questions
Which products require a declaration under CU TR 004?
Under CU TR 004, low-voltage equipment that is not on the list of products subject to mandatory certification requires a declaration.
Low-voltage equipment is equipment rated from 50 to 1,000 V AC or from 75 to 1,500 V DC, inclusive.
Examples include PCs and components, power tools, cables, wires, cords, electricity distribution equipment and electrical installation controls. A declaration under CU TR 004 requires documents demonstrating compliance with the regulation’s safety requirements. These may include:
  • test reports
  • quality certificates
  • quality certificates
  • operating instructions, etc.
The CU TR 004 declaration of conformity is prepared using these documents and registered in the unified EAEU declaration registration system.
What certification does my company need?
Certification is the process of confirming that products or services meet specified quality, safety and environmental standards.
Certification may be mandatory or voluntary, depending on legal and market requirements.
    To determine the certification your company needs, consider the following factors:
  • Your business activities and the characteristics of your products or services.
    For example, food manufacturers need a certificate of conformity with sanitary and epidemiological rules and standards. Medical service providers need a medical activity licence and a certificate of conformity with medical care quality standards.
  • The country or region where you plan to sell your products or services. Certification requirements may vary by market.
    For example, exports to the European Union must comply with European standards and directives (European standards and CE marking). Operating in the Russian Federation requires compliance with Russian rules and standards (GOST and RST).
  • The expectations and requirements of potential customers and partners. In some cases, voluntary certification can strengthen trust in your company and improve its market competitiveness.
    For example, a service provider may benefit from ISO 9001 certification demonstrating service quality and process management. A producer of organic or environmentally friendly products may benefit from organic farming certification confirming the absence of harmful chemicals and GMOs.
Certification or declaration: how can you determine whether CU TR 032 applies?
If you manufacture or sell equipment operating under excess pressure, you need a document confirming compliance with the Customs Union Technical Regulation on the Safety of Equipment Operating under Excess Pressure (CU TR 032/2013).
Depending on the equipment’s risk category, this document may be a certificate or a declaration.
How is the risk category determined?
    Consider the following parameters:
  • type of working medium (group 1 or 2);
  • maximum allowable working pressure;
  • nominal diameter (DN);
  • vessel volume (V) or nominal boiler heat output (Pn).
Based on these parameters, equipment is divided into four risk categories: I, II, III and IV.
Higher categories entail stricter safety requirements and more complex conformity assessment procedures.
Equipment in risk categories I and II uses the declaration form of conformity assessment. The manufacturer or supplier declares compliance with CU TR 032/2013 and takes responsibility for it. A declaration requires sample testing in an accredited laboratory and test reports. Technical documentation must also be prepared and the declaration completed using the unified form.
Equipment in risk categories III and IV uses certification. The manufacturer or supplier submits the required documents and equipment samples to an accredited certification body for examination. The body verifies compliance with CU TR 032/2013 and issues a certificate for a specified period.
To determine whether CU TR 032/2013 applies, you need to know the equipment parameters and risk category. This helps you choose the appropriate conformity assessment form and avoid errors when selling products in Customs Union countries.
What is a safety justification?
A safety justification describes potential risks associated with the use of machinery and equipment and measures to prevent or reduce them. It is developed at the design stage and accompanies the product throughout its life cycle.
A safety justification is required to demonstrate compliance with Customs Union Technical Regulation 010/2011 on the Safety of Machinery and Equipment. Its sections cover product characteristics, safety principles, risk analysis, personnel requirements, quality management, environmental protection, commissioning and disposal.
