What does an "EPA registration number" signify?

An "EPA registration number" signifies that the product has undergone evaluation and approval by the Environmental Protection Agency (EPA). This number serves as a unique identifier for pesticides and certain other regulated products, indicating that they have been assessed for safety, effectiveness, and environmental impact before being marketed to the public. The registration process ensures that the product meets specific regulatory standards, thus providing assurance to consumers and applicators about its appropriateness for its intended use.

The presence of an EPA registration number does not imply that a product contains only natural ingredients, guarantees safety under all conditions, or indicates that the product is biodegradable. These factors are evaluated separately and do not form the basis for EPA registration, which focuses primarily on the safety and efficacy of the product in terms of its effects on human health and the environment.
