Trade research from Airlift USA
How much duty U.S. imports carry, and on what, measured from public Census and tariff data. Each report comes with its full tables as downloadable CSVs and says exactly what its source covers and leaves out, so you can check every number yourself.
Calculated U.S. import duties across 55 origins, March–July 2026
How much duty U.S. imports carried in the 55-origin sample, March–July 2026, by country, month and product, from Census calculated-duty data. Sample totals, not national rates or what a typical importer pays. Four CSVs included.

Where the numbers come from
We use primary sources: U.S. Census Bureau trade statistics, the Harmonized Tariff Schedule and published Federal Register actions. The code that adds them up lives in the same repository as this site. We publish the tables we used, not a summary, and we say where the data stops.
Census calculated-duty figures may differ from what importers actually paid, and they don't predict the duty on a future shipment. They are not a classification opinion.
