If your company manufactures vehicles for the European market — passenger cars, trucks, buses, agricultural or industrial machinery — there is a regulatory clock ticking that few executives outside Brussels are paying attention to. On 5 July 2026, paper-based Certificates of Conformity become legally invalid across the entire European Union. From that day forward, every new vehicle entering the EU registration system must carry an electronic Certificate of Conformity (eCOC) — a structured XML document, signed with a qualified electronic seal, and routed through the EUCARIS network.
The consequences of non-compliance are not theoretical. Without a validly signed eCOC, vehicles cannot be registered, cannot be type-approved, and cannot be legally sold in any of the 27 Member States. For non-EU manufacturers, this is a direct threat to market access. For Tier-1 exporters with thousands of units in transit, it is an operational emergency.
Regulation (EU) 2018/858 — the framework governing the approval and market surveillance of motor vehicles — establishes that the Certificate of Conformity, until now a printed document accompanying each vehicle, must be replaced by a machine-readable XML file built to the IVI (Information of Vehicle Identification) standard.
Three requirements define a valid eCOC:
Distribution via EUCARIS — the European Car and Driving Licence Information System, accessed through National Access Points (NAPs) in each Member State.
Miss any one of these three, and the eCOC is rejected. There is no manual fallback, no grace period for the document itself, no national workaround. The system is designed to be fully automated and uniformly enforced from Lisbon to Helsinki.
On the surface, signing an XML file sounds like a routine IT task. In practice, the eCOC mandate exposes a gap that most non-EU manufacturers have never had to close: they do not have access to a qualified electronic seal recognised by EU authorities.
A standard SSL certificate, an internal corporate signature, or even an advanced electronic signature issued outside the eIDAS framework will not pass validation. The European Commission’s verification systems check three things automatically: the certificate chains back to a QTSP listed on the EU Trusted List; the seal is a qualified seal — not advanced, not basic; and the XAdES envelope is correctly formed. Anything less, and the eCOC is invalid.
For a manufacturer producing 500, 5,000, or 50,000 vehicles per month destined for the EU, this also means the signing process must be industrial: automated, batch-capable, integrated into the production management system, and resilient enough to handle peak volumes without human intervention. A manual signing workflow simply will not scale.
ANF AC is a Qualified Trust Service Provider accredited by the Spanish Ministry of Economic Affairs and Digital Transformation under the eIDAS Regulation. We are listed on the EU Trusted List, which means our seals are automatically recognised by registration authorities across all 27 Member States — without bilateral agreements, country-by-country adaptations, or local intermediaries.
Our eCOC compliance package includes four integrated components:
A digital certificate issued in your company’s name, functioning as your official European seal. It carries the highest legal presumption of authenticity and integrity available under EU law — equivalent in effect to a notarised corporate signature.
A REST API that applies a qualified electronic signature to your eCOC XML files in the XAdES format required by Regulation (EU) 2018/858. Integrates directly into your production management system or your technology partner’s platform (for example, eSign Global).
Sign thousands of eCOCs in a single unattended operation. Built for high-volume production lines where every vehicle rolling off the assembly line needs a valid certificate before it can ship.
Validation reports admissible as expert evidence before EU courts and registration authorities — useful when disputes arise over a certificate’s authenticity or a vehicle’s registration history.
Integration is not a one-week project. Obtaining a Qualified Seal requires identity verification of legal representatives. Connecting an API to a production system requires testing, sandbox validation, and coordination with internal IT teams. Configuring batch flows for peak volume requires staging and load testing. Most manufacturers who begin implementation today will need three to four months before they are production-ready.
With the deadline of 5 July 2026 fixed in EU law, the manufacturers who delay are the ones who will face shipping freezes, customs delays, and lost quarters.
ANF AC’s automotive regulation team is currently onboarding manufacturers, exporters, and signature platforms preparing for the July 2026 mandate. We offer a structured path to compliance:
Don’t wait until Q2 2026 to start your integration. Every week of delay is a week closer to a hard deadline with no extension.
