PassportLab.io is the sovereign infrastructure layer for the EU Digital Product Passport (DPP). We provide the "Trust Layer" that allows Iron, Steel, and Textile brands to transform complex industrial data into cryptographically secure, machine-readable assets. As a JRC Stakeholder-led platform, we bridge the critical gap between "compliance on paper" and the technical interoperability required by the 2027 EU ESPR mandate. While most solutions focus on the physical label, PassportLab.io architected a resilient protocol-built on UNTP v0.6.0 and W3C Verifiable Credentials, to ensure that product data survives the mandatory 10-year audit window. We don't just generate QR codes; we secure your market access through institutional-grade data persistence that resolves at any EU customs check.
