Active Implantable Medical Devices Directive-repealed

Active Implantable Medical Devices Directive - Hazardous Substances

This list contains hazardous substances for purposes of Directive 90/385/EEC on active implantable medical devices, particularly as regards Article 3 and Annex I (Essential Requirements). This non-exhaustive database is derived from: Table 3 of Annex VI to CLP, REACH Candidate List of SVHCs, and Directive 2000/54/EC's Annex III (Biological Agents list). Please note that Regulation (EU) 2017/745 on medical devices has repealed Directive 90/385/EEC and begun to apply from 26 May 2021. Nevertheless, Article 120 of the Regulation provides for a transitional period allowing medical devices, under specified conditions (e.g., placed on the market prior to 26 May 2021), to continue to comply with the Directive. In accordance with the fourth paragraph of Article 120, this period ends 26 May 2025.

EU Ecolabel Regulation

Ecolabel - Restrictions for Hazardous Substances/Mixtures

This list contains a non-exhaustive inventory of substances based on the list of hazardous substances with harmonised classification and labelling (i.e. Table 3 of Annex VI to the CLP Regulation), and the Candidate List of substances of very high concern (SVHCs). Pursuant to Article 6(6) of the EU Ecolabel Regulation, the ecolabel must not be awarded to goods containing substances or mixtures classified according to the CLP as toxic; hazardous to the environment; and carcinogenic, mutagenic, or toxic for reproduction (CMRs). Nor are products allowed the ecolabel award when they contain SVHCs (per Article 57 of REACH). While the CLP's harmonised list contains many such substances, other ones not listed in Table 3 may also meet the criteria specified for classification under the CLP.
