The document summarizes key differences that are emerging between UK and EU chemical regulations, specifically UK REACH vs EU REACH and UK RoHS vs EU RoHS. It notes that while the UK systems initially mirrored the EU systems, divergence is occurring as the UK establishes its own independent framework. Differences highlighted include candidate substance lists, authorization processes, restricted substances, and obligations for companies. It also discusses areas of UK RoHS that are lagging updates from the EU, such as exemptions and product marking requirements, and that the UK will no longer be part of EU reviews and changes to RoHS.
