Turkish SDS Prepared by a Certified KDU Under KKDIK

Turkish SDS for products supplied to Turkey

A Turkish SDS under KKDIK must be written in Turkish, follow Annex 2 of the KKDIK Regulation and be prepared by a certified Chemical Assessment Expert (Kimyasal Değerlendirme Uzmanı, KDU). A translated EU SDS does not meet these conditions on its own. We prepare Turkish SDSs from your existing EU or GHS sheets, adapt the Turkish-specific sections, and deliver a document your importer can pass on to customers and upload to the Ministry's system.

What a KKDIK-compliant Turkish SDS is

A KKDIK-compliant Turkish SDS (Güvenlik Bilgi Formu, or GBF) is a 16-section safety data sheet in Turkish, prepared in line with Annex 2 of KKDIK by a KDU certified under Annex 18. Its classification follows Turkey's SEA regulation, and section 16 names the KDU who prepared it, with certificate number and date.

The legal requirements for a Turkish SDS

The core rules are in Article 27 of the KKDIK Regulation, published in the Official Gazette on 23 June 2017 (No. 30105). A supplier must provide an SDS prepared under Annex 2 and by a KDU when the substance or mixture is classified as hazardous under the SEA regulation, when a substance is PBT or vPvB under Annex 13, or when it is on the candidate list. Article 27 also states that:

• the SDS is supplied in Turkish (paragraph 5);
• it is dated and contains the 16 standard headings (paragraph 6);
• it is supplied free of charge, on paper or electronically (paragraph 8);
• it is updated without delay when new hazard information, an authorisation decision or a restriction arises, and the updated version goes to every recipient supplied in the previous 12 months (paragraphs 9 and 10);
• after registration, any update carries the KKDIK registration number (paragraph 10).

Classification is made under the Regulation on Classification, Labelling and Packaging of Substances and Mixtures, known as the SEA regulation (Official Gazette of 11 December 2013, No. 28848), which is aligned with EU CLP.

The earlier Turkish SDS regulation of 13 December 2014 (No. 29204) was repealed by Article 64 of KKDIK with effect from 31 December 2023. From that date, new SDSs are prepared only under KKDIK Annex 2 and only by a KDU. According to the Ministry's Chemicals Help Desk, SDSs prepared under the old regulation remain valid until an update is triggered, but any revision must then be made by a KDU.

The KKDIK Procedures and Principles issued in August 2025 added two practical points. Suppliers upload their SDSs as PDF files to the SDS notification system in the Ministry's Integrated Environmental Information System (ECBS), and section 16 must show the KDU's contact details and the date and number of the KDU certificate.

Who a KDU is and why foreign suppliers need one

A KDU is a person certified under Annex 18 of KKDIK to prepare SDSs and to review registration information. Certification requires 64 hours of training at a Ministry-approved training body followed by an exam run by an accredited personnel certification body. The certificate is time-limited and has to be renewed.

The KDU requirement is a Turkish rule with no direct EU equivalent. Your in-house EU SDS author, however experienced, cannot sign a Turkish SDS without the Turkish certificate. This is why most non-Turkish suppliers, and many Turkish importers without in-house experts, commission the Turkish SDS from a consultancy in Turkey. Our Turkish SDSs are prepared and signed by a certified KDU.

Translation or re-authoring

We are often asked to "just translate" an EU SDS. The technical core can be reused, since KKDIK Annex 2 follows the EU Annex II structure, but several sections must be rewritten for Turkey.

A literal translation also tends to produce Turkish hazard and precautionary statements that differ from the official Turkish wording in the SEA regulation. Customers and inspectors notice this quickly. We use the official phrases and keep the Turkish version on the same revision number as your master SDS.

What Turkish customers and authorities ask for

With the 2026 KKDIK registration steps now in force, Turkish buyers of imported chemicals typically ask their suppliers for the following.

1. A Turkish SDS prepared by a KDU, with the KDU details in section 16. Many purchasing departments will not release an order without it.
2. A KKDIK registration or temporary registration number for each registrable substance, or a letter from your only representative confirming that the importer is covered as a downstream user.
3. A Turkish label that matches section 2 of the SDS, with the Turkish supplier's name, address and telephone number.

At customs, as far as we could confirm in late September 2026, no instruction had been issued requiring a KKDIK registration number on the import declaration. Customs brokers do commonly request the SDS to confirm the tariff classification and dangerous goods status of a shipment. Separately, the Ministry has said it will check after 30 September 2026 whether substances manufactured or imported in Turkey hold a temporary or full registration number. That check can reach your importer even if the goods clear customs.

Keeping the label and the SDS aligned

Under the SEA regulation, hazardous products supplied in Turkey need a Turkish label with the product identifier, hazard pictograms, signal word, hazard and precautionary statements, and the supplier's contact details. The label content must match section 2 of the SDS exactly.

When we prepare the Turkish SDS we also deliver the Turkish label text, ready for your packaging artwork or for a sticker applied by your importer. Where your EU label carries information that is not required in Turkey, or the reverse, we mark it so your packaging team can decide whether to use a combined label.

How we prepare your Turkish SDS

1. Document review, 1 to 2 days. We review your current SDS, formulation and raw material data, and confirm the Turkish supplier details.
2. Classification check, 1 to 3 days. We check classification under the SEA regulation and flag any difference from your EU or GHS classification.
3. Authoring, 2 to 5 days. The KDU prepares the Turkish SDS, rewrites sections 1, 8, 13, 15 and 16, and checks the official Turkish phrases.
4. Your approval. We send an English summary of the changes so you can approve without reading Turkish.
5. Delivery and upload. Signed PDF, Turkish label text, and upload to the ECBS SDS notification system if you or your importer ask us to.

What we need from you

• Your latest SDS in English, or in another EU language.
• Full formulation with CAS numbers and concentrations, under a confidentiality agreement if needed.
• Raw material SDSs for any ingredient whose classification we need to verify.
• Name, address and telephone number of the Turkish importer or only representative.
• KKDIK registration or temporary registration numbers, where already issued.

Turkish SDS work and KKDIK registration are best handled together, so the registration number goes into the SDS without a second revision cycle. For SDSs in other languages and markets, see our SDS authoring services. Our article on SDS requirements in Turkey covers the rules in more depth.
