EU/ECHA Starts CLH Consultation On Harmonised Classification Of Simple Cobalt Compounds

ECHA has opened an EU CLP public consultation from 11 May 2026 on a harmonised classification proposal for cobalt dihydroxide, cobalt(2+) propionate and cobalt(II) 4-oxopent-2-en-2-olate as part of a wider group of simple cobalt compounds. If adopted, the classification would place these cobalt compounds under stringent CMR and aquatic hazard labelling, driving tighter REACH risk management, possible restrictions and strengthened workplace controls across coatings, polymers, batteries and other cobalt-using applications.

Industry Response to RAC Opinion on Harmonised Classification of 1,3‑Diphenylguanidine (CAS 102‑06‑7)

An industry association led by Draslovka has submitted a detailed position paper to EU CARACAL challenging ECHA’s RAC opinion that 1,3-diphenylguanidine should be classified as a Category 1B reproductive toxicant and skin sensitiser, arguing instead for a less severe Repr. 2 classification and no sensitisation hazard. If regulators accept some or all of these arguments, the final CLP harmonised classification for this accelerator could be softened, easing future labelling, risk-management and substitution pressures for manufacturers and downstream users while signalling how much weight regulators give to industry weight-of-evidence challenges.

European Sealing Association Position on Proposed EU PFAS Restriction

European Sealing Association has issued a February 2026 position paper on the proposed EU REACH restriction of PFAS, arguing that fluoropolymers and fluoroelastomers used in sealing devices are essential, polymers of low concern and should be exempted from any blanket PFAS ban. This signals strong industry pushback and highlights potential supply, safety and process risks if the final restriction does not carve out critical fluoropolymer uses, informing companies’ advocacy, substitution planning and PFAS risk assessments.
