On May 10, 2021, the U.S. Environmental Protection Agency (EPA) announced the launch of an electronic Confidential Statement of Formula application (eCSF builder) to support pesticide registration applications. The new electronic tool is part of EPA’s interest in improving and modernizing the internal processes and digital workflows for pesticide registration submissions.

As part of the registration process for new pesticide products, EPA requires the submission of a Confidential Statement of Formula (CSF). The form lists all the product’s components and percent by weight, along with various additional information.

Currently, CSF applications must be submitted to EPA in hard copy. The new eCSF builder will automatically validate certain data in a CSF application prior to submission to EPA. EPA states this functionality, along with real-time validation of chemical ingredients through EPA’s Substance Registry Services, will make the pesticide registration process more efficient, saving EPA and registrants time and resources. While paper CSF forms remain available, EPA encourages submitting applications electronically, as the review of paper applications could be a longer process.

Users can access the eCSF builder on the Central Data Exchange (CDX) under Pre-Submission Tools, Form Builders, by clicking the Create eCSF button. Users can provide feedback to EPA through the CDX.
