2025 Updates in the KKDİK Regulation: A Roadmap for Companies

The Regulation on Registration, Evaluation, Authorization and Restriction of Chemicals (KKDİK) is Turkey's most comprehensive chemical legislation, aligned with the EU's REACH. It is enforced by the Ministry of Environment, Urbanization & Climate Change and imposes significant obligations on all chemical substances placed on the market or imported. As of 2025, there are essential updates for companies to watch — this article outlines the key changes and gives you a practical roadmap.

Purpose of KKDİK

• Protect human health and the environment from the adverse effects of chemicals

• Ensure the safe use of chemical substances via information flow

• Accelerate Turkey's harmonization with the EU market

• Support transparency and fair competition among companies

Key Highlights of the 2025 Updates

1. Registration Obligations & Deadlines

   • Final deadlines have been set for previously postponed registrations

   • A tiered registration approach based on tonnage ranges is implemented

2. Revised Tonnage Thresholds

   • Substances exceeding 1 ton per year now fall under registration obligations

   • For substances ≥ 100 tons, additional toxicological and ecotoxicological testing will be mandatory

3. Only Representative (OR) Regulations

   • Stricter enforcement on appointing an Only Representative for foreign suppliers

   • The obligations of Turkish importers clarified

4. Dossier Content Requirements

   • Registration dossiers, to be prepared in IUCLID format, will require more detailed exposure scenarios and risk management measures

5. Inspections & Penalties

   • Administrative fines increased for companies submitting incomplete or incorrect dossiers

   • Non-compliant companies may have restrictions placed on their market access

Roadmap for Companies

• Conduct a scope & tonnage analysis to identify substances subject to registration
