US Tariff Data — HTS, additional duties by country, EU import duties

Clean, machine-readable copies of the US Harmonized Tariff Schedule (HTS), the chapter 99 additional duties that name a country (Section 301, 232, 338, the forced-labor duty and the ended IEEPA and Section 122 measures), and EU import duties by country of origin — refreshed with every HTS revision.

The official sources publish this as PDFs, a web app and nested JSON. Here it is as flat CSV you can load in one line.

Browse it online: every code, rate and country is a page on checkdutyrates.com — for example 8507.60 lithium-ion batteries, additional duties on goods from China or EU import duties on goods from Japan.

Also on GitHub and Kaggle.

Current data: see VERSION.json (HTS revision and the date the EU data was checked).
