If you’re looking for clear information about the documents required for an HYB Certificate, this guide provides a practical overview of the application requirements and how to prepare.
The documents required for an HYB Certificate vary depending on your business activity and the applicable Turkish Standards Institution (TSE) service standard. Preparing only a general checklist is usually not sufficient. The services your company provides, technical personnel, workplace conditions, equipment, and service records are all evaluated together during the certification process.
An HYB Certificate demonstrates that a business is capable of providing its services in accordance with the relevant standard. Therefore, the required documents verify not only the legal status of the company but also its ability to consistently deliver the service.
The application process begins with documents confirming the legal status of the company.
Typical company documents include:
Tax Registration Certificate
Trade Registry Gazette
Signature Circular
Chamber of Commerce Registration Certificate
Certificate of Business Activity
Authorized Representative Information
Company Address and Contact Information
All documents should be current and accurate. Outdated, incomplete, or inconsistent documents may delay the application. In particular, the company’s registered business activities should match the service area covered by the HYB application.
The suitability of the workplace is also assessed during the certification process. Documents demonstrating the business premises and operating conditions should therefore be prepared.
These may include:
Business License
Lease Agreement or Title Deed
Proof of Business Address
Facility Layout (where applicable)
Technical Compliance or Safety Reports
For businesses providing maintenance, repair, filling, installation, or technical services, the physical condition of the workplace is especially important. Inspectors may evaluate the workspace layout, equipment arrangement, and workplace safety conditions.
The HYB Certificate evaluates not only the workplace but also the qualifications of the personnel delivering the service.
Common personnel documents include:
Social Security (SGK) Employment Records
Job Descriptions
Training Certificates
Professional Qualification Certificates
Technical Staff List
Internal Personnel Assignment Records
The exact requirements vary by industry. For example, companies servicing fire extinguishers may require more extensive technical training documentation, while computer service providers may be expected to maintain detailed technician responsibilities and service records.
Businesses must also demonstrate that the equipment used to provide their services is appropriate, operational, and properly maintained.
Depending on the service provided, documentation may include:
Equipment Inventory
Equipment Maintenance Records
Calibration Certificates for Measuring Instruments
Test Equipment Records
Where calibration is required, certificates should be valid and up to date. Expired or missing calibration records may result in nonconformities during the inspection.
Service documentation is an important part of the HYB evaluation because it demonstrates that services are performed in a documented and traceable manner.
Typical records may include:
Service Report Forms
Fault Acceptance Forms
Maintenance Records
Customer Delivery Forms
Work Order Forms
Service Tracking Logs
These documents help demonstrate that the business operates through a consistent and controlled service process.
The documents required for an HYB Certificate extend well beyond standard company paperwork. Inspectors also evaluate workplace conditions, personnel competence, technical equipment, and service documentation as part of the certification process.
Preparing complete and up-to-date documentation helps ensure a smoother inspection and reduces the likelihood of nonconformities during certification.

The required documentation is particularly important for service businesses seeking to demonstrate technical competence, organized record-keeping, and service reliability.
Before submitting an application, businesses should review their service scope, the applicable TSE standard, workplace conditions, personnel qualifications, equipment, and service documentation.
Whether an HYB Certificate is mandatory depends on the company’s industry, tender requirements, customer expectations, and applicable sector regulations. Businesses should evaluate the requirements based on their specific activities.
Choosing the correct TSE standard, preparing the required documentation, and conducting a pre-inspection review can significantly improve the efficiency of the certification process. Professional guidance helps businesses identify potential gaps before the official inspection and prepare for a successful HYB application.
