Classification and labelling (CLP/GHS)

Globally Harmonized System of Classification and Labelling of Chemicals

Globally Harmonized System of Classification and Labelling of Chemicals


On December 16, 2008, the UN system GHS "Globally Harmonized System of Classification and Labelling" also came into force in Europe within the framework of the CLP Regulation of the EU. As a system for "classification and labeling of substances", GHS/CLP explicitly provides for expert judgements for many assessments, especially of a complex nature (toxicology, ecotoxicology).

The transition of classification and labeling to GHS/CLP is another part of the European chemicals policy. The regulation replaced the system of classification and labeling under the Substances Directive and the Preparations Directive. According to this, substances and mixtures (before CLP "preparations") had to be reclassified and the labels changed within certain deadlines.

Each hazardous mixture must be correctly classified, packaged and labeled before being placed on the market and must comply with the other chemical legislation (UFI, safety data sheet, emergency numbers...). Inspections by the authorities repeatedly show that many products do not comply with the regulations. Especially with imported goods and in online trade, the non-compliance rate is alarmingly high.


  • Notifications to the Classification and Labelling Inventory
  • Notification to the poison center notification (PCN)
  • Classification of substances and mixtures
  • Determination of the composition of mixtures (literature and database research, communication with suppliers and manufacturers, chemical analyses)
  • Collection of substance data required for classification [literature and database research]
  • Obtaining the substance data required for classification [tests (phys-chem., tox., ecotox.); QSAR calculation] incl. development of an efficient test strategy
  • Preparation of safety data sheets in all EU languages
  • If necessary, handling of communication between companies via a neutral third party for reasons of confidentiality
    Mediation in case of different self-classifications of the same substance/mixture by several companies
  • Support in related legal areas such as 
    - Transport of dangerous goods (ADR/RID) 
    - Classification in water hazard classes (WGK)
    - Major Accidents Ordinance
    - Biocidal Products Ordinance
  • Consulting for online trade
  • REACH service
  • Training courses

The aim of the CLP Regulation is not only standardisation, but also harmonisation with regard to the previously separate regulatory areas of transport and dangerous goods law, handling law, occupational health and safety, environmental protection and consumer protection. The implementation of CLP therefore requires a systems approach.


  • Save the time of familiarizing yourself with the extensive and complex set of rules
  • Minimize risks, because we help you complete required tasks on time and avoid unnecessary activities
  • Increase security, because our experience in handling sensitive data enables you to protect your trade secrets despite the obligation to disclose data contained in CLP
  • Avoid downtime and ensure the undisturbed continuation of your business activities
  • Recognize internal savings potentials in occupational health and safety
  • Expand the circle of suppliers you know and get to know new customers
  • Rely on a competent partner, because we constantly monitor the practice of implementing CLP in the EU
  • TÜV SÜD is a globally recognized partner in questions of chemicals law. In the related field of REACH, we are a leading expert and act internationally as sole representative

TÜV SÜD's experts will support you every step of the way in implementing CLP and recommend: Do not look at CLP in isolation, but in conjunction with REACH!
