As of 2026, the choice is very clear: you almost certainly need TR CU (EAC) certification.
The old Russian GOST system has been largely phased out and replaced by the unified Eurasian Economic Union (EAEU) system. Here is a quick breakdown of the two and why TR CU is the current standard:
🛡️ TR CU Certification (The Modern, Mandatory Standard)
TR CU (Technical Regulations of the Customs Union) is the current, unified mandatory certification for the entire Eurasian Economic Union, which includes Russia, Belarus, Kazakhstan, Armenia, and Kyrgyzstan.
One Certificate, Five Markets: A TR CU certificate allows your product to clear customs and be sold freely across all five member countries.
Full Replacement: Since 2013, TR CU has officially replaced the old national GOST system for the vast majority of products. If your product falls under the EAEU's Technical Regulations, a TR CU certificate is the only valid document for market access.
📜 GOST Certification (The Legacy System)
GOST 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 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 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:
TR CU is Mandatory: The old GOST certification path for the EAEU market officially expired at the end of 2025. Starting January 1, 2026, TR CU certification is the strictly enforced mandatory path.
Customs Rejection: Russian customs will reject shipments that try to use old GOST certificates for products that require TR CU.
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 TR CU 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.
