SVHC stands for “Substances of Very High Concern.” In the context of chemical regulations, SVHC refers to substances that have been identified as having particularly hazardous properties, such as being carcinogenic, mutagenic, toxic to reproduction (CMR), persistent, bioaccumulative, and toxic (PBT), or very persistent and very bioaccumulative (vPvB). These substances are subject to strict regulations and scrutiny due to their potential adverse effects on human health and the environment.

The term “SVHC” is commonly associated with the European Union’s REACH Regulation (Registration, Evaluation, Authorization, and Restriction of Chemicals). Under REACH, the European Chemicals Agency (ECHA) maintains a list of SVHCs. This list is regularly updated based on new scientific evidence and assessments.

Key points regarding SVHCs and the REACH Regulation include:

  1. Candidate List: The ECHA maintains a Candidate List of SVHCs. Substances may be included in this list based on various criteria, such as their intrinsic properties or their inclusion in international lists of hazardous substances.
  2. Authorization Process: Certain SVHCs may be subject to an authorization process under REACH. Companies wishing to use or place on the market substances listed as SVHCs may need to apply for authorization, especially if there are no suitable alternative substances or technologies.
  3. Communication in the Supply Chain: Manufacturers and importers of articles (products) containing SVHCs in concentrations above specified thresholds are required to communicate information about these substances along the supply chain. This aims to ensure that downstream users and consumers are informed about the presence of hazardous substances in products.
  4. Restricted Substances: Some SVHCs may be subject to restrictions on their use under REACH. Restrictions are implemented to manage the risks associated with certain substances and protect human health and the environment.
  5. Global Impact: While SVHCs and the REACH Regulation are specific to the European Union, the identification and regulation of substances of concern also occur in other regions. International organizations, such as the United Nations and the Organization for Economic Co-operation and Development (OECD), contribute to global efforts to address hazardous substances.
  6. Alternative Assessment: One of the key principles of REACH is to encourage the substitution of SVHCs with safer alternatives. This promotes the development and use of less hazardous substances in various industries.

The identification and regulation of SVHCs are part of broader efforts to enhance the safety of chemicals, protect human health, and minimize environmental impacts. Companies operating in the European market need to comply with REACH requirements regarding SVHCs to ensure the safe use of chemicals and products.
