Amazon has a particularly interesting new cross-border experiment

Amazon is piloting a “test once” compliance model intended to make international expansion easier for sellers. The idea is that qualifying products tested for one marketplace can reuse those results elsewhere rather than repeatedly undergoing substantially similar compliance testing.
The initial pilot focuses on toys, with electronics and baby products expected to follow. Amazon says the approach could cut some seller compliance costs by as much as 60%.
This matters because one reason smaller sellers avoid international expansion isn’t necessarily demand. It’s operational friction:
testing + documentation + customs + tax + listings + fulfilment + regulatory requirements.
Amazon says only about 30% of its merchants currently sell in more than one country.
Seller implication: when evaluating international expansion, don’t ask only:
“Can we sell this product in the U.S.?”
Build a Cross-Border Readiness Sheet containing regulatory requirements, testing, landed cost, duties, fulfilment, returns, marketplace fees and expected contribution margin.
AI can eventually help maintain that matrix.
