EU CLP Regulation Hazard Labelling, Digital Labelling Requirements, and Poison Centre Notification (PCN) Obligations
ENFORCEMENT TIMELINE
In force since January 20, 2009 (PCN/UFI requirements fully applicable from 2021, with digital labelling provisions phased in since)
Overview
This card focuses on the labelling and packaging requirements under Titles II and III of the EU CLP Regulation (Regulation (EC) No 1272/2008), together with the associated Poison Centre Notification (PCN) obligations.
CLP requires the packaging of classified hazardous substances and mixtures to carry the correct pictograms (the red-bordered GHS symbols), signal words ('Danger' or 'Warning'), hazard statements (H-phrases), and precautionary statements (P-phrases). For hazardous mixtures intended for consumer or professional use, companies must also print a 16-digit Unique Formula Identifier (UFI) on the label and submit composition and toxicological information online to Member States' poison centres (PCN). Recent amendments to CLP have also introduced relaxed digital labelling requirements, allowing certain space-constrained products to display some label content via QR code.
Enforcement Timeline
January 1, 2021: UFI and PCN obligations become mandatory for hazardous mixtures intended for consumer and professional use.
January 1, 2024: PCN obligations extend to hazardous mixtures intended solely for industrial use.
January 1, 2025: The transition period for existing products previously notified under Member States' individual national systems ends.
2026–2028: New minimum font-size requirements under the amended CLP Regulation take effect, along with formal rollout of digital labelling for certain chemical products.
Business Impact
Companies exporting or selling hazardous chemical mixtures — such as paints, adhesives, and detergents — into the EU must produce GHS-compliant labels in each Member State's official language, while ensuring packaging meets mechanical requirements such as visibility, child-resistant fastenings, and tactile warnings. They must also submit complete product composition, physical properties, use classification, and UFI codes to ECHA's PCN portal in advance; without this, customs clearance and sale within the EU are not possible.
The new digital labelling framework allows some multilingual text and detailed precautionary information to be disclosed online via QR code, but mandatory physical label elements — pictograms, signal words, emergency contact information, and the UFI code — must still be printed directly on the packaging under strict requirements.
