KKDIK Registration for Foreign Manufacturers | Interim & Full Registration
Foreign manufacturers exporting chemicals to Türkiye must complete KKDİK registration through a Türkiye-based Only Representative. Registration has two stages: interim (pre-)registration and full registration with a complete technical dossier by 30 September 2026. ONAY Mühendislik manages both stages on your behalf.
The KKDİK registration process
First, your appointed Only Representative determines substance identity, your company role and the relevant tonnage band, then completes interim registration. Next, the full registration dossier is prepared — including physicochemical, toxicological and ecotoxicological data, exposure scenarios and, where required, a Chemical Safety Report — and submitted through the KKS system.
Data ownership and cost control
Correct handling of data ownership, letters of access and lead/member roles within the SIEF (MBDF) directly affects your registration cost. ONAY's data-mining and SAR/QSAR capability helps minimise unnecessary testing and control costs across 2.000+ lead dossiers and 14.000+ member registrations.

Frequently Asked Questions
Can a foreign manufacturer register under KKDİK directly?
No. A non-Turkish manufacturer must appoint a Türkiye-based Only Representative who registers and manages the dossier on its behalf.
What are the KKDİK registration deadlines?
By 30 September 2026 every substance in scope must hold a provisional or full registration number. Full registration itself is phased by tonnage and hazard criteria: 31 December 2026, 31 December 2028 and 31 December 2030.
Interim and full registration
Foreign manufacturers meet the Turkish requirements in two stages. Interim registration secures market access within the transition period, while full registration delivers the complete data set. Both run through an only representative established in Türkiye, since a company outside the country cannot submit directly.
What we need from you
- Signed appointment letter and company records
- Substance identity with analytical support
- Annual volumes per importer
- Existing study data or the access rights covering it
What changes for your importers
Once the appointment is in place, importers covered by it become downstream users. Their own registration duty falls away, which is often the strongest commercial argument for the arrangement. The change must be communicated in writing to each importer.
