Based on the search results, the choice between EAC Certificate (CoC) and EAC Declaration (DoC) under TR CU 032/2013 (also known as TR TS 032/2013) depends on risk classification, product parameters, and applicant eligibility. Here's a structured comparison: ⚖️ 1. Core Selection Criteria Factor EAC Certificate (CoC) EAC Declaration (DoC) Risk Category Mandatory for Class 3-4 high-risk equipment: - Pressure vessels >0.001 m³ & >0.05 MPa - Gas pipelines >DN 25 mm - Boilers (>110°C or >0.05 MPa steam) For Class 1-2 lower-risk equipment: - Liquid pipelines ≤DN 25 mm - Valves for non-hazardous media (DN ≤32 mm) Applicant Requirements Open to foreign manufacturers; issued by EAEU-accredited bodies Only EAEU-registered entities (local importer/distributor) Validity Period Up to 5 years (with annual audits for batch production) Up to 5 years (no audits, tied to batches/contracts)

⚖️ 1. Core Selection Criteria
Factor EAC Certificate (CoC) EAC Declaration (DoC)
Risk Category Mandatory for Class 3-4 high-risk equipment:
- Pressure vessels >0.001 m³ & >0.05 MPa
- Gas pipelines >DN 25 mm
- Boilers (>110°C or >0.05 MPa steam) For Class 1-2 lower-risk equipment:
- Liquid pipelines ≤DN 25 mm
- Valves for non-hazardous media (DN ≤32 mm)
Applicant Requirements Open to foreign manufacturers; issued by EAEU-accredited bodies Only EAEU-registered entities (local importer/distributor)
Validity Period Up to 5 years (with annual audits for batch production) Up to 5 years (no audits, tied to batches/contracts)
⚙️ 2. Product-Specific Requirements
Requiring EAC Certificate (CoC):
Pressure vessels: Volume >0.001 m³ & working pressure >0.05 MPa .
Gas pipelines/valves: Nominal diameter >25 mm for hazardous media (flammable/toxic) .
Boilers: Steam pressure >0.05 MPa or water temperature >110°C .
Safety devices: Valves >DN 32 mm for non-hazardous liquids .
Requiring EAC Declaration (DoC):
Low-pressure liquid pipelines: DN ≤25 mm .
Non-critical valves: DN ≤32 mm for non-hazardous gases .
Exclusions: Medical devices, nuclear equipment, aerosol dispensers .
📋 3. Certification Procedures
For EAC Certificate (CoC):
Steps:
1.Submit technical documents (safety justification in Russian, design drawings) .
2.Laboratory testing (e.g., 1.5x hydraulic pressure test, NDT) .
3.Mandatory factory audit (e.g., Scheme 1C/7C) for welding/QMS compliance .
4.Annual surveillance audits .
For EAC Declaration (DoC):
Steps:
1.Compile technical file (self-prepared test reports, technical passport) .
2.No factory audit (except Scheme 6D with ISO 9001) .
3.Register in EAEU database via accredited body .
⚠️ 4. Critical Compliance Requirements
Design & Manufacturing:
Safety justification in Russian, GOST-compliant strength calculations .
Welding must follow GOST R ISO 3834 with 100% NDT .
Documentation:
Technical passport & manuals in Russian/EAEU languages .
Material certificates (e.g., GOST standards) .
EAC Marking:
Mandatory on products (min. 5 mm height) .
⏱️ 5. Timeline & Cost Comparison
Aspect EAC Certificate (CoC) EAC Declaration (DoC)
Processing Time 2–5 months (due to audits/tests) 1–3 weeks (document review)
Cost Drivers Lab tests, factory audits, annual inspections Minimal fees (self-declaration)
💎 Summary & Recommendations
Opt for EAC Certificate (CoC) if:
Handling high-risk equipment (e.g., gas boilers, large pressure vessels).
Foreign manufacturers needing direct certification .
Choose EAC Declaration (DoC) if:
