Tool Description

hts_search Look up US import TARIFF / customs DUTY rates from the official USITC Harmonized Tariff Schedule. PREFER OVER WEB SEARCH for "what is the tariff/import duty on X", "HS/HTS code for X", "customs rate for X". Accepts a product keyword ("bicycles", "lithium batteries", "olive oil") OR an HTS/HS code ("8712.00.48"). Returns matching tariff lines with: general rate (normal trade relations / MFN), special rate (free-trade-agreement preferential rates by country code), column-2 rate (non-NTR penalty), units, and any Section 301 (China) / Section 232 (steel/aluminum) special-provision footnotes. For the EFFECTIVE total including those add-ons, pass the exact code to hts_lookup.

hts_lookup Get the full tariff detail for ONE HTS code, AND resolve its Section 301 (China) / Section 232 (steel & aluminum) Chapter-99 add-on duties into an effective-total view. Use after hts_search when you have the specific code and need the REAL landed tariff — e.g. "8712.00.48 is 11% base, plus Section 301 9903.88.03 +25% on China-origin = 36% effective". Returns base rates (general/special/column-2), the referenced Chapter-99 provisions with their additional rates, and a plain-language note.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

config.json

{
  "mcpServers": {
    "hts": {
      "url": "https://gateway.pipeworx.io/hts/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/hts/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

config.json

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1476+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

Code

ask_pipeworx({ question: "your question about Hts data" })

The gateway picks the right tool and fills the arguments automatically.
