EAC and TR CU for Industrial Automation Parts: What an Independent Sourcing Desk Cannot Issue
EAC and TR CU for Industrial Automation Parts: What an Independent Sourcing Desk Cannot Issue
An independent China-based industrial automation sourcing desk does not hold, issue, or apply for EAC or TR CU conformity certification. EAC and TR CU mark a product's conformity with the EAEU technical regulations; conformity assessment rests with the importer of record or equipment manufacturer, not the component supplier. The desk sources parts, documents their condition, and provides the commercial paperwork that travels with the consignment.
What EAC and TR CU Cover, and What They Do Not
EAC is the conformity mark used across the Eurasian Economic Union — Russia, Belarus, Kazakhstan, Armenia, Kyrgyzstan — for products that fall inside one or more of the technical regulations known collectively as TR CU (Technical Regulations of the Customs Union). Each TR CU covers a defined product scope: low-voltage equipment, electromagnetic compatibility, machinery safety, explosion protection, and others. The mark on a product, or the certificate accompanying it, attests that a named responsible party has run the conformity procedure the relevant TR CU requires for that scope.
Two clarifications matter for a buyer of PLC modules, drives, sensors, contactors and HMI panels. First, the regulation is product-by-product and scope-by-scope; a certificate that covers one component does not automatically cover another, even when both come from the same shipment. Second, the responsible party is normally the entity placing the product on the Union market — the importer of record for a stand-alone component, the equipment manufacturer for a machine that includes the component. A foreign supplier that ships a part to a buyer in the Union is not, by virtue of shipping, the responsible party.
What TR CU does not cover is equally important. It is not a quality mark for the supplier's commercial process, it is not a warranty issued by the supplier, and it is not an authorization from a manufacturer to distribute a brand. Those are separate questions, with separate answers, and conflating them is one of the most common ways a quote conversation drifts away from what a desk can actually deliver.
This is also why a sourcing desk cannot tell a buyer whether a specific PLC module, VFD, sensor or contactor requires EAC certification for a given shipment. The determination depends on the component, its intended use, the equipment it goes into, and the technical regulations in force at the time of import. A desk that guesses anyway is a desk that has stopped being useful on this question.
Why an Independent Desk Does Not Issue EAC or TR CU
An independent industrial automation sourcing desk operates without manufacturer authorization, without an EAC or TR CU certificate of its own, and without the laboratory infrastructure that would be needed to run a conformity assessment. That is not a gap in the service — it is the structure of the service. The independence is what allows the desk to source across the supply chain, including parts the franchised channels list as obsolete, allocation-only, or out of stock; that same independence is the reason the desk does not hold the certifications a manufacturer-authorized distributor would.
Three practical limits follow.
The desk cannot apply for EAC or TR CU on the buyer's behalf. The applicant on a TR CU conformity assessment is the party with a documented presence in the Union market — usually the importer of record, the equipment manufacturer, or a notified body acting for one of them. A China-based desk sitting on the supply side of the transaction is not in that position.
The desk cannot supply a certificate it does not hold. Where a finished component, a tested assembly, or a controlled batch arrives at the desk from a third party, the certificate that should accompany it is the certificate the third party holds. If no certificate exists, no certificate can be added by re-stamping paperwork in Shenzhen.
The desk cannot give an opinion on whether a buyer's specific goods need certification. That is a regulatory determination for the importer, an importer-side conformity body, or the buyer's legal adviser — not for a component supplier. Even a correct answer can mislead when the question is the wrong one, which is why the honest reply is to point the buyer at the right person rather than to manufacture one.
What the Desk Does Sign Off On: Commercial Documents for a Russia-Bound Order
What an independent desk does provide is the commercial layer of the shipment. The desk is the entity that buys the parts, takes responsibility for their condition, issues the commercial paperwork, and arranges the carriage under whatever Incoterm the quotation states. For an order bound for Russia or a CIS country, that paperwork is concrete and bounded.
A commercial invoice accompanies every consignment. It identifies the buyer, the seller, the line items by part description and quantity, the unit and total values, the currency, the Incoterm, and the country of dispatch. It is a transactional document, not a conformity document; nothing in it asserts that the goods are EAC-compliant, and nothing in it should be read that way.
A packing list accompanies every consignment. It itemizes the lines by part number, description and quantity, mirrors the commercial invoice line by line, and records the carton count, weight and dimensions. It is also a transactional document.
A proforma invoice is issued before the order ships, against which the buyer arranges payment. It states the same elements as the commercial invoice, with terms of payment and bank details, and it is the document the buyer's bank references when transferring funds.
A certificate of origin can be supplied where the source of the goods can actually issue one. For a new, sealed component from a documented channel, origin is generally available. For used, refurbished, or market-sourced stock, origin is often not available from the source and the desk says so rather than fabricating a certificate.
We screen end users and end uses, classify before quoting, and decline transactions that cannot be screened. That sentence belongs on every page that mentions DDP, customs clearance, or Incoterms, and it is the operational rule behind the words above — paperwork is honest, the desk's scope is honest, and the boundary between what is issued and what is not issued is not a negotiation point.
Where the Line Falls Between Supplier and Importer
The clearest way to see the boundary is to follow a single shipment through the desk and into the Union.
The desk sources the line — say a Siemens 6ES7212-1AE40-0XB0 (SIMATIC S7-1200 CPU 1212C), a 6ES7211-1AE40-0XB0 (S7-1200 CPU 1211C), or a 6ES7222-1BF22-0XA0 (SIMATIC S7-200 digital output module); or a Schneider TeSys D contactor, an Omron E3Z photoelectric sensor, or a Phoenix Contact QUINT power supply. The line is offered on the quotation with its manufacturer, part number, condition (new, new surplus, refurbished, used), price, MOQ and lead time stated per row. The desk confirms the condition, runs the pre-dispatch check on refurbished and used lines, and prepares the commercial invoice and packing list against the confirmed list.
The buyer, who is the importer of record, is responsible for the conformity side of the same shipment. That means: determining whether the goods fall inside one or more TR CU scopes, deciding which conformity procedure applies, engaging a notified body or accredited laboratory where the regulation requires it, applying for the certificate or declaration, registering the declaration where registration is required, and maintaining the technical file the regulation expects. None of those steps happen on the desk's side of the transaction, because none of them can.
Where the quotation carries the term DDP, the desk additionally arranges carriage and import clearance, paying the import duties so the goods arrive at the buyer's door with nothing further to settle. That covers logistics and duties; it does not cover conformity. A shipment can arrive DDP and still be non-compliant, and the importer remains the party that has to make it compliant — usually by holding the right EAC or TR CU paperwork before the goods are placed on the market.
Where the quotation carries DAP or EXW, import duties and import clearance remain on the buyer's side from the start. The desk's role is again limited to the parts, the documents it can evidence, and the carriage it has contracted.
The line, in short: the desk ships, the desk clears under DDP when the quotation says DDP, and the importer certifies. Mixing them is the failure mode the red lines exist to prevent.
Buying from a Sourcing Desk When the Importer Handles Conformity
For a buyer whose quality system, importer of record, or equipment manufacturer already runs the conformity procedure, working with an independent desk is straightforward.
Send the line list — part numbers, descriptions, quantities — and any alternative-part note your engineering team has provided. The desk returns a per-line quotation: price, MOQ, lead time and condition stated by row rather than blended. Where a line is obsolete or allocation-constrained, the desk reports which of the three routes — remaining channel stock, a documented equivalent listing, last-time-buy — actually applies for that line.
Confirm the order against the proforma invoice and the Incoterm on it. The Incoterm determines who clears customs and who pays duty; it does not determine who certifies conformity, and the buyer should not need it to.
Receive the consignment with its commercial invoice and packing list. Where the goods are used or refurbished, the pre-dispatch photographs and any video are part of the shipment record, and they are the basis on which condition is agreed before dispatch.
The conformity step stays with the importer. The desk is a useful source for the goods and the commercial paperwork; it is not a useful source for the certificate, the declaration, or the regulatory opinion. Treating those as separate jobs is what makes the relationship work, and what keeps both sides inside their own competence.
Two practical habits help. First, decide before ordering whether the goods fall inside a TR CU scope that requires a certificate, a declaration, or registration — the importer or the importer's adviser is the right place for that decision, and a desk that tries to make it for you is a desk that has overstepped. Second, when a quotation arrives with DDP, read the terms for what they cover (carriage plus import duty) and what they do not cover (conformity, registration, post-import surveillance) — both belong on the importer's checklist, and neither is something the desk can take off it.
What to Send When You Open an Inquiry
If a buyer wants to open a quote, three pieces of information move things fastest.
The line list, in any format: an Excel file, a PDF of the BOM, a photo of a handwritten sheet, or an ERP export. Mixed-brand lists are normal rather than exceptional, and a partial list — full BOM for an order, partial for an emergency on a down machine — is fine. The desk works the list line by line; a single line is also a list.
The condition expectation per line, where the buyer's engineering team has one. New surplus where a new-build machine is going together, refurbished where the part is going into a repair that needs documented test, used where downtime is the binding constraint and the part is going to be bench-tested on receipt.
The destination and the Incoterm expectation. Worldwide is the standard, including Moscow and the regions of the Russian Federation, and the CIS. The exact Incoterm — EXW, FCA, DAP, or DDP — is confirmed on the quotation rather than announced in advance, because it depends on the destination, the value, and the buyer's own customs arrangements. Where the buyer wants DDP, the quotation will state the term; where the buyer wants DAP or EXW, the quotation will state that instead.
The conformity work is the importer's, and the desk is the place to source the parts, document their condition, and arrange the shipment. Both jobs are easier when each side stays inside its own lane. When you are ready to open a quote, send us your BOM through the inquiry form or the /baojia quotation tool, and the desk will work it line by line with a per-row quotation, condition disclosure and pre-dispatch record on used and refurbished lines.
New Surplus, Refurbished, Used, and What the Desk Cannot Sign Off On
We are an independent distributor — not an authorized distributor of any brand — and the quotation works line by line. Condition (new, new surplus, refurbished or used) is stated per line before the buyer commits, with a pre-dispatch record for used and refurbished lines. What the desk never signs off on is the conformity side of a Russia-bound shipment: that belongs to the importer of record or the equipment manufacturer.
Data Notes: this piece, last updated in September 2026 by the China sourcing desk, draws on the desk's published shipping and terms positions, the EAEU technical regulations framework as it is generally understood in the industrial automation trade, and the line-by-line quotation practice that the desk operates against. It does not state EAEU regulatory text verbatim and is not legal advice; importers confirm the conformity procedure for their specific goods with their own advisers.
FAQ
Do you hold EAC or TR CU certification for industrial automation parts?
No. An independent China-based sourcing desk does not hold EAC or TR CU certification for the goods it supplies, and does not apply for certification on a customer's behalf. The conformity assessment for a part going into the Union market is arranged by the importer of record or the equipment manufacturer. See the sourcing desk's /shipping-returns and /about pages for the published position on this.
Can an independent China-based distributor apply for EAC on my behalf?
No. The applicant on a TR CU conformity assessment is the party with a documented presence in the Union market — usually the importer of record, the equipment manufacturer, or a notified body acting for one of them. A China-based desk sitting on the supply side of the transaction is not in that position, and any desk that claims otherwise is overstating its authority.
Who handles customs clearance into Russia when the quotation says DDP?
Under DDP (Delivered Duty Paid) the desk arranges carriage and import clearance as part of the delivery, paying the import duties so the goods arrive at the buyer's door with nothing further to settle. Under EXW, FCA or DAP, import clearance is arranged by the buyer's side and remains outside the desk's scope. The Incoterm on the quotation is the term that applies; it does not, in any case, cover conformity assessment.
Does shipping under DDP mean my goods are automatically EAC-compliant?
No. DDP covers carriage and import duty, not conformity. A shipment can arrive DDP at the buyer's door and still be non-compliant with the relevant TR CU; the importer remains the party that has to make it compliant before the goods are placed on the Union market. The desk's screening covers end-user and end-use classification, not TR CU conformity.
What documents will I receive with a shipment to Russia or the CIS?
A commercial invoice and a packing list accompany the consignment. A proforma invoice is issued before the order ships, against which payment is arranged. A certificate of origin is supplied only where the source of the goods can actually issue one, and that is confirmed line by line at quotation stage rather than promised in advance. EAC or TR CU documentation is the importer's, not the desk's, and is not issued by the desk.
Can you tell me whether a specific PLC or drive requires EAC certification?
No — and that is an honest answer rather than a refusal to help. Whether a given component or machine falls inside a technical regulation, which conformity procedure applies, and who carries the conformity obligation, depends on the product, its intended use and the rules of the importing market at the time of import. The importer or a local conformity body is the right place for that determination; the desk reports what its records and the source can evidence and points the question back to the right side.
Is shipping under DDP available for buyers anywhere in Russia and the CIS?
Delivery is worldwide rather than limited to a list of cities, so regional destinations in Russia — including Novosibirsk, Yekaterinburg and the Far East — are served on the same basis as Moscow, and the CIS on the same basis as Russia. The commercial term that applies to a specific order — EXW, FCA, DAP, or DDP — is stated on the quotation and is the term that governs the shipment; it is not announced as a general policy in advance.
