## MCP tools (2)

### `lookup_hts_code` (~88 tokens)

Search for HTS (Harmonized Tariff Schedule) codes by description or numeric prefix. Returns up to 12 matching codes with descriptions. Use this before calculate_tariff when you only have a product description.

Input parameters:

- `query` (string, required): Product description (e.g. "athletic footwear") or HTS code prefix (e.g. "6404"). Min 2 characters.

### `calculate_tariff` (~203 tokens)

Calculate the full stacked US import tariff rate for an HTS code from a specific origin country. Returns: base rate, each additional layer (Section 301, IEEPA, reciprocal), total current rate, and the projected rate after the November 10, 2026 cliff. Optionally computes dollar impact from annual import volume.

Input parameters:

- `annual_import_value_usd` (number): Optional. Your annual import value in USD. If provided, the response includes the dollar cost of current duties and the additional cost from the Nov 10 cliff.
- `hts_code` (string, required): HTS code — at least 6 digits, up to 10 (e.g. "6404.11" or "6404110000"). Dots and spaces are ignored.
- `origin_country` (string): ISO-2 origin country code (e.g. "CN" for China, "VN" for Vietnam, "MX" for Mexico). Default: CN.
