KKDIK Registration Deadline 2026: Türkiye Compliance Guide
KKDIK • TÜRKİYE • 2026
Companies manufacturing in or importing substances into Türkiye should verify substance identity, supply-chain role, tonnage, use and exemption status before the 30 September 2026 planning milestone. This guide provides a practical route to an auditable registration file.
KKDIK deadlines — the complete table
Legal basis: Amendment to the KKDIK Regulation, Official Gazette 23.12.2023 No. 32408 · Chemicals Advisory Group decisions (24.12.2025, 10.02.2026, 16–18.02.2026) · Ministry announcement, 10 March 2026. · Last updated: 23 August 2026.
| Obligation | Who is covered | Deadline |
|---|---|---|
| Lead registrant provisional registration | The company designated as lead in a joint submission | 31 March 2026 (passed) |
| Member company provisional registration | Member companies in a joint submission | 30 September 2026 |
| Individual provisional registration | Companies filing alone for substances with no identifiable lead registrant, stating the justification in KKS | 30 September 2026 |
| The Ministry expects every company manufacturing or importing 1 tonne per year or more — regardless of tonnage band — to hold at least a provisional registration number by 30 September 2026. A substance without one cannot be placed on the market after that date. | ||
| Tonnage / hazard criterion | Full registration deadline |
|---|---|
| 1,000 tonnes/year and above · CMR Category 1A or 1B at 1 tonne/year and above · Aquatic Acute 1 or Aquatic Chronic 1 (H400/H410) at 100 tonnes/year and above | 31 December 2026 |
| 100 tonnes/year and above (without the special hazard criteria above) | 31 December 2028 |
| 1 tonne/year and above (standard substances in the 1–100 tonne range) | 31 December 2030 |
| Tonnage is calculated per substance and per calendar year on a CAS basis. Using the same substance in several products adds up rather than splitting the tonnage. Joint data-sharing processes (MBDF) run until 31 December 2032. | |
The most common mistake: looking at a 2030 full-registration date and skipping the 2026 threshold. A substance in the 1–10 tonne band still needs a provisional registration number on 30 September 2026, otherwise placing on the market stops.

To meet the deadline, follow the sequence described in our guide to KKDIK registration.
Confirm the legal role and substance scope
A company may act as manufacturer, importer, downstream user or only representative across different supply flows. The assessment must therefore be performed by substance, product and supplier rather than at company level only.
Commercial product names are not sufficient identifiers. CAS/EC information, composition, impurities and the relationship between mixtures and their constituent substances should be checked against supporting documents.
- Legal entity and KKS account details
- Substance identity and composition evidence
- Annual tonnage calculation and source records
- Uses, suppliers and Türkiye importer mapping
Build an evidence-led submission package
Every material data point submitted to KKS should be traceable to an approved source. The file should show who supplied, reviewed and approved each item and how later changes will be controlled.
Procurement, customs, sales, production and product stewardship records should be reconciled. Differences are resolved before submission rather than hidden by a single summary spreadsheet.
Work with a Türkiye-based compliance team
ONAY Engineering has supported chemical regulatory projects since 2009. Our work combines regulatory scope assessment, substance and tonnage data control, KKS preparation and an auditable action plan.
The final obligation and route depend on the actual substance, use, supply chain and legal-entity data. A case-specific review is required before making a submission decision.
Frequently asked questions
Does a low tonnage automatically remove KKDIK obligations?
No. Tonnage is only one input. Substance scope, role, use and applicable exemptions must be reviewed together.
Can a product trade name be used as the substance identity?
No. Substance identifiers and composition evidence are needed, including the relevant constituents of mixtures.
