Frequently Asked Questions

USTradeStack's /classify tool ranks probable 10-digit Harmonized Tariff Schedule codes using AI-assisted vector similarity against verified chapter notes and CBP cross-rulings. The free output shows your top three candidates with explanations so you know why each code was suggested. For a broker-grade verdict, the $29 HTS Classification Report pins a single 10-digit code, flags Section 301 list placement, and notes admissibility concerns (AD/CVD, UFLPA, ITC investigation).

Tariff rates on /tariffs/watch are refreshed by the tariffs-watch-refresh cron every Monday at 08:00 UTC, after the daily services/federal-register-monitor.js ingest pulls verbatim Federal Register and CBP CSMS notices from primary sources. Each entry on the brief links to its source federalregister.gov/d/<document_number> URL — no paraphrase, no secondhand summary.

Free tools stay free: /classify, /calculate, /compliance-check, and /tariffs/watch. Subscription tiers (Starter / Professional / Enterprise) are billed through Stripe Connect — see /pricing for current rates and the /admin/funnel dashboard for tier-conversion trends. Paid one-time reports, each with a single deliverable you can hand to your broker: $29 HTS Classification Report, $49 Landed Cost Analysis, $79 Trade Agreement Qualification, $99 Supplier Risk Assessment, $199 Compliance Audit Report.

Yes. From any classification on /classify, the in-results broker-handoff button emails the full 10-digit code, your product description, and the duty exposure to a trade attorney, compliance consultant, or licensed customs broker from /vendors. Behind the scenes: POST /api/internal/classify/email-broker delivers the brief to the selected vendor (logged-in users only).
