Per- and Polyfluoroalkyl Substances (PFAS)

About PFAS

Per- and polyfluoroalkyl substances (PFAS), previously known as PFCs (per- and poly-fluorinated chemicals), and their derivatives, are a group of synthetic chemicals with many specialty applications. They can provide resistance to heat, to other chemicals or to abrasion and can act as dispersion, wetting or surface-treatment agents. There are many different types of PFAS, including:

• Perfluorooctane sulfonic acid, known as PFOS
• Perfluorooctanoic acid, known as PFOA
• Perfluorohexane sulfonic acid, known as PFHxS

In Australia, PFAS have been used in the past in a variety of industrial processes and in commercial and consumer products. PFOS, PFOA and related compounds were imported mainly for use as:

• Mist suppressants in the metal plating industry
• Hydraulic fluid in the aviation industry
• Surfactants in the photography industry
• Fire-fighting foams

Some imported articles such as textiles may have been treated with PFAS.

Our regulation of PFAS

We regulate the manufacture and importation of PFAS (including those that may break down to form perfluorinated substances such as PFOS and PFOA).

Importers and manufacturers (introducers) of these chemicals must comply with legal obligations under the Industrial Chemicals Act 2019. This includes registering their business with us and categorising their chemical importation or manufacture (introduction) before they can lawfully introduce these chemicals into Australia.

We also enforce import and export controls on PFOS, PFOA and related chemicals listed under the Rotterdam Convention. These controls prohibit the introduction or export of these chemicals unless an importer or exporter obtains our approval. The regulation of the use, release and disposal of PFAS in Australia is primarily a state and territory responsibility.

We contribute to other international activities to restrict the use of PFAS through the OECD Chemicals Committee and through our role in meeting the Australian Government's obligations under the Stockholm Convention.

Our work on PFAS

Between 2002 and 2008 we published alerts on the identified risks of PFAS, including recommendations to manage these risks. These alerts were published under the previous scheme, the National Industrial Chemicals Notification and Assessment Scheme (NICNAS) and you can read these alerts through the Australian Government Web Archive.

Between 2013 and 2019 we assessed the risks of a number of PFAS chemicals as part of a program of work to prioritise and accelerate the assessment of chemicals listed on our inventory. These assessments focused on PFOS and PFOA and their direct and indirect precursors (other chemicals that break down in the environment to form PFOS and PFOA). 

We also assessed the risks of related chemicals including shorter chain PFAS that may be used as replacements for PFOS and PFOA. These assessments include exposure and hazard information and risk management recommendations for industry. You can find these assessments by searching for the chemical’s name or CAS number on our website. The following table provides links to these assessments.
