The question “How long is CE certification valid?” gets mixed answers – “permanent” vs. “3 years”. Both can be partially correct. CE validity is a combination of certificate, technical file, production consistency, and regulatory updates – each needs separate handling.

1. What “Validity” Really Means

Self‑declaration directives (EMC, LVD, RoHS for most consumer products): no expiry date – as long as the product is unchanged, standards are not repealed, and documents are in order, the DoC remains valid. But note: a new edition of a harmonised standard, or a new directive replacing the old one, requires a new DoC – even if the product hasn’t changed.

NB‑issued directives (RED high‑risk, medical devices, pressure equipment): the EU‑Type Examination Certificate has a statutory 5‑year maximum – it must be renewed before expiry.

1.1 Module D/D2 – Annual Factory Audits

If your product uses Module D/D2 (production quality), the NB must perform annual on‑site surveillance – it’s mandatory. For Module B (type only), there is no annual reporting, but NBs use random spot checks.

  2. EMC Directive

Self‑declaration for most – no expiry. But industrial/medical power supplies may use NB type‑examination (5‑year). Test reports follow the harmonised standard version – when the transition period ends, products must fully comply with the new edition, not just a gap analysis.

2.1 Low Voltage Directive (LVD)

Same logic – consumer self‑declaration, industrial/medical NB 5‑year certificates.

2.2 RED Directive

Most products self‑declare; only Category 1 and 2 devices require NB (note: RED uses “Category 1/2”, not “Class 3” – that’s FCC terminology). NB certificates expire after 5 years – no exceptions.

2.3 RoHS

Self‑declaration – no expiry. Correction: DINP, DIDP, DNOP restrictions became mandatory in July 2024, not 2026. Existing stock is unaffected, but new production must comply.

2.4 EN18031 Cybersecurity

EN18031 is a harmonised standard under RED, not a standalone regulation. Ordinary aftermarket wireless devices use SDoC – no annual security report obligation. Only high‑risk financial‑payment devices require NB 5‑year certificates. There is no statutory “annual cybersecurity reassessment” for all connected devices – that’s a self‑governance practice.

  3. Standard Version Updates

Standards are revised periodically. During the transition period, both old and new are acceptable. After the transition ends, new products must fully meet the new version.

3.1 Gap Analysis – Not Enough on Its Own

If new requirements are not met, you must retest – a gap analysis alone won’t satisfy customs or market surveillance. Full compliance is required by the end of transition.

3.2 Technical Files Must Stay Current

Keep technical files aligned with the actual product. If you change your EU Representative (EC‑REP), you must re‑issue the entire technical file and DoC with the new representative – changing only the label is insufficient.

  4. Production Conformity (COP)

CE is not just about the sample – batch production must match. For NB‑certified products, NBs use random factory COP audits. Module D/D2 has mandatory annual surveillance; Module B does not.

4.1 Critical Component Changes

If you change a key component to the same manufacturer and same part number, internal documentation is enough. But a “same specification” part from a different manufacturer is considered a significant change – must be assessed or retested.

4.2 Annual Checks – Vary by Module

Module D/D2 – mandatory annual NB on‑site audit. Module B – no statutory annual check, but it’s wise to review documents and standards regularly.

  5. Renewal – Self‑Declaration vs. NB

·Self‑declaration – no renewal; update documents if standards/regulations change.

·NB certificate – must be renewed before the 5‑year expiry; otherwise, it becomes invalid and you cannot ship with CE marking. Renewal involves document review + supplementary testing.

5.1 Changing Notified Bodies

You cannot “transfer” a 5‑year type‑examination certificate to a new NB – you must go through full reassessment. The old technical file can only be used for difference analysis to shorten some test hours – not a direct transfer.

  6. Market Surveillance

EU member states routinely check products on the market – both documents and samples. Serious non‑compliance leads to the Safety Gate alert – EU‑wide ban, forced recall, and fines. It’s not just about customs clearance.

6.1 Customs Inspections

EU customs check CE marking, manufacturer and EC‑REP information. Missing or incorrect info leads to detention. Inspect every batch before shipping.

6.2 EU Representative (EC‑REP)

Non‑EU manufacturers must appoint an EC‑REP. Their details must appear on the product. When changing EC‑REP, re‑issue all technical files and DoC – changing only the label is invalid.
