Two key KKDIK deadlines fall in 2026: 30th September and 31st December. They are only three months apart, leaving very little room to improvise.

If you place substances on the Turkish market, the rest of this year will decide whether your products can stay there. A recent notice from the Turkish Ministry (MoEUCC) made the September deadline (Provisional Registration) mandatory for every substance, every tonnage band, and every company, with no exceptions, and inspections will begin immediately after. Three months later, the first full registration deadline applies to high-tonnage substances, CMRs, and aquatic hazards.

On August 12, 2025, the  Turkish Ministry of Environment, Urbanization and Climate Change (MoEUCC) published the long-awaited Procedures and Principles (P&P) for KKDIK implementation, with a few surprises!

Affected by the KKDIK? This finalized version of the P&P brings new requirements and additional deadlines. Time to get to work!

In our post Data Sharing in the Process Industry: Rules and Principles we introduced key data sharing concepts. They are increasingly important due to the emergence of REACH-like regulations. Now, we're taking the next step: applying these concepts to the practical process of chemical registration.

With the end of 2024 approaching rapidly, companies dealing with chemical substances under K-REACH face a critical registration deadline.

There are a number of new REACH-like regulations worldwide, such as Türkiye KKDIK and Korean K-REACH. This number will most likely continue to grow. What does this mean for chemical companies?

This increase in REACH-like regulations demands not only more data, but also places a demand on sharing data among companies. For this reason, chemical companies must improve the way they manage and maintain data across regulations. A key part to efficient data management is to understand the underlying concepts of data sharing.

The deadlines for KKDIK registration have been extended. This makes it an opportune moment for businesses to evaluate their existing compliance process and strategize for the future. The extra time is valuable. It’s the best time to take proactive steps to streamline processes for registration and ensure a smoother transition.

The Regulation on Chemicals Registration, Evaluation, Authorization and Restriction (“KKDIK”) in Türkiye (Regulation No. 30105) came into force on December 23^rd, 2017. The competent authority in Türkiye is the Ministry of Environment Urbanization and Climate Change (MoEUCC).

The KKDIK Regulation established a transitional provision for registration where all substances manufactured or imported into Türkiye at 1 t/a or more had to be registered by December 31^st, 2023.
