearance must achieve 3 "Musts":

• Must be Clear: Importer of Record (IOR) — The legal entity responsible for the import; only an operating US entity is legitimate.

• Must Hold: Employer Identification Number (EIN) — The unique identification proof from the tax bureau; it is a standard requirement for IOR and cannot be borrowed.

• Must Possess: Customs Bond — A necessary guarantee for customs entry; smooth clearance is only possible after a compliant purchase.

For export enterprises, this is a compliance transformation that must be completed. This article will take you through an in-depth analysis of how to complete the IOR qualification self-inspection under the new regulations to help you clear customs smoothly.

What is IOR Qualification?

First, we must clarify what role IOR qualification plays in customs clearance:

• As the Responsible Entity: The IOR is the legal import entity recognized by US Customs, bearing all legal responsibilities for cargo import declaration, tariff payment, and compliance inspection. If any problems occur during the import process (such as false declaration, unpaid tariffs, or cargo violations), Customs will directly hold the IOR accountable.

• As an Identity Marker: The IOR is the unique identification of the importer in the US Customs system, usually reflected in the form of an IOR number or the corresponding tax number (EIN, Employer Identification Number). Whether it is a local US company or a foreign enterprise, if they want to import goods into the United States, they must clearly designate an IOR entity.

• As Information Proof: According to US Customs regulations, all formal imported goods (value ≥ $2,500) must have a valid IOR. The IOR must ensure that its information (such as company name, address, tax number, etc.) is accurate and authentic in the customs system, and regularly updated to maintain the validity of the IOR status.

Key Interpretation of the "New Regulations"

Secondly, we need to understand what changes these new regulations bring. The core of this new regulation lies in "ending the non-resident importer loophole," requiring that the IOR must be a verifiable, responsible, and uniquely authentic US entity:

• Authenticity of the Entity: Abolish all virtual, shared, and affiliated IOR numbers. The IOR must be a physical US company with a real address and employees. Offshore shell companies are no longer allowed. The IOR must be completely consistent with the Bond and POA entity. "Borrowing numbers for clearance" is strictly prohibited.

• Penetration of Responsibility: Importers need to be responsible for all links in the supply chain, especially involving "mixed origin" goods (such as Chinese products processed in Mexico).

• Closed-Loop Documentation: A complete chain of evidence matching capital flow and logistics must be established (bank remittance records, procurement contracts, full-process logistics documents, etc.); having only invoices is not enough.

• Severity of Punishment: False declarations and illegal operations can lead to the rejection of declarations, cargo detention, and cancellation of the IOR/Bond, and may even trigger massive civil claims or criminal fraud lawsuits.

The IOR number invalidation policy is not an isolated regulatory action but forms a strong superposition with the previously escalating 5H inspection storm. The 5H inspection (i.e., Entry Processing Hold) is a strengthened review mechanism by CBP targeting the authenticity and compliance of declaration information. Led by the newly established rapid document review department, it adopts a combination of system screening and manual review to conduct in-depth, ticket-by-ticket reviews of declaration materials such as commercial invoices, packing lists, and manifests. Once anomalies are discovered, the cargo clearance process is frozen immediately, and in severe cases, mandatory return is enforced.

Therefore, aside from doubts regarding the qualifications of the IOR entity, whether the declaration information is true and accurate also practically affects whether customs clearance can proceed smoothly.

IOR Qualification Verification Requirements

1. IOR Entity Qualification Requirements

• Local US Enterprises: Must be a legally registered company or LLC, possess a physical address, full-time employees (required by the trend of the new policy), and hold an Employer Identification Number (EIN) issued by the Internal Revenue Service (IRS).

• Overseas Enterprises (e.g., Chinese companies): Cannot act directly as an IOR. They must register a US company or entrust a licensed US customs broker to handle IOR qualifications and submit guarantees to ensure compliance in customs clearance:

• Method 1: Register a company in the US, obtain an EIN tax number, and apply for an IOR as a US entity.

• Method 2: Entrust a compliant local US IOR agent, sign a Power of Attorney (POA), and have the agent assume the IOR responsibility.

• Individual Importers: Must be US citizens or lawful permanent residents, using a Social Security Number (SSN) as identification, but this only applies to small-value non-commercial imports.

2. Essential Documents for IOR Qualification Verification

• A completely filled-out CBP Form 5106 (Importer Identity Form); information must be authentic, accurate, and verifiable.

• Provide a government-issued photo ID (such as a passport or driver's license) for identity verification.

• EIN verification documents issued by the IRS (such as a 147C Letter, CP-575 Letter, Form 1040, Form 941, etc., are all acceptable).

• Provide a valid Power of Attorney (POA) signed with a licensed customs broker, clarifying the scope and validity period of the authorization.

How to Respond to the New Regulation Qualification Verification?

Before qualification verification, it is necessary to confirm who will act as the responsible IOR entity:

The Buyer as the Responsible Entity

In this scenario, the US buyer/consignee generally acts as the IOR entity. However, as an importer, you should also be alert to situations where the buyer's IOR becomes invalid or changes. Any adverse factors may lead to clearance failure. Therefore, we recommend that importers ask the buyer to provide the following during the order confirmation stage:

• Their IOR number;

• A recent CBP Form 7501 (Entry Summary) as proof that the IOR is in use;

• Their Continuous Bond number.

The Importer as the Responsible Entity

• Immediately Self-Check IOR Qualifications: Confirm that the IOR is a real US operating entity and that the EIN (Employer Identification Number) is a valid tax number registered with the IRS. Additionally, you must hold a Customs Bond purchased under that EIN. Affiliation or sharing is strictly prohibited; ensure that the entities and information for the IOR, EIN, and Bond are entirely consistent and matching.

• Complete the Form 5106 Update: Contact your customs broker to confirm whether the CBP Form 5106 has been submitted for an update, and ensure that the company name, address, and EIN registered on the CBP Form 5106 are completely identical to the IRS records.

• Confirm BOND Validity: Confirm the applicable type of the customs clearance Bond, whether it is still within its validity period, and whether the amount matches the actual import volume.

• Avoid Using "Double-Clearance Tax-Inclusive" Services: Self-check whether there are situations of "sharing IOR qualifications," "affiliating with shell IORs," or "forging and stealing IORs." You must say goodbye to the "double-clearance tax-inclusive" model and switch to a disciplined compliance model of "single-ticket single-clearance, closed-loop trade."

• Reserve Supply Chain Traceability Documents: For high-value or sensitive products, prepare supply chain traceability documents in advance according to CBP requirements (raw material procurement certificates, payment receipts, production records, etc.), so they can be quickly submitted within the 30-day window after cargo detention.

TIPS:

If you entrust a local US IOR agent to handle things on your behalf and assume IOR responsibility, be sure to regularly verify: whether the cooperating licensed US customs broker is still valid, and whether the Power of Attorney is within its validity period. If the period is exceeded, it may also cause clearance failure, leading to cargo detention and return.

The implementation of the new IOR qualification regulations means that the future import model of the United States will gradually move closer to that of Europe, shifting from "managing goods" to "managing people," and holding specific entities accountable. This move marks a new, stricter, and more standardized stage in the verification of customs clearance information. It is recommended that relevant practitioners familiarize themselves with the new regulatory requirements as soon as possible to ensure their own compliance.
