On 20 August 2025, the European Chemicals Agency (ECHA) announced that an updated Background Document for the proposed restriction of per- and polyfluoroalkyl substances (PFAS) under the REACH Regulation has been published. The update follows extensive stakeholder input on the original 2023 proposal and provides additional details on the scope and possible derogations.

Expanded Scope of the Restriction

The revised document incorporates feedback from over 5,600 consultation comments and now covers additional uses beyond the initial proposal. Newly addressed sectors include:

• Printing applications
• Sealing materials
• Machinery and equipment
• Technical textiles
• Explosives
• Military uses
• Certain medical applications, such as immediate packaging and pharmaceutical excipients
• Industrial uses including solvents and catalysts

Options for Continued Use under Conditions

The updated proposal introduces possibilities for time-limited or use-specific derogations in critical sectors where alternatives are not yet technically feasible. These could apply, for example, to semiconductors, energy technologies, or certain medical uses, provided strict conditions for controlling emissions are met.

Next Steps

ECHA’s Risk Assessment Committee (RAC) and Socio-Economic Analysis Committee (SEAC) will review the updated document and issue their opinions before the European Commission and EU Member States decide on the final restriction.

The updated Background Document can be found here.

On 8 August 2025, the European Commission adopted a regulation amending Annex XVII to REACH (Regulation (EC) No 1907/2006) concerning carcinogens, germ cell mutagens and reproductive toxicants (CMRs). This update reflects recent changes to the EU’s harmonised classification and labelling of chemicals.

New Substances Added to Annex XVII

The amendment incorporates substances newly classified as CMR category 1B under Commission Delegated Regulation (EU) 2024/1973. These substances are now listed in Appendices 2, 4, and 6 of Annex XVII, meaning that they cannot be supplied to the general public above the set concentration limits.

Among the substances included are:

• Diuron (CAS 330-54-1)
• Tetrabromobisphenol-A (CAS 79-94-7)
• N,N-dimethyl-p-toluidine (CAS 99-97-8)
• 4-nitrosomorpholine (CAS 59-89-2)
• 4-methylimidazole (CAS 822-36-6)
• Several phosphonium salts and diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide
• Dibutyltin compounds, including dibutyltin maleate and dibutyltin oxide

Derogation for Cumene in Aviation Fuels

The Commission also clarified the status of cumene (CAS 98-82-8). Although cumene had already been included in Annex XVII in 2023, the restriction had created practical issues for aviation fuels used by non-professional pilots. The new regulation introduces a derogation permitting the use of cumene in kerosene and gasoline for aviation that meet recognised international standards (e.g. Jet-A, Jet-A1, JP-x, DEF STAN, ASTM, EN 228).

Entry into Force and Application

The Regulation will enter into force 20 days after publication in the Official Journal of the EU. The restrictions related to the newly classified CMRs will apply from 1 September 2025, in line with the implementation of the updated CLP classifications.
