What is the difference between EAC and GOST K/GOST UZ?

EAC is a unified certification for the Eurasian Economic Union. However, GOST K remains the national standard for specific products in Kazakhstan (especially metrology), and GOST UZ is the mandatory national certification for Uzbekistan, which is not an EAEU member.

Is GOST K mandatory for measuring instruments in Kazakhstan?

Yes. Most measuring instruments used in trade and industry require a Pattern Approval Certificate (PAC) and registration in the Kazakhstan state metrology database under the GOST K system.

How long does it take to obtain a GOST UZ certificate for Uzbekistan?

The issuance timeline for a GOST UZ certificate is typically between 3 to 7 business days for batch shipments and up to 15 days for serial production models.

What are the costs for certification in Kazakhstan and Uzbekistan?

The investment for national certification in these regions generally starts from €600. The final cost depends on the validity period, the technical complexity of the product, and required laboratory testing.

GOST K & GOST UZ Certification | Kazakhstan & Uzbekistan Compliance

CENTRAL ASIAN CERTIFICATION: GOST K & GOST UZ – Last update: 24.02.2026

As the Eurasian economic landscape evolves, the national certification systems of Kazakhstan (GOST K) and Uzbekistan (GOST UZ) have become essential for international manufacturers. While EAC covers the broader Union, these specific national marks are the key to unlocking major infrastructure projects in the CIS region. TechSert provides a dedicated “One-Stop Solution” to manage these complex registrations, ensuring your goods clear customs without delays.

1. GOST K: THE KAZAKHSTAN NATIONAL SYSTEM

The GOST K Certificate is the mandatory mark of conformity for products entering the Republic of Kazakhstan that are not yet covered by TR CU (EAC) regulations.

KEY TECHNICAL AREAS:
• METROLOGY & PAC: Measuring instruments must be registered in the Kazakhstan state database. This requires a Pattern Approval Certificate (PAC) for Kazakhstan.
• GGTN PERMIT: High-risk equipment used in the mining and oil sectors often requires a specific Permission to Use from the Kazakh industrial safety authorities.

CASE STUDY: INDUSTRIAL AUTOMATION
A global leader in flow-meter technology needed to supply a major refinery in Atyrau. While the devices were EAC certified, Kazakh law required a GOST K Metrology Certificate. TechSert managed the laboratory testing in Almaty, securing the state registry entry in under 15 days.

2. GOST UZ: ENERGY SECTOR & POWER GENERATION

Uzbekistan is undergoing a massive energy revolution, investing billions in Solar, Wind, and Gas-to-Liquids (GTL) projects. Because Uzbekistan is not an EAEU member, EAC marks are not valid here; GOST UZ remains the only legal standard.

ENERGY SECTOR REQUIREMENTS:
• ELECTRICAL SAFETY: Power transformers, switchgears, and renewable energy components must meet Uzstandard safety codes.
• EXPLOSION PROTECTION: Specialized equipment for the gas fields of the Bukhara region requires rigorous national certification.

• METROLOGY & PAC: Measuring instruments must be registered in the Uzbek state database. This requires a Pattern Approval Certificate (PAC) for Uzbekistan.

CASE STUDY: RENEWABLE INFRASTRUCTURE
An international consortium building a 500MW wind farm in the Navoi region required urgent certification for imported turbines. TechSert coordinated with Uzstandard to issue a GOST UZ Serial Certificate, allowing for continuous shipments over a 3-year period.

3. GOST UZ: THE CONSTRUCTION & BUILDING BOOM

With the Tashkent City development and nation-wide urbanization, the building sphere in Uzbekistan is one of the fastest-growing in Asia. National compliance is strictly enforced at the border.

BUILDING MATERIALS & SYSTEMS:
• STRUCTURAL COMPONENTS: Metal structures, specialized glass, and insulation materials require GOST UZ to verify fire safety and load-bearing standards.
• HVAC & ELEVATORS: Climate control systems and vertical transport for modern high-rises must pass national technical inspections.

CASE STUDY: URBAN ARCHITECTURE
A European provider of high-end curtain wall systems for a skyscraper in Tashkent faced a customs block. By utilizing our local presence, TechSert facilitated a GOST UZ Batch Certification, verifying the technical specs against local building codes in record time.

4. LOGISTICS, TIMELINES & INVESTMENT

ISSUANCE TIMELINE:
• GOST K: Typically 15–22 business days depending on laboratory availability.
• GOST UZ: 13–17 business days for batch shipments; up to 35 days for serial production.

ESTIMATED COSTS:
The investment for these certificates generally starts from €600 and can vary up to €4,500.
Factors include the validity period, the number of variants, and whether on-site factory inspection or sample testing is required by the specific technical regulation.
