The White House Just Named the Network — And Importers Are in the Crosshairs
On August 13, 2026, the Trump administration released a 25-page report that rewrote the conversation around tariff enforcement. Titled "The Great Transshipment Scam," the document — produced by the White House Office of Trade and Manufacturing Policy — publicly accused Chinese exporters and more than 40 third-country intermediaries of systematically routing goods through lower-tariff jurisdictions to disguise their Chinese origin before entering the United States. The stakes are enormous: billions of dollars in lost federal revenue, a new AI-powered enforcement system actively scanning your shipments, and a set of penalties that can compound fast enough to threaten a company's survival. Whether your business sources from Southeast Asia, Mexico, or any other manufacturing hub that has grown rapidly since 2018, this report demands your attention.
What the Report Actually Says
The Trump administration's report accuses Chinese firms of having systematically diverted goods through lower-tariff jurisdictions since the US kicked off its trade war with China in 2018. The methods documented are specific and varied. The report alleges that exporters use limited assembly, relabelling, repackaging, re-invoicing, and false country-of-origin declarations to disguise Chinese-origin products and secure more favorable tariff treatment on entry into the United States.
The White House Office of Trade and Manufacturing Policy accused dozens of countries of being part of China's "shadow transshipment network," sorting them "according to the scale of China-linked trade, the depth of their economic integration with China, and the weak-link advantages that make them susceptible to rerouting activity."
The countries named are not obscure. China's biggest enablers, according to the report, "range from Mexico and Canada on US land borders to the European Union, India, Japan, and South Korea." If your supply chain passes through any of these markets — and most global supply chains do — your shipments are operating in elevated-scrutiny territory.
The Numbers Behind the Scam
The report includes a range of estimates for the scale of transshipments to avoid tariffs, citing government and private-sector numbers to estimate roughly $34.2 billion to $303 billion of goods transshipped each year. It used a central figure of $75 billion worth of goods being transshipped to estimate how much in tax revenues have been lost.
According to the report, these transshipments result in the loss of 450,000 U.S. jobs, a $113 billion to $150 billion reduction in annual GDP, and $19 billion to $26 billion in lost federal revenue. For context, earlier analysis by Goldman Sachs had already flagged the scale of the problem: Goldman Sachs warned that export data indicated increased rates of transshipments from China to the US through third-party countries — a similar pattern observed during the 2018 trade war — and that the evasion taking place could impact more than $200 billion in US imports.
The White House was blunt in its framing. "Illegal transshipment is not just a technical customs violation. It is a deliberate attempt to evade US tariffs, undercut American workers and manufacturers, and deprive the American people of billions of dollars in revenue," said Treasury Secretary Scott Bessent.
The AI Detective Border: How Enforcement Actually Works Now
The report is not just an accusation — it is a blueprint for a new enforcement era. The tools being deployed include an AI-powered "detective border" that will scan shipment data against routing histories, confirm production capacity and ownership relationships, and even analyze packaging patterns and X-ray imaging at ports to detect mismatches between what is declared and what is actually in a container.
U.S. Customs and Border Protection has moved beyond traditional, paper-based risk targeting and now uses advanced data scoring systems to detect anomalies in import data, trace potential transshipment routes, and connect supplier networks tied to forced labor. The AI system does not need to catch outright fraud to create problems for your business. Origin patterns consistent with transshipment through third countries, sudden shifts in country of origin for the same product from the same supplier, or declared origins inconsistent with the supplier's known manufacturing footprint can all trigger flags — and the AI system does not need to identify fraud; it flags statistical anomalies and inconsistencies.
When an importer has been found to have falsified the origins of a good, its imports can be retroactively tariffed going back roughly a year. That retroactive exposure can turn a manageable compliance issue into a company-defining liability.
The 40% Penalty Tariff and Compounding Consequences
Beyond retroactive duties, there is now a structural penalty designed to make transshipment economics unworkable. An executive order provision authorizes CBP to impose a 40% tariff penalty on any good it determines has been transshipped to avoid tariffs. That penalty stacks on top of whatever the actual country-of-origin tariff rate would have been. In addition to the 40% penalty tariff and the tariff due from the good's actual country of origin, CBP may impose fines under 19 U.S.C. § 1592 and pursue claims under the False Claims Act for false country-of-origin import declarations.
Penalties under this provision cannot be reduced under standard administrative processes, which reflects CBP's shift to stricter enforcement. Meanwhile, in the first six months of fiscal year 2025, CBP issued 1,400 trade enforcement penalties, and recovered $192.77 million by June 30, already surpassing the entire FY2024 total of $117.7 million. The enforcement trajectory is clear and steep.
The Real Risk for Legitimate Importers
Here is the part that many compliance teams miss: you do not have to be knowingly evading tariffs to face consequences. If a supplier misleads or engages in transshipment, the U.S. importer will be on the hook to CBP. Even importers following historical practices — such as relying on supplier statements without thorough documentation — may now face severe penalties.
This is particularly true for importers sourcing from countries with known transshipment risk, including Vietnam, Malaysia, Cambodia, Thailand, and Indonesia. The surge in Chinese exports to those markets is well-documented. Asia experienced a surge in imports from China in recent weeks, growing at an average of 21.7% year over year in March-April 2026, up from 17.3% in February, according to an analysis by Nomura, which said transshipments were flowing through Vietnam, Thailand, Malaysia, and India.
The practical implication is that any importer sourcing from these regions who cannot produce airtight origin documentation is exposed — not because they are cheating, but because CBP's AI-driven systems cannot distinguish between an honest sourcing shift and a transshipment scheme without that documentation in place.
Beyond transshipment, the Department of Justice is increasingly using the False Claims Act to pursue civil penalties against importers accused of undervaluation, misclassification, or evasion of Section 301 and 232 duties. Civil and criminal exposure is growing, including use of the False Claims Act with treble damages and parallel criminal prosecutions.
What Compliant Importers Should Do Right Now
The enforcement environment demands proactive action, not reactive scrambling. The first priority is origin documentation. Importers should revisit country-of-origin certifications; if suppliers cannot produce signed, dated documentation substantiating origin, importers may be exposed regardless of whether the U.S. company is actually the importer of record.
Supply chain mapping is the second imperative. For importers who have shifted sourcing from China to Vietnam, Malaysia, Thailand, or Mexico in response to Section 301 tariffs, the origin documentation supporting the shift must be airtight. CBP will look at your sourcing history and compare it to what you are declaring today.
CBP is also expected to publish a biannual list of countries and facilities associated with circumvention schemes, which importers should assess to make risk decisions involving supply chains and procurement. Monitoring that list will become a routine compliance task.
Finally, consider voluntary prior disclosure. Under CBP's prior disclosure program, an importer that identifies a customs violation and voluntarily discloses it to CBP before a formal investigation begins receives dramatically reduced penalties. If a review of your supply chain uncovers something that looks questionable, early disclosure is almost always preferable to waiting for CBP to find it first.
