Key takeaways

  • "Import duty" on a CBP entry usually blends several regimes; the refundable piece here is the IEEPA component.
  • The calculator estimates only what the source file's amount fields support — no rate recomputation.
  • Section 301, Section 232, AD/CVD, and drawback refunds are outside this tool's scope.
Direct answer
What does an import duty refund calculator estimate?
It estimates the IEEPA portion of paid import duty that may be refundable, based on the CSV's visible amount fields and Chapter 99 signals. It does not estimate non-IEEPA refund regimes.
Direct answer
Is every import duty refundable right now?
No. Refundability depends on the duty regime, entry status, liquidation posture, and CBP guidance. This calculator is scoped to IEEPA exposure, which is the refund regime the site focuses on.
Direct answer
What CSV should I use?
A broker export or ACE ES-003-style report with entry number, entry date, importer of record, isolated IEEPA amount, Chapter 99 code, and liquidation or status field is the strongest input.

What to decide next

Use the source file to decide whether to estimate, request better data, or move into declaration-pack prep.

What this calculator covers
The calculator is scoped to IEEPA refund exposure. Keeping the scope explicit prevents an inflated 'refund' number that mixes in duties that are not actually refundable right now.
  • IEEPA Chapter 99 exposure visible in the source file
  • Entry-level rollups by importer of record
  • Duplicate, missing-amount, and weak-field warnings
  • Liquidation, protest, drawback, reconciliation, and warehouse signals that affect routing
What this calculator does not cover
Keeping these out of the total is what makes the estimate conservative and defensible.
  • Section 301 China-origin duty refunds
  • Section 232 steel, aluminum, or derivative refunds
  • AD/CVD and surety-paid refunds
  • Drawback (manufacturing, unused-merchandise, or substitution)
  • Standard MPF, HMF, or non-IEEPA duty relief
How 'import duty' maps to the IEEPA portion
A single broker duty column often aggregates base duty, MPF, HMF, Section 301, Section 232, and IEEPA. The calculator relies on isolation rather than reconstruction.
  • If the CSV has a dedicated IEEPA column or flag, it is used directly
  • If Chapter 99 lines identify IEEPA rows, their amounts are summed
  • If the file only exposes a blended duty total, the estimate is marked as low-confidence
  • No rate recomputation is performed — the tool does not re-rate entries

Import-duty-to-IEEPA estimation workflow

  1. 1

    Start with the customs CSV you have

    Use the cleanest available file: a broker export, ACE ES-003 report, or entry-level internal CSV.

  2. 2

    Check how the file reports duty

    Confirm whether IEEPA is isolated or blended into a single duty column, and review any Chapter 99 code columns the estimator detects.

  3. 3

    Review the confidence signals

    Treat the estimate as directional when amounts are blended. Request a cleaner export instead of modeling around missing fields.

  4. 4

    Choose the next step

    Escalate to broker follow-up, counsel review, or paid Declaration Pack prep when the IEEPA portion of the import duty is clearly supported by the file.

FAQ

Common questions about import duty calculator

No. It is scoped to IEEPA exposure. Section 301, Section 232, AD/CVD, and drawback refunds use different data and should be handled in their own workflows.
