CE Mark Declaration of Conformity (DoC) Software

The Declaration of Conformity (DoC) is the most critical compliance document in the European Union. By drawing up and signing the DoC, a manufacturer legally assumes full responsibility for a product's compliance with all applicable EU laws—from the Low Voltage Directive (LVD) and Electromagnetic Compatibility (EMC) to RoHS restrictions and the Machinery Directive. Without a valid, properly formatted DoC, the CE mark cannot be legally affixed, and the product cannot pass through EU customs.

While drafting a DoC seems like a simple paperwork exercise, maintaining compliance across a deep product catalog over years is incredibly difficult. Harmonized EN standards are frequently updated, withdrawn, or superseded. If a manufacturer is relying on a static PDF drafted three years ago, the DoC may reference a standard that is no longer valid, rendering the current production run non-compliant and liable for market recall.

Sustalium modernizes the CE Marking process. Instead of managing hundreds of disconnected Word documents, product teams build dynamic DoC profiles. You select the applicable directives and the platform helps organize the corresponding harmonized standards. The signed Declaration is intrinsically linked to your secure Technical Construction File (TCF)—meaning if market surveillance authorities request proof, the test reports backing up your claims are immediately accessible. When standards update or a product undergoes a technical revision, Sustalium versions the DoC, ensuring you always have a historical record of what was compliant on the exact date of manufacture.
