Sellers importing inventory into the United States face increased compliance scrutiny as U.S. Customs and Border Protection moves ahead with verification of Importer of Record information. Amazon is urging affected sellers to review their customs records carefully, warning that inaccurate information could put their ability to import goods into the U.S. at risk.
In an update posted on Seller Central, Amazon said CBP began verifying six fields associated with Form 5106 on September 18. Incorrect records could result in an Importer of Record, or IOR, number being voided, potentially disrupting shipments entering the United States.
Amazon has also scheduled a live webinar for October 8 to help sellers understand the changes and prepare their import operations.

What Amazon Sellers Need to Know About the New IOR Checks
An Importer of Record plays a critical role in bringing goods into the United States. The IOR is responsible for ensuring that imported goods comply with applicable customs requirements and that required duties, taxes and documentation are properly handled.
Amazon said the latest enforcement follows its earlier guidance related to Executive Order 14411. Sellers had previously been encouraged to review their customs arrangements and confirm their IOR status. With enforcement now underway, sellers should treat the issue as an active compliance matter rather than simply an upcoming change.
According to the Seller Central announcement, CBP is verifying six fields on Form 5106. Amazon warned that inaccurate information could lead to an IOR number being voided and interrupt the seller's ability to bring inventory into the U.S.
Why This Matters for Amazon Sellers
For sellers that manufacture or source products outside the United States, problems with an IOR can affect the wider inventory supply chain.
If an IOR number becomes invalid, affected shipments could face customs complications and inventory replenishment could be disrupted. For FBA sellers, any extended interruption in inbound inventory can create additional business problems, particularly when stock is already running low.
Sellers should therefore review their customs setup before arranging future U.S.-bound shipments rather than waiting for an issue to arise at the border.
Amazon Highlights Risks Around Shell IOR Arrangements
Another important focus of Amazon's upcoming webinar will be the use of shell IOR arrangements. Amazon said the session will address risks associated with such arrangements and discuss best practices for establishing a single, trusted IOR relationship with U.S. customs.
This makes the webinar particularly relevant for international sellers who rely heavily on freight forwarders, customs brokers, sourcing agents or other third parties to arrange imports into the United States.
Sellers should understand who is actually acting as the Importer of Record for their shipments and ensure that the corresponding information is legitimate, current and consistent.
Amazon Webinar Scheduled for October 8
The webinar, titled "One IOR, One Strategy: Navigating EO14411 Without the Shell Game," is scheduled for October 8 at 9 a.m. Pacific Time. Amazon said the live session will cover the enforcement timeline, the six Form 5106 fields being audited, risks associated with shell IOR arrangements and recommended practices for establishing a trusted IOR relationship with U.S. customs. Sellers will also have an opportunity to ask questions during the session. The session is intended for sellers of all experience levels who import products into the United States.
What Sellers Should Do Now
Sellers importing goods into the U.S. should review their existing IOR arrangements and confirm that the information connected with their customs records is accurate. They should also speak with their customs broker, freight forwarder or import compliance professional where necessary to confirm how their IOR is structured and whether Form 5106 information remains current.
Particular attention should be given to situations where sellers are unsure whose IOR number is being used or where an intermediary has arranged an IOR on their behalf. Amazon's webinar can also help sellers understand the enforcement process and identify questions they may need to raise with their logistics or customs partners.
Sellers should avoid making assumptions about their compliance status solely because previous shipments cleared U.S. customs successfully. Amazon's announcement indicates that CBP verification is now actively moving forward.
How Sellers Can Benefit
For Amazon sellers dependent on imported inventory, understanding these requirements can help reduce the risk of customs-related disruptions, delayed replenishment and potential stockouts. The October 8 webinar also gives international sellers an opportunity to better understand the relationship between Form 5106, their IOR status and their broader U.S. import strategy.
With CBP verification already underway, sellers should consider reviewing their IOR information before their next shipment rather than waiting for a customs problem to expose inaccurate records.
Amazon has positioned the October 8 session as practical guidance for sellers navigating the new enforcement environment. For businesses that regularly send inventory into Amazon's U.S. fulfillment network, keeping IOR and customs information accurate can now be an important part of protecting inventory continuity and avoiding preventable disruptions at the border.
