If you export construction machinery parts to Kazakhstan, Russia, Belarus, Kyrgyzstan, or Armenia, one document determines whether your container clears customs in days or sits in a bonded warehouse for weeks: the EAC certificate or declaration (TR CU).
The five EAEU member states — Kazakhstan, Russia, Belarus, Kyrgyzstan, Armenia — operate a single technical regulation system. A product that meets a TR CU technical regulation gets the EAC mark and can circulate freely across all member states. No national certification required per country.
The practical numbers matter:
For a typical container of mixer truck reducers and hydraulic pumps worth $30,000–80,000, the certification cost is usually $800–3,000 — less than two days of demurrage at the border. Yet most Chinese exporters get this wrong because they assume "one certificate per shipment" or confuse EAC with the old national GOST system.
This guide covers which regulations apply to your parts, certificate vs. declaration, the exact process, costs, timelines, and the mistakes that cause rejections.
There is no single "EAC certificate for machinery." The applicable technical regulation depends on the product. For construction machinery parts, four regulations cover 95% of what you will ship:
| TR CU Regulation | Scope | Typical Parts Covered |
|---|---|---|
| **TR CU 010/2011** | Machinery and equipment safety | Mixer truck reducers, hydraulic pumps and motors, gearboxes, axles, transmissions, attachments |
| **TR CU 018/2011** | Wheeled vehicle safety | Parts fitted to road vehicles: lighting, mirrors, brake components, suspension parts, wheels |
| **TR CU 004/2011** | Low-voltage equipment | Electric motors, control panels, chargers, inverters |
| **TR CU 020/2011** | Electromagnetic compatibility | Electronic control units, sensors, monitoring systems |
TR CU 010/2011 is the one that applies to most construction machinery parts. If your part is a mechanical or hydraulic component installed on an excavator, loader, mixer truck, or bulldozer, it falls under the machinery safety regulation.
Important nuance: parts sold as spare parts for repair often fall into a gray zone. Customs in Kazakhstan and Russia routinely request EAC documentation for:
Two categories are usually exempt from mandatory certification:
Do not rely on the exemption argument without documentation. Customs officers apply the regulation list, not your opinion. If in doubt, certify — the cost of certification is a rounding error compared to a border rejection.
This is where most exporters lose time and money. The EAEU system has two conformity documents, and they are not interchangeable:
For TR CU 010/2011, machinery parts such as reducers, hydraulic pumps, and gearboxes typically use certification schemes 1c (serial production) or 3c (batch) — meaning a CoC, not a DoC. However, some components can use declaration schemes. The certification body determines which applies, and an experienced Russian or Kazakh certifier will guide you.
Practical rule: budget for a CoC with factory inspection for serial production (1–3 years validity), or a batch certificate for a single shipment. Batch certification costs less but must be repeated for every new shipment.
Send the certifier: product photos, technical passport, HS code, brand, model list, and description of use. They confirm which TR CU regulation applies and which scheme (serial/batch).
For most machinery parts this is a mechanical/electrical safety test per the regulation's annexes. Testing typically takes 10–25 working days. Tests for TR CU 010/2011 cover: mechanical strength, guarding, electrical safety, noise, and the documentation package (user manual in Russian!).
For scheme 1c, the certification body audits your factory — usually remotely (video audit) or via an in-country agent. They verify production control, quality system, and traceability. Remote audits are common since 2020 and cost $300–800 on top of the base fee.
The certificate is registered in the FGIS registry (fsa.gov.ru / EAEU registry), and you receive a physical certificate with a QR code. Customs checks validity against the registry online — a paper document without registry entry is worthless.
Apply the EAC mark to the product, packaging, and accompanying documents before shipment. The mark must be legible, permanent, and accompanied by the certificate number.
Total realistic timeline (serial production): 3–6 weeks from sample dispatch to registered certificate. Batch: 2–4 weeks.
Realistic cost (2025–2026, via Russian or Kazakh certification bodies):
| Item | Serial CoC (1–3 yr) | Batch CoC | DoC |
|---|---|---|---|
| Testing (typical) | $500–1,500 | $500–1,500 | $300–800 |
| Factory audit (if any) | $300–800 | — | — |
| Certification body fee | $800–2,000 | $500–1,200 | $100–400 |
| **Total typical** | **$1,600–4,300** | **$1,000–2,700** | **$400–1,200** |
These are typical ranges for machinery parts; final quotes depend on the number of models and the laboratory workload.
The certification body will request a standard package. Prepare these in advance — missing documents are the #1 cause of delays:
Contract manufacturer's tip: if you are an OEM supplier, the brand on the certificate matters. Certify under the brand your buyer will import. Some buyers in Kazakhstan and Russia have their own EAC certificates and only need your technical documentation — ask your buyer first, because re-certifying under your name when the buyer already holds a certificate is wasted money.
Based on rejection patterns at Khorgos, Dostyk, and Moscow customs posts:
The certificate lists "concrete mixer reducers" but your invoice says "hydraulic pump." Customs checks the HS code and product description match. Fix: make the certificate's product scope broad enough ("gearboxes and hydraulic equipment for construction machinery") or issue separate certificates.
The certificate exists, but the mark is not on the physical goods. Customs can treat this as uncertified product. Fix: mark every unit, not just the packaging — most customs officers check the goods, not the boxes.
The paper certificate was issued, but the registry entry is not visible yet (or the certifier used a non-registered body). Fix: verify the certificate number in the FGIS/EAEU registry before shipping. Ask the certifier for the registry link.
Serial certificates are valid 1–5 years; customs rejects expired ones outright. Batch certificates expire with the batch. Fix: set a renewal reminder 3 months before expiry — re-certification for serial production usually does not require full re-testing.
The EAEU importer (your buyer or your buyer's agent) must be named correctly on the certificate. If your buyer changes legal entity, the certificate must be reissued or amended. Fix: confirm the exact importer legal name and INN/BIN before ordering the certificate.
A common confusion: Russian GOST certificates. Since the EAEU technical regulation system took over, GOST-R certificates for machinery parts have been replaced by EAC (TR CU) documents for regulated products. If a supplier or broker offers you a "GOST-R certificate" for a TR CU-regulated product, it is either outdated, or it is a voluntary GOST certificate that does not satisfy customs requirements.
Exceptions where national rules still matter:
Practical takeaway: for machinery parts, one EAC certificate or declaration per product range is what your buyer needs. Anything labeled "GOST-R" for these products is a red flag — either the seller does not know the current rules, or they are selling you a voluntary certificate that customs will not accept.
There are two viable strategies — and they depend on who your buyer is.
Strategy A: You certify (recommended for distributors and repeat exporters)
Strategy B: Buyer holds the certificate
When Strategy B fails: if your buyer's certificate lists a different manufacturer or model, customs rejects the shipment, and the buyer may blame you for "non-conforming goods." Get the certificate details in writing before you ship.
Reality check: a Chinese factory exporting to multiple EAEU buyers should certify once in its own name. At $1,600–4,300 for a 1–3 year serial certificate, the payback is one shipment of parts.
The EAEU market has hundreds of "certification centers," and quality varies wildly. Signs of a reliable partner:
Red flags:
Q: My buyer says "no certificate needed for spare parts." Is that true? A: Sometimes, but do not rely on it. Customs in Kazakhstan and Russia increasingly request EAC documents for hydraulic, transmission, and electrical parts. Get the exemption in writing from the buyer's broker, or certify.
Q: Can one certificate cover multiple products? A: Yes. A serial certificate can cover a product group (e.g., "gearboxes and hydraulic pumps for construction machinery") with a list of models. Adding models later may require supplementary testing.
Q: Does the certificate need to name my company as manufacturer? A: It names the manufacturer (you) and the importer (your buyer or their agent). Both must be correct on the document.
Q: I ship to Kazakhstan only. Do I need a separate certificate for Russia? A: No. EAC certificates are valid across all EAEU member states. One document covers Kazakhstan, Russia, Belarus, Kyrgyzstan, and Armenia.
Q: How long does the EAC mark stay valid on my products? A: The mark is tied to the certificate. When the certificate expires, remaining stock must be covered by a new certificate or declaration before import.
Q: What happens if I ship without EAC and customs rejects it? A: Options: return the goods (you pay freight both ways), destroy (you pay), or apply for certification at the border — which takes weeks and costs more, with no guarantee. Prevention is cheaper in every scenario.
One certified product range, one mark, five markets. Get the EAC right, and the Kazakhstan, Russia, and Kyrgyzstan buyers you contact will take you seriously from the first email — because most Chinese suppliers still cannot produce a valid certificate when asked.
