What does the first part of an EPA registration number typically identify?

The first part of an EPA registration number is specifically used to identify the manufacturer or company that is responsible for the product. This unique identifier serves to ensure that all pesticides are traceable back to their source, which is essential for maintaining safety and accountability in pesticide management and regulation. It allows regulatory agencies and consumers to know who is producing and distributing the product, facilitating easier communication and regulation compliance.

This identification system is crucial for regulatory oversight, as it helps the EPA track pesticide products through the registration process and allows for easier handling of any safety issues or recalls that may arise. The remaining aspects of the registration number, such as product identification, distributor information, and facility location, follow after the initial manufacturer identifier, but the primary focus of the first part is to clearly identify the manufacturing entity.
