A proposed amendment to the REACH Restrictions Roadmap was presented by the European Commission at CARACAL 55 on 30 June 2025. The draft includes the addition of N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) to Annex I (Pool 0, entry 6.2) and the removal of tetrahydrofuran (THF) from Annex II (entry 1.11). These proposed updates reflect shifting regulatory priorities under the EU’s Chemicals Strategy for Sustainability and have direct implications for manufacturers, importers, and downstream users.
What Is Being Proposed in the REACH Update?
Under the proposal, 6PPD—a chemical antioxidant used in rubber tyres—is slated for inclusion due to concerns over aquatic toxicity and reproductive risks. The Netherlands and Austria support the restriction, which could apply to rubber tyres and other rubber products. If agreed, the restriction dossier would be submitted to ECHA in Q1 2026.
Conversely, Germany has proposed to withdraw THF from consideration for restriction, citing minimal consumer exposure and limited use in DIY applications. This decision follows a re-evaluation of risk based on additional data.
Regulatory and Industry Implications
If formalised, the 6PPD restriction could have widespread implications for the automotive and rubber sectors, necessitating reformulation, product redesign, or substitution. It also sets a precedent for the treatment of tyre-related chemicals under REACH.
While the removal of THF lowers short-term regulatory pressure, industry should remain alert to future developments, especially regarding classification and labelling revisions.
Next Steps and Industry Response
The CARACAL 55 discussion marks the initial step in the decision-making process. Should the proposed amendment be adopted, a restriction dossier for 6PPD will be formally registered. Stakeholders should prepare for public consultation phases and begin assessing supply chain impacts.
For now, THF will no longer be actively considered for restriction, although safety monitoring continues under other regulatory pathways.
