For exporting goods to Russia in 2026, the short answer is: you almost certainly need the EAC certificate.
The old Russian GOST-R certificate has been largely phased out and replaced by the unified Eurasian Economic Union (EAEU) system. Here is the clear breakdown of the two and why EAC is the standard today:
🛡️ EAC Certificate (The Modern, Mandatory Standard)
EAC (Eurasian Conformity) is the current, unified mandatory certification for the entire Eurasian Economic Union, which includes Russia, Belarus, Kazakhstan, Armenia, and Kyrgyzstan.
One Certificate, Five Markets: An EAC certificate allows your product to clear customs and be sold freely across all five member countries.
Full Replacement: Since 2013, EAC has officially replaced the old national GOST-R system for the vast majority of products. If your product falls under the EAEU's Technical Regulations (TR CU / TR EAEU), an EAC certificate is the only valid document for market access.
📜 GOST / GOST-R Certificate (The Legacy System)
GOST-R was Russia's old national certification system. While it was the standard for decades, it is now considered a legacy system.
Very Limited Use: Today, GOST-R is only used for a very small list of products that are not yet covered by any EAEU technical regulations, or for specific national requirements like fire safety.
Voluntary Use: Many companies still get a voluntary GOST-R certificate just to prove higher quality and boost their brand reputation with Russian buyers, but it is no longer the primary legal requirement for customs.
⚠️ Critical 2026 Compliance Update
As of 2026, the transition is complete and enforcement is strict:
EAC is Mandatory: The old GOST-R certification path for the EAEU market officially expired at the end of 2025. Starting January 1, 2026, EAC certification is the strictly enforced mandatory path.
Customs Rejection: Russian customs will reject shipments that try to use old GOST-R certificates for products that require EAC.
In summary: Unless your product is on a highly specific, rare exception list that falls completely outside of EAEU regulations, you should focus entirely on obtaining the EAC certificate (either a CoC or a DoC, depending on your product's risk level). This is the only "passport" that will legally get your goods into Russia and the surrounding Eurasian market in 2026.
