KKDIK Regulation Imprint, Sections and Annexes

KKDIK Regulation, fully known as the Regulation on Registration, Evaluation, Authorization and Restriction of Chemicals, is the basic legislation regulating the placing of chemicals on the market in Turkey. It was published in the Official Gazette dated 23 June 2017 and numbered 30105. It is Türkiye's adaptation of the REACH Regulation in the European Union and is based on the same principle: no data, no market.

KKDIK Regulation imprint

  • Full name: Regulation on Registration, Evaluation, Authorization and Restriction of Chemicals
  • Publication: 23 June 2017, Official Gazette number 30105 (duplicate)
  • Competent institution: Ministry of Environment, Urbanization and Climate Change
  • System: Chemical Registration System (KKS)
  • EU equivalent: REACH Regulation (1907/2006)

What parts does the Regulation consist of?

KKDIK Regulation consists of twelve parts. Knowing which obligation is regulated where makes it easier to navigate to the right article when preparing a file.

  1. General Topics — purpose, scope, basis and definitions
  2. Registration of Substances — registration obligation, tonnage thresholds, dossier content
  3. Sharing Data and Avoiding Unnecessary Testing — MBDF, joint registration, access letter
  4. Information Within the Supply Chain — safety data sheet and information flow
  5. Downstream Users — terms of use and verification obligation
  6. Evaluation — file and item evaluation
  7. Permit — substances subject to authorization and application
  8. Restriction of Certain Harmful Substances, Mixtures and Articles
  9. Fees — registration and application fees
  10. Information — access to information and privacy
  11. Audit and Sanction
  12. Miscellaneous and Final Provisions — transitional provisions and schedule

Who is bound by the KKDIK Regulation?

Obligation varies depending on the company's role. The manufacturer producing in Turkey records that he produces, and the importer records that he imports. Manufacturers outside Türkiye cannot register directly; It appoints a sole representative resident in Turkey. The downstream user does not register but must verify that his use is covered in the supplier's file.

Registration threshold and tonnage

The registration obligation starts with a threshold of 1 tonne per year per legal entity. The amount is calculated based on the calendar year total; Quantities from different suppliers are added together and counted in proportion to the share of the substance in the mixture. As Tonnage band increases, the requested data set expands, and above a certain threshold, chemical safety report becomes mandatory.

Inspection and enforcement

The eleventh part of the Regulation regulates inspection and enforcement. Unregistered production or import may result in administrative fines as well as suspension of supply of the substance to the market. The first document requested in an audit is usually the item inventory, tonnage records and registration evidence.

Annexes of KKDIK Regulation: From Annex-1 to Annex-18

The KKDİK Regulation contains eighteen annexes. Its articles establish the framework, while the annexes set out the practical requirements: the data required in registration dossiers, exempt substances and restricted uses. The annexes largely correspond to those of EU REACH. Annex 18 is specific to Türkiye and has no equivalent in EU REACH.

KKDIK Regulation annexes and their equivalents in practice
AppendixTitleWhat does it do in practice?
Annex-1General provisions for the evaluation of substances and preparation of chemical safety reportsProvides the skeleton of the chemical safety report. Every record over 10 tons/year is processed according to this annex.
Annex-2Requirements for the preparation of safety data sheetsHere is the 16-chapter structure of the GBF; The primary basis of the SDS preparer.
Annex-3Criteria for substances registered between 1–10 tonnesDetermines which item will require the full data set in low tonnage.
Annex-4Substances exempt from registration obligationThe first stop of the exemption check; Substances such as water, nitrogen and glucose are here.
Annex-5Exemptions from registration obligationExemptions based on situation and not on substance basis: unprocessed substances found in nature, by-products.
Annex-6Information requirements referred to in clause 11The core of each registration file: registrant ID, substance identification, manufacturing and use information.
Annex-7Standard information requirements for substances of 1 tonne and aboveData set of the lowest tonnage band: physico-chemical properties and main toxicity/ecotoxicity.
Annex-8Standard information requirements for substances of 10 tonnes and aboveis added above Annex-7; In this band, a chemical safety report is also mandatory.
Annex-9Standard information requirements for substances of 100 tonnes and aboveLong-term toxicity and environmental fate studies come into play and a test recommendation is made.
Annex-10Standard information requirements for substances of 1,000 tonnes and aboveThe most comprehensive data set; The band with the highest cost and time.
Annex-11General rules for adapting standard test regimesWay to present data without testing: read-across, QSAR, weight of evidence, reasons for skipping tests.
Annex-12Substance evaluation and chemical safety report preparation by downstream usersIf your use is not in the supplier's exposure scenario, the downstream user report is prepared according to this annex.
Annex-13Criteria for the determination of PBT and vPvB substancesThresholds for the assessment of persistent, bioaccumulative, toxic; Technical gate of the SVHC route.
Annex-14List of substances subject to authorizationThe substance on the list cannot be placed on the market without permission. Corresponding to EU REACH Annex XIV.
Annex-15FilesContent of the files to be submitted to the Ministry during the restriction and permit processes.
Annex-16Socio-economic analysisFramework of the social benefit argument of use in the permit application.
Annex-17Restrictions on the manufacture, placing on the market and use of certain harmful substances, mixtures and articlesThe most frequently asked attachment. Restriction list: certain uses are prohibited or conditional if the substance is here. It is the equivalent of EU REACH Annex XVII and is regularly updated.
Annex-18Conditions for obtaining Chemical Evaluation Specialist qualification certificateTurkey-specific annex. Determines who can approve the registration file: A person without an KDU certificate cannot sign the file. There is no such obligation in EU REACH.

Which supplement comes into play at which tonnage?

The only thing that determines the size of the log file is the tonnage band. Bands are cumulative: the upper band includes the data of the band below it.

Mandatory additions according to tonnage band
Annual amount (per legal entity)Mandatory data attachmentChemical safety report
1 – 10 tonsAnnex-6 + Annex-7Not required
10 – 100 tonsAnnex-6 + Annex-7 + Annex-8Required
100 – 1,000 tonsAnnex-6 + Annex-7 + Annex-8 + Annex-9Required
1,000 tons and aboveAnnex-6 + Annex-7 + Annex-8 + Annex-9 + Annex-10Required

The threshold is1 tonne per year per legal person. If two different companies import the same substance in 0.6 tons each, there is no registration obligation; arises if a single company imports 1.1 tons. When the tonnage calculation is made incorrectly, there is a risk of unnecessary costs or incomplete records — you can check your situation with our liability test and see the cost from the 2026 duty tariff.

Evaluation, permission and restriction: three other columns

KKDIK is not just about registration. Here are our detailed guides for the other three pillars in the code's name:

KKDIK does not stand alone; SEA works in conjunction with the safety data sheet and UFI/PCN. See how the four connect and what obligations arise based on your role on one page: Türkiye chemical regulations map.

If you have a Exemption claim, first verify the scope: KKDIK excluded substances — which exemption removes what in waste, transit, intermediates, polymers and cosmetics.
