CBP Tightens IOR Enforcement: What Global Sellers Need to Know

U.S. Customs and Border Protection (CBP) has begun placing greater emphasis on the accuracy and completeness of Importer of Record (IOR) information, signaling a more rigorous approach to importer data and customs compliance.

The enhanced enforcement follows a CBP notice published in the Federal Register in August 2026. Beginning September 18, 2026, CBP may void an IOR number when information submitted through CBP Form 5106 is determined to be inaccurate or incomplete.

For businesses importing goods into the United States, the development highlights an increasingly important element of global trade compliance: keeping importer information accurate, complete, and current.

What Is an Importer of Record?

An Importer of Record (IOR) is the individual or entity responsible for ensuring that imported merchandise complies with applicable U.S. customs requirements.

When establishing or updating an IOR, businesses generally provide information through CBP Form 5106, including the importer’s:

• Legal name
• Tax identification number
• Mailing address
• Physical address
• Telephone number
• Email address
• Other information required by CBP

CBP's recent enforcement places particular emphasis on the reliability of this information and its direct association with the IOR.

If CBP determines that the information associated with an IOR is inaccurate or incomplete, the agency may take action against the IOR number. A voided IOR number cannot be used to enter merchandise into the United States.

For importers, this means that information that may once have been treated as a routine administrative matter can potentially become a customs-entry issue.

Why Does IOR Accuracy Matter to Global Sellers?

For global sellers, customs compliance does not begin when a shipment arrives at a U.S. port—and it does not end when a product is listed on an e-commerce platform.

Depending on the product, transaction structure, and supply chain, businesses may need to manage requirements relating to:

• Importer of Record information
• Customs entry documentation
• Tariff classification
• Customs valuation
• Duties and tariffs
• Country-of-origin requirements
• Product-specific regulations
• Licenses, permits, and certifications
• Intellectual property rights
• Import restrictions and other regulatory requirements

These obligations can become increasingly complex as a company expands its product portfolio or enters additional markets.

A change in corporate information, business address, importer structure, or supply-chain arrangement may also create compliance considerations that extend beyond a single shipment.

Compliance Is Becoming an Ongoing Responsibility

The latest IOR enforcement is part of a broader trend in which customs compliance increasingly depends on the quality of the underlying data.

An outdated address may appear to be a minor administrative problem. An incomplete importer record may initially seem unrelated to the merchandise itself.

But for an importer, the information connecting the company, its customs entries, its products, and its supply chain is increasingly part of the compliance framework.

The challenge for global sellers is therefore not simply understanding the rules.

It is keeping up with them.

For companies managing dozens, hundreds, or thousands of products across multiple markets, monitoring regulatory requirements manually can become difficult, time-consuming, and increasingly vulnerable to gaps.

From IOR Data to Global Trade Compliance

IOR information is only one piece of the broader compliance picture.

A product entering the United States may raise questions involving tariffs, customs classification, country of origin, intellectual property, licensing, product regulations, documentation, and certifications.

These requirements can also change over time.

For global sellers, the challenge is therefore increasingly one of continuous compliance management: identifying relevant requirements, connecting them to specific products and markets, and monitoring regulatory changes that may affect future transactions.
