EAC vs GOST-R Certification – Full Detailed Differences Core Rule First (Critical Priority) TR CU / EAC legal status overrides GOST-R entirely: If your product falls under any EAEU TR CU technical regulation → EAC (CU-TR) is mandatory, GOST-R will be rejected by Russian customs Only goods with NO applicable TR CU rules require mandatory GOST-R for Russia import/sale The two systems cannot replace each other; they apply to separate product ranges 1. Basic Definition & Governing Body EAC (CU-TR / TR CU Certification) Full name: Eurasian Conformity Mark Certification Legal base: Unified TR CU Technical Regulations of the Eurasian Economic Union (EAEU) Regulator: Eurasian Economic Commission (EEC) + national Rosaccreditation bodies Purpose: Unified cross-border market access for all 5 EAEU member states Mark: Square unified EAC logo GOST-R (Russian National Certification) Full name: Государственный стандарт России (Russian State Standard) Legal base: Russian national GOST standards + Government Decree No.2425 Regulator: Rosstandart (Russian Federal Agency for Technical Regulation and Metrology) Purpose: National compliance only for Russia domestic territory Mark: Circular PCT / RST national mark
Standardized logo design enforced across all 5 countries
GOST-R
Circular PCT mark minimum height ≥8mm
QR trace code not strictly enforced by Russian customs
National Russian-only marking standard
6. Technical Standards & Test Acceptance
EAC
Harmonized unified EAEU cross-border safety standards (aligned with EU CE logic)
For CoC: Tests must be done in Rosaccreditation-accredited labs (any EAEU country lab accepted, though Russia labs preferred 2026)
GOST-R
Pure Russian national GOST standards, stricter local technical requirements for special industrial goods
Mandatory tests must be completed in Russian domestic accredited labs only; test reports from Kazakhstan/Belarus labs invalid
7. Business Cost & Application Cycle
EAC
Higher overall cost (unified union standard, more comprehensive testing)
CoC lead time: 4–12 weeks (testing + factory audit)
DoC lead time: 7–15 working days
GOST-R
Lower cost than EAC CoC
GOST-R Certificate lead time: 3–8 weeks
GOST-R Declaration lead time: 5–10 working days
8. Legal Liability & Authorized Representative
EAC
Must appoint any EAEU legal entity (Russia/Kazakhstan/Belarus etc.) as authorized rep
CoC liability shared by cert body, local rep & importer
DoC full liability borne by EAEU declarant
GOST-R
Only a Russian registered company can be authorized representative; Kazakhstan/Belarus legal entities cannot hold GOST-R documents
Full national legal liability falls on Russian local applicant/importer
9. Customs Compliance Consequences
EAC
Valid EAC document clears customs in all 5 union states
If product belongs to TR CU scope, customs fully reject GOST-R papers
GOST-R
Only works for Russia border clearance
If your product has a TR CU regulation, holding GOST-R cannot avoid cargo seizure, fines or return shipment

Simple Decision Guide for You
Export to multiple EAEU countries (Russia + Kazakhstan/Belarus): Apply EAC
Only sell to Russia, and your product is machinery, low-voltage home appliances, toys: Apply EAC
Only sell to Russia, product is high-voltage meters, industrial steel, special paint with no TR CU rules: Apply mandatory GOST-R
All products can apply Voluntary GOST-R for bidding, local distributor trust (but cannot replace mandatory EAC)
