Under Turkey’s KKDIK Regulation — the Turkish equivalent of EU REACH — companies registering the same substance must share data and cooperate through a Substance Information Exchange Forum, known locally as MBDF. After the pre-registration (pre-MBDF) stage, registrants of the same substance form an MBDF to agree on substance sameness, share existing studies, appoint a Lead Registrant and prepare a joint IUCLID dossier. This joint submission avoids duplicate testing, reduces costs and ensures a single, consistent registration per substance. Key activities include substance identity verification, data gap analysis, cost-sharing and Letter of Access (LoA) management, and coordination between lead and member registrants. Foreign manufacturers typically participate through a Turkey-based Only Representative. ONAY Mühendislik acts as Lead Registrant, manages MBDF processes end to end, and operates its own digital MBDF infrastructure to streamline data sharing and cost allocation. Registrants must complete their preliminary or full KKDIK registrations by 30 September 2026, so early engagement in the relevant MBDF is strongly recommended.
