Is a Safety Data Sheet (SDS) mandatory in Turkey?
Yes. For substances and mixtures classified as hazardous — and for certain other substances under specific conditions — a Safety Data Sheet (SDS) must be prepared and supplied down the supply chain in Turkish. The SDS is a standardised 16-section document covering the product’s hazards, safe use, transport, storage and emergency measures, and it reflects classification and labelling under the SEA (CLP) Regulation. Where required, an extended SDS (eSDS) with exposure scenarios is provided. Preparing accurate, up-to-date and compliant SDSs is both a legal obligation and essential for occupational safety. ONAY Mühendislik provides SDS authoring and updating services.

Yes, and it must be in Turkish
Any hazardous substance or mixture placed on the Turkish market must be accompanied by a safety data sheet written in Turkish. The document follows the sixteen-section structure and must be prepared under the supervision of a certified expert. Translating the European version is not sufficient.
What certified supervision means
The classification has to follow Turkish rules and cite Turkish legal references. A certified preparer signs off the document. Literal translations of EU sheets, complete with EU-only references, are one of the most frequent findings during market surveillance.
When it must be updated
- The formulation changes
- The classification of an ingredient changes
- New hazard information becomes available
- Exposure scenarios are added or revised
- Regulatory references are amended
Consistency with the label
The classification in the sheet, the pictograms on the label and the data in the registration must all agree. Where they diverge, the inspector treats the file as unreliable, so generating all three from one data source is the safest approach.
