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.
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.
