ETSI EN 303 645 was published in 2020 as the European baseline for consumer IoT security. The UK Product Security and Telecommunications Infrastructure Act 2022 made parts of it mandatory in the UK. In the EU, the CRA supersedes and expands upon ETSI EN 303 645 for products with digital elements. The CRA's Annex I requirements are broader (they cover all products with digital elements, not just consumer IoT), deeper (they require an SBOM, a CVD policy, and ENISA notification), and enforceable (€15M / 2.5% under Article 64). If the European Commission publishes harmonised standards for the CRA that reference ETSI EN 303 645, conformity with the standard could create a presumption of conformity with the overlapping Annex I requirements. But the Annex VII documentation, the Declaration of Conformity, and the Article 14 notification template are CRA-specific and must be produced separately. CRACheck produces them. €149. 15–25 minutes.

ETSI EN 303 645 conformity strengthens your Annex VII file. It does not replace it.
ETSI EN 303 645 is a voluntary standard with 13 baseline provisions for consumer IoT. The CRA is a mandatory EU regulation with 21 requirements, mandatory documentation, and enforceable penalties. Conformity with the standard is supporting evidence, not compliance with the regulation.
The CRA requires: SBOM in machine-readable format (Part II point 1), coordinated vulnerability disclosure policy (Part II point 5), ENISA notification within 24 hours (Article 14), and free security updates throughout the support period (Part II point 8). ETSI EN 303 645 Provisions 5.2 and 5.3 partially address vulnerability disclosure and software updates, but not at the specificity or enforcement level of the CRA.
The UK PSTI Act references ETSI EN 303 645 for certain requirements. The EU CRA is a separate regulation with its own documentation requirements. UK market compliance does not produce EU CRA documentation. If you sell in both markets, you need both compliance sets.
CRACheck generates CRA documentation, referencing ETSI EN 303 645 where applicable. Covers all CRA-specific requirements.
