In short: there are three ways to prepare a GBF (Turkish SDS) under KKDİK (Turkish REACH): employ a KDU (Chemical Assessment Expert) on staff, buy the service from an external KDU or consultancy, or speed the work up with software that a KDU uses. They are not mutually exclusive; which one fits depends on your number of products, how often you revise and your in-house expert capacity. The legal requirement is the same for all of them: the GBF is prepared by a KDU.

The rule that does not change

Since 1 January 2024, a GBF in Türkiye can only be prepared by a Chemical Assessment Expert (KDU) (KKDİK Article 27/1). This holds whichever route you choose. Software does not replace the KDU; consultancy is the KDU supplied from outside. Details: what is a KDU?

The three routes compared

RouteStrengthPoint to watch
KDU on staffAn expert who knows the product and the production and is reachable at every revision; continuous know-how.Fixed cost; capacity may be more than a company with few products needs.
External KDU / consultancyService as needed; expertise comes ready-made.Total cost and waiting time grow as the number of products and revisions grows; the flow of information depends on the company.
KDU + softwareRepetitive work (data collection, classification calculation, document generation) is automated; the expert focuses on the final check.You need to question the software's data source, reasoning and editability; the responsibility is still the KDU's.

We give no figures in the table: cost varies from company to company depending on the number of products, revision frequency and how the expert works.

Which makes sense when?

  • Few products, rare revisions: an external KDU is usually enough; if you want the GBF prepared with software, your KDU can use the tool.
  • Many products or frequent recipe changes: a tool that automates the repetitive work saves time for both the KDU and the company.
  • Export: if you need the language and format of the target country (for example REACH Annex II in the EU), a tool with multilingual output reduces the workload. See SDS for export to the EU.
  • Consultancy firms: when managing the products of several clients, saved forms in a single panel and quick revision make the difference.

Where does Chemoris stand?

Chemoris is not a consultancy service; it is a tool used by KDUs and companies. It pulls ECHA CHEM data, classifies the mixture with CLP rules and shows the reasoning, and delivers the 16-section GBF as an editable Word document. All fields are editable; the final check and the responsibility stay with the user. New accounts get 1 free GBF credit, no credit card needed. For the options see the pricing page; to see the method, read how to prepare a Turkish SDS.

Frequently asked questions

Does using software reduce the KDU's responsibility?

No. The supplier and the KDU who prepares the form are responsible for its content; the software is a tool. The classification and the text must be checked by the expert.

If I have no KDU, can I prepare a GBF with software alone?

No; since 2024 the GBF must be prepared by a KDU. A company without a KDU must work with an external KDU; the KDU can use a tool such as Chemoris if they wish.

Can consultancy firms use software too?

Yes. Consultants can keep and revise the forms of several clients in a single panel; the responsibility still lies with the KDU providing the service.
