TR CU (EAC) Technical Regulations Full Guide
1. Basic Definition
TR CU = Технические регламенты Таможенного союза
English: Technical Regulations of the Eurasian Customs Union / EAEU Technical Regulations
Unified mandatory safety laws for the 5 EAEU member states: Russia, Belarus, Kazakhstan, Kyrgyzstan, Armenia
Legal authority: Issued by the Eurasian Economic Commission (EEC), directly override all national GOST-R / GOST-K / GOST-BY standards
Compliance outcome: Products passing assessment get EAC marking, with either TR CU CoC (Certificate) or TR CU DoC (Declaration)
Core rule: If your product falls under any TR CU regulation, national GOST certification is invalid for customs clearance; only EAC is accepted.

2. Core Legal Features of All TR CU
Uniform cross-border standards
One set of safety, chemical, mechanical, electrical rules for all 5 countries; no separate national testing differences for TR CU-covered goods.
Clear risk classification built into each regulation
Every TR CU explicitly defines which goods need CoC (high-risk, third-party certification) and which only need DoC (low/medium-risk, self-declaration).
Mandatory unified conformity assessment schemes
Standard scheme codes:
CoC schemes: 1C,2C,3C,4C,9C (require lab testing + optional factory audit)
DoC schemes: 1D,2D,3D,4D,5D,6D (no mandatory factory audit)
Mandatory Russian-language technical dossier
All manuals, test protocols, safety passports must be fully translated to Russian to apply for CoC/DoC.
Unified EAEU official registry (FGIS)
All valid CoC & DoC are uploaded to a shared database; customs cross-check registry numbers + QR codes during inspection (2026 strict rule in Russia).

3. Classification of Main TR CU Regulations (By Product Category)
Group 1: Electrical & Electromagnetic Compatibility (Most Common for Electronics)
TR CU 004/2011 – Low Voltage Equipment Safety
Scope: AC 50V–1000V / DC 75V–1500V all electrical goods
High-risk industrial power gear → CoC
Small household appliances, chargers, lamps → DoC
TR CU 020/2011 – Electromagnetic Compatibility (EMC)
All powered electronic products (machinery, home appliances, telecom equipment)
Almost always paired with TR CU 004/2011 for dual compliance.
Group 2: Machinery, Explosion-Proof & Pressure Equipment (Industrial Core)
TR CU 010/2011 – Safety of Machinery & Equipment
Full coverage: CNC machines, excavators, forklifts, agricultural tractors, woodworking tools, packaging lines, welding equipment
Heavy machinery, lifting gear → CoC; small hand tools → DoC
TR CU 012/2011 – Equipment for Explosive Atmospheres (Ex-proof)
All mining, chemical, oil & gas explosion-proof electricals, pumps, lighting, control panels
Mandatory CoC only (no DoC allowed)
TR CU 032/2013 – Safety of Pressure Equipment
Boilers, gas cylinders, pressure vessels, high-pressure piping (working pressure >0.05 MPa)
Class III/IV high-risk vessels → CoC; small low-pressure tanks → DoC
Group 3: Lifts, PPE, Fire Safety (Life-Saving High-Risk Goods)
TR CU 011/2011 – Safety of Lifts & Escalators
Passenger lifts, freight elevators, escalators, safety components
Only CoC permitted
TR CU 019/2011 – Personal Protective Equipment (PPE)
Category 3 high-risk PPE (fall harnesses, gas masks, chemical suits) → CoC
Simple safety gloves, basic goggles → DoC
TR CU 043/2017 – Fire Safety Equipment
Fire extinguishers, smoke detectors, fire doors, emergency lighting
Mandatory CoC for all fire-fighting gear
Group 4: Children & Toy Products (Strict Consumer Safety)
TR CU 007/2011 – Children & Teenage Articles
Strollers, child car seats, baby beds, feeding bottles, pacifiers
Mandatory CoC
TR CU 008/2011 – Safety of All Toys
Plush, plastic, electric, ride-on toys
Only CoC allowed; DoC is illegal
Group 5: Vehicles & Auto Parts
TR CU 018/2011 – Safety of Wheeled Vehicles
Cars, trucks, motorcycles, ATVs, core safety spare parts (brakes, tires, airbags, seatbelts)
Complete vehicles & critical safety components require CoC.
Group 6: Cosmetics, Light Industry, Furniture, Packaging (Mainly DoC)
TR CU 009/2011 – Perfumery & Cosmetics
Creams, shampoo, makeup; requires DoC + supplementary SGR state registration
TR CU 017/2011 – Light Industry Goods
Clothing, shoes, textiles, fabrics (DoC)
TR CU 025/2012 – Furniture Safety
Household & office furniture (DoC)
TR CU 005/2011 – Packaging Safety
Food & consumer product packaging (DoC)
Group 7: Food, Agricultural, Fuel & Chemical Products
TR CU 021/2011 (Food safety), TR CU 013/2011 (vehicle fuels), TR CU 041/2017 (industrial chemicals)
Most food & chemical goods require DoC + additional Rospotrebnadzor registration.
Group 8: Railway & Special Transport
TR CU 001/002/003 – Rolling stock, high-speed trains, railway infrastructure (CoC only)
4. How to Judge Which TR CU Applies to Your Product
3-step standard classification workflow:
Provide your product name, full technical parameters, and TN VED (EAEU HS customs code)
Cross-check against the official EEC TR CU product scope list to match the relevant regulation(s)
Many electronics/machinery need compliance with two TR CU simultaneously (e.g., TR CU 004 + TR CU 020 for motors)
Check risk level defined in the matched TR CU to confirm CoC or DoC requirement.
5. TR CU vs National GOST-R / GOST-K / GOST-BY – Legal Priority
If a product is covered by any TR CU → EAC CoC/DoC is mandatory, national GOST documents are rejected by all EAEU customs.
If no matching TR CU exists for your goods → national mandatory GOST certification (GOST-R for Russia only, GOST-K for Kazakhstan only, GOST-BY for Belarus only) is required for single-country import.
Voluntary GOST certificates can be applied alongside valid EAC for government tenders, but cannot replace EAC for customs clearance.
6. Consequences of Non-Compliance with TR CU
Customs detention, forced return or full confiscation of cargo
Heavy administrative fines for the EAEU importer/authorized representative (up to 20% of goods value in Russia)
Removal from e-commerce platforms (Wildberries, Ozon, Kaspi.kz)
Permanent customs blacklist for repeated violations
Ban on installation, sale or operation of machinery/equipment in the EAEU
7. Short Summary of Key Rules
TR CU = unified EAEU safety laws; EAC marking proves compliance
Each TR CU splits products into high-risk (CoC) and low-risk (DoC)
One EAC document covers all 5 EAEU countries, replacing separate national GOSTs
Multiple TR CU may apply to one product (electrical goods almost always need 004 + 020)
No TR CU coverage = apply country-specific GOST-R / GOST-K / GOST-BY
