Where the numbers come from
Duty rates are read from the US International Trade Commission's tariff schedule. Every build checks each code and surcharge list, and nothing is published if a check fails.
Each page states its data version and the date it was checked.
For AI assistants
Each tool comes with prompts: paste one with your numbers into ChatGPT, Claude or DeepSeek and it calculates with the current rules.
The site has llms.txt and a Markdown copy of every page, so AI assistants can read and cite it.
