A significant development has taken place in KKDIK registration processes. The Ministry of Environment, Urbanisation and Climate Change shared an official letter on 4 March 2026 stating that, due to difficulties in determining the lead registrant, interim registration processes may also be carried out individually. The subsequently published "KKDIK Individual Interim Registration Flowchart" provided important operational details on how this process is to be implemented in practice via the Chemical Registration System (KKS).
This development is a notable turning point for manufacturers and importers who want to meet their KKDIK obligations on time but face bottlenecks in joint submission or lead registrant determination. The process now appears not only as a theoretical option but as a defined application route with concrete system steps.
Why is this update important for KKDIK registrants?
The Ministry held Chemicals Advisory Group meetings to run KKDIK registration processes more quickly and effectively. Because of problems in determining the lead registrant, it was decided that running interim registration processes individually in Turkey would be a fast and effective solution. This step matters not only from a regulatory angle but also as a coordination and registration strategy issue.
What does individual interim registration mean in practice?
Individual interim registration will be made via the Ministry's Chemical Registration System (KKS), with the justification clearly stated. Especially for substances whose pre-MBDF has been submitted, this route offers an alternative for companies stuck at the lead registrant or joint submission stage. This option is not an automatic simplification; it is a controlled process that requires technical preparation. The deadline for individual interim registrations is 30 September 2026.
How does the KKS workflow operate step by step?
The process follows: KKS > Substance Management > Topic: Registration > relevant substance > Go to substance. Select "KKDIK Interim Registration" from the templates and fill in the defined sections. On the Submit substance screen, set Registration type to "KKDIK Interim Registration" and select "No" in "I am applying jointly". Verify that the revolving fund fee generated by the system is consistent with the tonnage entered in Section 1.1. Complete the steps Forward > Submit substance. After submission, an application-specific payment reference number is generated. Initially "Payment made: No" is shown. Make the payment to the bank using the reference number. Afterwards, ensure the payment information is transferred to KKS by clicking again on the relevant substance in the Submitted substances screen. When "Payment made: Yes" is displayed, the dossier is taken into Ministry evaluation. If data is missing, registration may be made with a justification; supporting documents are uploaded to section 13.2 Other Assessment Report. The Chemical Assessment Expert Certificate is also added to section 13.2.
What should companies watch for in payment and documentation?
Only making the bank payment is not enough; after payment, the payment must be reflected in KKS via the Submitted substances screen. Until "Payment made: Yes" appears, the process cannot be considered complete. If data is incomplete, justification must be managed in a disciplined way; supporting documents and the Chemical Assessment Expert Certificate must be uploaded to the appropriate section.
How should businesses prepare before 30 September 2026?
Pre-MBDF status, tonnage verification, registration strategy and joint submission bottleneck analysis should be done early. Document set and payment plan should be clarified; waiting until close to the deadline can create risk due to tonnage verification, missing documents, internal coordination, supply chain communication and system load. Technical documentation and regulatory strategy should be set up early.
Pier Compliance assessment
This development can provide important relief for companies facing lead registrant determination issues. It does not mean the process has become easier; technical preparation, tonnage control, data and document strategy and dossier structure still require care. Strategy, dossier structure, document management and system follow-up remain critical.
