- How often is the US Tariff Tracker updated?
- Nightly. The `/api/cron/tariff-tracker-refresh` job reads new CBP CSMS bulletins, Federal Register notices, and USITC HTS overlay changes at 07:00 UTC and appends any new entries to the top of this page. Effective dates and citations are preserved verbatim from the source.
- What tariff regimes does this track?
- Section 122 (IEEPA reciprocal), Section 301 (China Lists 1-4A + renewals), Section 232 (steel, aluminum, and derivatives), IEEPA fentanyl/border tariffs, Chapter 99 overlays, AD/CVD case updates from USITC EDIS, and any Presidential proclamation adjusting an HTS rate.
- Where does the data come from?
- Primary sources only: CBP CSMS (customs bulletins), Federal Register (rule text), USITC HTS (live rate schedule), USITC EDIS (AD/CVD dockets), and USTR (Section 301 exclusion determinations). No second-hand quoting. Every entry links to its source document.
- Can I get an alert when a tariff on my HS code changes?
- Yes. The LandedFees dispatch-alerts subsystem monitors Chapter 99 overlays and CBP CSMS bulletins by HTS-4 chapter and can email you when a rate change affects your saved shipments. Sign up at `/dashboard` and add your HS codes to the watchlist.
- Is this page cacheable / linkable?
- Yes. The URL `https://www.landedfees.com/en/us-tariff-tracker` is permanent. Dated entries append to the top. Prior entries never disappear. Safe to bookmark, cite, or embed.
