The Turkish Standards Institution (TSE) is Turkey's sole official standards-development and certification body, established in 1960. TSE certificates are recognized as an important quality seal, particularly in domestic manufacturing, public procurement and the retail sector. TSE has developed more than 50,000 standards and publishes the Turkish equivalents of international standards (ISO, EN, IEC). For most organizations operating in the manufacturing sector, a TSE certificate is a critical tool for rapid entry into the local market and for compliance with technical specifications in public tenders.
Main TSE Certificate Types
| Certificate | Scope | Validity |
|---|---|---|
| TSE Quality Certificate | Product compliant with a Turkish standard | 1 year, renewable |
| TSEK Certificate | Criteria conformity for products with no existing Turkish standard | 1 year |
| TSE-EN Certificate | Certification based on EU-harmonized standards | 1 year |
| TSE-ISO Certificate | Certification based on ISO standards (e.g. ISO 9001) | 3 years |
| TSE Service Competency | Competency certificate in the service sector | 1 year |
| TSE Production Competency | Competency of a production facility in terms of infrastructure, equipment and human resources | 1 year |
| CE Marking (Notified Body) | Compliance with EU directives | Per EU directives |
Process Stages
- Application: A request for the relevant certificate type is submitted to TSE through an electronic application.
- Document review: TSE reviews the technical documentation of the product or service.
- Sample testing: For products, conformity tests are carried out in TSE laboratories or accredited test laboratories.
- Production site audit: TSE auditors inspect the facility on site and assess its production and quality control capability.
- Certificate issuance: If all stages are completed successfully, the certificate is issued and recorded in the TSE database.
- Periodic surveillance: Annual surveillance audits (every six months for certain certificates) are conducted throughout the certificate's validity period.
TSE Certificates in Public Tenders
In tenders held under the Public Procurement Law, technical specifications frequently include a TSE certificate requirement. Particularly for construction materials, cables, electrical appliances, food products and the service sector, suppliers without a TSE certificate cannot participate in the tender. This makes the TSE certificate not a preference but a commercial necessity.
The TSE certificate is the gateway to the public and domestic markets. It often appears as a technical requirement of tender specifications, and those who lack it are excluded from a significant part of the market.

Frequently Asked Questions
- What is the difference between a TSE certificate and CE marking?
TSE verifies conformity to Turkish standards and is aimed at the Turkish market. CE marking is a declaration of conformity with EU directives and is mandatory for export to the EU market. The two certificates serve different scopes and are not interchangeable.
- Does TSE itself carry out the audits, or do accredited bodies?
For the TSE Quality Certificate and TSEK, TSE conducts the audits directly. For management system certificates such as ISO 9001, TSE is one of the accredited certification bodies; however, other accredited bodies (TÜV, Bureau Veritas, SGS) can also issue these certificates.
- How is the cost of a TSE certificate determined?
It varies according to certificate type, product complexity and facility size. The typical cost of a TSE Quality Certificate (testing + audit + certificate) ranges between TRY 20,000 and 80,000. Periodic renewal costs are around 30-40% of the initial certificate.
