KKDIK vs EU REACH: A Two-Way Compliance Guide

Companies supplying chemicals to both the Turkish and EU markets must comply with two separate but similar regulations: KKDIK in Turkey and REACH in the EU.

Both systems share the 1 tonne/year threshold, tonnage-based data requirements, an IUCLID dossier and the Only Representative option. The differences are the competent authority and system (KKS/Ministry vs REACH-IT/ECHA), dossier language and timeline. EU REACH registration deadlines were completed in 2018, while KKDIK follows the 30 September 2026 process.

Managing both systems together allows efficient reuse of shared data. ONAY Mühendislik manages KKDIK and EU REACH processes in parallel.
