What this tool does

Entry Self-Audit lets an importer of record check its own filed entries. You upload the ES-003 (Entry Summary Line Tariff Details) export from CBP's ACE portal, and the tool re-runs every tariff line through ETDETA's own Chapter 99 tariff-stacking engine, then compares the modeled duty against what your broker actually paid — line by line.

Each line is flagged Potential overpayment (potentially recoverable), Potential underpayment (duty potentially owed), Missing / extra Chapter 99 codes, or Additional information required, with a layer-by-layer, reproducible breakdown so you can see exactly where the declared duty differs. Figures are modeled estimates of the layers we can price — take any finding to your licensed customs broker.

Who should use it

Importers of record, trade-compliance and finance teams reviewing their own filed entries for duty errors, refund opportunities and missing tariff codes before liquidation or protest deadlines.

What data it checks

Every tariff line in your ES-003 export, re-priced through the Chapter 99 stacking engine.
Declared duty vs. modeled expected duty, per line and per layer.
Missing or extra Chapter 99 (9903) codes — e.g. Section 301 / 232 / IEEPA layers.
Layer-by-layer deltas with concrete PSC / protest deadline references.

How to use it

Export your ES-003 (Entry Summary Line Tariff Details) report from ACE, or get it from your broker.
Upload or paste the CSV — it is processed for this audit only and not stored.
Review each line flagged Potential overpayment, Potential underpayment, Missing-code or Additional-information-required, with the layer-by-layer math.
Take any finding to your licensed customs broker to file a PSC or protest.

What the results mean

A per-line audit: Potential overpayment / Potential underpayment / Missing-code / Additional information required, with modeled exposure and recovery totals.
A reproducible layer-by-layer table (expected vs. filed vs. delta) for each flagged line.
Suggested next step (PSC vs. protest) with deadline references to verify.

Example searches

China entry missing the Section 301 layer — Flag potential underpayment where a 9903 code was not stacked.

Duty charged on an excluded line — Flag a potential overpayment that may be recoverable.

Mixed multi-line entry — Re-price each line and total modeled over- / underpayment exposure.

Try any of these in the tool.

What this tool does not determine

It checks additional-tariff (Chapter 99) layers only, and figures are modeled estimates of the layers we can price — the true delta may be larger.
It does not verify your HTS classification, customs value or country of origin, and does not cover AD/CVD.
Conditional lines (e.g. Section 301) and 'info required' lines are not resolved and are not zero — verify them with CBP / official sources.
A 'no discrepancy detected' result does not mean the entry is fully compliant. It does not file PSCs or protests and is not customs-broker, legal or tax advice.

FAQ

What file do I upload?

The ES-003 (Entry Summary Line Tariff Details) report exported from your ACE account or provided by your customs broker, as CSV. It is used only for this audit and is not stored.

Is this a filing or customs-broker advice?

No. It is a self-check diagnostic for the importer of record. It does not file PSCs or protests with CBP and is not your customs broker, attorney or advisor. Take any findings to your licensed broker.

Are the over- / underpayment figures final?

No — they are modeled estimates of the Chapter 99 layers the engine can price. The true delta may be larger, and eligibility and deadlines for any refund must be verified.

Does it cover AD/CVD or my HTS classification?

No. It checks additional-tariff (Chapter 99) layers only. It does not verify HTS classification, customs value, origin, or AD/CVD.

Is my uploaded data stored?

No. Uploaded data is used only for this audit and is not stored. You, the importer of record, remain responsible for exercising reasonable care.
