How do I know whether a product directive requires a notified body or allows self-declaration?

A product directive requires a notified body when the law assigns your product’s risk category or design to a third party conformity assessment route, rather than allowing the manufacturer to self-assess. You can tell by checking the directive or regulation’s conformity assessment options and your product’s classification, then matching them to the correct module.

In practice, the deciding factors are the product’s intended use, hazard level, and any category lists or annexes that trigger notified body involvement. If you sell into the European Union in 2026, marketplaces and authorities increasingly expect you to provide evidence of the correct route, not just apply a CE mark.

The questions below explain what drives the requirement, how modules work, which laws commonly involve notified bodies, and what changes in your documentation when a notified body participates.

What determines whether a notified body is required?

A notified body is required when the applicable EU product law does not permit full manufacturer self-assessment for your specific product category and instead mandates third party involvement for type examination, quality system assessment, or product verification. The trigger is not the CE mark itself, but the legal conformity assessment route tied to your product’s classification and risk profile.

Start with the exact legislation that applies to your product, then identify the clause or annex that assigns your product to a category. Many EU laws use annexes to define higher risk groups, for example, certain machinery functions, specific pressure equipment ranges, or particular radio features. If your product falls into one of those groups, the law typically points you to modules that include a notified body.

Key determinants to check before you decide you can use CE marking self-declaration include:

Product scope and intended use as defined by the law, not marketing language
Classification rules such as categories, classes, or equipment groups in annexes
Risk level implied by the category, for example higher energy, pressure, lifting, or safety functions
Whether harmonized standards are fully applied because some laws allow simpler routes when standards cover all essential requirements
Whether you are using a novel design where standards do not fully address the risks, which can push you toward third party assessment depending on the law

When you see language like “EU type examination,” “unit verification,” or “assessment of the quality system,” you are usually in notified body involvement territory. When you see “internal production control,” you are usually in self-declaration territory, provided you meet the conditions.

How do conformity assessment modules show if self-declaration is allowed?

Conformity assessment modules are standardized building blocks in EU product law that specify who does what to prove compliance. If the module is “internal production control” only, CE marking self-declaration is typically allowed because the manufacturer performs the assessment and compiles the technical documentation. If the module includes type examination, verification, or quality system approval, a notified body participates.

Modules appear in many directives and regulations as named options, often with letter designations. While the exact menu varies by law, the logic stays consistent: modules that rely solely on manufacturer controls support self-declaration, and modules that add independent review require a notified body.

Use this practical reading method:

Find the conformity assessment section in the applicable law and note the allowed modules for your product category.
Identify the “who” in each module description. If it says a notified body “examines,” “assesses,” “approves,” or “certifies,” self-declaration is not the full route.
Check the conditions such as full application of harmonized standards or limits on product type.
Confirm the output such as an EU type examination certificate or quality system certificate, which signals notified body involvement.

A common mistake is assuming that using harmonized standards always eliminates the need for a notified body. In some laws, standards help you meet essential requirements, but the law still requires third party assessment for higher risk categories.

Which common EU product laws require a notified body in some cases?

Several major CE marking laws allow both self-declaration and notified body routes depending on product category, safety function, or technical parameters. The most common examples include the Machinery Regulation, Pressure Equipment Directive, Radio Equipment Directive, Personal Protective Equipment Regulation, and Medical Devices Regulation. In each case, annex-based classification determines notified body involvement.

Here are typical patterns you will see across common frameworks:

Machinery rules often require third party assessment for certain high risk machinery or safety components listed in annexes, while many standard machines can follow internal production control.
Pressure equipment classification depends on pressure, volume, fluid group, and equipment type. Higher categories generally require a notified body for design examination and or production surveillance.
Radio equipment can allow self-declaration when harmonized standards fully cover the essential requirements, but may require third party involvement when standards are not fully applied or do not exist for key aspects.
Personal protective equipment commonly requires a notified body for higher risk categories, especially where failure could cause serious harm, with ongoing surveillance elements for certain categories.
Medical devices frequently require notified body assessment for most classes beyond the lowest risk, with detailed quality management and technical documentation review.

Separately from CE marking laws, the General Product Safety Regulation (EU) 2023/988 (GPSR) applies broadly to consumer products and focuses on general safety obligations, traceability, and market surveillance cooperation. GPSR does not create a CE marking route by itself, but it can apply alongside sector laws that do.

Also note that the Market Surveillance Regulation (EU) 2019/1020 (MSR) strengthens enforcement and requires certain products to have an EU-based economic operator for compliance tasks. Under Article 4 MSR, the responsible person role is held by an economic operator, and that economic operator must, among other duties, inform the manufacturer if it has reason to believe a product presents a risk.

What documentation and markings change when a notified body is involved?

When a notified body is involved, your compliance file usually expands to include the notified body’s certificate output and evidence of ongoing surveillance where required, and your CE marking may need the notified body identification number next to it. Your EU Declaration of Conformity still lists the applicable legislation and standards, but it also references the notified body and the certificate where relevant.

At a practical level, expect changes in four areas:

Technical documentation often needs more formal structure, with clearer design rationale, risk assessment, test evidence, and traceability to essential requirements because a third party will review it.
Certificates and reports such as EU type examination certificates, quality system approvals, or verification reports become controlled documents you must keep current.
CE marking presentation may require adding the notified body number, but only when the notified body participates in the production control phase as defined by the applicable module.
Ongoing obligations can include audits, periodic assessments, or production surveillance, depending on the module and product law.

Even when self-declaration is allowed, you still need a defensible technical file and a correctly completed EU Declaration of Conformity for CE-marked products. If authorities request information, you must be able to provide it quickly and consistently, especially when a product safety accident or market surveillance check triggers scrutiny.
