The 30 September 2026 KKDIK deadline has passed. Every registrable substance now needs a Provisional or Full Registration Number to stay on the Turkish market. The next keydate is only eight weeks away: 31 December 2026, the first full registration deadline for high-tonnage and high-hazard substances.
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!
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 23rd, 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 31st, 2023.
