Based on comprehensive analysis of the search results, the statement "Eurasian Union EAC Certification (EAC Certification) is the full name of Eurasian Economic Union Technical Certification (CU TR Certification)" requires clarification and contextual refinement. Below is a detailed breakdown:
📌 1. Terminology Relationship
EAC Certification (Eurasian Conformity):
The official name for the certification mark ("EAC" logo) used across the Eurasian Economic Union (EAEU) to indicate compliance with unified technical regulations.
CU-TR/TR CU Certification (Customs Union Technical Regulations):
Refers to the legislative framework governing product safety standards within the EAEU.
Key Insight:
EAC Certification is the outcome (the certificate/mark), while CU-TR/TR CU represents the technical regulations underpinning the certification. They are interdependent but not synonymous.
⏳ 2. Historical Evolution
2010–2015:
The system originated as "CU-TR Certification" under the Customs Union of Russia, Belarus, and Kazakhstan, replacing national GOST certifications (e.g., GOST-R, GOST-K).
Post-2015:
After the Customs Union expanded into the Eurasian Economic Union (EAEU) (adding Armenia and Kyrgyzstan), the certification was rebranded as EAC Certification, though regulations retained "TR CU" prefixes (e.g., TR CU 004/2011).
Current Status:
"TR EAEU" is gradually replacing "TR CU" in new regulations, but "EAC Certification" remains the consistent term for the compliance process.
📋 3. Core Components of EAC Certification
Component    Description    Source
EAC Certificate of Conformity (CoC)    Issued by accredited bodies; requires product testing + factory audits; for high-risk products (e.g., machinery, elevators).    
EAC Declaration of Conformity (DoC)    Self-declared by manufacturers; based on technical documentation; for low-risk products (e.g., packaging, textiles).    
Validity Period    1–5 years (multi-batch) or single-batch (tied to one contract).    
Applicant Requirement    Must be an EAEU-registered legal entity (non-EAEU firms need a local representative).    
⚙️ 4. Certification Process
1.Product Classification: Match products to applicable TR CU/EAEU regulations (e.g., TR CU 020 for EMC).
2.Testing: Samples evaluated in EAEU-accredited labs.
3.Factory Audit (CoC only): Production assessment for multi-year certificates.
4.Documentation: Technical files, ISO 9001 certificates, and test reports.
5.EAC Marking: Apply the EAC logo (min. 5mm) to products/packaging.
🌐 5. Scope and Significance
Coverage: Mandatory for 61 product categories, including electronics, machinery, toys, food, and vehicles.
Market Access: Valid in all EAEU member states (Russia, Belarus, Kazakhstan, Armenia, Kyrgyzstan).
Legal Implication: Non-compliance risks fines, product seizures, or market bans.
💡 Strategic Recommendations
For Exporters:
Confirm whether your product requires CoC or DoC using the TR CU/EAEU annexes.
Partner with EAEU-based representatives to handle certification logistics.
Documentation Tip:
Ensure technical files include risk assessments, design specs, and compliance matrices.
Conclusion
While "EAC Certification" is the umbrella term for compliance marking in the EAEU, CU-TR/TR CU denotes the technical regulations forming its basis. The system eliminates redundant national certifications, enabling "one certificate, five markets". Exporters must align products with specific TR CU/EAEU directives and adhere to CoC/DoC protocols for seamless market entry.

⏱️ Timeline Insight: From GOST-R (pre-2010) → CU-TR (2010–2015) → EAC (post-2015), this evolution reflects deepening regional integration.
