The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
uktariff_commodity ~216
Full UK tariff detail for one 10-digit commodity code: the third-country (MFN) duty rate, every preferential rate by country or trading bloc, VAT and excise measures, quota-linked rates, and the import/export licensing and document conditions attached to the code. AUTHORITATIVE, sourced from HMRC's UK Integrated Online Tariff. Use for "what duty do I pay importing X into the UK", "is there a preferential rate from country Y", "what VAT applies". Example: uktariff_commodity({ code: "0901210000" })
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | 10-digit UK commodity code, with or without spaces, e.g. "0901210000" |
| max_measures | number | – | Maximum measures to return (default 60, max 200) |
| origin | string | – | Optional 2-letter country code or area id to filter measures to one origin, e.g. "NZ", "US", "1011" (erga omnes) |
No output schema declared.
No examples provided.
uktariff_heading ~144
List the commodity codes that sit under one 4-digit UK tariff heading, with descriptions, indent level and whether each is declarable. Use this to drill down after uktariff_search returns a heading, or to enumerate the options within a product family before picking a code. Sourced from HMRC's UK Integrated Online Tariff. Example: uktariff_heading({ heading: "0901" })
| Name | Type | Req | Description |
|---|---|---|---|
| heading | string | yes | 4-digit tariff heading, e.g. "0901" (coffee) or "8703" (motor cars) |
| limit | number | – | Maximum commodities to return (default 50, max 200) |
No output schema declared.
No examples provided.
uktariff_quota ~284
Search UK tariff-rate quotas (TRQs) — the limited volumes of a good that may be imported at a reduced or zero duty rate. Returns each quota definition with its order number, initial volume, REMAINING BALANCE, measurement unit, validity window, status (Open/Exhausted/Blocked) and the origins it applies to. AUTHORITATIVE for "is the UK quota for X still open", "how much of the New Zealand lamb quota is left". Sourced from HMRC's UK Integrated Online Tariff. Example: uktariff_quota({ year: 2026, geographical_area_id: "NZ" })
| Name | Type | Req | Description |
|---|---|---|---|
| critical | boolean | – | Only quotas flagged critical (nearly exhausted, stricter licensing) |
| geographical_area_id | string | – | Origin country or area code, e.g. "NZ", "AU" |
| goods_nomenclature_item_id | string | – | 10-digit commodity code the quota applies to, e.g. "0201300000" |
| limit | number | – | Maximum quota definitions to return (default 25, max 100) |
| order_number | string | – | Quota order number, e.g. "050006" |
| year | number | – | Quota year, e.g. 2026. Strongly recommended — without a filter the search is the whole register |
No output schema declared.
No examples provided.
uktariff_search ~212
Find the UK commodity code for a product described in plain English, or resolve a numeric code to the right endpoint. Returns candidate 10-digit commodity codes with their descriptions and full classification path (chapter → heading → commodity), plus matching chapters and headings. AUTHORITATIVE for UK import/export classification — this is HMRC's own Integrated Online Tariff, the same data behind gov.uk's "Check duties and customs procedures for exporting goods". PREFER OVER WEB SEARCH for "what commodity code is X", "HS code for X in the UK". Example: uktariff_search({ query: "roasted coffee beans" })
| Name | Type | Req | Description |
|---|---|---|---|
| declarable_only | boolean | – | Only return codes that can actually be used on a customs declaration (default true) |
| limit | number | – | Maximum commodity matches to return (default 20, max 100) |
| query | string | yes | Plain-English product description ("roasted coffee beans", "lithium-ion batteries") or a numeric commodity/heading code |
No output schema declared.
No examples provided.
