- China posts a 2025 DPP report that cites IOTA as an SSI example using DIDs.
- The paper urges EU–China mutual recognition and highlights QR-code migration.
China’s Ministry of Commerce has published a 2025 report on Digital Product Passports compiled by the China Academy of Information and Communications Technology, with support from the China National Institute of Standardization.
The document explicitly cites IOTA as an example of self-sovereign identity built on W3C Decentralized Identifiers, framing user-controlled credentials as a design pattern for verifiable data exchange in cross-border trade.
Report names IOTA’s DID-based SSI and ties it to cross-chain identity
The report discusses DID architectures that support cross-chain interoperability and points to IOTA’s SSI stack to illustrate how issuers, holders and verifiers can transact attestations without central directory dependence.
In the Chinese policy context, the example anchors identity and product data to tamper-evident records while allowing companies to keep commercially sensitive data off chain. The reference is presented as a technical case within a broader survey of DPP enabling technologies.
Paper proposes EU–China “mutual recognition” and signals EBSI–Xinghuo alignment
Beijing’s stance in the report is to avoid a one-way “plug-in” to European systems and instead advance a model of mutual recognition for passports and credentials. Language in companion summaries emphasises replacing simple access with two-way acceptance to lower compliance costs for exporters and to protect data sovereignty.
Analysts tracking the publication note that this direction would require interoperability between Europe’s EBSI stack and China’s national blockchain infrastructure, including Xinghuo BIF, rather than a wholesale adoption of either side’s stack.
🚨 IOTA, and only IOTA, is officially recognized in the 2025 policy paper by China’s Ministry of Commerce.
In 2025, China’s Ministry of Commerce released a landmark report on the Digital Product Passport (DPP), authored by the CAICT (China Academy of Information and…

The document also situates identifiers and data carriers in a migration path toward next-generation QR codes, aligning with the GS1-led Global Migration to 2D initiative. GM2D sets a timeline to phase in 2D barcodes as a universal access point to product data, which could host DPP payloads and verification endpoints across jurisdictions.
Battery Pass, Catena-X and CIRPASS are reviewed alongside UN’s UNTP work
Beyond IOTA, the report surveys European industrial pilots that are likely to shape data schemas and governance. These include the Battery Pass consortium’s technical guidance for EU battery passports, the Catena-X automotive network’s data models and demonstrators, and CIRPASS roadmaps for batteries, electronics and textiles.
The paper also references United Nations work under the UN Transparency Protocol, which is defining a protocol layer so that DPP data and conformity claims can move between platforms without mandating a single system.
For China, the policy trajectory described would place DPP as a trade facilitation instrument supported by verifiable credentials and machine-readable labels, with bilateral recognition as the bridge between European and Chinese implementations.
The mention of IOTA’s SSI illustrates one route to decentralised identity under DID standards while leaving room for convergence with existing public infrastructure such as EBSI in the EU and Xinghuo BIF in China.
