I made a simple tariff calculator extension for Amazon.
It queries gemini flash 2.0 to determine the category, and then matches it with the corresponding tariff category.
Fun quick hack – it does brick a little – but the majority of the code was cobbled by a first pass of Claude Code

I would argue the 40% estimate, even though probably correct some of the time, is very often vastly overestimated. Consumers mostly pay for last-mile delivery, marketing, and the retailer's margin. The price paid in bulk to manufacturers is usually a very small fraction of the retail price.
Seems like it changes hour to hour.
