  • The whole duty stack

    Not just the MFN rate. Section 232 and 301 surcharges, IEEPA measures, antidumping and countervailing flags, and the Chapter 99 headings that change what you owe.

  • Claimable exclusions

    Toggle an exclusion on and instantly see how it affects your total duties. TariffSense automatically recalculates all applicable tariffs, accounting for how duty lines stack.

  • Trade measure warnings

    Flags when a code appears on current AD/CVD, SIMA or tariff-rate quota lists, and surfaces partner government agency requirements where we hold them.

  • USA and Canada, any origin

    The same engine our customers use for entry audits, covering both US and Canadian imports.
