The U.S. Environmental Protection Agency (EPA) has issued a final Significant New Use Rule (SNUR) under TSCA for substances including graphene nanoplatelets. Anyone intending to manufacture (including import) or process graphene nanoplatelets for designated "significant new use" must notify EPA at least 90 days in advance via Significant New Use Notice (SNUN).
This process allows the agency to evaluate potential risks before new activities begin.
