Certification under TR CU 004/2011 “On the Safety of Low-Voltage Equipment”

TR CU 004/2011 is one of the key EAEU technical regulations for low-voltage electrical equipment. If the product falls within the scope of the regulation, conformity assessment becomes a mandatory condition for lawful import and sales in the EAEU countries.

We work with European manufacturers and trading companies seeking access to the EAEU market. It is important to understand that the familiar European compliance logic, including CE, and the EAEU logic are different systems. Therefore, our task is not to “issue a paper”, but to build the procedure in such a way that the document is robust: the correct form of conformity assessment, the correct scheme, testing to the required standards, and a technical file without weak points.

What is TR CU 004/2011 and what is it for?

The regulation establishes safety requirements for low-voltage equipment and defines the rules for conformity assessment. In practical terms, it answers a simple question: is the product safe under normal operation and foreseeable conditions of use – in terms of electrical risks, overheating, design, marking, and operating documents.

For business, risks arise not “in theory”, but at specific points: during import, market surveillance, at the client’s site, in tenders, and in procurement. That is why we pay more attention not to a polished “final file”, but to the evidence base and the correctness of execution.

Which products are subject to conformity assessment under TR CU 004/2011?

Mistakes most often begin with oversimplification “by product name”. In the EAEU, intended purpose, parameters, completeness, and supply format matter more: the product is supplied as an individual unit, as a set, as a module, or as part of equipment.

To determine whether the regulation applies and which form of assessment is required, at the outset we ask for a short minimum: what the product is, how it is used, what modifications exist, and how supplies are organized. After that, it becomes clear which requirements actually apply and how to build the procedure without rework.

Certificate or declaration: which to choose under TR CU 004/2011?

The key point is to determine the form of conformity assessment correctly. The legal mechanics here are straightforward:

EAEU Certificate of Conformity – issued through an accredited certification body (the certificate is issued by the body).
EAEU Declaration of Conformity – issued in the applicant’s name (the declaration is registered by the applicant), and responsibility for the correctness of the evidence lies with the applicant.

We help select the form and scheme so that you do not end up in a situation where “the document exists, but it is weak”: the wrong scheme, disputable wording, unsuitable testing standards, or an incomplete technical file.

How we determine exactly what you need

We start with a diagnostic review. It is a quick stage that saves weeks of corrections: we define the purpose and characteristics of the product, the scope of supply, the supply scenario (batch/serial production), the state of the documentation, and the project roles (applicant/authorized representative if the manufacturer is not present in the EAEU).

After the diagnostic review, you get a clear picture:

• which document is required (certificate or declaration),
• which scheme fits your supply format,
• which tests and documents are actually needed,
• where the risks may lie and how to close them in advance.

Stages of obtaining a certificate/declaration under TR CU 004/2011

We build the process without “magic” and without unnecessary circles. At the start, we collect the basic package, check it for compliance with the requirements, and, if necessary, help bring the documentation into working shape – this is usually faster and more reliable than “trying to slip through”.

Next, we organize testing in an accredited laboratory: we agree the test program, support sample selection/transfer, and make sure that the test reports cover the requirements of the regulation and the selected scheme.

If serial production is involved and the scheme provides for production assessment or inspection control, we define this in advance: what obligations will apply during the validity period and how to prepare for them.

Ostatni krok zależy od formy:

• The final step depends on the form:
• The declaration is registered by the applicant in accordance with the established procedure.

We control the correctness of the information so that the document is valid and verifiable in the register.

Timing and cost: what affects the price?

We do not tie the service to a specific country – we work with European clients “for the EAEU market”. Therefore, timing and cost are determined not by geography, but by the volume of work and the evidence required.

In practice, the price is affected by the form of assessment (certificate/declaration), the scheme (batch/serial), the scope of testing, and the readiness of the technical documentation. The better the source materials are prepared and the more accurately the applicability of the requirements is defined, the fewer unnecessary steps there are and the faster the project proceeds.

Advantages of certification under TR CU 004/2011

A correctly issued document under TR CU 004/2011 is not a “tick-box”, but an instrument of market access and risk management.

It allows products to be lawfully placed on the market and sold in the EAEU countries.

It reduces the likelihood of border delays and questions during market surveillance.

It simplifies work with distributors and B2B clients: they have fewer doubts about compliance and supply transparency.

How to choose an accredited certification body?

The quality of the result largely depends on who performs the conformity assessment and how the evidence base is assembled. We work through a partner network and select competencies to fit the task, but if you choose partners yourself, keep to a simple guideline: accreditation in the required area, practical experience with your type of product, and clear communication.

If you are promised “everything in one day without documents”, this almost always means the risk of a weak result. In the EAEU, weaknesses show up later – when the document starts being checked.
