CITAQ
EU DPP Compliance

The EU Digital Product Passport mandate starts February 2027.
CITAQ is designed to get you DPP-ready.

The EU's Ecodesign for Sustainable Products Regulation (ESPR) requires machine-readable, cryptographically verifiable product records for battery products from February 2027. Textiles and electronics follow. CITAQ's verification infrastructure is designed to support these requirements as part of product verification.

What the Law Requires

The EU DPP is a data structure, not a document.

The EU Digital Product Passport is not a certificate. It is a machine-readable data record that must be:

  • →Accessible via a standardized digital link (QR code or RFID)
  • →Cryptographically verifiable — the record cannot be tampered with
  • →Continuously updated — revocations and updates must propagate within a defined window
  • →Sector-specific — batteries have different required fields than textiles
For batteries specifically, the DPP must contain:
  • Product identification (manufacturer, model, serial number)
  • Technical specifications (energy capacity, nominal voltage, charge cycle life)
  • Safety certifications (IEC 62133, UN 38.3, CE marking)
  • Material composition (critical raw materials, recycled content percentage)
  • Carbon footprint per kWh
  • Recycling and disposal information
  • Supply chain traceability data
  • Manufacturer contact information for waste management

All of this data must be linked to verifiable evidence. A DPP record that contains unverifiable self-declarations does not satisfy the regulation.

CITAQ + EU DPP

CITAQ verification is designed to support EU DPP requirements.

The CITAQ verification architecture is designed with DPP compliance in mind. Here is how each DPP requirement maps to the CITAQ verification model:

✓
GS1 Digital Link
CITAQ is designed to produce GS1 Digital Link-compatible product identifiers, so your product record can be accessible via a standardized digital link aligned with the EU's digital accessibility requirement.
✓
Cryptographic verifiability
CITAQ's verification model is designed to sign records as W3C Verifiable Credentials using Ed25519 or ECDSA cryptography, so any compliant regulatory system can verify a record's authenticity independently.
✓
Continuous update
CITAQ's revocation model (W3C Status List 2021) is designed to propagate record changes promptly. Expired certifications, revoked credentials, and evidence updates are designed to propagate automatically.
✓
Sector-specific profiles
CITAQ's planned battery profile is designed to cover the required DPP fields for the battery mandate. Material composition, charge cycle data, safety certifications, and recyclability scores are structured as machine-readable evidence records.

Status: On the CITAQ roadmap — designed into the verification architecture ahead of the 2027 mandates.

Related Mandate

GS1 Sunrise 2027 arrives one month before the DPP battery mandate.

By January 2027, all retail barcodes globally must be GS1 Digital Links — not just traditional barcodes. This affects every product with a barcode, not just EU-sold products.

A GS1 Digital Link encodes more than a product identifier. It encodes a URL that links to machine-readable product data. The intent is that any scanner — phone, retail system, AI agent — can access structured product information from the barcode.

CITAQ is designed to produce GS1 Digital Link-compatible records as part of verification output, so your verified product record can be accessible via the Digital Link format.

Two mandates. One infrastructure.

January 2027 (GS1) and February 2027 (EU DPP batteries) arrive within 30 days of each other. CITAQ is designed to support both.
