KKDIK Temporary Registration and Full Registration Difference
KKDIK • Türkiye • 2026
Temporary registration and full registration are not the same thing. While temporary registration focuses on moving the company and the substance into the system with certain information, full registration; It requires more comprehensive preparation, such as data sharing, a common registry structure, technical dossier and, where necessary, chemical safety assessment.
Purpose and scope of the two stages
The most critical issue during the temporary registration phase is the correct match of the company role and the item ID. Incorrect CAS/EC information, composition range or representation relationship can directly affect the subsequent registration strategy.
At the full registration stage, technical data requirements, tonnage band, right of use of existing works, role in joint registration and keeping the file up to date come to the fore. The decision to act as a leader, jointly or individually, should not be based solely on cost.
- Provisional registration: correct identification, role, tonnage and essential declarations
- Full registration: technical dossier, data access and common registration strategy
- Both phases: demonstrable internal data and change management
How to set up a cost and schedule plan?
Cost items; It varies depending on the number of items, data gap, analysis need, data access fee, common record structure and consultancy workload. It is not healthy to assume that a single fixed price applies to all items.
Calendar; It should be divided into separate work packages as inventory verification, communication, data evaluation, contract, technical file and system submission. A delayed data access decision can affect the schedule of the entire file.
Correct migration plan
Temporary registration data should be retained as the initial data set for full registration, but must be revalidated. When supplier, tonnage, usage or composition changes, the impact of the dossier should be recorded.
ONAY Mühendislik creates a roadmap with current status, data gap, recording role, and target date for each item. Thus, management sees which decision will be taken, when and with what evidence.
