KKDİK is Turkey's core chemical regulation, based on the EU's REACH Regulation, covering all companies that manufacture or import 1 tonne or more of a substance per year in Turkey. The registration obligation covers not only substances on their own, but also substances in mixtures and, under certain conditions, substances in articles.
Registration timeline (tiered by tonnage and hazard)
- 31 December 2026: substances of 1,000 t/year and above; also CMR Cat. 1A/1B substances above 1 t/year and Aquatic Acute/Chronic 1 (H400, H410) substances above 100 t/year
- 31 December 2028: substances between 100 – 1,000 t/year
- 31 December 2030: substances between 1 – 100 t/year
For interim registration, the deadlines are 31 March 2026 for lead registrants and 30 September 2026 for member and individual registrants.
Our Scope
- Substance inventory mapping and registration strategy determination (lead / member / individual registration)
- Managing pre-SIEF and SIEF (Substance Information Exchange Forum) processes
- Preparation of interim and full registration dossiers in IUCLID format
- Submission to the Ministry via the Chemical Registration System (KKS) and follow-up
- Managing data-sharing and joint-submission negotiations
- Preparation of a Chemical Safety Report (CSR) for registrations above 10 t/year
How the process works
Inventory and status analysis
We map the substances, tonnages and roles in your portfolio and determine the applicable registration tier for each substance.
Strategy and cost plan
We present a roadmap covering lead/member registration options, data-sharing costs and the timeline.
Dossier preparation
We compile physicochemical, toxicological and ecotoxicological data and design the strategy for missing data (read-across, QSAR, testing).
Submission and follow-up
We submit the dossier via KKS, manage the Ministry's feedback and finalize your registration.
