An application that proposes using an enriched isomer of an active ingredient, where such enriched isomer is not currently contained as an active ingredient in any U.S. registered pesticide product. This category consists of active ingredients that are a variation on the molecular structure or composition of a registered product and which will cite at least some of the generic data conducted with a registered product. If a food use is included in this new active ingredient package, the use may require the establishment of or the exemption from the requirement of a tolerance under section 408 of the FFDCA. If a tolerance or exemption from the requirement of a tolerance is required, the application submission must contain     a petition to establish tolerances or exemption(s) from tolerance for all food/feed commodities covered by the pending registration application. All uses (food and non-food) included in the original application or petition for each new active ingredient are covered by the base fee for the application in this category if submitted in this package.

All of the inerts used in the product must be either approved, pending with the Agency, or a new inert is submitted within the package for the applicable uses.

A maximum of five new products are covered by the base fee. After the first five new products, each application for an additional new product or new inert ingredient approval that is submitted within this new active ingredient package is subject to the registration service fee for a new product or a new inert ingredient approval. All such associated applications that are submitted together will be subject to the new active ingredient decision review time.

Until the new active ingredient is approved, any subsequent application for another new product containing the same active ingredient or an amendment to the proposed labeling will be charged a new active ingredient service fee and decision review timeframe.

If the applicant on his own initiative submits any additional information that was neither requested nor required by the Agency, after completion of the technical deficiency screening, and which does not itself constitute a covered registration application, the applicant will be charged an additional 25% of the full registration service fee for the new active ingredient application.

The Agency will provide the applicant with a pre-decisional determination 4 weeks prior to the PRIA decision review time due date which specifies any label changes that have to be made in order to grant the requested new active ingredient registration. If the label issues cannot be resolved prior to the PRIA decision review time due date and if a PRIA due date time extension has not been agreed upon, then the Agency will issue to the applicant its regulatory decision with the specific label changes and supporting documentation on or just before the PRIA decision review time due date. At that time the applicant must either (a) agree to all of the label changes and submit a revised label that incorporates all of these label changes; or (b) does not agree with one or more of the label changes and request up to 30 days to reach agreement with the Agency and submit a revised label that incorporates all of the agreed upon label changes, which the Agency has 2 business days to review; or (c) withdraw the application without prejudice.
