Under the KKDİK Regulation (Turkish REACH), substance registrations must be completed according to specific deadlines based on tonnage and hazard classification. Substances manufactured or imported in quantities greater than or equal to 1,000 tonnes per year must be registered by 31 December 2026. This deadline also applies to substances ≥ 100 tonnes per year classified as Aquatic Acute 1 (H400) or Aquatic Chronic 1 (H410), as well as substances ≥ 1 tonne per year classified as CMR (Carcinogenic, Mutagenic, or Reproductive toxicants, Category 1A or 1B).
For substances manufactured or imported in quantities ≥ 100 tonnes per year, the registration deadline is 31 December 2028. Finally, for substances ≥ 1 tonne per year, the registration must be completed by 31 December 2030.
These deadlines ensure that all applicable substances are fully registered within the stipulated timeframes to remain compliant with KKDİK.
