Self-declaring conformity means the manufacturer takes full responsibility for showing that a product meets the applicable EU legal requirements and issues the required documentation, while using a notified body means an independent, EU-designated third party performs a formal conformity assessment step required by certain laws. The key difference is whether EU law allows internal control or mandates third-party involvement.
In practice, the right route depends on the product category, the specific EU legislation that applies, and the risk level and assessment module required under EU conformity assessment procedures. Many products can be self-declared, but some CE marking requirements trigger mandatory notified body assessment.
The questions below break down what each route involves, when a notified body is required, and how to choose the right path for EU product compliance.
What is self-declaration of conformity in EU product compliance?
Self-declaration of conformity is an EU conformity assessment approach where the manufacturer evaluates the product against the applicable EU requirements, compiles the technical documentation, and issues the EU Declaration of Conformity when the law requires it. No third party certifies the product, and the manufacturer remains fully accountable for compliance.
Self-declaration is common under CE marking requirements when the applicable legislation permits internal production control. It typically involves identifying which EU rules apply, checking essential requirements, and documenting how the product meets them.
In a self-declaration route, manufacturers usually need to:
- Determine the applicable EU harmonisation legislation and standards for the product
- Perform and document a risk assessment and any required testing
- Compile and maintain technical documentation that supports compliance
- Prepare user information such as instructions and safety information in required languages
- Issue an EU Declaration of Conformity when required by the applicable CE legislation
- Affix the CE marking when the product falls under CE marking requirements and all conditions are met
Self-declaration does not mean no rules apply. It means the manufacturer is the one demonstrating conformity, and market surveillance authorities can request evidence at any time.
What is a notified body and what do they do?
A notified body is an independent conformity assessment organization designated by an EU Member State and notified to the European Commission to perform specific tasks under specific EU laws. They carry out notified body assessment activities such as EU type examination, audits of quality systems, and review of technical documentation when third-party involvement is required.
Notified bodies do not approve every product category. Each notified body has a defined scope, meaning it can only assess certain product types and certain conformity assessment modules under particular directives or regulations.
Depending on the legislation and module, a notified body may:
- Review technical documentation for completeness and compliance
- Test a representative sample or witness testing
- Perform an EU type examination and issue an EU type examination certificate
- Audit production or quality management systems and perform surveillance audits
- Verify ongoing conformity for higher-risk products through periodic checks
Even when a notified body is involved, the manufacturer still holds primary responsibility for EU product compliance and for ensuring the product placed on the market matches the assessed design and controlled production.
When is a notified body required instead of self-declaration?
A notified body is required when the applicable EU harmonisation legislation mandates third-party involvement for the product and the chosen EU conformity assessment procedures include a notified body module. This typically happens for higher-risk products or where the law requires independent verification beyond internal production control to meet CE marking requirements.
The trigger is not preference. It is the specific legal framework for the product. For example, some categories under PPE, medical devices, certain machinery-related functions, gas appliances, pressure equipment, radio equipment in specific scenarios, and other regulated areas can require notified body assessment depending on classification and risk.
To determine whether a notified body is required, work through this sequence:
- Identify all EU laws that apply to the product and its intended use
- Check the conformity assessment modules allowed or required by those laws
- Confirm the product classification or category that drives the module choice
- Verify whether the module includes notified body involvement
Also separate CE compliance from general product safety obligations. The General Product Safety Regulation (EU) 2023/988 (GPSR) sets broad safety obligations for consumer products, but it is not the framework that creates CE marking requirements or a notified body pathway. For many consumer products, GPSR applies alongside, or in the absence of, sector-specific CE legislation.
For online and cross-border sales, the Market Surveillance Regulation (EU) 2019/1020 (MSR) matters because it strengthens enforcement and sets obligations around having an EU-based economic operator for certain regulated products. Under Article 4 MSR, the Responsible Person role is carried out by an economic operator and must inform the manufacturer when it has reason to believe a product presents a risk.
How should you choose between self-declaration and a notified body route?
You should choose self-declaration or a notified body route by following the legally required EU conformity assessment procedures for your product, not by convenience. Start by confirming which EU laws apply and which conformity assessment module they require. If the module includes third-party involvement, notified body assessment is mandatory.
When the law allows self-declaration, the decision becomes about execution quality and risk control. A strong self-declaration file can be more defensible than a weak file that relies on assumptions.
Practical decision checklist for EU conformity assessment procedures
- Product scope: Does the product fall under CE marking requirements, and if so, which directive or regulation applies?
- Classification: Is the product in a category that triggers a notified body module?
- Evidence readiness: Do you have test reports, a clear risk assessment, and complete technical documentation?
- Production control: Can you ensure ongoing conformity across batches and suppliers?
- Market access reality: Are marketplaces or business customers asking for specific certificates that only exist with a notified body module?
Common mistakes that create compliance risk
- Assuming CE marking always requires a notified body, or assuming it never does
- Using standards without confirming they match the exact product configuration and intended use
- Issuing an EU Declaration of Conformity when the product is not actually within CE scope, or missing it when CE law requires it
- Keeping incomplete technical documentation that cannot be produced quickly when authorities request it
- Confusing GPSR obligations with CE marking requirements and sector-specific conformity assessment rules
How EARP helps with self-declaration and notified body readiness
We help non-EU manufacturers and sellers stay compliant by making the self-declaration of conformity route and notified body assessment preparation practical, structured, and audit-ready for EU product compliance. Our work focuses on documentation control, EU-based representation, and fast response readiness when authorities or marketplaces ask for proof.
- Clarify which CE marking requirements and EU conformity assessment procedures apply to your product
- Verify the presence and completeness of required product safety documentation and technical files
- Store documentation in the EU and make it available to authorities upon request through established processes
- Support GPSR Responsible Person coverage where required and align roles with MSR Article 4 obligations
- Coordinate readiness for notified body engagement when the law requires third-party assessment
To get started, review our EU compliance services and then contact our team to discuss your product and the correct conformity route.
