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

2. Geographic Validity (Biggest Difference)
EAC Certification    GOST-R Certification
Valid in all 5 EAEU countries: Russia, Belarus, Kazakhstan, Armenia, Kyrgyzstan    Valid only inside Russian Federation
One certificate covers whole union free circulation; no extra certification for other EAEU states    If you sell to Kazakhstan/Belarus, you still need separate GOST-K / GOST-BY
Uniform cross-border recognition at all EAEU customs ports    Not accepted at customs of other EAEU members
3. Applicable Product Scope
EAC (Covers ~90% mainstream export goods)
All products listed under unified TR CU regulations:
Low-voltage electrical (TR CU 004/2011)
EMC electromagnetic compatibility (TR CU 020/2011)
General machinery safety (TR CU 010/2011)
Explosion-proof Ex equipment (TR CU 012/2011)
Toys, children’s products, pressure vessels, lifts, vehicles, cosmetics, food packaging, furniture, textiles etc.
Mandatory GOST-R (Only residual non-TR CU goods)
Products with no EAEU unified technical regulations:
High-voltage power equipment, transformers, metering measuring instruments
Special industrial chemicals, paints, fertilizers
Rolled steel, metal profiles, special construction materials
Certain batteries, ceramic tableware, telecom radio terminals
Voluntary GOST-R: All other goods (only for tender/marketing, not customs mandatory)
4. Document Types & Maximum Validity Term
EAC
Two documents: EAC Certificate (CoC) / EAC Declaration (DoC)
Serial production certificate maximum: 5 years
Batch certificate: Single shipment only
GOST-R
Two documents: GOST-R Certificate / GOST-R Declaration
Serial production certificate maximum: 3 years (shorter than EAC)
Batch certificate: Single shipment only
5. Marking Mandatory Rules (2026 Updated)
EAC
EAC logo minimum height ≥5mm
Mandatory QR code linked to unified EAEU FGIS registry; missing QR leads to cargo detention
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
Quick Summary Comparison Table

Main Product Range    Machinery, electronics, toys, consumer goods    High-voltage meters, special chemicals, metal materials
Cross-EAEU Sales    One certificate for all markets    Need separate national cert per country
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)
