    What is the CLP Regulation, and how does it work?

    CLP (Classification, Labelling and Packaging) is Regulation EC 1272/2008, the EU's implementation of the UN Globally Harmonised System (GHS). It governs how substances and mixtures are classified for hazard, how they are labelled and how they are packaged. UK CLP runs in parallel post-Brexit.

    Quick answer

    The CLP Regulation (Regulation EC 1272/2008) is the EU law that implements the UN Globally Harmonised System (GHS) for chemicals. It governs how substances and mixtures are classified for physical, health and environmental hazards, what must appear on the label (pictograms, signal word, H and P statements), how they are packaged and, for mixtures, the UFI code and Poison Centre Notification (PCN). UK CLP runs in parallel post-Brexit.

    How this connects to Worldover

    Keeping SDS, REACH and CLP current across a growing substance master?

    Worldover holds the substance, mixture, SDS and label as one live record so REACH, CLP and multi-market SDS regenerate the moment the underlying data changes.

    How does hazard classification work under CLP?

    A substance or mixture is classified against the hazard classes in Annex I of CLP: physical (e.g. flammable, oxidising), health (e.g. acute toxicity, skin sensitisation, carcinogenicity) and environmental (e.g. aquatic toxicity). For mixtures, classification uses bridging principles, additivity formulas and cut-off values to derive the hazard from the components.

    What must appear on a CLP-compliant label?

    A CLP-compliant label carries the product identifier, supplier identity, nominal quantity, hazard pictograms (GHS01 to GHS09), signal word (Danger or Warning), hazard statements (H-codes), precautionary statements (P-codes) and any supplementary information. Tactile warnings and child-resistant fastenings are required for certain hazard classes.

    What is the UFI code and poison centre notification?

    Since 2021, mixtures classified for health or physical hazards placed on the EU market for consumer or professional use must carry a Unique Formula Identifier (UFI) on the label, and the formulation must be notified to the appointed poison centre in each Member State via the harmonised Poison Centre Notification (PCN) portal.

    Worldover for this

    CLP classification, labelling and SDS in lockstep.

    Worldover classifies mixtures, generates compliant labels and SDSs in every required language and keeps UFI codes, PCN submissions and poison-centre notifications synced.

    What are the recent and upcoming changes to CLP?

    The 20th and 21st Adaptations to Technical Progress (ATPs) introduced new hazard classes covering endocrine disruptors and persistent substances (PMT, vPvM) in 2023, with phased transition periods running through 2026 to 2028. Any platform you rely on for CLP must track these dates per substance and per mixture.

    Managing CLP in your operation

    CLP changes trigger relabelling requirements, SDS updates, and in some cases reformulation, across every product that contains the affected substance. The work compounds quickly when a single classification touches dozens of mixtures and markets.

    How Worldover covers it

    Worldover keeps every formulation tagged against the live CLP Annex VI. When a classification changes, affected SDS documents are flagged for update, Willow generates revised labels and hazard statements for review, and downstream notifications such as PCN are queued automatically.
