Conformity Assessments Explained

Before placing a product on the EU market, it must undergo a conformity assessment to verify it meets CRA requirements.

Module A: Self-Assessment (The Default)

Applies to 90% of software products. You (the manufacturer) perform risk assessments, generate SBOMs, and maintain technical documentation internally. No external auditor is hired. You issue your own Declaration of Conformity.

Module B+C / Module H: Notified Body Audits

Applies to 'Important' (Class I/II) or 'Critical' products (e.g., hypervisors, HSMs, identity management systems). For these, you must hire a third-party Notified Body approved by an EU member state to formally audit your code, processes, and architecture before releasing the product.

Cost Implications

Module A essentially costs engineering time. Notified body audits can cost between €20,000 and €100,000+ per product lifecycle.
