šWhat the White House's "Great Transshipment Scam" Report Means for U.S. Importers
Summary: The White House has published The Great Transshipment Scam: Rise, Scope, and Costs, a report on the challenges of illegal transshipment, country of origin fraud, and tariff evasion in international trade. It highlights enforcement agencies' focus on detecting tariff evasion through false origin declarations, minor processing, and complex supply chains. For importers, manufacturers, and customs professionals, the report offers insights into future customs approaches to origin verification and supply chain transparency. |
Why Origin Matters More Than Ever

A Certificate of Origin remains an important customs document, but the report suggests that customs authorities are likely to look well beyond the certificate itself.
According to the report, enforcement increasingly focuses on whether goods have genuinely undergone substantial transformation, rather than simply being:
Relabelled
Repackaged
Re-invoiced
Subject to minor processing
Accompanied by revised documentation
Where these activities do not amount to substantial transformation, claims regarding country of origin may receive closer scrutiny.
For businesses, this reinforces an important principle: country of origin claims should always be supported by robust manufacturing records and evidence demonstrating how origin was determined.
Documentation Should Tell a Complete Story

Commercial invoices, packing lists and transport documents remain essential, but increasingly they may represent only part of the evidence customs authorities expect to see.
A well-prepared importer should be capable of demonstrating a consistent audit trail covering:
Supplier sourcing
Manufacturing activities
Production records
Material inputs
Shipping movements
Commercial transactions
Payment records
When documentation presents a clear and consistent picture of the supply chain, businesses are generally better positioned to respond efficiently to customs enquiries and post-clearance audits.
Data Analytics Are Transforming Customs Enforcement

Perhaps one of the most significant themes within the report is the growing role of technology in customs enforcement.
The report discusses the use of:
Data analytics
Routing analysis
Production capacity assessments
Ownership mapping
AI-assisted risk targeting
Trade pattern analysis
These tools are intended to help customs authorities identify unusual trading patterns before physical inspections even occur.
For compliant businesses, this means enforcement is becoming increasingly intelligence-led rather than inspection-led.
Understanding Substantial Transformation
Determining the correct country of origin is rarely as straightforward as identifying where a shipment was exported.
In many cases, customs authorities consider whether manufacturing activities carried out in a country resulted in a substantial transformationĀ of the product.
Simply carrying out activities such as:
Packaging
Sorting
Simple assembly
Relabelling
Administrative processing
may not be sufficient to establish a new country of origin for customs purposes.
Importers should therefore ensure that origin determinations are based on the applicable customs rules and supported by appropriate documentation.
Strong Supply Chain Governance Is Becoming a Competitive Advantage

The report also highlights the growing importance of understanding supply chains beyond immediate suppliers.
Importers should consider whether they have sufficient visibility over:
Manufacturing locations
Production capacity
Component sourcing
Related-party relationships
Logistics routes
Supporting customs documentation
Maintaining this level of visibility not only supports customs compliance but can also improve risk management and supply chain resilience.
Practical Steps Businesses Can Take
In light of the report, businesses may wish to review whether they can readily demonstrate the basis for their customs declarations.
Consider reviewing:
Country of origin determinations
Supporting manufacturing documentation
Supplier due diligence procedures
Record-keeping practices
Customs valuation documentation
Internal compliance procedures
Post-clearance audit readiness
Being prepared before questions arise is generally more effective than attempting to reconstruct documentation during a customs enquiry.

Final Thoughts
The White House report does not suggest that every international transaction is problematic. Rather, it signals that customs enforcement is becoming increasingly sophisticated, data-driven and focused on verifying the substance behind customs declarations.
For importers, the message is clear: maintaining accurate origin analysis, comprehensive documentation and transparent supply chain records is becoming an increasingly important part of effective customs compliance.
Businesses that invest in strong customs governance today will be better positioned to respond confidently to tomorrow's enforcement environment.
