No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/uktariff_heading for the schema, then POST the same URL with its arguments for the data.

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” })

Parameters

`heading`	string	yes	4-digit tariff heading, e.g. “0901” (coffee) or “8703” (motor cars)
