Registering a chemical substance under Turkey’s KKDIK Regulation follows a structured process. For substances manufactured or imported at 1 tonne per year or more, the key steps are: building a substance inventory and calculating annual tonnage; a pre-MBDF enquiry through the KKS system; forming or joining an MBDF with other registrants of the same substance; verifying substance sameness and sharing data; closing data gaps through testing, literature or QSAR/read-across; preparing the IUCLID technical dossier and, above 10 tonnes, a Chemical Safety Report; and submitting the joint registration via KKS. Foreign manufacturers cannot register directly and typically appoint a Turkey-based Only Representative. Registrations must be completed by 30 September 2026. ONAY Mühendislik manages the entire process end to end.
