About KKDIK

Under the KKDIK Regulation published on June 23, 2017 (Official Gazette 30105), companies manufacturing or importing substances in Türkiye with an annual quantity of 1 ton or more are required to complete Full Registration. Non-Turkish companies must appoint an Only Representative (OR) located in Türkiye. Registrations are carried out through the Chemical Registration System (KKS) within the Integrated Environmental Information System (ECBS).

Tonnage Bands

• ≥ 1 - 10 tons / year
• ≥ 10 - 100 tons / year
• ≥ 100 - 1000 tons / year
• ≥ 1000 tons / year

KKDIK Compliance Process — Two Stages

1) Substance Pre-registration

Pre-registration informs the Ministry about your company’s intent for full registration. Companies that pre-register join the Substance Information Exchange Forum (SIEF/MBDF). Each substance has a Lead Registrant who submits the initial file, while others become Joint Registrants.

Estimated Costs (Pre-registration):

• I. Only Representative appointment fee (ChemRAS)
• II. Pre-registration fee (ChemRAS)
• III. Annual monitoring fee until full registration (ChemRAS)
• IV. Hourly consultancy if needed (e.g. research, inventory)

2) Substance Full Registration

Full registration is the final stage and requires more time and costs.

Estimated Costs (Full Registration):

• I. Preparation of registration dossier (ChemRAS, varies)
• II. Data access fees (paid to Lead Registrant/test owner)
• III. Registration fee (paid to the Ministry, depends on tonnage/company size)
• IV. Hourly consultancy if needed
