Post-verification of origin certificates in the issuing country
How customs authorities verify origin certificates after importation and what it means for your compliance.
Post-verification is the procedure by which the customs authorities of the importing country have the authenticity and accuracy of a proof of origin verified by the customs authorities of the exporting country. It is a fundamental enforcement instrument in the preferential origin system, designed to detect fraud and errors after goods have already been imported and the preferential tariff has been applied.
Legal basis
The post-verification procedure is anchored in:
- Union Customs Code (UCC), Regulation 952/2013, Articles 59 and 116.
- Delegated Regulation 2015/2446, Articles 109-111.
- Specific trade agreements, which contain their own verification clauses (e.g., Protocol on Rules of Origin in the EU-UK TCA).
When post-verification is initiated
Customs authorities of the importing country may request post-verification when:
- There is doubt about the authenticity of the proof of origin.
- A risk analysis gives reason for further investigation.
- A random sampling control programme is in place.
- Third-party information indicates possible irregularities.
- An administrative error is suspected in the proof of origin.
The post-verification procedure step by step
Step 1: Verification request
The customs authority of the importing country sends a formal verification request to the customs authority of the exporting country. The request includes:
- Copy of the proof of origin to be verified (EUR.1, origin declaration, etc.).
- Reason for the request.
- Any specific questions about the product or its origin.
Step 2: Investigation by exporting customs
The customs authority of the exporting country conducts an investigation at the exporter's premises:
- Review of production records.
- Verification of supplier declarations.
- Review of the origin calculation.
- Possible on-site visit.
Step 3: Response to the importing country
The exporting customs authority reports its findings to the importing customs authority. The response confirms whether the proof of origin is:
- Valid: origin was correctly determined.
- Invalid: origin cannot be confirmed.
- Partially valid: for some products on the certificate origin is correct, for others it is not.
Step 4: Decision by the importing country
Based on the response, the customs authority of the importing country decides on:
- Maintaining the preferential tariff.
- Withdrawal of the preference and recovery of the duty owed.
- Possible fines or criminal prosecution in cases of fraud.
Timelines
| Phase | Timeline |
|---|---|
| Verification request | No fixed deadline, but typically within 3 years of import |
| Response deadline exporting country | Maximum 10 months (UCC); some agreements specify 6 months |
| If no response | Importing country may refuse preference |
Consequences of a negative post-verification
| Consequence | Explanation |
|---|---|
| Duty recovery | Difference between preferential and normal tariff rate, plus interest |
| VAT correction | If the customs value changes |
| Fine | For attributable errors or negligence |
| Criminal prosecution | For intentional fraud |
| Reputational damage | With customs authorities and trade partners |
How to prepare for post-verification
- Retain all origin documentation for at least the statutory retention period (3 years after the year of export, longer in some member states).
- Keep the origin calculation traceable: production figures, BOM (bill of materials), supplier declarations, and purchase invoices must be mutually consistent.
- Maintain current supplier declarations covering the entire delivery period.
- Document the origin rule that was applied, including the calculation (value percentage, tariff shift, specific processing).
- Designate a contact person responsible for responding to verification requests.
- Conduct internal audits on your origin dossiers before customs does.
Post-verification and digital origin management
Companies that maintain their origin records digitally and in a structured manner can respond more quickly and accurately to verification requests. A well-designed origin management system links supplier declarations, production data, and origin calculations to the specific consignments for which proofs of origin were issued.
Post-verification is not an exception but a structural part of the preferential origin system. Preparation does not start at the verification request, but at the moment of the origin determination itself.
