Changes to the inquiry process

ECHA has reorganised the processing of inquiries. Inquirers for most already registered or successfully inquired substances will now be quickly directed to the relevant “Co-Registrants” page in REACH-IT, based on the numerical identifiers they provide.

For substances with ambiguous identifiers or where registrants or potential registrants do not exist, ECHA verifies the substance identity information. Nevertheless, previous and potential registrants are still responsible for discussing substance sameness and deciding whether their substances can be registered together.

More information can be found in the dedicated page on inquiry.
