Based on the search results, the EAC Declaration process is significantly faster than the EAC Certificate process under TR TS 004/2011 (CU TR 004/2011). Here's a detailed comparison:
⏱️ Time Consumption Comparison
Aspect    EAC Certificate (CU-TR Certificate)    EAC Declaration (CU-TR Declaration)
Average Processing Time    1–5 months
(Due to mandatory testing + factory audits + annual surveillance)     1–3 weeks
(Document review only; no testing/audits required) 
Key Time-Consuming Steps    - Lab testing (weeks)
- Factory audits (onsite/video)
- Annual surveillance audits     - Technical file preparation (days)
- Certification body review (days) 
Validity Period    Up to 5 years (requires ongoing audits)     Up to 5 years (no audits, but dependent on contract/batches) 
Critical Delays    - Sample logistics to EAEU labs
- Audit scheduling
- Non-compliance remediation     - Incomplete documentation
- Applicant responsiveness 
🔍 Key Factors Affecting Timelines
1.Testing Requirements
Certificate: Mandatory lab testing in EAEU-accredited facilities (e.g., cables, household appliances). Complex products may require weeks of testing .
Declaration: Self-declaration based on existing test reports or minimal checks. No lab involvement unless disputed .
2.Factory Audits
Certificate: Batch production certificates require initial and annual audits (onsite or remote), adding 1–2 months .
Declaration: No audits (except Scheme 6D with ISO 9001) .
3.Documentation Complexity
Declaration: Requires fewer documents (e.g., technical specs, supplier contracts) but only EAEU-registered entities can apply .
Certificate: Extensive documentation (test protocols, quality management reports) but open to foreign manufacturers .
4.Post-Certification
Certificate: Annual surveillance audits extend administrative burden .
Declaration: Amendments require full re-issuance if errors occur .
💎 Summary
For urgent needs: Choose EAC Declaration (1–3 weeks) if your product is low-risk (e.g., non-critical industrial components) and you have an EAEU-based legal entity .
For long-term batches: Opt for EAC Certificate (1–5 months) for high-risk products (e.g., cables, power tools), accepting delays for broader market access .
⚠️ Note: Product type dictates the path. High-risk items (e.g., household appliances) must undergo Certificate procedures , while Declaration-eligible products can optionally pursue Certification . Always confirm product classification with an accredited body.
