Nothing serious here today

Today is the operative word: we check US Tariff Lookup every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

estimate

estimate_us_duty

Applies the governing ad valorem rate for an HTS code to a customs value and returns the indicative duty, with the free-trade rate shown separately when the origin qualifies. It states plainly what is excluded rather than presenting a total that looks complete. Use it for a directional landed-cost figure, never as a customs declaration.

hts

find_hts_code

Search the official US Harmonized Tariff Schedule by plain-language product description and get back candidate HTS lines with their duty rates. Classification is the hard part of importing and the usual place a costly mistake is made, so this returns several candidates with their descriptions rather than pretending there is one obvious answer.

lookup

lookup_us_duty_rate

Given a US HTS code, returns the duty rate that actually applies, resolving the common trap that rates sit on the 8-digit line while the 10-digit statistical lines underneath are blank and inherit. Optionally pass the country of origin to see whether a free-trade rate is available. Always reports what is excluded, because trade remedies such as Section 301 are not in this data and can dwarf the base rate.

US Tariff Lookup — questions

Answers built from our own checks of this server.

What can US Tariff Lookup do?

It exposes 3 tools, read directly from the server on our last check. Among them: estimate_us_duty, find_hts_code, lookup_us_duty_rate. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is US Tariff Lookup working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 88 of 88 checks got a reply (100.0%), average response time 95 ms. The bar chart above shows every period we have measured.

How do I connect US Tariff Lookup?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does US Tariff Lookup need an API key?

No. US Tariff Lookup completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is US Tariff Lookup?

It answers our handshake in 95 ms on average, which is faster than 85% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is US Tariff Lookup open source?

Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
