On 12 August 2025, the Turkish Ministry of Environment, Urbanization and Climate Change officially released the finalised Principles and Procedures for the KKDIK Regulation. This long-awaited update introduces several important changes that will significantly impact how companies manufacture, import, and register chemical substances in Türkiye.
The KKDIK regulation aims to align national chemical management with EU REACH standards, and this latest publication provides much-needed clarity on registration processes, deadlines, and compliance expectations.
Key changes:
Pre-registration: The updated deadline is 31 October 2025
All substances subject to KKDIK registration (≥1 tonne/year) must be pre-registered in the Chemical Registration System (KKS) by this date. Pre-registration is essential for joining the Substance Information Exchange Forum (SIEF) and progressing toward full registration.
Lead Registrants
For a substance already on the market, a Lead Registrant must be appointed to coordinate data sharing and submit the joint registration dossier. While selection is voluntary, if no company steps forward, the Ministry may appoint one based on tonnage band, available data, and company size.
In relation to existing substances already on the market, the deadline to appoint a Lead Registrant is 31 December 2025.
For new substances placed on the market after this date, a Lead Registrant must be appointed within 6 months of market placement.
Temporary Registrations
This is a newly introduced compliance pathway for companies unable to submit full registration dossiers by the initial deadlines. It allows continued market access while full data is being prepared and is subject to the same registration fees as full registration. The deadlines for submitting a temporary registration are as follows:
- Lead Registrants – 31 March 2026
- Member Registrants – 30 September 2026
Companies that submit full registration by 31 March 2026 are exempt from temporary registration requirements.
SDS Uploads Now Mandatory via the Ministry’s System
Safety Data Sheets (SDS) must now be uploaded to the Ministry’s designated SDS software platform. Each SDS must include the contact details and certification number/date of a certified Chemical Assessment Expert (KDU). This digital requirement enhances traceability and regulatory oversight.
New Advisory Groups to Support Implementation
The Ministry has established multi-stakeholder advisory groups, including the Chemicals Advisory Group, to guide policy development, resolve technical issues, and ensure alignment with international standards. These groups will meet regularly to support the effective implementation of KKDIK.
What does this mean for businesses?
If you are producing or importing chemicals into Türkiye, these changes may affect your registration strategy, timelines, and data requirements. It’s essential to:
- Review your substance inventory and registration status
- Determine whether full or temporary registration is appropriate
- Ensure SDSs are compliant and uploaded correctly
- Monitor updates from the Ministry and advisory groups
