The White House has accused more than 40 nations, including some of its closest partners, of helping Chinese goods evade US tariffs by exploiting differences in levies imposed on third countries. 

A new 25-page report titled ‘The Great Transshipment Scam’, released by the White House on Thursday, names Canada, Mexico, Japan, South Korea, India, Israel, Taiwan, and the EU among those allegedly involved in the practice. 

The document claims the “scam” involves sending Chinese-made goods through another country, where they are lightly processed, repackaged, or relabeled before being shipped to the US under a new declared origin. 

Washington says the practice took off after President Donald Trump imposed sweeping tariffs on Chinese products in 2018. Since returning to office, Trump has expanded levies to much of the world, creating wide differences in tariff rates between trading partners. Last month, he also imposed new tariffs on imports from 60 countries over alleged failures to combat forced labor, drawing protests from several major US partners. The White House acknowledged that such gaps may themselves have increase incentives for rerouting. 

The report estimates that the practice costs the US Treasury tens of billions of dollars annually. Under one central model-based scenario, it puts lost federal revenue at $19 billion to $26 billion and claims around 450,000 American jobs could be displaced. 
Washington said it now plans to step up enforcement using an AI-based customs system dubbed ‘Detective Border’, designed to flag suspicious shipping routes, origin claims, and ownership links. The report warns that violators could face additional tariffs, sanctions, or exclusion from the US market.

China has repeatedly condemned Trump’s tariff regime, accusing Washington of protectionism and economic coercion and arguing that its trade and technology restrictions disrupt global commerce.

Earlier this month, the Chinese Commerce Ministry announced tighter export controls on drones and related technologies and retaliatory measures against several American entities, warning of further countermeasures if Washington introduces new restrictions.
