🟢lookup_hts_base_rate(hsCode)
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.

}🟢review_import_duty(hsCode, origin, customsValue, entryDate, loadedDate, ...)
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.
