About TariffOS
Tariff intelligence for the companies that actually pay the duties.
What we do
TariffOS organizes selected U.S. tariff measures through their lifecycle — threatened, announced, in effect, paused, litigated, or struck down — and links each summary to an official source. Public matching and scenario tools help structure further research without pretending to make a customs determination.
Built honestly
We are pre-launch and we say so. No invented customer logos, no fake testimonials, no fabricated user counts. Every data point on this site is hand-curated from official sources and carries its citation and verification date. Where data is a bundled snapshot rather than a live feed, the page says so.
Who it's for
Importers, procurement teams, customs professionals, researchers, and trade-compliance teams. Public tools and intelligence pages are open to everyone; account plans add a personal catalog, CSV import, exposure matching, repricing scenarios, origin comparison, and analyst questions within stated limits.
