# CE Conformity Assessment Modules: A, B, G, H — Which Applies to You?

CE marking doesn't follow a single path. The conformity assessment route — whether you can self-declare or need a Notified Body — depends on which directive applies to your product and what risk level that directive assigns to it. Understanding the module system tells you exactly what evidence you need to gather and whether a third party must be involved.

### Not all CE marking is self-declaration

Most consumer electronics can be CE-marked through self-declaration, but not every product qualifies. Your applicable directive dictates the route, and higher-risk products need a Notified Body involved. Knowing the module system tells you which path your product takes before you build documentation.

### The module framework explained

Decision 768/2008/EC sets the module system. Module A is self-declaration, no Notified Body. Module B needs a Notified Body type examination. Module G verifies each unit. Module H means an audited quality system for higher-risk products.

### How to determine your route

Start with your applicable directive — LVD, RED, EMC, or the Machinery Regulation. Each lists its permitted modules in its Annex. Module A covers most consumer electronics. Medical devices, higher-risk machinery, and pressure equipment need third-party involvement. Confirm your route before building your technical file.
