Tariff & HS Code Duty Finder

Official4 tools

by nguyenhieuec

Find an HS code, HTS code or customs code, and read the customs duty or import tax.

app.openkrill/tariffs — Model Context Protocol (MCP) Server

The MCP server app.openkrill/tariffs finds candidate customs tariff codes for a product and returns the import duty for a selected code. It is intended to support tariff code discovery followed by import-duty lookup based on that code.

🛠️ Key Features

Find candidate customs tariff codes for a product
Read the import duty on a tariff code

🚀 Use Cases

Identify possible customs tariff codes for a given product
Look up import duty for a selected customs tariff code

⚡ Developer Benefits

Provides tariff-code candidate results to support downstream duty retrieval
Supports a two-step workflow: code discovery, then import-duty reading

find_tariff_codes

Use this when the user asks for the tariff code, commodity code, customs code, HS code, HTS code, Harmonized System code or customs classification for a product, for example "what is the tariff code for a ceramic flower pot in the UK?", "HTS code for a lithium-ion battery" or "which heading covers cotton t-shirts for import into the US?". Pass a plain description of the product and country GB (United Kingdom) or US (United States). Returns candidate codes from the official schedule, each with its description, the headings above it and whether goods are declared under it, plus a notice that they are candidates and not a binding classification. Do not use it to classify goods with certainty, to give a binding customs ruling, to compute shipping or landed cost, or for countries other than GB and US.

Parameters3

description	string	required	Plain description of the product: what it is, what it is made of, what it is used for. Or a code, to look that code up.
country	string	required	Destination of the goods, whose import tariff to read: GB (United Kingdom Global Tariff) or US (Harmonized Tariff Schedule). The EU and other countries are not covered.
limit	integer	optional	Most candidates to return. Default 8.

get_duty_rate

Use this when the user asks what import duty, customs duty, tariff, import tax or VAT applies to a tariff code or HS code, for example "what is the US duty on HTS 8507.60.00?", "what duty applies to UK commodity code 6914100000 from Vietnam?" or "what is under heading 6914 in the UK tariff?". Pass the code (4 to 10 digits, dots allowed), country GB or US, and originCountry when the user names where the goods come from. For a code goods are declared under it returns the description and the rate: for the UK the third-country duty, VAT rates as a list, the preferential rate and any additional duty for the origin, and other measures; for the US the general, special and column 2 rates and units. For a code that is only a heading it returns the lines beneath it instead. Chapter 99 additional duties for the US and quotas or trade remedies are not included. Do not use it for a landed cost estimate, for excise or customs-broker fees, or for legal advice.

Parameters3

code	string	required	Tariff code of 4 to 10 digits, with or without dots, for example 8517.13 or 6914900010.
country	string	required	Destination of the goods, whose import tariff to read: GB (United Kingdom Global Tariff) or US (Harmonized Tariff Schedule). The EU and other countries are not covered.
originCountry	string	optional	Two-letter code of the country the goods come from, for example VN. Adds that country's preferential rate (GB) or tells whether the column 2 rate applies (US).

submit_feedback

Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer. Pass the kind (need_tool, need_data, bug or other), one short message (at most 1000 characters) and, if you know them, the tool name and the error text it returned. Returns a ticket id. Feedback is not a chat: nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.

Parameters4

kind	string	required	need_tool: a tool you want. need_data: data a tool lacks. bug: something broke. other: anything else about the tools.
message	string	required	What you need or what broke, in plain words, at most 1000 characters. Links, email addresses and phone numbers are removed. Never include secrets or personal details.
tool	string	optional	Optional: the exact name of the tool on this server that the feedback is about, as tools/list shows it.
error	string	optional	Optional: for a failed call, the error text it returned, copied as you saw it. Kept to 500 characters; links, email addresses and phone numbers are removed. Never include secrets or personal details.
