This document discusses the regulatory challenges of standardizing safety data sheets (SDS) across different legal areas. It identifies differences in national chemical inventories, restricted substances lists, and SDS template requirements. Specific SDS sections like headings, languages, contents, and annexes vary between places like the EU and US. The document proposes using the EuPhraC structure within SDSComXML, but expanding it to accommodate regulations from other jurisdictions. It suggests standardizing some sections by legal area, like substance names or chemical safety assessments.
