EAC CoC vs EAC DoC Full Comparative Guide (2026 Official EAEU Rules)
Both documents carry equal legal validity for customs clearance & sales across all 5 EAEU nations (RU/BY/KZ/KG/AM). The applicable type is strictly defined by the corresponding TR CU technical regulation — you cannot choose freely.
1. Core Comparison Table
Comparison Item    EAC CoC (Certificate of Conformity)    EAC DoC (Declaration of Conformity)
Issuing Body    Third-party certification body accredited by Rosaccreditation    Self-signed & filed by an EAEU local legal entity (importer / authorized representative)
Document Format    Special anti-counterfeit security paper with hologram, official seal & unique serial number    Plain A4 white sheet; only the FGIS registry number is legally binding
Mandatory Lab Test    ✅ Required for all schemes; tests must be completed in Rosaccreditation-accredited labs (Russian labs preferred for Russia clearance in 2026)    Flexible: Factory internal test / CE/CB reports accepted for most schemes (1D/2D); only 3D/4D require accredited lab testing
Factory Audit Rule    ✅ Mandatory on-site audit for serial production schemes (1C/2C); annual surveillance audit during validity period    ❌ No factory audit, no annual follow-up inspection at all
Legal Liability    Shared liability: Certification body + EAEU authorized representative    100% full legal responsibility borne solely by the EAEU declarant (local importer)
Conformity Assessment Schemes    1C, 2C, 3C, 4C, 9C (suffix C for Certificate)    1D, 2D, 3D, 4D, 5D, 6D (suffix D for Declaration)
Processing Lead Time    4–12 weeks (testing + factory audit + file review)    7–15 working days (only document registration)
Overall Cost    High (lab testing fee + audit + annual surveillance charges)    Low (only document translation & registry service fee)
Applicable Product Risk    High-risk goods that may cause explosion, electric shock, mechanical fatal injury    Medium & low-risk consumer/light industrial goods
Max Valid Term    Up to 5 years (serial production) / single batch only    Up to 5 years (serial production) / single batch only
Market & Tender Recognition    Preferred for government bids, industrial projects, state procurement    Valid for retail, wholesale & e-commerce (Ozon/Wildberries); many state tenders require CoC as extra proof
Post-certification Maintenance    Mandatory yearly surveillance audit to retain validity    No maintenance work required after registration

2. Mandatory Product Scope for EAC CoC (DoC Is Illegal & Rejected by Customs)
These high-risk products are explicitly required to use CoC in their TR CU regulation:
TR CU 012/2011 Explosion-proof Ex equipment (mining, oil & gas electrical devices)
TR CU 008/2011 All toys & children’s play goods
TR CU 007/2011 Infant articles: strollers, child car seats, baby bottles, pacifiers
TR CU 011/2011 Lifts, escalators & all elevator safety components
TR CU 032/2013 High-risk Class 2–4 pressure vessels, boilers, gas cylinders
TR CU 010/2011 Heavy industrial machinery: excavators, cranes, forklifts, CNC machines, welding equipment
TR CU 043/2017 Fire safety equipment (fire extinguishers, smoke detectors, fire doors)
TR CU 019/2011 Category 3 high-risk PPE: gas masks, fall protection harnesses, chemical full-body suits
TR CU 018/2011 Complete vehicles + core auto safety parts (tires, brakes, airbags, seatbelts)
TR CU 037/2016 All medical devices
High-current industrial power distribution cabinets & large transformers (TR CU 004/020)
3. Permitted Scope for EAC DoC (CoC Can Be Applied Voluntarily)
Medium/low-risk goods allowed to use DoC for customs clearance:
TR CU 004+020 Small household electrical appliances: kettles, fans, LED lamps, phone chargers, air fryers
TR CU 017/2011 Light industry goods: clothing, shoes, textiles, bedding, bags
TR CU 025/2012 General household & office furniture (excluding infant furniture)
TR CU 010/2011 Simple hand tools & portable small power tools
TR CU 005/2011 Plastic, paper & metal packaging materials
TR CU 009/2011 Cosmetics & perfumery (extra SGR state registration required)
Construction finishing materials: paint, wallpaper, plastic drainage pipes, floor tiles, thermal insulation
Stationery, ceramic/glass tableware, daily plastic containers
Category 1 simple PPE: ordinary safety gloves, basic dust masks, regular safety goggles
4. Shared Mandatory Rules for Both CoC & DoC
EAEU Authorized Representative Is Compulsory
Chinese overseas manufacturers cannot be the holder/applicant of either document. You must appoint a legal entity registered within the EAEU (Russian LLC recommended for Russian customs clearance in 2026) with a notarized Russian power of attorney.
Unified EAC Marking Requirement
Square EAC symbol minimum height ≥5mm, permanently printed on product body or outer packaging; traceable QR code linked to the FGIS unified registry is mandatory for Russian border inspection in 2026.
Official Unified Database Registration
All valid CoC & DoC must be uploaded to the federal FGIS registry; unregistered documents are deemed counterfeit and will lead to cargo detention.

DoC query portal: https://pub.fsa.gov.ru/rds/declaration
Full Russian-language Technical Dossier
Manuals, technical passports, drawings, test protocols must be fully translated into Russian, with consistent model & brand information across all files.
Batch vs Serial Validity Logic
Batch documents only apply to one single shipment; serial documents allow unlimited shipments within 1–5 years.
5. Key Legal Rule You Must Follow
If your product falls into the mandatory CoC list, a DoC will be fully rejected by EAEU customs, resulting in cargo seizure, fines, and forced return.
For products eligible for DoC, you may voluntarily upgrade to CoC if required by buyers or government tender projects (CoC has higher third-party credibility).
National GOST-R / GOST-K / GOST-BY cannot replace either CoC or DoC for goods covered by any TR CU regulation.
6. Practical Selection Guide
Scenario 1: High-risk product (toys, Ex-proof, lifts, heavy machinery, medical devices)
Only option: Apply EAC CoC
Long-term mass export: Scheme 1C
One-time small trial shipment: Batch scheme 3C
Scenario 2: Medium/low-risk consumer goods (home appliances, furniture, clothing)
Regular retail & wholesale export: EAC DoC Scheme 1D (fastest & lowest cost)
Buyers request official accredited lab test reports: DoC Scheme 3D
Government tender requires third-party certified document: Voluntarily apply EAC CoC
Scenario 3: Single small trial order of low-risk goods
EAC DoC Scheme 2D (batch declaration, no mandatory testing)
7. Consequences of Using the Wrong Document Type
Goods detained, confiscated or returned at all EAEU customs ports
Administrative fines for the local EAEU importer (up to 20% of total cargo value in Russia)
Product delisting from Wildberries, Ozon, Kaspi.kz e-commerce platforms
Permanent customs blacklist for repeated non-compliance violations
