Stable
PlatformCustoms entry audit software

Every entry, audited
before CBP does.

Entry Audit from Stable Software checks every line of your ACE ES-003 export: Section 232 and 301 codes, the value and origin filed with them, and duty and fee math. It surfaces the discrepancies that matter, with the reasoning behind each one.

What it does

What it checks,
and what happens next.

Every capability is built for the broker filing hundreds of entries a week. Not a generic audit tool retrofitted for customs.

01: RULE ENGINE

Every line checked for Chapter 99 errors.

Entry Audit runs each line of your ES-003 export through every rule for Chapter 99 structure, Section 232 and 301 applicability, duty math, and fees. Not a spot check. Every line, every entry.

02: CHAPTER 99 CHECKS

Spots trade-remedy codes that don't belong.

Flags a Section 232 code filed with no metal value or duty, a 232 code outside the steel and aluminum chapters, a 301 code on non-China goods, and duplicate or conflicting 9903 codes on one line.

03: DUTY & FEE MATH

Catches the arithmetic that triggers penalties.

Line duty is checked against entered value times rate, MPF against the per-entry cap, HMF against 0.125% of value, and each 9903 duty against its rate and covered value.

04: SEVERITY & REASONING

Know what's blocking, and why.

Each finding is marked Blocking, Warning, or Info, with the authority behind it and a plain-English explanation, so reviewers work the ones that matter first.

05: TRIAGE

Decide once. It sticks.

Reviewers accept or dismiss each finding. Re-run the batch and every decision carries forward, while fixed data closes its open findings automatically.

06: AUDIT TRAIL

Every decision, on the record.

Every finding keeps its rule, filed and expected values, suggested fix, and who accepted or dismissed it and when. Export a batch's findings to CSV in one click.

How it works

From ACE export
to corrected entry.

Four steps from an ACE export to audited entries, with your team in the loop on every finding that matters.

01: IMPORT

Upload your ACE ES-003 export.

Entry Audit reads the Entry Summary Line Tariff Details report (CSV or Excel) from the ACE Portal. Confirm the column mapping once and it is saved for the next upload. No re-keying.

02: AUDIT

Every line checked against every rule.

Chapter 99 structure, Section 232 and 301 applicability, duty math, MPF, and HMF are evaluated line by line, and discrepancies are raised with severity and the authority behind them.

03: REVIEW

Your team makes the call on each finding.

Reviewers see each finding, its rule, and its reasoning. Accept it or dismiss it; every decision is logged with who made it and when.

04: CORRECT

Hand the fixes to your filer.

Export the findings with filed and expected values and a suggested fix for each, ready for the post-summary corrections your filer submits.

Inputs and outputs

Reads the ACE report your firm already pulls.

Entry Audit works from the ES-003 export in the ACE Portal, so turning it on takes one file and a confirmed column mapping, not an integration project.

Common questions

What brokers ask us
before they turn it on.

A customs entry audit is a review of filed entry summaries (CBP Form 7501) to find duty, fee, and trade-remedy errors before CBP does, so they can be corrected (for example, with a post-summary correction your filer submits). Entry Audit from Stable Software automates the line-by-line checks on your ACE ES-003 export: Chapter 99 codes, duty math, MPF, and HMF.
Classification is about choosing the HTS code for an item before you file; Stable Software's Classification module is coming soon. Entry Audit reviews entries you have already filed, every line of the ES-003 export, for Chapter 99, duty, MPF, and HMF errors.
After. Entry Audit reads the ES-003 report of entries already filed in ACE, so you can quantify exposure across historical entries and correct errors before CBP finds them.
On every line, Entry Audit flags a Chapter 99 remedy code filed with $0 value and $0 duty (or with a rate but no duty), a Chapter 99 code filed as the primary classification with no base HTS number, the same 9903 code twice on one line or two different Section 301 subheadings on the same line, a Section 232 code on goods classified outside chapters 72, 73, and 76, and a Section 301 (9903.88) code on goods not of China origin. It also checks line duty against entered value times rate, MPF against the per-entry ceiling and fiscal-year maximum, HMF against 0.125% of value, each 9903 provision's duty against its rate times covered value, and that no provision's covered value exceeds the line value. Checks against the live HTS are next.
Entry Audit gives your filer what a PSC needs: each finding carries the filed value, the expected value, and a suggested fix, exportable to CSV in one click.
Every audited batch keeps its findings, the authority cited, who accepted or dismissed each one, and when, exportable to CSV in one click.
