Our Services under the KKDIK (Turkey REACH) Regulation

What is KKDIK?

The KKDIK Regulation (Registration, Evaluation, Authorisation and Restriction of Chemicals) is the Turkish adaptation of the EU REACH Regulation in line with the requirements of the Turkish industry. The aim of the KKDIK Regulation is to ensure the control of chemicals within the Republic of Türkiye.

The KKDIK Regulation entered into force on 23 December 2017 and covers the provisions on registration, restriction, and authorisation of chemical substances.

Procedures and Principles Regarding the Implementation of KKDIK

On 12 August 2025, the Procedures and Principles Regarding the Implementation of the KKDIK Regulation were published. Click here to review.

The main topics of these Procedures and Principles include pre-registration deadlines, the determination of the lead registrant, temporary registration, and the establishment of expert consultation systems.

KKDIK Deadlines

According to the Procedures and Principles, the KKDIK deadlines are as follows:

31.10.2025	Registrants must complete pre-registration and become members of the SIEF by this date. For substances manufactured and/or imported for the first time after 31.10.2025, pre-registration must be completed within 30 days after being placed on the market.
31.12.2025	Lead registrants for substances placed on the market before the publication of the Procedures and Principles must be determined by this date. For substances placed on the market for the first time after publication, the lead registrant must be determined within six months.
