What Does SNUR Stand For?

SNUR stands for Significant New Use Rule

The Significant New Use Rule (SNUR) is a regulatory mechanism under the Toxic Substances Control Act (TSCA) that requires manufacturers and importers to notify the Environmental Protection Agency (EPA) before commencing a new use of certain chemicals. This rule aims to ensure that potential risks associated with new uses are evaluated, allowing the EPA to assess and mitigate any adverse effects on human health and the environment. SNURs are typically applied to chemicals that have undergone a risk assessment and are subject to specific requirements to safeguard public safety.
