On 12 August 2025, the Ministry of Environment, Urbanisation and Climate Change (MoEUCC) announced new implementation procedures for Türkiye’s KKDİK Regulation—the country’s REACH-equivalent framework governing the registration, evaluation, authorisation, and restriction of chemicals. The new procedures introduce a phased model to streamline compliance and bring Türkiye’s chemical legislation in line with European Union standards.
This policy development has direct implications for chemical manufacturers, importers, downstream users, and value-chain operators across industrial sectors. Professionals must now plan for key registration deadlines in 2025 and 2026 or risk losing market access.
Phased Compliance Through the KKS Portal
The revised framework requires companies to register substances via Türkiye’s Chemical Registration System (KKS). In a departure from traditional approaches, the MoEUCC has introduced a phased registration model, enabling initial submission of core safety and use data without full toxicological detail.
By allowing staggered data entry, the Ministry aims to reduce disruption in the production and import of chemicals, while ensuring timely progress towards full compliance.
The required core data includes:
- Substance identity and composition
- Use scenarios and estimated quantities
- Physicochemical properties
- Safety Data Sheets (SDS)
Companies that cannot submit full dossiers by the 31 March 2026 deadline must file a provisional registration. Those completing full registration by this date are exempt.
KKDİK Deadlines to Watch
MoEUCC has outlined four critical dates:
- October 2025 – Pre-registration deadline
- December 2025 – Lead registrant selection
- March 2026 – Deadline for provisional registration
- September 2026 – Member dossier submission
These requirements apply to all actors placing substances on the Turkish market above threshold volumes, not just manufacturers. Distributors, formulators, and importers must also comply or face enforcement consequences.
Institutional Support and Sectoral Impact
To support implementation, the government is establishing two advisory bodies:
- A Chemicals Science Group of academic experts
- A Chemicals Advisory Group to guide registration decisions where data gaps remain
The policy arrives at a critical moment. The chemicals sector is Türkiye’s second-largest exporter, worth $30.8 billion, and its largest importer, at $45.3 billion. A more predictable regulatory environment is expected to improve compliance, foster safer chemical use, and protect both public health and trade competitiveness.
