High ambient temperature, sand/dust resistance, salt corrosion, strong UV radiation; electrical products must match Kazakhstan local grid voltage tolerance standards.
GOST-BY (Belarus material safety priority)
Strict additional testing for food contact materials, construction glass toxicity, indoor paint volatile organic compounds (VOC); stricter formaldehyde limits for wood furniture than Russia/Kazakhstan.
6. Mandatory Product Coverage (Goods without TR CU)
GOST-R Mandatory List
High-voltage power equipment, metering instruments, industrial steel profiles, ceramic tableware, telecom radio terminals, special industrial coatings.
GOST-K Mandatory List
Local power grid components, agricultural fertilizers, mining auxiliary materials, road construction aggregates, desert-use machinery parts.
GOST-BY Mandatory List
Domestic household chemical cleaners, building glass, welding consumables, food packaging plastic, local heating equipment.
7. Application & Audit Rules
GOST-R
Serial certificate requires annual surveillance factory audit
All lab tests must be completed in Russian Rosaccreditation-accredited labs; test reports from KZ/BY labs rejected
GOST-K
3/5-year serial certificates require annual factory surveillance audit
Accept tests from Kazakh accredited labs only; Russian lab reports not fully recognized for mandatory GOST-K
GOST-BY
Annual surveillance audit for multi-year serial certificates
Mandatory testing in Belarus local accredited laboratories
8. Administrative & Customs Policy Differences
QR trace code enforcement
GOST-R: QR code not strictly mandatory (unlike EAC)
GOST-K: Voluntary QR registry marking
GOST-BY: No official QR tracking requirement
Tender supplementary demand
GOST-K: Most state projects require voluntary GOST-K even with valid EAC
GOST-R / GOST-BY: Voluntary national cert only occasionally requested by large private buyers
Customs penalty severity
Russia imposes the highest fines (up to 20% of cargo value) for missing GOST-R on non-TR CU goods; Belarus and Kazakhstan fines are lower.
