HSE Agency Opinion Retains GB CLP Classification for Silanamine (CAS 68909-20-6)

In September 2025 HSE issued an Agency Opinion confirming that the existing GB mandatory classification for silanamine (CAS 68909-20-6) remains STOT RE 2 (lung; inhalation) H373 with supplementary statement EUH066 under the UK CLP framework. This keeps GB aligned with the EU and Northern Ireland harmonised classification and, while not changing obligations, reinforces that suppliers of silanamine biocidal products must maintain labels and safety data sheets consistent with this chronic inhalation hazard profile.
