| Tool | Description | Behaviour |
|---|---|---|
| lookup_hts_base_rate | Look up a fresh simple MFN general duty field from TariffsChart’s USITC HTS data. Includes source revision, date and excluded layers. Base-only: never treat this as the final import tariff. Complex or stale rates may be unavailable; use review_import_duty for quantity-based duties. | Read-only |
| review_import_duty | Review an import duty stack with official sources, known subtotals, missing inputs and unresolved applicability. Provide the real USD customs value and entry date. Unknowns stay unresolved; user review states are scenario assumptions. Do not infer a final duty from a known subtotal. | Read-only |
