CLP Classification and Labelling
Classification, labelling and packaging of substances and mixtures for the European Union market.
CLP is Regulation (EC) No 1272/2008 on the classification, labelling and packaging of substances and mixtures. It is the European Union implementation of the United Nations Globally Harmonized System, and it governs how a hazard is determined, how it must be communicated on the label, and how the product must be packaged.
What CLP requires
CLP requires that substances and mixtures placed on the European Union market are classified according to defined hazard criteria, labelled with the elements that follow from that classification, and packaged appropriately. Classification drives everything downstream, so an error there propagates into the label, the safety data sheet and the transport documentation.
Label elements
A CLP label carries the product identifier, hazard pictograms, a signal word, hazard statements and precautionary statements, supplier details, and where required the nominal quantity. Language requirements apply in each member state where the product is sold. Certain products also require child resistant fastenings or tactile warnings.
Harmonised classification
Some substances carry a harmonised classification that is legally binding across the European Union and must be applied as given rather than self classified. Checking whether a component carries a harmonised entry is part of any correct classification exercise.
Notification duties
Classification and labelling information for substances is notified to the inventory maintained by the European Chemicals Agency. Separately, hazardous mixtures are subject to poison centre notification, which introduces a unique formula identifier that must appear on the label. These are distinct obligations from registration under REACH.
What we do
Classify substances and mixtures against the CLP criteria. Check components against harmonised classifications. Prepare compliant label content including hazard and precautionary statement selection. Advise on poison centre notification and the unique formula identifier. Align the label with the safety data sheet so the two do not contradict each other.
Frequently asked questions
What is CLP?
CLP is the European Union regulation governing how chemical hazards are classified, how they must be communicated on labels, and how hazardous products must be packaged. It is the European Union implementation of the Globally Harmonized System.
What is the difference between CLP and GHS?
GHS is a United Nations framework that jurisdictions adopt selectively. CLP is the legally binding European Union implementation of it. A product described as GHS compliant is not necessarily CLP compliant, because CLP makes specific choices that other jurisdictions do not.
Can I use my existing label in the European Union?
Only if it was built to CLP. Labels prepared for other jurisdictions commonly differ in the hazard statements selected, the pictograms applied and the language requirements, so they usually need reworking rather than translating.
What is a unique formula identifier?
It is an identifier connected to poison centre notification for hazardous mixtures, which must appear on the label of products within scope. It is a separate obligation from classification itself.
Need your product classified and labelled for the EU?
Send us the formulation and the markets in scope. We will classify it and prepare label content that matches the safety data sheet.
