EAC and TR CU Certification on Industrial Automation Parts

EAC and TR CU Certification on Industrial Automation Parts: What a Sourcing Desk Cannot Issue for You

By the sourcing desk · An independent China sourcing desk is not a certification body: a single PLC, drive board, contactor or sensor does not arrive at the buyer's warehouse with an EAC certificate attached, and no desk that lacks accreditation can sign a TR CU declaration of conformity for it. The desk can issue a commercial invoice, packing list, bill of lading, and certificate of origin on request; the importer of record files the declaration, holds the technical file, runs the test program, and signs the mark. We are an independent distributor, not an authorized distributor of any manufacturer named here.

The Question You Are Asking, and Why It Stops at the Importer

A buyer in Moscow, Novosibirsk or Minsk often opens the conversation with two related prompts:

«Нужен ли сертификат ЕАС на промышленную автоматику?» (Is an EAC certificate required for industrial automation?)
«Кто отвечает за таможенное оформление при поставке в РФ?» (Who handles customs clearance on a shipment into the Russian Federation?)

Both questions land in the same place. EAC and TR CU conformity is a property of the product being placed on the EAEU market — that is, the finished machine, panel or system the importer sells, installs or commissions — and of the legal entity that places it. The conformity assessment, the test report, the technical file and the registered declaration are obligations on that entity. A foreign supplier, even one that is a franchised channel partner of the original manufacturer, cannot sign the declaration on the importer's behalf. An independent sourcing desk, by definition, cannot either.

What the desk can do is narrow the gap: quote the right part numbers, name the original manufacturer on every line, state the condition per line on the quote, and ship the documents that the importer's customs broker and certification body need to start work. What the desk cannot do is make the import pass conformity assessment on the importer's behalf.

What EAC and TR CU Actually Name

The two abbreviations are often confused and often used as if they were one thing. They are not.

EAC is the conformity mark — the Eurasian Conformity mark — a single graphic used across the Eurasian Economic Union (EAEU: Russia, Belarus, Kazakhstan, Armenia, Kyrgyzstan) for products that fall inside one or more of the technical regulations of the Customs Union.

TR CU (Технический регламент Таможенного союза / Technical Regulation of the Customs Union) is the regulation itself — a technical regulation covering a defined product group, requiring conformity assessment before the mark can be applied. There are many TR CUs, each covering a defined product group; the relevant one depends on what the product is and how it is being placed on the market. Examples that touch industrial automation most often include TR CU 004/2011 on low-voltage equipment, TR CU 020/2011 on electromagnetic compatibility, and TR CU 010/2011 on machinery safety, but the list is not exhaustive and the regulation that applies depends on the technical description, the rated voltage, and the end use.

The mark is a result. It is granted to a product after conformity assessment is complete, on the basis of a registered declaration or a certification by an accredited body. It is not a paper the desk can print and staple to a shipment.

Where the Line Sits: Component vs. Final Product

The most common misunderstanding, and the one that creates the most friction at customs, is between a component and a finished product.

A Delta DVP60ES200RE PLC, sold as a single programmable logic controller from the independent channel, is a component. It is a part. It enters the EAEU under a customs code for parts, not under the code for a finished machine. The importer's customs broker files it as a part; no EAC mark is applied to the part itself; the desk's commercial invoice describes it as a part, with the original manufacturer's name on the line.

A control cabinet built from that PLC plus a Schneider LC1D contactor, a Weidmüller WDU terminal block, a Phoenix Contact power supply and a SICK photoelectric sensor is a different object. It is a finished product, an assembly, intended to be installed into a production line. The cabinet builder — the importer, or a contract manufacturer acting for the importer — is the party placing it on the EAEU market. That party decides whether a TR CU applies, prepares the technical file, runs the test program if required, files the declaration, and applies the mark. The independent desk has no role in that decision, no role in that file, and no role in that mark.

Two practical consequences follow.

On the desk's side. The desk's quote lists each line as a component, names the manufacturer, names the series, states the condition, and never asserts conformity. The desk does not add "EAC included" to any line. The desk does not promise that any line will pass EAEU conformity assessment when assembled. Adding either would be a misrepresentation, and the desk declines the request when it is made.
On the importer's side. The importer is the one who engages a certification body, pays the assessment fee, holds the technical file, signs the declaration, and takes the regulatory risk for the finished product. The desk can pass through the manufacturer datasheet and any test certificate the original manufacturer publishes; the desk cannot issue a certificate the original manufacturer did not issue.

What the Desk Actually Issues on Every Shipment

For an order placed through /procurement and prepared for international transit, the desk issues a small, fixed set of documents. They describe the shipment. They do not certify the product.

Commercial invoice. Lists the buyer's name and address, the desk's name and address, every line by manufacturer and MPN, the quantity, the unit and line value, the currency, the incoterm, and the country of origin of the goods. Each line carries the condition as confirmed at quotation time. This is the document the importer's broker uses to file the customs declaration.
Packing list. Itemises the contents of each carton, the gross and net weights, and the carton dimensions. It is the document the broker reconciles against the invoice and against the physical goods at the warehouse.
Bill of lading or airway bill. Issued by the carrier, not the desk. Names the consignor, consignee, incoterm, and routing.
Certificate of origin. Issued on request where the chamber of commerce or the importing country's preferential treatment requires it. The desk prepares the application; the chamber signs. The desk does not sign origin certificates itself.

That is the complete list. It does not include an EAC certificate, a TR CU declaration of conformity, an exemption letter, or any paper that purports to give the buyer permission to place the goods on the EAEU market. The desk does not issue those documents because no desk without EAEU accreditation can.

Where the Buyer Must Take Over

Once the goods land at the EAEU border and clear customs as components, four steps belong to the buyer, not the desk.

Confirm whether a TR CU applies to the finished product. The decision is made on the technical description of the assembly (the cabinet, the machine, the system), on its rated voltage, on its intended environment, and on which TR CU regulations cover that combination. The desk does not make this call.
Engage an EAEU-accredited certification body or, where the regulation allows, file a declaration of conformity directly. The buyer selects the body, signs the application, pays the fee, and supplies the technical file.
Hold the technical file. Drawings, bill of materials, manufacturer datasheets, test reports, risk assessments, and the instructions for use. The desk can pass through the manufacturer datasheet on request; the rest is the buyer's file.
Register the declaration and apply the EAC mark on the finished product. The mark goes on the cabinet nameplate or on the system documentation. It does not go on the individual Delta PLC or Schneider contactor.

For used and refurbished components, an additional question often arises: does the importer's conformity assessment accommodate a part that has a service history? The desk's role there is limited to disclosing the part's condition honestly — new surplus, refurbished with a bench-test record on file, or used as removed — on a per-line basis. The buyer decides whether that disclosure is acceptable inside the buyer's own conformity file.

Why the Desk Will Not "Help" with a Workaround

The same buyers who ask about EAC sometimes ask about a workaround. The request may be phrased as a favour — "just stamp the invoice as compliant" — or as a service — "can you arrange the certificate through a partner?" The desk declines both.

The reason is not commercial caution alone. Issuing or arranging documents that misrepresent conformity status is a misrepresentation to the EAEU customs authority and to the buyer's end customer. It exposes the buyer to seizure, retroactive assessment, and the regulatory cost of doing the work properly after the fact. It exposes the desk to a category of risk that no commercial margin justifies. The desk does not arrange certificates through third parties; the desk does not back-date declarations; the desk does not sign paperwork that names a manufacturer the desk is not. Requests framed as workarounds are declined at the inquiry stage.

The desk also declines to advise on whether a particular TR CU applies to a particular part. That determination is a regulatory and engineering judgement that sits with the buyer's certification body. The desk's job is to make the underlying sourcing honest and traceable; the certification body's job is to make the finished product conform.

What This Looks Like in a Real Order

A buyer in Yekaterinburg orders a 24-line BOM that mixes Delta DVP-series PLCs (DVP60ES200RE, DVP15MC11T, DVP80ES200R, DVP32EH00T3-L on the rack), Schneider LC1D contactors, Omron E2E proximity sensors and Weidmüller WDU terminal blocks. The order is placed with the desk under /procurement; the quote returns each line by manufacturer and series, with condition stated per line, and an incoterm stated on the quotation.

The desk prepares the shipment: each line picked from the catalogued inventory, the photos taken before sealing, the invoice and packing list drafted, the carrier booked, and the documents handed to the buyer before the goods leave the consolidation point. The buyer receives the shipment, files the customs declaration through a broker in Yekaterinburg, pays the import duties and VAT, and receives the components into the buyer's warehouse as parts.

The buyer then assembles those parts into a control cabinet. At that point the buyer — not the desk — owns the question of which TR CU applies, engages the certification body, files the declaration, and applies the EAC mark on the finished cabinet nameplate. The Delta PLC inside the cabinet does not carry an EAC mark of its own; the cabinet that contains it does. The desk's role in that chain stops at the warehouse door.

This is not a special case. It is how every shipment crossing the EAEU border works, regardless of whether the seller is a franchised channel partner, an independent desk, or a marketplace. The line sits at the same place for all of them.

Five Cases the Desk Declines Up Front

The desk declines at inquiry, before the quote is drafted, in the following situations. Each is logged the same way.

"Stamp the invoice as EAC compliant." The invoice states the goods as invoiced. It does not certify them.
"Add a conformity declaration to the shipment." The desk does not issue conformity declarations.
"Arrange the certificate through a partner and bill it back." The desk does not partner for the issuance of documents it cannot issue itself.
"Skip the datasheet on the line; the buyer will figure it out at customs." The datasheet is part of what the buyer needs to file. The desk passes it on when it is available.
"Mark the line as new so the customs value is higher." Condition is stated honestly per line. Misstating condition is a misrepresentation to the broker and to the EAEU customs authority.

The desk's position on these requests is the same in writing as in conversation: we screen end users and end uses, classify before quoting, and decline transactions that cannot be screened.

Where This Article Stops

The desk is a sourcing desk. It sources components by manufacturer, series and MPN, quotes per line, conditions per line, and ships under an incoterm stated on the quotation. It does not hold EAC or TR CU accreditation. It does not issue conformity declarations. It does not give legal opinions on whether a particular TR CU applies to a particular assembly. Where a buyer's project requires conformity assessment, the importer's certification body is the right counterparty; the desk's role is to make the underlying parts list, datasheet and condition record available to that body without misrepresentation.

The next step for a buyer who already has a BOM is to send your BOM through /procurement for an indicative per-line quote; the next step for a buyer who needs to discuss the conformity path is to open the question with the importer's certification body in parallel with the sourcing conversation. The two tracks are independent.

Data Notes

All component-level specifications cited in this article (Delta DVP-series programmable controllers, Schneider LC1D contactors, Omron E2E proximity sensors, Weidmüller WDU terminal blocks) are described at the series level only; per-line condition, manufacturer, and incoterm are stated on the quotation, not on the page. Data through September 2026. The desk's commercial invoice, packing list, bill of lading or airway bill, and certificate of origin are the only paper the desk signs; EAC and TR CU conformity assessment is not in that set. Where a buyer's project requires a TR CU declaration, the importer of record engages an EAEU-accredited certification body and signs the declaration on the importer's own technical file. The desk does not issue declarations, does not back-date paperwork, and does not hold itself out as authorised to certify on any party's behalf. This is an independent distributor; we are not an authorized distributor for any of the manufacturers named.

FAQ

Does the supplier's paperwork come with an EAC mark on the PLC itself?

No. A programmable logic controller sold as a single component, including a Delta DVP60ES200RE, enters the EAEU as a part. The part has no EAC mark of its own; the part's paperwork lists the manufacturer, MPN, condition per line, and incoterm. The EAC mark is applied to the finished assembly (the cabinet or the machine) by the importer of record after conformity assessment, never by the supplier of the component.

Who signs the TR CU declaration of conformity?

The declaration is signed by the legal entity that places the finished product on the EAEU market. That entity is the importer, the cabinet builder, or the contract manufacturer acting for the importer. A foreign supplier, including an independent China sourcing desk, cannot sign the declaration on the importer's behalf; the signature is part of the conformity assessment and is part of the importer's regulatory file.

Is an EAC certificate required for every industrial automation part?

No. EAC and the underlying TR CUs apply to finished products placed on the market, not to every component that enters the country as a part. A single PLC, a single contactor, a single terminal block imported as a component is filed under a customs code for parts and is not marked. The TR CU question becomes relevant when the importer assembles those parts into a cabinet, machine or system that is itself placed on the market.

Can the supplier arrange the EAC paperwork through a partner in the EAEU?

No. The supplier does not arrange conformity paperwork through a partner, and any invoice or declaration that names the supplier as the issuing party when the supplier lacks EAEU accreditation is a misrepresentation. Where a buyer needs conformity assessment, the right counterparty is the importer's own certification body, engaged by the importer on the importer's own file.

What documents does the supplier actually issue on an EAEU-bound shipment?

The supplier issues the commercial invoice and the packing list on every shipment, and arranges the bill of lading or airway bill through the booked carrier. A certificate of origin can be prepared on request through the chamber of commerce where the buyer's customs treatment requires it. These documents describe the shipment as goods; they do not certify the goods as conforming.

Who handles customs clearance on a shipment into the Russian Federation?

Customs clearance is filed by the importer of record, normally through a licensed customs broker in the destination country. The supplier's role stops at handing the commercial invoice, packing list, bill of lading or airway bill, and any certificates of origin to the broker. The supplier does not file the declaration on the buyer's behalf and does not act as the declarant.

What condition terms appear on the line for a refurbished or used component?

Each line states the condition as confirmed on the quotation: new surplus for unused components from non-franchised channels, refurbished for units that have been bench-tested with a record on file, and used for parts removed from equipment in the condition in which they were removed. The condition is stated per line; the desk does not merge condition terms across lines and does not upgrade a used line to refurbished in the paperwork.
