Tariff fraud schemes: Fraudology update on new VAMP changes and tariff dodging schemes
Today I am talking about tariff fraud schemes and what happens when regulatory changes and economic pressure start reshaping fraud patterns in ways a lot of teams do not see coming quickly enough. Because that is really the issue here. Fraud does not stay neatly inside policy announcements or trade headlines. I see it show up in merchant behavior, cross-border order flows, chargebacks, fraud models, and the very messy gray area between legitimate adaptation and obvious abuse.
In this episode of Fraudology, I share important updates on Visa’s Acquirer Monitoring Program, or VAMP, and then connect those changes to the ripple effects recent tariffs are having across ecommerce fraud. I walk through delayed implementation timelines, how acquirer fees passed to merchants are likely to work, how Ethoca, CDRN, and RDR alerts may affect fraud ratio management under VAMP, and why post-authorization fraud system impact is becoming a bigger concern.
I also get into tariff dodging ecommerce fraud, straw merchant fraud, customs delay chargebacks, freight forwarding fraud risk, and the ways cross-border fraud schemes are evolving as businesses and fraudsters respond to the pressure. And this matters. Because tariff fraud schemes are not just about bad actors finding loopholes. They are also about those of us on fraud teams trying to separate real risk from strange but explainable behavior in a very unstable operating environment.
Here is what that fraud lens means in practice:
- Tariff fraud schemes often show up as operational anomalies before they are clearly labeled as fraud
- VAMP updates for merchants can change how I think, and how you may need to think, about alerts, ratios, and post-authorization controls
- Tariff dodging ecommerce fraud creates new pressure around cross-border ecommerce risk management
- Suspicious order behavior during tariffs may reflect either fraud, legitimate market response, or some messy mix of both
What you’ll hear in this episode:
- What the latest VAMP updates for merchants mean for implementation timing, fees, and fraud ratio management under VAMP
- Why Ethoca alert impact on VAMP, CDRN alert fraud ratio reduction, and RDR alert fraud prevention matter so much
- How tariff fraud schemes are showing up through straw merchant fraud, customs delay chargebacks, and freight forwarding fraud risk
- Why Canadian account fraud abuse and cross-border fraud schemes are becoming more relevant under tariff pressure
- How stockpiling triggers fraud models and complicates merchant fraud strategy during tariff changes
You should listen to this episode if you:
- Work in fraud, payments, risk, or ecommerce operations and need to understand tariff fraud schemes
- Want practical insight into VAMP updates for merchants, Visa enumeration program changes, and regulatory change fraud impacts
- Need clearer context on tariff dodging ecommerce fraud, straw merchant fraud, and suspicious order behavior during tariffs
- Are reviewing customs delay chargebacks, freight forwarding fraud risk, or cross-border ecommerce risk management
- Want to improve merchant fraud strategy during tariff changes without overreacting to every anomaly

Episode notes & key takeaways
VAMP updates are changing the fraud ratio conversation for merchants
Let’s break this down. A lot of teams were already trying to make sense of VAMP, and then the details shifted again. That is part of why this update matters. I explain that implementation has been delayed until October 1st, with fines not taking effect until January 2024, and that acquirers will likely pass VAMP fees onto merchants who exceed certain fraud thresholds.
That alone would be enough to keep merchants busy. But the more important part may be the expected treatment of alerts. If Visa announces that Ethoca, CDRN, and RDR alerts will count toward reducing merchants’ fraud ratios, that changes the practical strategy. A lot.
Why does that matter? Because fraud ratio management under VAMP is not just about total fraud volume. It is about what counts, when it counts, and how merchants can use available dispute and alert channels to reduce pressure before fines or escalations hit. That is where things get operational very quickly.
- VAMP updates for merchants affect timing, enforcement pressure, and fraud ratio strategy
- Acquirer fees passed to merchants may become a real cost issue for programs already under strain
- Ethoca alert impact on VAMP could materially change ratio management approaches
- CDRN alert fraud ratio reduction and RDR alert fraud prevention may become more strategically important than teams expected
Post-authorization systems may feel the pressure from VAMP and enumeration changes
I also point out something a lot of teams need to pay closer attention to: post-authorization fraud system impact. And yes, that is a problem. Because when new monitoring requirements intersect with alert treatment and Visa enumeration program changes, teams relying on post-auth workflows may find themselves absorbing pressure they did not fully anticipate.
At first glance, a lot of VAMP conversation can sound like acquirer policy and merchant compliance. But when you look closer, it has real consequences for how fraud is detected, escalated, and counted after authorization. That affects tooling, workflows, and internal ownership.
This is exactly the kind of regulatory change fraud impact that creates downstream confusion if teams are not aligned early. Not because the rules are impossible to understand. Because they interact with existing systems in ways that are easy to underestimate until the costs show up.
- Post-authorization fraud system impact may increase as merchants adapt to VAMP requirements
- Visa enumeration program changes can create added stress on already complex fraud workflows
- Regulatory change fraud impacts often show up in operational systems before policy teams fully catch up
- Merchant fraud strategy during tariff changes and VAMP shifts will need tighter coordination across functions
Tariff fraud schemes are creating strange order behavior and new abuse patterns
The second half of the episode gets into the ripple effects of tariffs, and this is where things get interesting. I share conversations with retail executives that point to a mix of customs delays, increased chargebacks, stockpiling behavior, and new evasion tactics that are forcing fraud teams to rethink what suspicious really looks like.
This is important because tariff fraud schemes do not always present as classic fraud right away. Sometimes they show up as volume spikes, odd shipping behavior, unusual cross-border activity, or orders that trip fraud models for reasons that are partially legitimate. That is the tension.
Stockpiling triggers fraud models because behavior changes fast under economic pressure. Large purchases, unusual category mixes, or repeat buying can look like abuse when they may actually reflect customers or businesses responding to cost increases. And that means fraud teams need more context, not just more alerts.
- Tariff fraud schemes often distort normal order patterns in ways fraud models may misread
- Ecommerce tariff risk signals can look similar to both legitimate stockpiling and coordinated abuse
- Suspicious order behavior during tariffs requires more contextual review than usual
- Merchant fraud strategy during tariff changes should account for market disruption, not just static rules
Straw merchants, freight forwarding, and Canadian account abuse show how fast fraud adapts
I also highlight more direct abuse patterns, including straw merchant fraud, freight forwarding fraud risk, and the use of Canadian accounts in cross-border fraud schemes. And this is where the problem becomes a lot less ambiguous.
Here’s what is actually happening. When tariffs create cost pressure or operational friction, fraudsters look for structures that help them dodge fees, reroute goods, or exploit cross-border gaps. Straw merchants can be used to avoid scrutiny or pass costs around. Freight forwarding services can create new blind spots. Canadian account fraud abuse can help support schemes that move across borders with less immediate friction.
We have seen this playbook before. Not the exact tariff context, maybe. But the broader pattern is familiar. Economic changes create loopholes. Fraudsters move quickly. Teams downstream are left sorting out what is weird, what is abusive, and what is now the new normal.
- Straw merchant fraud can emerge when bad actors try to sidestep tariff-related costs or controls
- Freight forwarding fraud risk increases when shipping pathways become part of the abuse strategy
- Canadian account fraud abuse may support cross-border fraud schemes exploiting regional differences
- Cross-border ecommerce risk management gets more complicated when fraud adapts to trade friction
Fraud teams need more flexibility when market conditions change this fast
The broader lesson from this episode is that tariff fraud schemes are not just a fraud problem or a policy problem. They are an adaptation problem. We are being asked to evaluate behaviors that may be risky, rational, or both at the same time. That is not easy.
This is why rigid assumptions get dangerous during periods like this. If every anomaly is treated as fraud, good customers and legitimate merchants get caught in the mess. If every strange pattern is written off as market behavior, abuse slips through. The real work is in sorting signal from noise while the environment keeps moving.
And that is exactly why updates like this matter. They give teams a better chance to recalibrate before the losses and operational drag build up too far.
- Tariff fraud schemes require flexible fraud review, not one-size-fits-all assumptions
- Cross-border ecommerce risk management gets harder when fraud and market disruption overlap
- Regulatory change fraud impacts should be evaluated alongside real merchant and consumer behavior shifts
- Good fraud strategy during tariff changes depends on fast learning and strong internal coordination
The bigger theme in this episode is that fraud pressure does not just come from criminals. It also comes from policy changes, economic shifts, and the unintended consequences that ripple through payments and commerce when the rules move. My update on VAMP and tariff fraud schemes is useful because I connect those dots clearly. For fraud teams, that means staying close to both the fraud signals and the business context, especially when both are changing at the same time.
