What is IUCLID?
IUCLID (International Uniform Chemical Information Database) is the software used to record chemical substance information in a standard international format and to build technical registration dossiers. Under KKDIK (Turkey REACH) and REACH, a substance’s identity, physico-chemical properties, toxicological and ecotoxicological data, uses and exposure information are compiled in IUCLID. The dossier is then submitted through KKS (KKDIK) or REACH-IT (REACH). A correct and complete IUCLID dossier is critical for acceptance of the registration and for any subsequent evaluation or inspection. ONAY Mühendislik prepares and manages IUCLID technical dossiers.

IUCLID in one paragraph
IUCLID is the software used to assemble a chemical registration dossier. It stores substance identity, study summaries, classification and exposure scenarios in a standard structure that regulators can read directly. Turkey accepts dossiers in this format through the KKS system.
What goes into the file
- Identification and composition of the substance
- Physicochemical properties
- Toxicological and ecotoxicological studies
- Identified uses and exposure scenarios
- Classification and labelling
Practical tips
Record the reliability of every study you import, describe uses specifically rather than generically, and re-run the completeness check after any edit. These three habits prevent most of the requests for further information that delay dossiers.

Updating the dossier
A dossier is a snapshot rather than a conclusion. A change of supplier, a reformulation or a rise in volume all require an update, and new classifications feed into it as well. Schedule an annual review instead of reacting only when the authority asks a question.
Who uses it, and when
IUCLID is used by whoever compiles the dossier: the lead registrant for the joint part and each member for its own section. Work in it starts once substance identity is settled and data access is agreed, because importing study records before that usually means redoing them later.
