The REACH registered substance data and the C&L Inventory portal will be upgraded from the 9th November.

Please be aware there may be intermittent unavailability while work in ongoing. The per substance REACH registration status will be made available as soon as possible thereafter. Likewise the per substance indication of harmonised C&L, Seveso directive, or notified C&L regulatory context will be made available as soon as possible.

Please note that it may take a week or two to have everything fully in place, and please be aware in the meantime that the Registration status may be incorrect and the CLP regulatory context may be incompletely shown.
