KKDIK: new deadline of 30 September 2026 for the registration of substances
Following the announcement by the Turkish Ministry of the Environment, Urbanisation and Climate Change (MoEUCC) on 6 March 2026, substances manufactured or imported into Türkiye in quantities of at least one ton per year must be subject to temporary or permanent registration with the Ministry’s Chemicals Registration System (KKS) by 30 September 2026 at the latest.
Everything you need to know about the KKDIK’s 2026 deadline
KKDIK 2026 deadline: what are the obligations for businesses?
The deadline of 30 September 2026 is separate from the phased legal deadlines for obtaining definitive registration under the KKDIK (Turkish Regulation on the Registration, Evaluation, Authorisation and Restriction of Chemicals), which are set at
31 December 2026
- For substances manufactured or imported in quantities of 1,000 tons or more per year
- For substances manufactured or imported in quantities of between 100 and <1,000 tons per year and classified as hazardous to the aquatic environment (Aquatic Acute 1 and Aquatic Chronic 1)
- For substances manufactured or imported in quantities of 1 metric ton or more per year and classified as CMR Category 1A or 1B
31 December 2028
- For substances manufactured or imported in quantities of between 100 and <1,000 tons per year
31 December 2030
- For substances manufactured or imported in quantities of 1 metric ton or more per year
From 1 October 2026, regulatory inspections and supply chain audits must verify the presence of a valid provisional or definitive registration number. 30 September 2026 is therefore the regulatory deadline that must be met to ensure your products can be placed on the market.
In the absence of a valid provisional or definitive registration, the manufacture, import or placing on the market of the substance is not permitted.
Who is affected by the KKDIK deadline of 30 September 2026?
The following are affected by the KKDIK deadline:
- European manufacturers exporting substances to Türkiye,
- European formulators supplying mixtures to Türkiye,
- European poducers of articles containing substances that are to be intended to be released.
To fulfil your KKDIK obligations, you will need to appoint an Only Representative (OR). EcoMundo offers to represent you in Türkiye to ensure the continuity of your business.
How can you ensure compliance by 30 September 2026?
Temporary registration a solution to ensure compliance
Temporary registration enables companies to meet the regulatory deadline whilst allowing them extra time to finalise their dossier.
A company may also submit an individual temporary registration, even where a lead registrant has already submitted a complete dossier. For example, where there are difficulties relating to participation in joint registration, such as a disagreement within the SIEF, the absence of a lead registrant, or the cost of sharing the letter of access (LoA) being deemed excessive.
Full registration: for dossiers that are already structured
Where the company has the necessary data and is able to join or form a joint submission, a full registration is the most straightforward option. This approach helps to minimise the need for adjustments.
However, it requires a precise identification of the substance, the necessary rights to the data used, and relevant information regarding classification, uses and exposure. The dossier must also be prepared and validated with the involvement of an authorised OR.
KKDIK regulatory framework: understanding Türkiye’s REACH regulation
The Turkish KKDIK Regulation, published on 23 June 2017, requires companies that manufacture chemicals in Türkiye, as well as those that import more than one ton per year, to register them with the Turkish Ministry (MoEUCC).
The aim of this regulation is to improve the efficiency, transparency and reliability of the chemical registration process in Türkiye.
Like REACH, the KKDIK is based on the principle of ‘one substance, one registration’, which involves joint registration.
Suppliers’ obligation to notify
Under Article 24 of the KKDIK Regulation, registrants acting as only representatives of manufacturers or formulators established outside Türkiye must inform the national suppliers designated by those manufacturers, in particular the relevant Turkish importers.
The notification must specify, in particular, the substances and dossiers registered under the KKDIK, the associated registration numbers, their compliance status and any applicable restrictions or conditions. This obligation is intended to ensure that importers have the necessary information to ensure that their activities comply with the Regulation.
The companies concerned must also ensure that their Safety Data Sheets (SDS) comply with the requirements of the KKDIK. In particular, safety data sheets must be available in the required format and language and must include information identifying the certified professional responsible for their authoring or updating.
What needs to be done before September 30, 2026?
- Identify the concerned substances and check the quantities.
- Check the registration status of each substance.
- Determine the registration strategy: joint, provisional individual or full.
- Secure the supply chain and verify compliance with obligations relating to safety data sheets, notification and the OR.
