Stakeholder Consultation on PFHxS and PFHxS-related Substances

Stakeholder Consultation on PFHxS and PFHxS-related Substances

Socio-Economic Assessment of PFHxS and PFHxS-related Substances

Perfluorohexane sulfonic acid (PFHxS) and its salts have been identified as substances of very high concern due to their very Persistent and very Bioaccumulative (vPvB) properties according to Article 57 e) of REACH in July 2017.  PFHxS and related substances may be present in electrical equipment, fire-fighting foams, food contact papers, semiconductors, water/stain-proofing agents, cleaning and polishing products (as surfactants or surface protection agents) and metal plating.  These substances have also been used as raw materials to produce PFAS based products and are also unintentionally produced during industry processes; for example, PFHxS is a known impurity in the production of PFOS. Norway has submitted a proposal to add PFHxS and PFHxS related substances to the Stockholm Convention for Persistent Organic Pollutants.

Risk & Policy Analysts (RPA), together with Arche Consulting have been appointed by the Norwegian Environment Agency to collect information on the uses of PFHxS and PFHxS-related substances, alternatives, substitution costs and a socio-economic analysis for the proposed REACH restriction and for the upcoming Stockholm Convention process.

You can find a letter of confirmation, including background information on the study, and a list of PFHxS substances under Supporting Documentation on the lower right-hand side of this webpage.


The purpose of this consultation is to gather information from as many relevant stakeholders as possible, which will be used as input in the development of the restriction proposal.  This includes inputs on uses of PFHxS and PFHxS-related substances, the manufacture and import of PFHxS and PFHxS-related substances, emissions, alternatives and economic impacts.

Responses to the questionnaire for this stakeholder consultation will be handled in the strictest confidence, and the data provided by all respondents will be collated, aggregated and anonymised before being included in any reporting. Under Supporting Information you will find a confidentiality note describing in detail the handling of confidential data.
