TR CU CoC vs TR CU DoC Complete Comparison & Selection Rules
Core Legal Principle
Every single TR CU Technical Regulation clearly splits goods into two fixed lists:
Goods that must use TR CU CoC (Certificate) — high-risk, DoC is illegal and will be rejected by customs
Goods that only allow TR CU DoC (Declaration) — medium/low-risk, CoC can be applied voluntarily (for bidding), but DoC is sufficient for customs clearance
You cannot freely choose; the product category under the corresponding TR CU determines which document you need.

1. Fundamental Difference Table
Comparison Dimension    TR CU CoC (Certificate of Conformity)    TR CU DoC (Declaration of Conformity)
Issuing Body    Rosaccreditation-accredited third-party certification body    Self-signed & filed by EAEU local legal entity (importer/authorized rep)
Document Form    Anti-counterfeit security paper with hologram & official seal    Plain A4 paper; only registry number is legally valid
Factory Audit    Mandatory for serial schemes (1C/2C); annual surveillance audit during validity    No factory audit, no annual follow-up inspection
Lab Testing    Mandatory full test in Rosaccreditation accredited labs (2026 Russia requires Russian labs)    Flexible: factory internal test / CE/CB reports accepted; only scheme 3D/4D needs accredited lab tests
Legal Liability    Shared: cert body + EAEU authorized representative    100% full liability solely borne by local declarant
Processing Time    4–12 weeks (testing + audit + document review)    7–15 working days (file registration only)
Total Cost    High (lab test + audit + annual surveillance fees)    Low (only document & registry service fee)
Applicable Risk Level    High-risk products (life hazard, explosion, electric shock)    Medium / low-risk consumer & light industrial goods
Valid Schemes    1C,2C,3C,4C,9C    1D,2D,3D,4D,5D,6D
Max Validity    5 years (serial) / single batch    5 years (serial) / single batch
Tender Recognition    Preferred for government, industrial & state procurement    Accepted for retail, general wholesale; many state bids require CoC additionally

4. Certification Schemes Explanation
CoC Schemes (Suffix C)
1C: Serial mass production (most popular) — lab test + factory audit + annual surveillance
2C: Serial production with valid ISO 9001 — simplified audit
3C: Single batch certification — test only, no audit, one shipment only
4C: Single unique custom machine, one-time use
9C: Spare parts/components for certified main equipment
DoC Schemes (Suffix D)
1D: Serial production, factory internal test reports acceptable (lowest cost, most used)
2D: Single batch declaration, no mandatory lab test
3D: Serial production, mandatory accredited lab test (buyers often request)
6D: Serial production with ISO 9001 QMS
5. Shared Mandatory Rules for Both CoC & DoC
No Chinese factory as direct holder
Must appoint an EAEU registered legal entity as Authorized Representative; Russian LLC recommended for Russian border clearance (2026 customs policy). Notarized Russian power of attorney is required.
Unified EAC marking requirement
Square EAC logo min height ≥5mm, permanent on product/packaging; traceable QR code linked to FGIS registry mandatory in Russia.
Unified official database verification
CoC query: https://pub.fsa.gov.ru/rss/certificate
DoC query: https://pub.fsa.gov.ru/rds/declaration
Technical dossier in Russian
All manuals, technical passports, drawings, test reports must be fully translated into Russian.
Validity logic
Batch document = only valid for one single shipment; serial document allows unlimited shipments within 1–5 years.
6. Practical Selection Guide
Scenario 1
Product in the mandatory CoC list (toys, Ex-proof, lifts, heavy machinery)
→ Only option: Apply TR CU CoC (scheme 1C for mass export / 3C for one-time batch)
Scenario 2
Medium/low-risk consumer goods (small home appliances, furniture, clothing)
Regular export & retail sales: Choose DoC scheme 1D (fast, low cost)
Buyers or state tenders demand third-party certified document: Voluntarily upgrade to CoC
Scenario 3
Small one-time trial order, low-risk goods
→ DoC scheme 2D (batch declaration, shortest timeline)
Scenario 4
Long-term mass export, customer requires official lab test reports
→ DoC scheme 3D or serial CoC
7. Penalties for Wrong Document Type
Goods detained, confiscated or forced return at all EAEU customs ports
Heavy fines on EAEU importer (up to 20% of cargo value in Russia)
Product delisting from Wildberries/Ozon/Kaspi.kz
Permanent customs blacklist for repeated non-compliance
