EAC Certificate of Conformity (TR CU CoC) Complete Guide
1. Basic Definition & Legal Status
EAC CoC = Certificate of Conformity to TR CU Technical Regulations
It is the mandatory third-party certification document for high-risk goods entering the 5 EAEU countries (Russia, Belarus, Kazakhstan, Armenia, Kyrgyzstan).
Issued only by Rosaccreditation-accredited EAEU certification bodies on anti-counterfeit official security paper with holograms, unique serial number and official seal.
EAC CoC sample document
Legal priority: If your product falls under any TR CU regulation, CoC fully replaces national GOST-R / GOST-K / GOST-BY; national single-country GOST documents are rejected by customs.
Validity scope: One certificate covers free circulation across all 5 EAEU member states.
Core rule: CoC is mandatory for high-risk products; DoC cannot substitute CoC.
