Duty by country: what the origin changes on the same HS code
One page per product · every origin that shipped it to the US in the Census month · the spread between the cheapest and the dearest
The Column 1 duty rate is a property of the HTS line, not of the origin country: every origin pays the same base rate on the same line. What differs is the Chapter 99 stack — the additional duties written against specific countries. That stack is what makes the same product cost 10% from one country and 48% from another. Each page below prices every origin that actually shipped the product, so the difference is measured rather than asserted.

How to read a page
Each product page lists every origin that shipped at least $100,000 of the code to the United States in the Census month, sorted cheapest first, with the Chapter 99 headings that produced each rate. The page's headline number is the spread: the difference between the cheapest and the dearest origin on the same HTS line. That number cannot be produced by reading the tariff schedule alone, because it depends on which countries are actually shipping.
Rates are this site's tariff engine's answer per origin; import values are the U.S. Census Bureau general-imports series. Pages are rebuilt from those sources and a gate re-prices every origin against the API on each build.
