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®
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.
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.
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.
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.
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.

|---|---|---|---|
| United Kingdom | CDS (Customs Declaration Service) | HMRC | CHIEF migration complete; CDS native |
| European Union | AES / Member-state import systems | National customs | SAD/NCTS/AES XML |
