SVHC (Substances of Very High Concern) refers to substances of high concern that have been evaluated by the European Chemicals Agency (ECHA) in accordance with the EU REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) regulations.

SVHC mainly has the following characteristics:

Serious impact on human health or the environment: SVHC is considered to have carcinogenic, teratogenic, hormonal interference and other harmful effects, or has a high risk of accumulation and toxicity to organisms in the environment.

Long term accumulation and difficult degradation: SVHC has persistence in the environment and is difficult to naturally decompose or disappear.

Widely used: SVHC may exist in various products, including electronic and electrical equipment, plastic products, cosmetics, textiles, etc.

According to REACH regulations, if a substance is identified as SVHC and its content exceeds 0.1% by weight, manufacturers and importers are required to provide notification to ECHA and appropriate safety information.

The EU's SVHC list is dynamic, with new candidate substances constantly being proposed, and some substances may also be included in the official candidate list. This list provides clear identification and management of SVHC by the public and businesses.

To ensure proper management of SVHC, companies need to conduct in-depth supply chain investigations to understand the SVHC substances that may be present in their products, and take necessary measures to reduce their risks or replace them with more sustainable and safe alternatives.

In summary, SVHC refers to chemical substances recognized by the European Union as having extremely high levels of concern, with potential hazards that require special attention and management. Enterprises should actively understand whether their products contain SVHC substances and take appropriate measures to reduce their potential risks in accordance with relevant regulatory requirements.
