Detailed comparison and analysis of the certification requirements and processes for high-voltage cables in Russia (GOST-R), Kazakhstan (GOST-K), and Kyrgyzstan (GOST-KG):
I. Russian GOST-R Certification
1. Regulatory Basis  
Mandatory certification scope: High-voltage cables with voltages exceeding 1 kV (such as flexible cables for mining, non-fixed installation power cables, etc.) must undergo mandatory GOST-R certification, in accordance with Russian Government Decree No. 2425 (2021) and Decree No. 982 (2009).
Not applicable to EAC certification: High-voltage cables are not within the scope of the Customs Union EAC certification and must undergo GOST-R certification.  
2. Certification Types  
GOST-R Certificate of Conformity (CoC): Requires laboratory testing + factory audit, valid for 1/3/5 years (5-year validity requires annual supervisory audits).
GOST-R Declaration of Conformity (DoC): Applicable to certain fixed-installation cables (e.g., plastic/paper-insulated cables below 35kV), self-declared by a Russian legal entity.  
3. Key Standards  
Non-fixed-installation cables: GOST 24334-202023.
Mining cables: GOST 31945-201223.  
4. Process and Documents  
Process: Application → Document review → Sample testing → Factory inspection (if applicable) → Certificate issuance.  
Documents: Russian application form, ISO 9001 certificate, technical drawings, test reports (e.g., CE/IECEx).
5. Labeling Requirements  
Must affix the GOST-R mark (minimum 5mm) and Russian-language information.  
II. Kazakhstan GOST-K Certification  
1. Regulatory Basis  
Mandatory certification scope: High-voltage cables must comply with GOST-K standards and Eurasian Economic Union technical regulations (e.g., TR CU 004/2011).
Relationship with EAC certification: Some high-voltage cables may require simultaneous application for GOST-K and EAC certification.  
2. Certification Types  
GOST-K Certificate of Conformity (CoC): Valid for 1/3 years, requires factory audit (annual supervision required for 3-year validity).  
Single-batch certificate: Limited to specific contract batches, no factory inspection required.  
3. Key Standards
Refer to Russian GOST standards (e.g., GOST 24334-2020) and Kazakh supplementary requirements.  
4. Process and Documents  
Process: Application → Testing (local laboratory) → Factory inspection (if applicable) → Certificate issuance.  
Documents: Kazakh/Russian technical documents, ISO 9001 certificate, import contract.
5. Labeling Requirements  
Must include the GOST-K mark and Kazakh/Russian language information.  
III. Kyrgyzstan GOST-KG Certification  
1. Regulatory Basis  
Mandatory certification scope: High-voltage cables must comply with GOST-KG standards and Eurasian Economic Union technical regulations (e.g., TR CU 004/2011).  
Relationship with EAC certification: Some products require concurrent application for EAC certification.
2. Certification Types  
GOST-KG Certificate of Conformity (CoC): Requires sample testing + factory audit, valid for 1-5 years.  
GOST-KG Declaration: Some products may be self-declared, but high-voltage cables typically require mandatory certification.  
3. Key Standards  
References IEC 62271 series (high-voltage switchgear) and local standards.  
4. Process and Documents
Process: Application → Testing (mutually recognised laboratory) → Factory inspection (if applicable) → Certificate issuance.  
Documents: Russian/Kyrgyz technical documents, ISO 9001 certificate, CE/GOST-R test reports.  
5. Labelling Requirements  
GOST-KG mark and Russian/Kyrgyz labels must be affixed.

V. Recommendations
Plan Ahead: The certification process for high-voltage cables is lengthy (typically 1–3 months), so sufficient time should be allocated.
Local Agent: All three countries require applications to be submitted through a local legal entity or authorised representative.  
Document Translation: All technical documents must be translated into the local official language.  
Testing Recognition: Existing CE/IECEx/GOST-R test reports can reduce the need for duplicate testing.  
For specific product certification solutions, it is recommended to contact a professional institution (such as Shanghai Jinghe Industrial) for customised services.
