One call returns the current, source-backed total US duty rate—every stacked layer plus MPF/HMF and landed cost—so your agent stops guessing tariffs and importers get an answer without an HTS code.
LLMs hallucinate the thing that changes most—stacked 2026 US tariffs and MPF/HMF. GroundTruth anchors them in maintained, attributable customs facts.
We return structured, computed results with units and sources—no scraping, no guessing from a page of search links.
Official rates are monitored and the data store is recompiled on change. Refresh the deployment to propagate.
Drop it into Claude, Cursor, ChatGPT via MCP, or call the JSON HTTP API from any app.
MFN + forced-labor + Section 301/232 + MPF/HMF in one result, with confidence and a clear disclaimer.
Clear schemas, quickstarts and copy-paste code get developers to a successful call in minutes.
Every value carries an effective date, verification status and official source URL.
Ask “how much duty and landed cost for a Bluetooth speaker from China?” and get the complete breakdown.

One understated duty figure triggers back duties, penalties and cargo holds. GroundTruth is priced like insurance, not software seats.
| Option | What it costs | Year 1 cost |
|---|---|---|
| One misclassified / miscalculated shipment | Back duties, customs penalties, demurrage and weeks of delay on a single entry | $5,000–$50,000+ |
| Customs broker per entry | $40–$150+ per entry, hundreds of entries per year — answers still not in your AI | $10,000–$40,000+ |
| Build & maintain it yourself | Engineer time to model stacked tariffs, plus permanent monitoring of federal register changes | $20,000+ / year |
| GroundTruth Enterprise | Monitored, source-backed rates inside your agent and apps — unlimited calls, alerts, done-for-you setup | $2,800 flat |
No call caps and no metering. If your traffic grows 10× or 100×, the price stays $2,800. We only ask that integrations use reasonable caching rather than hammering the endpoint in a loop.
Usually within hours. Your API key is issued and activated right after payment clears, and we do the MCP/API setup with you on a short onboarding thread.
Card, bank transfer or Payoneer — whichever is easiest. You request a secure payment link, pay once, and that’s the whole year.
We monitor official sources, recompile the data store and push updates. Enterprise customers also get rate-change alerts before the new rates take effect.
No — one annual payment is what lets us keep the price this low with unlimited usage and include onboarding and alerts. The 30-day refund makes the commitment risk-free.
$2,800 for a full year of unlimited, source-backed tariff answers — or every cent back within 30 days.
