The honest answer: 8–16 weeks for most electronics hardware, assuming no test failures. With failures, add 4–8 weeks per re-test cycle. The biggest mistake hardware teams make is not starting the CE process until 4 weeks before a planned ship date.

Can be done in parallel with hardware finalisation. 02 Pre-compliance / internal testing 2–4 weeks Running pre-compliance EMC scans and basic safety checks in-house or at a pre-compliance lab to catch design issues before formal testing. Iterating on layout, filtering, or enclosure changes. 03 Lab booking and sample preparation 2–8 weeks (lab lead time) Booking slots at an accredited test laboratory. Lead times vary significantly by lab and time of year — popular labs booking 6–8 weeks ahead is normal. Preparing pre-production samples that meet the lab's requirements takes additional time. 04 Formal accredited testing 1–3 weeks on-site The actual time spent in the test lab. A typical consumer electronics product with Wi-Fi and Bluetooth (RED, LVD) may take 5–10 business days. Complex products with many radio technologies or extensive safety testing take longer. 05 Test report review and failure remediation 1–6 weeks (if failures occur) If any test fails, the product must be redesigned, rebuilt, and retested. This can mean going back in the lab queue. One failed emission limit can add 4–8 weeks to the timeline. 06 Technical file compilation and DoC signing 1–2 weeks Assembling the full technical file, drafting the EU Declaration of Conformity, and having it reviewed and signed by an authorised signatory. ## Common causes of timeline delays * Failing an EMC emissions test — requires hardware changes and re-test * Discovering the wrong harmonised standard was applied — may require additional testing * Lab unavailability or long booking queues — particularly for specialist testing (SAR, battery, ATEX) * Incomplete or incorrect test samples (missing accessories, wrong firmware) * Notified Body review time — for products requiring NB involvement, reviews can take 4–12 weeks * Supply chain issues preventing production of pre-production samples at the right spec ## Frequently asked questions ### What is the fastest possible CE marking timeline? For a simple product (e.g., a mains-powered accessory needing only LVD and EMC) with no pre-compliance issues, 6–10 weeks from test booking to DoC signing is achievable. For radio products under RED, 8–14 weeks is more realistic. These assume no test failures and immediate lab availability. ### Can I speed up CE marking by doing multiple directives simultaneously? Yes — testing for LVD, EMC, and RED can often be scheduled with a single lab visit in a single booking. Testing lab slots are typically booked for the full scope of testing. Using a single lab for all applicable directives avoids the coordination overhead of multiple lab bookings. ### Should I wait until hardware is finalised before booking a lab? No — book your lab slot at least 6–8 weeks before you expect to have test samples ready. Labs fill up, and missing a slot costs more time than booking slightly early. If your hardware is delayed, you can usually reschedule within the same lab booking. ### How much longer does CE marking take with a Notified Body? Notified Body involvement (for Annex IV machinery, medical devices, or certain RED products) adds 4–12 weeks depending on the NB's queue, the complexity of the product, and whether the NB review identifies any issues requiring resolution. **Disclaimer:** Timelines are estimates based on typical experiences. Actual timelines depend on product complexity, lab availability, and design outcomes.
