Summary
The US Environmental Protection Agency (EPA) has finalized Significant New Use Rules (SNURs) under the Toxic Substances Control Act (TSCA) for the chemical substance "edge oxidised graphene," identified as "edge oxidized carbon matrix" (PMN P–22–114). The new regulation requires manufacturers and processors to notify the EPA at least 90 days in advance of commencing activities defined as "significant new uses."
For edge oxidised graphene, the SNUR addresses workplace protection, hazard communication, manufacturing conditions, and releases to water. The rule also specifies circumstances where its requirements do not apply, such as when the substance is incorporated into an article or entrained in a cured coating. The finalized rule becomes effective on 26 October 2026. Companies involved in the manufacturing, import, or processing of the specified substance should review the SNUR and associated requirements.
