US import duties only. This view models tariff layers CBP assesses on goods entering the United States (MFN, §232, §301, §122, MPF, HMF, federal excise). Retaliatory tariffs imposed by other countries on US exports are excluded. Re-export scenarios require a separate analysis against the destination country’s schedule.

Tariff Batch

← Single-line modeler

Upload an HS list and get the stacked duty rate per line for directional analysis. Required columns are hts_code and country_code; optional columns fta_qualifying (true / false) and chapter98_scenario (standard / returned_unchanged / repaired_altered / assembled_abroad / temporary_import). The engine is the same calculateDutyStack that powers the single-line modeler, so Column 2, §232, §301, §122, Chapter 98 and FTA carve-outs all apply.

Batch output is directional. It excludes AD/CVD deposits, non-ad-valorem specific duty components, §232 absolute-quota fill status, and other caveats surfaced in the single-line modeler. Verify each filing against the USITC HTSUS and a licensed customs broker before submitting an entry.
