Detailed Analysis of Uzbekistan's O‘z DST Certification: Legal Basis, Scope of Application, Certification Process, and Latest Policy Updates
I. Nature and Scope of Certification
Certification Types
Mandatory Certification: Applies to high-risk products (e.g., electrical appliances, machinery, building materials, chemical products, children's products, etc.), which must pass O‘z DST standard testing and obtain a GOST-UZB certificate to clear customs.
Voluntary Certification: Non-mandatory products (such as certain decorative items and low-risk industrial goods) may apply for certification to enhance market competitiveness.
Applicable Standards
Based on Uzbekistan National Standards (O‘z DST), certain sectors adopt Eurasian Economic Union Technical Regulations (TR CU) or international standards (e.g., IEC 60335).
Typical test items: electrical safety, electromagnetic compatibility (EMC), mechanical strength, chemical composition (e.g., RoHS), energy efficiency, etc.  
II. Certification Process and Key Steps  
Document Preparation  
Application form (Russian/Uzbek), business license (notarised translation required), product technical documents (manuals, drawings), test reports (existing CE/EAC reports may simplify the process), importer authorisation letter.
Sample Testing  
Samples must be sent to an accredited laboratory in Uzbekistan (e.g., institutions under UZSTANDARD) or an internationally recognised laboratory (ILAC member). The testing cycle takes 20–45 working days.  
Factory Audit (for certain products)  
High-risk products (e.g., pressure vessels, medical devices) require on-site audits of production conditions and quality management systems (e.g., ISO 9001).
Certificate Issuance
Valid for 1-5 years, with regular surveillance audits required. Some low-risk products may only need to submit a Declaration of Conformity (DoC).
Labeling Requirements
Products must be affixed with the GOST-UZB mark, and label information must be in Russian or Uzbek.
III. Special Circumstances and Policy Updates
Simplified Process
Products already holding EAC certification (TR CU) may be exempt from certain tests, but still require registration in Uzbekistan.
Starting in 2025, certain products must include a QR code label linking to the Uzbek federal database.
Single-batch GOST-UZ Certification
Specific products (e.g., machinery, food) must be inspected for quality, quantity, and packaging by an authorised institution (e.g., Shanghai Jinghe Industry) prior to shipment, with each shipment requiring inspection.
Fees and Timelines
Certification fees for mechanical products range from approximately 3,000 to 8,000 USD, with a timeline of 4 to 8 weeks;
IV. Common Questions and Recommendations
Language and Document Format
Technical documents must be in Times New Roman font (size 10 or larger), and translations must be notarised.
Non-compliance Risks
Uncertified products may be seized by customs, with fines up to 200% of the product value.
