15 Complex substances such as slags and drosses – inorganic UVCBs (iUVCBs) – which are generated as by-products from producing and transforming lead are also covered by the Consortium. Where they are produced and used under Strictly Controlled Conditions, manufacturers and importers may register isolated intermediates with reduced information requirements and lower ECHA fees and must submit detailed information on those means for rigorous containment and to minimise emissions.

Below is a list of iUVCBs managed by the Consortium, with links to composition information and the registration information disseminated on the ECHA website.

The Lead REACH Consortium is currently developing new-format Substance Identity Profiles for its iUVCBs, based on a template developed by Eurometaux in light of substance ID discussions with ECHA, in consultation with active registrants of each substance. Work to refine substance ID for iUVCBs and improve dossier quality also continues under MISA.

This page is updated as the new-format SIPs are agreed by registrants and have been submitted to the Lead Registrants for dossier updates.
