TariffDesk monitors US government sources — the Federal Register, USITC Harmonized Tariff Schedule, and USTR Section 301 lists — for tariff rate changes and alerts customs brokers and importers before those changes hit their shipments. Brokers get a multi-client dashboard to track HTS codes across all their clients, with automated white-labeled email alerts sent directly to each client. The platform computes total effective duty rates by country of origin including all active surcharges (Section 301, Section 232, Section 122) so importers know their actual landed cost, not just the base rate.
