The US government lost an estimated USD 107 billion to tariff evasion in 2025, according to the Dow Jones Risk Journal. Goldman Sachs economists calculated that evasion of Section 301 tariffs alone may have caused duty collection losses of USD 110 to 130 billion since 2018. Those numbers are why the enforcement response has been unlike anything the trade compliance world has seen in a generation. In the first six months of fiscal year 2025, CBP issued 1,400 trade enforcement penalties in the first half of fiscal year 2025, cited by Holland and Knight from CBP’s own website, and reported via CBP official enforcement records, on pace to exceed every prior year’s total. CBP recovered USD 192.77 million by June 30, already surpassing the entire FY2024 total of USD 117.7 million. The DOJ designated tariff evasion a high-impact enforcement priority in May 2025. The Trade Fraud Task Force launched in August 2025 as a cross-agency operation with DHS. The False Claims Act is now a primary enforcement tool alongside Section 1592, and your competitor may be the one who reports you. None of this is news to the bad actors deliberately evading tariffs under US tariff evasion enforcement 2026. It is a serious and growing risk for the legitimate importer who has never evaded anything, but whose documentation is thin, whose HTS classifications have not been reviewed since 2022, and whose supplier in China has been quietly transshipping through a third country. This guide explains what US tariff evasion enforcement 2026 actually looks like, what the legitimate importer’s specific exposure is, and the four actions that reduce your risk before CBP’s AI finds you first.
The 2026 enforcement picture in five numbers:
- USD 107 billion estimated lost to tariff evasion in 2025 (Dow Jones Risk Journal)
- 1,400 trade enforcement penalties issued by CBP in the first half of fiscal year 2025 alone
- USD 192.77 million recovered by CBP through June 2025, already exceeding all of FY2024
- 160% year-on-year surge in CBP evasion complaints between March and May 2025
- 5,000 new customs officers being hired under the One Big Beautiful Bill Act
US Tariff Evasion Enforcement 2026: Why Legitimate Importers Are Now at Risk
Most importers who find this guide on US tariff evasion enforcement 2026 have never filed a false customs declaration. They have never deliberately understated the value of imported goods, fabricated a country of origin, or routed Chinese goods through a third country to avoid Section 301 tariffs. They are not the target of the DOJ’s enforcement programme.
But here is the problem. The same enforcement infrastructure that CBP built to catch deliberate evaders is now being used to catch negligent importers. The same False Claims Act that has produced multi-million-dollar settlements against fraudsters can be triggered by a former employee or a competitor with information about your import programme. The same AI-driven analytics system that identifies transshipment schemes also flags HTS classification anomalies that look suspicious even when they are the result of genuine misclassification rather than fraud. And the same Importer of Record who bears legal liability for every customs declaration under the Customs Modernization Act’s reasonable care standard is accountable for their supplier’s actions as well as their own.
The legitimate importer’s risk under US tariff evasion enforcement 2026 is not that they will be treated as a deliberate fraudster. The risk is that the enforcement environment has become so broad, so well-resourced, and so data-driven that the documentation gaps, classification errors, and supply chain opacity that were manageable compliance issues two years ago are now active enforcement exposure.
US Tariff Evasion Enforcement 2026: The Scale of CBP’s New Capability
The US tariff evasion enforcement 2026 apparatus that will process your next import entry looks nothing like it did three years ago. Four structural changes have made CBP’s enforcement capability materially stronger in 2026 than at any prior point:
- Advanced Trade Analytics Program: CBP’s AI and machine learning system aggregates and analyses vast amounts of historical and current trade data to identify patterns, anomalies, and trends in the trade environment that suggest evasion. This system compares your current classifications, valuations, and declared origins against your own historical pattern, industry benchmarks, and known evasion schemes. A classification change that reduces your duty liability without a corresponding change in product description will produce an algorithmic flag. A sudden increase in imports from Vietnam for a product category where your supplier has historically been in China will produce an algorithmic flag. You do not need to be doing anything wrong for the flag to appear. You need to have an explanation ready when it does
- Trade Fraud Task Force: Launched August 2025, the TFTF operates as a cross-agency operation involving DOJ’s civil and criminal divisions, CBP, DHS, and other federal agencies. Its mandate is to synchronise civil, criminal, and administrative enforcement against tariff evasion. Before the TFTF, a CBP administrative penalty under Section 1592 was the typical outcome of a compliance failure. Now the same set of facts can simultaneously produce a CBP administrative penalty, a DOJ False Claims Act investigation, and a criminal referral, three parallel proceedings with three separate legal teams each with subpoena power
- CBP funding surge: The One Big Beautiful Bill Act, signed into law on July 4, 2025 and confirmed by KPMG customs enforcement analysis, allocated USD 4.1 billion in additional CBP funding. Up to 5,000 new customs officers are being hired and trained. New AI, machine learning, and other surveillance technologies are being procured. The agency that reviewed your import entries last year with a workforce of a certain size will review your entries next year with materially more capacity and more sophisticated tools
- E-allegations and whistleblower programme: CBP’s online e-allegations portal allows any person, including competitors, former employees, and supply chain partners, to report suspected tariff evasion. CBP has issued 1,400 trade enforcement penalties in the first half of 2025 and is on pace to issue more penalties this year than it did in each of the last five years. The DOJ has expanded its Corporate Whistleblower Awards Pilot Programme specifically to cover customs and trade fraud, meaning the person who reports your import programme can receive up to 30% of any funds recovered
US Tariff Evasion Enforcement 2026: The Five Schemes CBP Is Targeting
Every legitimate importer needs to understand these five schemes, not to commit them, but because each produces a pattern CBP’s analytics system flags. Some of those patterns appear even when you have done nothing wrong. Documentation is what separates the cleared from the investigated.
Scheme 1: HTS Misclassification
Declaring goods under an HTS code with a lower duty rate than the correct code. Deliberate fraud or genuine error: CBP’s analytics does not distinguish until it investigates. Every importer who has not reviewed classifications since 2022, when Section 301 rates changed substantially, carries misclassification exposure. Real cost: a patio furniture company paid USD 4.9 million in July 2025 for misclassifying extruded aluminium from China.
Scheme 2: Undervaluation
Declaring a customs value lower than the actual transaction value to reduce ad valorem duty liability. Double-invoicing is the primary form: one invoice to CBP at a lower value, a second reflecting the actual commercial price. The Barco Uniforms DOJ case filed in April 2025 used exactly this scheme. The importer paid the real price to the manufacturer and submitted false invoices to CBP.
Scheme 3: False Country of Origin
Declaring Chinese-origin goods as Vietnamese, Malaysian, or Indian to avoid Section 301 tariffs. Evolutions Flooring paid USD 8.1 million in March 2025 after a competitor whistleblower reported origin misrepresentation on Chinese wood flooring. The goods were routed through a third country with processing so minimal it did not constitute a substantial transformation under US customs law.
Scheme 4: Transshipment
Chinese-origin goods routed through Malaysia, Vietnam, Thailand, or Cambodia without sufficient transformation to change origin, then declared as originating in the transit country. CBP’s Advanced Trade Analytics Program is specifically calibrated for this. The algorithm flags sourcing shifts from China to Southeast Asia immediately following a tariff increase, implausible export volumes from transit countries, and processing times too short for genuine transformation. Ceratizit USA settled for USD 54 million in December 2025 on exactly this scheme.
Scheme 5: Double-Dipping on Exemptions
Claiming two exemptions that cannot simultaneously apply to the same goods. CBP identified an importer of iron, steel, and aluminium who claimed both Section 232 and Reciprocal Tariff exemptions on the same shipments, attempting to deprive the government of USD 100 million. This is a specific and active enforcement target in 2026.
US Tariff Evasion Enforcement 2026: The Penalty Structure Every Importer Must Know
The financial consequences of a tariff evasion finding under US tariff evasion enforcement 2026 operate on three levels simultaneously, each with different legal authority and different financial exposure:
Level 1: Section 1592 Civil Penalties (CBP Administrative)
Three culpability levels. Three very different financial outcomes. The Trump administration has moved to limit penalty mitigation, making these headline figures more likely to stick than in prior administrations.
| Culpability Level | What It Means | Maximum Penalty | Example on USD 500K Underpaid |
|---|---|---|---|
| Negligence | Honest mistake, failed reasonable care | 2x unpaid duties or domestic value, whichever is less | USD 1 million |
| Gross Negligence | Serious disregard for legal requirements | 4x unpaid duties or domestic value, whichever is less | USD 2 million |
| Fraud | Deliberate deception of CBP | Full domestic value of merchandise | Can exceed USD 10 million+ on large programmes |
Level 2: False Claims Act (DOJ Civil)
The False Claims Act is now a primary enforcement tool alongside Section 1592. FCA liability includes treble damages, three times the duties evaded, plus civil penalties of up to USD 28,619 per false claim. The FCA can be triggered by private whistleblowers including competitors. The Evolutions Flooring case was filed by a competitor. Global Office Furniture by a former employee. Whistleblowers receive up to 30% of recovered funds, creating powerful financial incentives for anyone with knowledge of your import practices to report them.
Level 3: Criminal Prosecution
For cases involving deliberate fraud, DOJ can pursue criminal prosecution under 18 USC Section 541 (importation of goods at a lower value than actual value) and 18 USC Section 542 (entry of goods by means of false statements). The former COO of a plastic resin distributor pleaded guilty in December 2025 to conspiracy to smuggle goods into the United States after instructing subordinates to misrepresent country of origin on CBP documents to avoid Section 301 duties. FCA and criminal investigations can run simultaneously with CBP administrative proceedings, three parallel legal processes with overlapping but distinct liability exposure.
The IOR’s Specific Liability Under US Tariff Evasion Enforcement 2026
The Customs Modernization Act of 1993 requires the what an Importer of Record is responsible for includes exercising reasonable care when completing the entry of goods, to allow CBP to properly assess duties and ensure compliance with US laws including correct classification, valuation, and origin. The reasonable care standard creates legal accountability for the IOR that extends beyond their own decisions to include their supplier’s representations.
Three specific IOR liability scenarios that legitimate importers face in 2026:
- Supplier-driven evasion that the IOR did not know about: If your Chinese supplier has been transshipping goods through Vietnam and providing you with Vietnamese certificates of origin that you have declared in good faith, you are the IOR on the customs entry. CBP’s investigation will start with you. The question is whether you exercised reasonable care in verifying your supplier’s origin claims. If you did not conduct origin audits, request supply chain documentation, or verify that the Vietnamese processing was sufficient to constitute a substantial transformation, you may not meet the reasonable care standard regardless of your intent
- Classification errors that were not reviewed as tariffs changed: Many importers classified their goods correctly in 2020 and have not reviewed those classifications since. As Section 301, Section 232, and Section 122 tariffs applied new rates to different product categories, the commercially correct classification for duty planning purposes may have diverged from the legally correct classification. An HTS code that was accurate before 2025 may now be drawing higher or lower duties than the correct code. CBP’s analytics will flag the discrepancy regardless of when the error originated
- Whistleblower exposure from within your supply chain: Former employees, competitors, freight forwarders, and customs brokers all have access to your import data and all have financial incentives to report anomalies to CBP’s e-allegations portal. The expanded DOJ Corporate Whistleblower Programme specifically covers trade and customs fraud. An import programme that would have been reviewed only in the context of a CBP audit two years ago can now be the subject of a qui tam FCA lawsuit filed by someone with no connection to your organisation other than knowledge of your import practices
US Tariff Evasion Enforcement 2026: The Real Cases and What They Cost
These are not hypothetical scenarios. They are verified DOJ and CBP enforcement actions from the past twelve months:
- Evolutions Flooring: USD 8.1 million (March 2025). Misrepresented country of origin of Chinese multilayered wood flooring to avoid antidumping, countervailing, and Section 301 duties. Filed by a competitor whistleblower who received USD 1.2 million
- Allied Stone Inc: USD 12.4 million (August 2025). Evaded antidumping and countervailing duties on quartz surface products from China. The company president was personally named in the settlement. Former employee whistleblower received USD 2.17 million
- Plastic resin importer: USD 6.8 million (July 2025). Failed to declare correct country of origin and value for imports from China, resulting in underpayment of duties. Voluntary self-disclosure was part of the resolution
- Global Office Furniture: Pending. DOJ intervened in a qui tam suit alleging conspiracy with a Chinese manufacturer to underpay customs duties on office chairs using double-invoicing. The complaint also alleges the defendants attempted to destroy evidence of the fraud once they learned of the investigation
- Ceratizit USA: USD 54 million (December 2025). Settled allegations of transshipping Chinese-origin tungsten carbide cutting tools through third countries to avoid Section 301 tariffs. One of the largest customs fraud settlements in recent history and a direct signal of CBP’s AI-assisted detection capability on transshipment patterns
- Iron, steel and aluminium importer: USD 100 million scheme identified. Claimed both Section 232 and Reciprocal Tariff exemptions simultaneously on the same goods to deprive the government of USD 100 million. Named by CBP as a specific evasion scheme type being targeted in 2026
US Tariff Evasion Enforcement 2026: Prior Disclosure Dramatically Reduces Your Exposure
The most commercially underused tool in US customs compliance is voluntary prior disclosure. Under CBP’s prior disclosure programme, an importer that identifies a customs violation and voluntarily discloses it to CBP before a formal investigation begins receives dramatically reduced penalties:
- For negligence and gross negligence violations: penalty is reduced to the interest on the amount of duties owed, rather than two or four times the duties
- For fraud violations: penalty is reduced to 100% of the lawful duties, taxes, and fees owed, or 10% of the dutiable value, rather than the full domestic value of the merchandise
The difference between a prior disclosure outcome and a full enforcement outcome can be the difference between a manageable duty payment and a penalty that threatens the viability of the business. The key is timing: prior disclosure must be made before CBP has commenced a formal investigation. Once CBP has opened an investigation, prior disclosure is no longer available. For importers who conduct internal audits and discover classification errors, valuation discrepancies, or origin issues, the prior disclosure decision is the most commercially significant compliance choice they face. A group of importers paid USD 6.8 million in July 2025 to resolve False Claims Act liability relating to a voluntary self-disclosure of unpaid customs duties, a fraction of what a full enforcement proceeding could have produced.
US Tariff Evasion Enforcement 2026: Four Actions Every Importer Must Take Now
- Conduct a classification audit of your entire active HTS code portfolio. Pull every 10-digit HTS code on which you have filed entries in the last three years. For each code, confirm the classification is correct against the current tariff schedule. Specifically check whether any classification decisions made before 2022 still hold under the current tariff structure, whether any codes carry Section 301 or Section 232 rates that have changed, and whether any products have been reclassified in ways that reduce duty liability without corresponding changes to product description. An incorrect but innocent classification discovered in an internal audit is a prior disclosure candidate. The same classification discovered by CBP’s Advanced Trade Analytics Program is a penalty candidate. Our Global Trade Compliance team conducts HTS classification audits across active import portfolios and identifies prior disclosure candidates before CBP’s analytics do
- Audit your country of origin claims at tier-two supplier level. Request supply chain documentation from every tier-one supplier showing where each component originates and where sufficient transformation occurs. For suppliers in Vietnam, Malaysia, Thailand, Indonesia, and Cambodia who were not your suppliers before 2018, verify that the processing they perform constitutes a substantial transformation under US customs law. If you cannot produce origin documentation that would satisfy CBP’s reasonable care standard, you have exposure. If your supplier cannot produce it, you have exposure and a procurement decision to make before CBP’s analytics flag the pattern
- Review your supplier contracts for customs compliance representations. Every supply agreement should contain representations from the supplier about the accuracy of country of origin declarations, the completeness of HTS classification information, and the supplier’s compliance with applicable US customs law. If your current contracts do not contain these representations, you have no contractual protection when a supplier’s evasion scheme becomes your CBP problem. Adding customs compliance representations to new and renewed contracts does not eliminate your reasonable care obligation but it documents the steps you took to meet it
- Establish a compliance escalation procedure as your fourth US tariff evasion enforcement 2026 response for anomalies in your import data. CBP’s Advanced Trade Analytics Program will flag patterns in your import data. You should be finding those patterns first. Under US tariff evasion enforcement 2026, a basic monitoring programme comparing your HTS classifications and valuations against historical patterns, identifies outliers, and routes them for review before the next entry is filed costs far less than the legal fees for a Section 1592 response. Any anomaly that cannot be explained by a documented business reason is a prior disclosure candidate. Our IOR services include ongoing compliance monitoring as part of the import management function, ensuring that classification anomalies are identified and addressed within the import process rather than after a CBP flag
How Carra Globe Protects Importers in the 2026 Enforcement Environment
Carra Globe provides IOR services and Global Trade Compliance with the reasonable care standard at the core of every customs entry we file. Our trade compliance team manages HTS classification with documented classification opinions for each product category, country of origin verification at tier-one and tier-two supplier level, customs valuation review against transaction value requirements, and ongoing monitoring of classification and origin patterns against CBP enforcement priorities. For businesses importing from China, Vietnam, India, Malaysia, and other markets where CBP’s analytics are actively targeting transshipment patterns, our origin verification protocols provide the documented audit trail that demonstrates reasonable care if CBP investigates. Our Delivered Duty Paid service incorporates duty liability into full landed cost calculations using correctly classified HTS codes and verified origin determinations, so the duty cost reflected in your procurement decision is the legally correct one.

Frequently Asked Questions: US Tariff Evasion Enforcement 2026
Can I be penalised under US tariff evasion enforcement 2026 for my supplier’s evasion?
Yes, and this is the part most importers do not expect. The law does not require intent. If your supplier gave you false origin documentation and you declared it to CBP without verification, CBP asks one question: did you exercise reasonable care? If you never audited your supplier’s origin claims, never verified that transit country processing was sufficient, and cannot produce documentation showing you tried. That is a failure of reasonable care. Your ignorance of the fraud is not a defence if the steps to detect it were available to you.
What is the difference between negligence and fraud in a US tariff evasion enforcement 2026 case?
Three levels, three very different outcomes. Negligence (you made a mistake without intent) means penalties up to twice the duties underpaid. Gross negligence (you seriously disregarded the rules) means up to four times the duties. Fraud (you deliberately deceived CBP) means penalties up to the full domestic value of the goods, which can dwarf the duty amount many times over. CBP decides which level applies first. You can challenge that through a petition, but the burden of proof shifts to you.
What is prior disclosure and how does it reduce exposure in US tariff evasion enforcement 2026?
It is the most underused tool in US customs compliance. If you find a violation in your own records and report it to CBP before they open a formal investigation, your penalty drops dramatically. For negligence and gross negligence, you pay interest on unpaid duties only, not two or four times the amount. For fraud, you pay 100% of the duties owed instead of the full domestic merchandise value. The catch: the window closes the moment CBP opens a formal investigation. If your internal audit finds something, the prior disclosure decision needs to happen the same day, with legal counsel.
Can a competitor report my import practices under US tariff evasion enforcement 2026?
Yes, and the financial incentive is significant. CBP’s e-allegations portal is open to anyone. The Evolutions Flooring settlement of USD 8.1 million was initiated by a competitor who received USD 1.2 million of the proceeds. The DOJ’s Whistleblower Programme pays out up to 30% of recovered funds to anyone who reports customs fraud, including competitors and former employees. If a company in your space suspects your import costs are lower than theirs because of how goods are classified or declared, they have both the motive and the mechanism to act on it.
What does CBP target in US tariff evasion enforcement 2026 using its analytics programme?
The system looks for things that do not add up. Your sourcing suddenly shifts from China to Vietnam right after a Section 301 rate increase. Your HTS classification changes in a way that lowers your duty bill without any change to the product. Your declared supplier country is exporting volumes that are implausible given its manufacturing capacity. You are claiming two exemptions that cannot logically apply to the same shipment. None of these automatically mean you did something wrong. All of them will generate a flag and require an explanation.
How does reasonable care work for the IOR under US tariff evasion enforcement 2026?
It means doing the work, not just trusting what your supplier sends you. Documented classification opinions for each product. Origin verification through actual supply chain records, not just supplier certificates. Transaction values cross-checked against related-party pricing rules where relevant. An internal monitoring process that catches anomalies before CBP’s AI does. The difference between an importer who exercised reasonable care and one who did not is almost always a paper trail. If you can show CBP what you did to verify accuracy, your legal position is fundamentally stronger than if you cannot.
