A regulatory term referring to a substance classified as hazardous pursuant to Article 3 of Regulation (EC) No 1272/2008.
Hazardous substance is not a battery-specific chemistry list in this Regulation; it is a cross-reference to the EU's broader CLP hazardous-classification regime. The important implication is that battery compliance here depends partly on another legal system's classification logic rather than on a bespoke battery-only definition.
Regulation (EU) 2023/1542 concerning batteries and waste batteries
a substance classified as hazardous pursuant to Article 3 of Regulation (EC) No 1272/2008;
Reference: Article 3, point 52
This term matters when teams map battery composition data to labelling, handling, transport, safety, and disclosure obligations that depend on formal hazard classification. It also affects how technical substance data is translated into compliance statements that customers, recyclers, and regulators can rely on.
For Minespider, hazardous substance is a reminder that battery data models cannot stop at product structure alone. Chemistry, legal classification, and downstream handling requirements all have to connect if compliance information is going to be accurate and usable.
