REACH & CLP
To meet the requirements of Regulation (EC) No 1907/2006 (REACH) on the registration, evaluation, authorisation and restriction of chemicals, companies must identify and manage the risks associated with the substances they manufacture or place on the EU market.
In addition, Regulation (EU) 2020/878 sets out the rules for preparing Safety Data Sheets (SDS), which provide essential information on chemical substances and mixtures used within the European Union.

Classification, labelling and packaging of substances (CLP)
Regulation (EC) No 1272/2008 (CLP) requires manufacturers, importers and downstream users to classify, label and package hazardous chemical substances before placing them on the market.
Annex VIII to the CLP Regulation sets out harmonised requirements for Poison Centres Notifications (PCN). The information submitted in these notifications is used by toxicology centres in emergency situations to ensure an appropriate medical response in incidents involving chemical mixtures.
How CHEMLEX can support you
At CHEMLEX, we provide comprehensive support to ensure full compliance with REACH and CLP, including:
REACH
The REACH and CLP Regulations form the foundation of the European chemicals management system. Proper classification, labelling, preparation of Safety Data Sheets and registration of substances are essential to ensure user safety and full regulatory compliance.
CHEMLEX provides comprehensive support in meeting all obligations under both regulations, assisting companies in the correct preparation of documentation and labelling for chemical products.
We carry out product audits to assess components in terms of registration requirements or potential exemptions under REACH.
We update documentation for substances or mixtures that have already been registered.
We support companies in joining an existing REACH registration through a Letter of Access (LoA), enabling registration of the same substance without the need to develop a full dossier independently.
We prepare Safety Data Sheets (SDS) compliant with REACH requirements, assist in generating the UFI (Unique Formula Identifier) when required, and submit information on hazardous mixtures to Poison Centres (PCN) via the ECHA portal.
REACH – our services
Registration of substances and mixtures
We provide end‑to‑end support throughout the registration process, including:
REACH‑compliant product audit
We analyse product components to determine:
Documentation updates
We update dossiers for substances and mixtures that have already been registered, ensuring alignment with the latest ECHA requirements.
Safety Data Sheets, UFI and PCN submissions
We prepare Safety Data Sheets (SDS) compliant with REACH requirements, assist in generating the UFI (Unique Formula Identifier), and submit information on hazardous mixtures to Poison Centres (PCN) via the ECHA portal.
CLP — the essential basis for correct SDS preparation
REACH and CLP — the essential basis for correct SDS preparation
While the Safety Data Sheet (SDS) is prepared in accordance with the REACH Regulation, the key framework for its correct development is CLP — the regulation that defines the criteria for classifying chemical substances and mixtures in terms of hazards to human health and the environment.
CHEMLEX supports companies in meeting all obligations under CLP, ensuring accurate classification, proper labelling and the preparation of EU‑compliant product labels.

Important information for exporters
Companies placing chemical products on the markets of other EU Member States are required to provide Safety Data Sheets (SDS) and labels in the official language of the destination country.
CHEMLEX offers full support in adapting documentation to the linguistic and legal requirements of each market.

Additional steps where we provide effective support
We offer assistance in generating the UFI (Unique Formula Identifier) whenever it is required.
We support the submission of information on chemical mixtures to Poison Centres (PCN) when such notification is mandatory.
We perform updates and assessments of existing Safety Data Sheets (SDS) to verify their compliance with current regulations and provide recommendations for required changes.
We prepare label content tailored to the specific characteristics of products within our areas of expertise, or we review and assess the correctness of existing label content.
Important
A change in the CLP classification of a chemical substance typically requires corresponding updates to the product label or accompanying documentation (if no label is used). Companies are obliged to ensure correct and compliant labelling before placing a product on the market.
UFI generation
We assist in generating the UFI (Unique Formula Identifier) whenever it is required for a chemical mixture.
PCN submissions (Poison Centres Notification)
We submit information on hazardous mixtures to Poison Centres (PCN) via the ECHA portal whenever notification is mandatory.
SDS review and updates
We verify the compliance of existing Safety Data Sheets (SDS) with current regulations, identify required changes and update documentation in line with the latest CLP and REACH requirements.
Label content development and verification
We prepare CLP‑compliant label content, review the correctness of existing labels and ensure that all information reflects the specific characteristics of products within the CHEMLEX scope of activity.
Classification change = label change
A change in the CLP classification of a chemical substance typically requires an update to the product label or accompanying documentation.
Businesses are obliged to ensure that the product is correctly labelled before it is placed on the market.
CHEMLEX ensures that your products remain compliant with the latest regulatory requirements and reach the market safely and responsibly.
