KKDİK — Türkiye’s Regulation on the Registration, Evaluation, Authorisation and Restriction of Chemicals, often called “Turkey REACH” — requires every chemical substance manufactured in or imported into Türkiye at one tonne or more per year to be registered. Foreign companies cannot register directly; they must act through a Türkiye-based Only Representative. ONAY Mühendislik is a Türkiye-based chemical regulatory consultancy providing end-to-end KKDİK, REACH, MBDF, SDS and UFI/PCN services since 2010.
What does KKDİK compliance involve?
KKDİK compliance is far more than data entry into the KKS system. It covers substance identity, tonnage banding, company role determination, data ownership and access, registration strategy, technical dossier preparation and audit-evidence management. The full registration deadline is 30 September 2026.
