I posted earlier with the European Commission Notices to Companies. The European Chemicals Agency (ECHA) has also issued advice to companies. This covers :
(1) general
(2) Reach
(3) CLP (Classification, Labelling & Packaging)
(4) BPD – Biocides (see also my earlier post on the European Commission Notice to Companies, and Q&A)
(5) PIC
The ECHA information is accessed here.
