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.
2. Key Differences: EAC CoC vs EAC DoC
Comparison Item    EAC CoC (Certificate of Conformity)    EAC DoC (Declaration of Conformity)
Issuing Body    Accredited independent third-party cert body    Self-declared by local EAEU importer/authorized rep
Mandatory Lab Test    ✅ Must test samples in Rosaccreditation-accredited EAEU labs (2026 Russia requires Russian labs for clearance)    ❌ Manufacturer internal test reports acceptable
Factory Audit    ✅ Required for serial production (1C/2C schemes) + annual surveillance audit    ❌ No factory audit at all
Document Form    Special security anti-counterfeit paper    Plain A4 white paper, only registry number valid
Liability Sharing    Joint liability: Cert body + EAEU authorized rep    100% full liability borne solely by local declarant
Processing Time    4–12 weeks (sample test + audit + file review)    7–15 working days (document filing only)
Max Validity    5 years (serial); single batch only    5 years (serial); single batch only
Applicable Goods    High-risk (machinery, Ex-proof, lifts, toys, medical devices)    Low/medium-risk consumer goods
3. Mandatory Product List Requiring EAC CoC
All below products are legally forbidden to use DoC; only CoC is permitted:
Explosion-proof equipment (TR CU 012/2011) – mining, oil/gas Ex electrical, Ex pumps, Ex lighting
Lifts, escalators & safety components (TR CU 011/2011)
All toys & children’s play equipment (TR CU 008/2011)
Infant articles: strollers, child car seats, baby bottles, pacifiers (TR CU 007/2011)
Pressure vessels, boilers, gas cylinders (TR CU 032/2013)
Industrial heavy machinery: excavators, cranes, forklifts, CNC machines, welding equipment (TR CU 010/2011)
Fire-fighting equipment: extinguishers, fire alarms, fire doors (TR CU 043/2017)
Category 3 high-risk PPE: gas masks, fall protection harnesses, chemical protective suits (TR CU 019/2011)
Complete vehicles + core safety auto parts (TR CU 018/2011)
Medical devices (TR CU 037/2016)
High-power industrial low-voltage switchgear & power distribution cabinets (TR CU 004/2011 + TR CU 020/2011)
4. Standard CoC Certification Schemes (1C / 2C / 3C / 4C / 9C)
All CoC procedures use schemes with suffix C, defined by EEC Decision No.44:
1C – Serial production (most widely used)
Steps: Sample lab testing + full factory production audit + annual surveillance inspection during certificate validity
Validity: 1 / 3 / 5 years
Suitable: Mass-produced machinery, electrical equipment, PPE, fire gear
2C – Serial production with ISO 9001 factory certificate
Same as 1C, but factory audit simplified if valid ISO 9001 is provided
Annual surveillance includes QMS system review
3C – Single batch certification
Only lab testing for the specific shipment batch
No factory audit, no annual surveillance
Validity: One single shipment only; cannot reuse for future deliveries
Suitable: Small one-time order, custom special equipment
4C – Single unit certification
For one unique custom machine/device; test only the single unit
No audit, one-time use only
9C – Imported spare parts / components
For components installed inside certified main machinery; simplified testing rules
5. Mandatory Precondition: EAEU Authorized Representative
Overseas manufacturers cannot be the applicant/holder of EAC CoC:
Must appoint a legal entity registered in any EAEU country as official Authorized Representative (AR).
2026 Russia customs strict rule: Certificates held by Kazakh/Belarus AR face high rejection risk at Russian border; Russian LLC AR is recommended for Russian clearance.
A notarized power of attorney between factory and AR is a mandatory dossier document.

6. Full Application Workflow for EAC CoC
Step 1: Product Classification
Confirm TN VED HS code, match applicable TR CU regulation(s), select certification scheme (1C/2C/3C etc.)
Step 2: Sign notarized proxy with Russian EAEU Authorized Representative
Step 3: Compile full Russian-language technical dossier
Mandatory documents:
Application form signed by AR
Manufacturer business license, ISO 9001 certificate (notarized translation)
Notarized authorization agreement with AR
Russian technical passport, user manual, circuit/assembly drawings, BOM
Risk assessment report, product photos, EAC marking label draft
OEM agreement (if private label)
Step 4: Sample testing in accredited EAEU labs
Ship samples to Rosaccreditation lab to complete full safety, EMC, mechanical, climate tests (GOST 15150 low-temperature test for outdoor equipment) and obtain official Russian test protocol.
Step 5: Factory audit (only serial schemes 1C / 2C)
Certification body auditor inspects production lines, QC records, raw material control, calibration records, corrective action system. Non-conformities must be fixed before certificate issuance.
Step 6: Document review, issuance & unified registry filing
Cert body reviews all test and audit records; issues official CoC and uploads all data to the unified FGIS EAEU online registry with unique registry number + traceable QR code (mandatory for Russia 2026).
Step 7: EAC permanent marking
Print square EAC mark (min height ≥5mm) + QR code + registry number on product body or outer packaging before shipment.
Step 8: Annual surveillance audit (serial CoC 1C/2C)
Once per year during certificate validity; failure of surveillance leads to certificate suspension or cancellation.
7. Core Information Printed on EAC CoC
Certification body name, accreditation number, official seal
Applicant (EAEU Authorized Representative) full legal info
Foreign manufacturer name, factory address
Full product description, model series, TN VED HS customs codes
List of applicable TR CU Technical Regulations
Certification scheme (1C/2C/3C etc.)
Test protocol numbers, factory audit report number
Certificate issue date, expiry date, unique registry number
EAEU unified registry QR code
8. 2026 Critical Russia Enforcement Rules for CoC
Test reports from non-Rosaccreditation labs are invalid for Russian customs clearance.
EAC CoC without a linked QR code in the FGIS registry will result in cargo detention.
Serial CoC without completed annual surveillance audit is automatically invalid.
CoC issued by Kazakhstan/Belarus certification bodies may be rejected by Russian customs; Russian accredited cert bodies are prioritized.
Any model, material, or core technical parameter change requires re-testing and certificate amendment.
9. Consequences of No Valid EAC CoC
Goods detained, confiscated or forced return at all EAEU border customs
Heavy administrative fines for the EAEU importer (up to 20% of cargo value in Russia)
Removal from Wildberries / Ozon e-commerce platforms
Permanent customs blacklist for repeated violations
Illegal sale, installation, or operation of machinery prohibited under EAEU market supervision law
10. Supplementary Certificates That May Be Required Alongside CoC
SGR State Registration Certificate (Rospotrebnadzor): medical devices, cosmetics, food-contact parts, biocidal equipment
Fire Safety Certificate: Construction machinery, indoor electrical equipment with flammable components
Explosion-proof Ex test report: Supplementary detailed test records for TR CU 012/2011 Ex-proof products
