Look up or search the US Harmonized Tariff Schedule (HTS / HS codes). Pass code for an exact HTS number (dots optional) — returns that line plus its 10-digit statistical suffixes with duty rates. Or pass query for free-text search (e.g. 'electric toothbrush', 'roasted coffee') → ranked candidate HS codes by hierarchical heading. Each result: htsno, chapter, description, full heading path, units, and duty rates (general/MFN, special/FTA, column-2). ~29.6k lines, public-domain USITC data. The deterministic backbone for tariff classification in import/export and ERP item setup.
