How It Works

Two-Phase Detection

Fast alerting with authoritative confirmation.

Phase 01 — Preliminary

Federal Register Scan

NLP pipeline ingests new Federal Register documents within minutes of publication. Extracts tariff-relevant actions, flags affected HTS codes, and delivers preliminary alerts.

< 15 min latency

Phase 02 — Confirmed

HTS Schedule Diff

Authoritative comparison against the official USITC Harmonized Tariff Schedule. Byte-level diff produces exact rate changes with legal citations.

Within 24 hours
