Where the margin goes

    Sensitivity check

    See what breaks the margin before you buy inventory.

    Trust notes

    Use this as a planning model, not a customs filing tool.

    ImportMargin helps sellers pressure-test supplier quotes before ordering inventory. It does not replace official HTS classification, customs brokerage advice, tax advice, or compliance review. Read the data sources and accuracy notes before relying on any estimate.

    • Calculations run in your browser; no sign-up or file upload is required.
    • Tariff scenarios are planning examples and must be verified in official sources.
    • Final duties depend on classification, origin, materials, function, and current trade actions.

    Tariff modeling

    Stress-test duty before inventory is on the water.

    Use conservative presets as a quick downside check, then verify the final HTS classification before committing to a purchase order.

      Accuracy checklist

      Four assumptions to verify before trusting the margin.

      The calculator is useful only when the quote assumptions are visible. Confirm these before ordering inventory.
