U.S. Customs and Border Protection is no longer treating transshipment as a niche compliance footnote. In August 2026, the White House Office of Trade and Manufacturing Policy released a 25-page report, informally dubbed “The Great Transshipment Scam,” naming more than 40 countries as high-risk rerouting hubs for Chinese-origin goods and estimating that between $60 billion and $75 billion in merchandise is being funneled through third countries every year to dodge U.S. tariffs. Backing the report is real enforcement muscle: Executive Order 14411, signed on June 3, 2026, tightened importer-of-record requirements, bonding obligations, and ownership-disclosure rules, while CBP’s new “Detective Border” analytics platform now cross-references declared origins, routing histories, and component content at a scale no customs broker could match manually.
For freight forwarders, importers, and the factories behind them, the practical question is no longer whether CBP is looking harder at transshipment — it clearly is — but whether your own supply chain would survive that scrutiny if it were examined tomorrow. Waiting for a CBP Form 28 request for information, or worse, a raid referral from the Trade Fraud Task Force, is the expensive way to find out. Running your own audit first is the cheap way. This article walks through what transshipment actually means under U.S. law, where the exposure typically hides, and a practical framework for auditing your own network before an enforcement letter forces the issue.
Why Transshipment Has Become CBP’s Top Enforcement Priority
The scale of the enforcement build-out is hard to overstate. Congress has funneled roughly $4 billion toward CBP to add 8,500 new personnel, and the Department of Justice has designated tariff evasion a high-impact enforcement priority, standing up a cross-agency Trade Fraud Task Force with the Department of Homeland Security in August 2025. Whistleblower activity has followed the money: complaints about alleged duty dodging rose 160 percent year over year between March and May of 2025 alone, and the False Claims Act now sits alongside the traditional Section 1592 penalty framework, meaning a disgruntled employee or an underbidding competitor can trigger a federal investigation and collect a share of any recovery.
The numbers back up the rhetoric. In the first half of fiscal year 2025, CBP issued around 1,400 trade enforcement penalties, putting the agency on pace to exceed every prior year’s total, and recovered $192.77 million by June 30 — already ahead of the entire fiscal year 2024 recovery of $117.7 million. Comparing enforcement activity before and after the current administration took office, CBP reports that shipments flagged for post-release discrepancies rose 245 percent, with associated revenue assessments jumping from $9.6 billion to $25.8 billion. This is not a temporary campaign; it is a structural shift in how customs enforcement is staffed, resourced, and litigated, and it is squarely aimed at the transshipment channel.
What Counts as Illegal Transshipment Under U.S. Customs Law
CBP and the courts generally apply a “substantial transformation” test to decide a product’s true country of origin: goods only earn the origin of the country where they were transformed into a new and different article with a distinct name, character, or use. Simply routing a finished product through a third country, repackaging it, swapping a label, or performing light assembly that does not meaningfully change the product does not change its origin for tariff purposes — even if the paperwork says otherwise.
The White House’s own August 2026 report describes illegal transshipment broadly, covering relabeling, repackaging, re-invoicing, minor processing, and outright false country-of-origin declarations, any of which can be used to secure duty treatment that would not apply if the good’s true economic origin were disclosed. Notably, CBP has signaled it will not extend the same mitigation and remission relief to transshipment penalties that it historically offered for other classification or valuation errors, which removes one of the standard off-ramps importers have relied on when a mistake surfaces during an audit.
This matters because “transshipment” is not limited to shipments that were deliberately structured to deceive. An importer who genuinely did not know that a supplier’s component sourcing had shifted, or that a third-country facility performed only cosmetic processing, can still be exposed to penalties, entry reliquidation, and reputational damage. Intent affects the severity of the penalty, not whether a violation occurred, which is exactly why a proactive audit is worth the time it takes.
Where Transshipment Risk Actually Hides in a Supply Chain
Most importers who get caught in a transshipment investigation never intended to evade anything. The exposure usually sits one or two layers below where anyone is actually looking — in tier-two and tier-three component suppliers whose own sourcing has quietly shifted toward China as tariffs on direct China-origin goods have risen, and whose customer-facing documentation has not kept pace with that shift.
Bonded and free-trade-zone opslach in the countries named in the White House’s 40-plus list is another common blind spot. These zones offer legitimate advantages — lower labor costs, duty deferral, faster port access — but they also make it easy for a shipment to sit, be relabeled, and move on without anyone along the chain recording exactly what happened inside the facility. Freight forwarders who route cargo through these hubs purely for cost or transit-time reasons, without visibility into what processing actually occurs there, can unintentionally become part of a transshipment chain their own customer never asked for.
Invoicing structures create a third layer of risk. When a trading company or intermediary issues the commercial invoice from a third country, the paper trail can obscure the factory of origin entirely, even when the goods themselves never physically stopped anywhere questionable. And logistics partners themselves are a risk factor: a forwarder that cannot produce vessel manifests, bill-of-lading chains, and warehouse-in/warehouse-out records tying a shipment’s physical movement to its declared origin leaves the importer of record holding documentation gaps that CBP’s analytics are specifically built to detect.
A Practical Self-Audit Framework: Six Checks Before CBP Comes Knocking
A useful audit does not need to be a forensic investigation. It needs to answer, for every active supplier and lane, whether the paper trail actually matches the physical movement of goods. The table below outlines six checks worth running on a recurring basis, roughly quarterly for high-risk lanes and at least annually for everything else.
| Kontrôle | Wat te ferifiearjen | Why It Matters to CBP |
| Dokumintaasje fan oarsprong | Certificates of origin, mill certificates, and bills of materials trace back to a named facility, not a trading company. | CBP applies the substantial transformation test to the actual production facility, not the invoicing party. |
| Supplier sourcing changes | Ask suppliers directly whether raw material or component sourcing has shifted toward China in the last 12–18 months. | Rerouted component content is a primary driver of the current 40-country enforcement list. |
| Routing and transit history | Vessel manifests and transshipment ports match what is declared on the entry summary. | The Detective Border system flags routing histories that diverge from declared origin. |
| Warehouse dwell time | Check how long goods sit in third-country bonded warehouses and what processing, if any, occurs there. | Extended dwell time paired with minor processing is a recognized transshipment pattern. |
| Value and classification consistency | HTS codes and declared values are consistent across shipments of the same product from the same supplier. | Sudden shifts in classification or value are a standard AI anomaly-detection trigger. |
| Forwarder and broker records | Your logistics partners can produce complete, matching documentation on request within days, not weeks. | A slow or incomplete response to a CBP Form 28 is itself treated as a risk signal. |
The first two checks are the ones importers most often skip, largely because they require asking suppliers uncomfortable questions rather than reviewing internal paperwork. But since the current enforcement wave is explicitly targeting rerouted Chinese component content, a supplier’s sourcing shift is frequently the actual root cause of a transshipment finding, even when the importer’s own documentation was filed in good faith.
What CBP’s AI Enforcement Tools Are Actually Trained to Flag
CBP has been candid that its enforcement is now driven as much by data analytics as by physical inspection. The Detective Border platform continuously ingests global trade data and compares declared origins, routing histories, and component content against expected patterns for a given product category and trade lane. Understanding roughly what triggers a flag helps prioritize which parts of an audit deserve attention first.
| Sinjaal Kategory | Example Pattern That Gets Flagged |
| Routing anomaly | Cargo transits a bonded warehouse in a listed country with no clear commercial reason for the stop. |
| Classification drift | The same product suddenly enters under a different HTS code once tariffs on the prior code increase. |
| Value inconsistency | Declared unit value drops sharply for a shipment from a new intermediary without a matching cost explanation. |
| Dokumintaasje-oerienkomst | Certificate of origin lists a facility whose known production capacity cannot plausibly support the shipped volume. |
| Network clustering | Multiple unrelated importers share the same third-country intermediary, freight forwarder, or bonded facility. |
None of these signals alone proves wrongdoing, and CBP has said explicitly that being located in one of the 40-plus flagged countries does not imply guilt — it simply means origin claims from that jurisdiction will draw closer scrutiny. But an importer whose shipments repeatedly trip several of these signals at once is statistically far more likely to receive a Form 28 request, a site visit, or a referral to the Trade Fraud Task Force.
Penalty Exposure If CBP Finds the Problem First
The cost of a self-audit is measured in staff hours. The cost of CBP finding the same gap on its own is measured very differently.
| Soart oertreding | Primêre juridyske basis | Typysk gefolch |
| Negligent misdeclaration of origin | 19 U.S.C. § 1592 (negligence) | Penalty up to the loss of revenue, plus back duties and interest. |
| Grutte sleauwichheid | 19 U.S.C. § 1592 (gross negligence) | Penalty up to four times the loss of revenue. |
| Fraud / knowing transshipment | 19 U.S.C. § 1592 (fraud); criminal referral possible | Penalty up to the full domestic value of the merchandise; potential criminal exposure. |
| Whistleblower-triggered claim | False Claims Act | Treble damages plus per-violation civil penalties; whistleblower may recover a share of proceeds. |
| Confirmed transshipment tariff evasion | 2026 executive order framework | CBP has indicated mitigation or remission will not be available on these penalties. |
It is also worth noting that these signals compound rather than operate in isolation. A single classification change after a tariff adjustment is common and usually explainable; the same change paired with a new third-country intermediary and a warehouse stop that was not part of the prior routing is the kind of cluster that moves a shipment from routine review to active investigation. Importers who understand this compounding effect can prioritize fixing the combination of signals rather than chasing every individual data point in isolation.
That last row deserves particular attention. Under the standard Section 1592 framework, importers who self-disclose an error or negotiate in good faith have historically had access to penalty mitigation. The current administration’s transshipment-specific enforcement track appears designed to close that door for confirmed transshipment cases, which is precisely why catching the issue during your own audit — before it becomes a confirmed CBP finding — remains the version of this process with the most room to fix things quietly.
Building a Documentation File That Actually Holds Up
An audit is only as good as the paper trail it produces. When CBP does ask questions, the importers who resolve them quickly are the ones who can hand over a complete file within days rather than scrambling to reconstruct one from scratch.
At minimum, that file should tie together a signed certificate of origin from the actual producing facility, a bill of materials showing where major components were sourced, production records or factory audit reports supporting the substantial transformation claim, and a complete transportation chain from factory door to U.S. port of entry — including every bonded warehouse or transit stop along the way. Where a third-country facility performs any processing, it is worth documenting exactly what that processing involves, since “minor processing” is one of the specific tactics named in CBP’s own transshipment guidance.
Keeping this file current is as important as building it in the first place. Supplier sourcing shifts quietly over time, and a certificate of origin issued eighteen months ago may no longer reflect where a component is actually made today. Building a refresh cycle into supplier contracts — even a simple annual attestation — closes one of the more common gaps CBP’s investigators encounter.
How Topway Shipping Fits Into a Transshipment Risk Audit
A large share of transshipment exposure originates in the logistics layer rather than the factory floor, which is exactly why the freight forwarder you work with matters to this audit. Since 2010, Topway Shipping, headquartered in Shenzhen, has built its business around end-to-end China–U.S. logistics: first-leg transportation out of the origin factory, overseas warehousing, customs clearance, and last-mile delivery, backed by a founding team with more than 15 years of experience in international logistics and customs work.
That end-to-end structure is useful for exactly the kind of documentation gaps described above. Because Topway manages the shipment from factory pickup through to U.S. delivery rather than handing it off between disconnected intermediaries, clients get a continuous chain of custody — vessel and warehouse records that can actually be matched against declared origin, rather than assembled after the fact from three or four unrelated parties. Topway also offers flexible full-container-load and less-than-container-load ocean freight direct from China to major ports worldwide, which gives importers a straightforward way to avoid unnecessary transit through third-country hubs when a direct routing is available and makes more sense for the shipment.
For importers running the six-check audit outlined above, a forwarder that can produce complete routing and warehouse-dwell documentation on short notice turns two of the hardest checks — routing history and forwarder record completeness — into a quick phone call rather than an open-ended investigation.
Common Mistakes Importers Make When Running This Audit Themselves
The most common mistake is treating the audit as a one-time paperwork review rather than an ongoing conversation with suppliers and logistics partners. A certificate of origin collected during onboarding is a snapshot, not a guarantee, and factories under margin pressure from tariffs on their own inputs have every incentive to quietly source cheaper components from wherever they can find them, whether or not that shows up in the next invoice.
A second mistake is auditing the importer’s own paperwork while leaving the freight forwarder’s records out of scope. CBP does not stop its inquiry at the importer of record; it traces the full movement of goods, and a forwarder that cannot reconstruct a shipment’s port history and warehouse dwell time becomes the weak link in an otherwise clean file. Importers who only ask “is my invoice correct” and never ask “can my forwarder prove where this actually went” tend to be the ones surprised by a Form 28 request months later.
A third, quieter mistake is assuming that low-value or low-tariff product lines are safe to skip. Enforcement resources are finite, but the AI-driven screening tools run across every entry, not just the high-dollar ones, and a pattern that spans dozens of small shipments can trigger the same network-clustering flag as a single large one. A useful audit covers the full portfolio, weighted by risk rather than by dollar value alone.
Konklúzje
The current wave of CBP enforcement is not a passing headline. It is backed by billions of dollars in new staffing, a dedicated cross-agency task force, an AI analytics platform built specifically to catch routing and origin inconsistencies, and a legal framework that appears designed to close off the mitigation options importers have relied on in the past. Against that backdrop, the choice is not really between auditing your supply chain or not — it is between finding a documentation gap yourself, on your own schedule, or having CBP find it for you, on theirs. Running the six checks outlined here, keeping supplier attestations current, and working with logistics partners who can produce a complete, defensible chain of custody are the practical steps that separate importers who sail through a Form 28 request from those who end up explaining themselves to the Trade Fraud Task Force.
FAQs
Q: Does being located in one of the 40-plus flagged countries automatically mean a shipment will be penalized?
A: No. CBP has stated that appearing on the list does not imply guilt; it means origin claims from that jurisdiction will receive closer scrutiny, particularly when other risk signals are also present.
Q: How often should an importer re-run this kind of audit?
A: Quarterly for high-risk lanes involving components with a history of tariff exposure, and at least annually for the rest of the supply chain, since supplier sourcing can shift well before documentation catches up.
Q: Can self-disclosing a transshipment issue still reduce penalties?
A: Under the standard Section 1592 framework, self-disclosure has historically helped, but CBP has signaled that mitigation and remission will not be extended to confirmed transshipment penalties under the current enforcement track, which makes catching the issue before it becomes a confirmed finding especially valuable.
Q: What is the fastest way to close a documentation gap uncovered during an audit?
A: Start with the supplier and the logistics chain simultaneously: request an updated certificate of origin and sourcing attestation from the supplier, and ask your freight forwarder to produce the full routing and warehouse-dwell record for the lane in question.
Q: Does routing cargo through a bonded warehouse always create transshipment risk?
A: Not on its own. Bonded and free-trade-zone warehousing is a legitimate part of many supply chains; the risk arises when dwell time, relabeling, or minor processing at that facility is not documented and cannot be tied back to the shipment’s declared origin.
Q: Who ultimately bears the penalty risk if a supplier misrepresents origin without the importer’s knowledge?
A: In most cases, the importer of record carries the legal responsibility for the accuracy of the entry, which is why supplier attestations and independent verification matter even when the importer acted entirely in good faith.
