GOST-R / GOST-K / GOST-BY (GOST-B) Full Comparison Guide
Core Background
GOST originally meant Soviet national standards. After the USSR collapsed, each EAEU member created its own national GOST certification system for goods not covered by unified TR CU / EAEU regulations.
Critical Golden Rule (2026 All Countries Customs Rule)
If your product falls under any TR CU Technical Regulation → EAC is mandatory, any national GOST (R/K/BY) will be rejected by customs.
Only products with no applicable TR CU rules need the corresponding national GOST certification for that single country.
GOST-R / GOST-K / GOST-BY are NOT mutually recognized:
GOST-R only works for Russia; GOST-K only for Kazakhstan; GOST-BY only for Belarus. You cannot use one country’s GOST to clear customs in another EAEU nation.
