The US government is deploying artificial intelligence to solve a problem that’s been vexing trade enforcers for years: figuring out whether a product labeled “Made in Vietnam” actually spent most of its life in a Chinese factory.
The Trump administration’s new AI system, dubbed the “detective border,” is designed to identify and intercept goods that are illegally rerouted through third countries to dodge US tariffs on Chinese products. A report from the White House Office of Trade and Manufacturing Policy, released on August 13, 2026, names more than 40 countries as participants in what amounts to a global game of tariff hide-and-seek.
The scale of the problem
The numbers explain why Washington decided to throw machine learning at this. According to estimates from AI supply chain firm Exiger, roughly $75 billion worth of goods may have been illegally transshipped between February 2025 and February 2026.
The resulting hit to the US Treasury: somewhere between $19 billion and $34 billion in lost tariff revenue.
The White House report identifies the usual suspects and some surprising ones. Mexico, Canada, the European Union, India, Japan, and South Korea all made the list of top enablers.
How the system actually works
The system pulls together multiple data streams to build a picture of whether a shipment is what it claims to be. It analyzes shipment data, routing histories, production capacities, ownership ties, and packaging patterns. It also incorporates X-ray imaging at ports to spot discrepancies between what’s declared on paper and what’s actually sitting in a container.
The core challenge is something trade lawyers call “substantial transformation.” Under US rules, a product’s country of origin changes if it undergoes meaningful processing in a different country. A Chinese steel coil that gets stamped into auto parts in Thailand genuinely becomes Thai-origin goods. But a Chinese steel coil that gets repacked in a Thai warehouse with new paperwork does not.
Why this keeps getting harder
During Trump’s first term, companies adopted what supply chain consultants call the “China+1” strategy: maintaining Chinese manufacturing while adding a secondary production base in countries like Vietnam, Thailand, or India. Some of that diversification was genuine. Some of it involved little more than a new shipping label and a modest assembly step designed to satisfy origin rules.
The strategy accelerated dramatically as tariff rates climbed higher in the current term. With duties on Chinese goods reaching levels that make direct import economically irrational for many product categories, the financial incentive to find creative workarounds has only grown.
Market fallout and what to watch
Companies that have built supply chains around tariff optimization are about to face a very different risk calculus. Increased scrutiny means higher compliance costs, more shipment delays, and the possibility of retroactive penalties for past transshipments that the AI flags as suspicious.
The sectors most exposed are predictable: technology, manufacturing, and consumer goods, the same industries that have been most aggressive about rerouting supply chains since tariffs first escalated.
