Turn fragmented data into audit-ready insights

When a tariff program is removed or a new trade shift occurs, manual recovery is time-consuming, expensive, and leaves you exposed. Legacy systems — built for recording transactions, not modeling value chains — cannot answer the regulator’s most critical questions:

  • 01

    How was classification determined?

  • 02

    What documentation supports the country of origin?

  • 03

    Why was a specific duty paid?

With Altana, you can:

  • Identify Exposure

    Pinpoint exactly where you were impacted by a tariff program (like IEEPA) across thousands of entries.

  • Recalculate Accurately

    Toggle off or introduce new measures, and the system automatically re-stacks remaining tariffs and recalculates total duty exposure systematically and consistently.

  • Substantiate Claims

    Use the documented compliance determinations — tied directly to the product’s underlying value chain — to clearly support the difference between what was paid and what should have been paid.
