The Eurasian Economic Union EAC Certificate of Conformity (EAC COC) is an important certification in the product certification system of the Eurasian Economic Union (EAEU). Here is a detailed introduction:
1. Definition and Purpose
The EAC COC is an official certificate issued by a certification body recognized by the EAEU. It is a form of certificate in the mandatory certification system of the EAEU, which is a unified certification system upgraded from the Customs Union Technical Regulations Certification in 2015. It is used to prove that products meet the relevant technical regulations and standards of the EAEU, and is a necessary condition for products to enter the EAEU market for sale .

2. Applicable Product Scope
Mandatory Certification Products: Products subject to the technical regulations of the Customs Union must be accompanied by a Single Certificate of Conformity with a single sign of circulation of EAC products. The specific product scope is determined by the relevant technical regulations. For example, in the territory of Kazakhstan, it is subject to the national List of products and services subject to mandatory certification (Decree of the Government of the Republic of Kazakhstan dated April 20, 2005 No.367); in the territory of the Customs Union, it is subject to the unified list of products subject to mandatory conformity assessment and the issuance of a uniform form documents (Decision of the Commission of the Customs Union dated April 7, 2011 No. 620). Common products include machinery and equipment, elevators, explosion - proof products, wheeled vehicles, personal protective equipment, food and food - related products, medical devices, etc.
Products in the Unified List: Products included in the Unified List may also be accompanied by a Single Certificate of Conformity, but there may not be a single sign on these documents .

3. Characteristics
Mandatory: For products subject to the technical regulations of the EAEU, obtaining the EAC COC certificate is a mandatory requirement to enter the EAEU market and sell and use the products .
Multi - national validity: The EAC COC certificate has the same legal effect in the five member states of the EAEU (Russia, Belarus, Kazakhstan, Armenia, and Kyrgyzstan). There is no need to apply separately in each country .
Variable validity period: The validity period of the EAC COC certificate is determined by the product type and the regulations of the certification body, generally ranging from 1 to 5 years. During the validity period, the product can circulate freely in the EAEU market .
4. Certification Process
Project application: Enterprises submit project applications to the certification body, including product information and relevant materials .
Document preparation: Enterprises prepare detailed product technical descriptions, test reports, ISO 9001 certificates (if applicable), Russian - language instructions, etc. according to the requirements of the certification body .
Product testing: The product needs to be tested in accordance with the requirements of the EAEU technical regulations to verify its compliance. Testing is usually carried out in an EAEU - recognized laboratory .
Factory audit (if applicable): The certification body may conduct an on - site audit of the production factory to ensure that the production process meets the requirements of the EAEU. For high - risk products, a factory audit is usually required .
Report preparation: The certification body compiles a certification report based on the test results and the factory audit situation .
Certificate issuance: After the certification body's review and approval, the EAC COC certificate is issued to the enterprise .
5. Certificate Features
EAC mark: Products with the EAC COC certificate must be marked with the EAC mark (a triangle composed of the letters "E", "A", and "C") on the product, packaging, or label. The height of the mark should not be less than 5 mm .
Certificate format: The EAC certificate is printed on an official certificate paper form, which has multiple anti - counterfeiting elements and is authenticated by the signature and seal of the recognized institution .
6. Example of Product Testing Standards
For different products, the specific testing standards are different. Taking medical devices as an example, if the product is a medical electrical device, it needs to comply with TR CU 004/2011 "On Safety of Low - Voltage Equipment", and the testing may include insulation strength, grounding protection, and leakage protection tests. For other products, corresponding technical regulations should be referred to for specific testing requirements .
7. Differences from other certifications
Compared with EAC DOC: EAC DOC is a self - declaration by the applicant, suitable for low - risk products, and only requires technical document review without factory audits. EAC COC, on the other hand, is a mandatory certification for high - risk products, usually requiring factory audits and product testing .
Compared with TR CU certification: TR CU certification is an earlier term. After the EAEU was established, the certification system was gradually unified under the EAC framework. The essence is the same, but the terminology and some detailed regulations have been updated .
8. Labeling requirements
Products with the EAC COC certificate must be marked with the EAC mark on the product and/or packaging. The EAC mark is composed of the letters "E", "A", and "C" in an equilateral triangle. The color of the mark should be chosen according to the color of the product label, and the minimum size of the basic dimension should not be less than 5 mm .
9. Annual review requirements
For the EAC COC certificate, in some cases, an annual review is required to ensure that the product continues to meet the relevant technical regulations. The specific review requirements are determined by the certification body according to the product characteristics and the certification scheme .
