About Tariff Notices

Tariff Notices tracks tariff, customs, sanctions, export-control, port, and freight changes that affect U.S. importers, and ranks them by importer impact so the items that need action surface first. Every signal links to its primary source.

Verified and developing signals

Verified signals have been checked by an editor against the primary source (the Federal Register notice, agency bulletin, or docket itself), including dates, deadlines, docket numbers, and HTS codes. They carry a plain-English brief with action items.

Developing signals come from the automated official-source monitor. They restate what the notice says and are clearly marked as unreviewed; confirm scope and dates against the linked notice before acting.

How signals are scored

Every signal gets a 0–100 impact score built from six factors. The full breakdown is shown on each signal's page.

Source authority: How authoritative the underlying sources are. Federal Register notices and agency bulletins score highest; trade media and commentary score lower.
Business impact: How directly the change affects importer costs or operations: duty rates, cash deposits, exclusions, filing requirements, or port flow.
Freshness: How recently the development was published or materially updated.
Corroboration: Whether multiple independent sources confirm the same facts.
Urgency: How soon action is required. Open comment windows, effective dates, and filing deadlines raise urgency.
Diffusion: How widely the development is spreading across trade press and practitioner channels.

How the feed is ranked

The Top view starts from the impact score and keeps the feed current: items lose a little ranking weight each day after their first three days, verified briefs and higher severity rank higher, open deadlines within 30 days rank higher, and items whose deadline has passed rank lower. Repeated routine notices with identical titles (such as a run of OFAC designation notices) are folded into one entry.

Latest lists everything newest first, Deadlines shows open comment windows, hearings, and filing dates soonest first, and For you boosts signals that match your watchlist and your feedback on this device.

Update cadence

The official-source monitor runs once a day at 13:30 UTC (7:00 p.m. India Standard Time) and publishes new developing items automatically. Editorial briefs are added and updated separately after review against primary documents.
