5. Two parallel EAC documents under TR CU framework

1. EAC CoC (Certificate of Conformity): high-risk goods, third-party certification, factory audit (1C), joint liability of notified body + AR

2. EAC DoC (Declaration of Conformity): medium/low-risk goods, self-declared by EAEU AR, no factory audit, AR bears full liability

Important: The applicable TR CU explicitly defines whether CoC or DoC is required. You cannot freely choose between them.

6. Key legal obligations under TR CU

• The full technical dossier (product passport, Russian manual, drawings, test reports, label artwork, authorisation contract) must be preserved for minimum 10 years after certificate expiry or the last batch release

• Product labels and operating documentation must include mandatory information in Russian (English can be added as supplementary)

• Any change in product design, materials, critical components or manufacturing location requires re-assessment against TR CU; old certificate cannot continue to be used

• EAC marking can only be affixed after FGIS registration

• 
  

7. What TR CU / EAC Certificate does NOT cover

• It does not replace separate permits such as SGR state registration, fire licences, RZN medical registration, Kazakhstan GGTN permits

• It only covers the exact product models, manufacturer and TR CU listed in the certificate

• The certificate ≠ EAC mark. EAC is the graphic conformity logo placed on product/packaging.

Quick summary

TR CU are the harmonised mandatory technical safety laws of the Customs Union / EAEU. The EAC Certificate (CoC) is the third-party conformity document that proves high-risk products comply with those TR CU requirements. Once registered in FGIS, it allows customs clearance, cross-EAEU trade and application of the EAC mark.
