Post-clearance compliance platform

Customs declaration audit software for UK, EU and US importers

Every declaration reconciled against source documents. Classification errors caught. Overpaid duty quantified. Recovery-ready data packs prepared for your broker. Per-tenant data isolation from day one.

Why customs declarations need auditing after filing

Your broker files declarations. That is their job. But who audits what was filed? The classification that was correct in 2024 may be wrong in 2026 after a tariff reclassification, a new trade agreement or a change in product composition. The transaction value that matched the invoice may not account for royalties, assists or subsequent proceeds that should have been included under WTO Valuation Agreement rules.

HMRC, Revenue, EU member-state customs administrations and US CBP all conduct post-clearance audits. HMRC announced 5,500 additional customs officers in 2025. CBP\'s Focused Assessment programme targets the highest-volume importers. When they arrive, every declaration in the review window is in scope.

Customs declaration audit software closes the gap between filing and compliance. It operates continuously, reviewing every entry as it arrives, comparing it against the source evidence, and flagging errors while correction windows are still open.

What the platform audits

Six audit dimensions applied to every declaration. AI-powered analysis with human-reviewed findings.

Classification audit

Every HS/CN code checked against product description, supplier documentation and historical classification patterns. Catches commodity-code drift, heading-level errors and subheading mismatches.

Valuation analysis

Transaction values benchmarked against trade statistics and prior entries. Flags undervaluation, overvaluation, inconsistent invoice currencies and missing adjustments for royalties, assists or freight.

Origin verification

Declared country of origin cross-referenced against supplier declarations, certificates of origin and rules of origin under each preferential trade agreement. Identifies preference under-utilisation.

Document reconciliation

FastNet™ IDP extracts data from invoices, packing lists and certificates. Every field is matched against the corresponding declaration. Discrepancies are flagged with the source document reference.

Duty exposure quantification

Financial exposure calculated per entry, per commodity code and per regime. Aggregated dashboards show total overpayment, total underpayment and net duty position across your entire portfolio.

Recovery-ready data packs

When overpaid duty is identified, the platform generates correction data packs formatted for HMRC C285, EU UCC Article 117, US Post-Summary Correction or formal protest. Your broker files; we prepare.

How customs declaration audit works in MyCustomsInfo®

1

Data ingestion

Declaration data is ingested from CDS, AES, ACE or any supported regime via API, SFTP or manual upload. FastNet™ IDP processes scanned invoices, certificates and packing lists into structured data.

2

Six-source reconciliation

Every entry is reconciled against six sources: the declaration itself, the commercial invoice, the packing list, the certificate of origin, the broker worksheet and the duty payment confirmation. Discrepancies are flagged at field level.

3

AI classification and valuation check

The Piers AI engine cross-references each tariff classification against the product description, supplier documentation, ruling databases and historical entries. Transaction values are benchmarked against trade statistics and prior shipments.

4

Financial exposure report

A compliance report is generated showing total overpayment, underpayment and net duty position. Each finding includes the declaration reference, the error type, the financial impact and the correction mechanism available.

5

Recovery-ready data packs

For every overpayment, the platform generates a correction pack formatted for the relevant mechanism: HMRC C285, EU UCC Article 117, US Post-Summary Correction or formal protest. Your broker files the correction using these packs.

Customs regimes supported

MyCustomsInfo® ingests declaration data natively from each system and maps fields to a common audit schema. Cross-regime comparison identifies inconsistencies when the same product enters different jurisdictions under different classifications.

Frequently asked questions about customs declaration audit software

What is customs declaration audit software?+
Customs declaration audit software is a post-clearance compliance tool that systematically reviews every import and export declaration after goods have cleared the border. It reconciles declared values, tariff classifications, countries of origin and preference claims against source documents including commercial invoices, packing lists, certificates of origin and broker worksheets. The aim is to identify errors before customs authorities do, recover overpaid duty and maintain a continuous audit trail.
Which customs regimes does MyCustomsInfo® cover?+
MyCustomsInfo® covers UK CDS (Customs Declaration Service), EU AES (Automated Export System) and member-state import systems, US ACE (Automated Commercial Environment) including Entry Summary data, Ireland's AIS, Canada CBSA CARM, Australia ICS, Switzerland e-dec, Singapore TradeNet and additional Nordic regimes. The platform ingests declaration data natively from each system and maps fields to a common audit schema for cross-regime comparison.
How does AI improve customs declaration auditing?+
Our Piers AI engine applies machine-learning classification models trained on millions of historical entries, transaction-value benchmarking against trade statistics, and natural-language processing to match product descriptions to HS/CN codes. It identifies statistical outliers in declared values, flags classification inconsistencies across the same product imported through different ports, and detects origin declarations that conflict with supplier documentation. AI reduces false positives compared to rule-based systems and learns from each client's correction history.
What documents does the platform reconcile against each declaration?+
The platform reconciles each declaration against the commercial invoice, packing list, bill of lading or airway bill, certificate of origin (preferential or non-preferential), supplier declarations, broker classification worksheets, duty payment confirmations and any applicable licences or permits. FastNet™ IDP (Intelligent Document Processing) extracts structured data from scanned and PDF documents, eliminating manual data entry.
Can the software identify duty recovery opportunities?+
Yes. Every audit pass quantifies overpaid duty arising from misclassification, incorrect valuation, underused preferential rates and missed reliefs such as Returned Goods Relief or Inward Processing Relief. The platform generates recovery-ready data packs for HMRC C285 claims, EU UCC Article 117 refund applications, US Post-Summary Corrections and formal protests under 19 USC §1514. Your licensed broker or customs agent files the correction; we prepare the evidence.
How is my data protected?+
Every client operates in a dedicated, per-tenant isolated environment. Your declaration data, origin certificates and broker worksheets are never co-mingled with another importer's data. The platform runs within ISO 27001/28000-aligned infrastructure, all data is encrypted at rest and in transit, and a mutual NDA and Data Processing Agreement are executed before any data is exchanged. GDPR and UK GDPR compliant throughout.
What is the difference between customs declaration audit software and an ERP customs module?+
An ERP customs module typically manages the filing workflow: it helps you create and submit declarations. Customs declaration audit software operates after filing. It reviews what was filed, compares it against source evidence, identifies errors and quantifies the financial exposure. The two are complementary. MyCustomsInfo® does not file declarations; we audit them. We identify, your broker acts.
How quickly can I see results after onboarding?+
Once data is received and a Data Processing Agreement is in place, the first compliance report is typically delivered within hours. For a full historical audit covering up to three years of declarations, the initial findings report is delivered within 5 to 10 business days depending on declaration volume. Ongoing monitoring is continuous: new entries are audited as they arrive via API or scheduled data feeds.
