What is SVHC?

SVHC = Substances of Very High Concern

A Substance of Very High Concern (SVHC) is defined by the European Chemicals Agency (ECHA) as a “substance that may have serious and often irreversible effects on human health and the environment”. The substances on the candidate list are not banned, but if a product contains SVHCs in concentration over 0.1% weight, the manufacturer or importer must disclose the substances presence to the ECHA.

The candidate list of SVHCs is published in accordance with Article 59(10) of the REACH Regulation. Members of the ECHA can propose adding any substances that fulfil one or more criteria defined by REACH.

What substances are on the candidate list?

The SVHC candidate list is updated whenever a proposal is made to add a new substance to the list. The ECHA initiates a 45 day public consultation period to determine if the substance should be included. If there are no adverse comments, the substance is included. Otherwise, the decision is made by the European Commission.

Important groups of SVHCs on the candidate list include:

  • Carcinogenic, mutagenic or toxic to reproduction (CMRs)
  • Persistent, bio-accumulative and toxic (PBTs)
  • Very persistent and bio-accumulative (vPvBs)
  • Seriously and/or irreversibly damaging the environment or human health (e.g. substances damaging the hormone system)

The full list of SVHCs can be found on the ECHA website.

How to comply with SVHC requirements?


REACH = Registration, Evaluation, Authorization and Restriction of Chemicals

REACH is a regulation that aims to protect human health and the environment from hazardous chemicals. It is enacted by the European Union and applied to industrial and consumer chemicals and formulations. Hohenstein helps brands, retailers and suppliers comply with the law.

SVHC Requirements

SVHC Requirements and Disclosure

  • Determine whether products contain any SVHCs in excess of 0.1% product weight. This is done with a chemical test of the products
  • Disclose the presence of SVHCs in products within 45 days upon request from consumers or customers
  • Ensure environmental compliance and product safety. Adding product use instructions can help customers and consumers stay safe
