An application for registration of an end-use or a manufacturing use microbial or biochemical pesticide product that is substantially similar, identical in its uses and formulation, or that differs only in ways that would not significantly increase the risk of unreasonable adverse effects on the environment to products that are currently registered and, which contains a registered source of active ingredient. If the proposed new product contains an unregistered source of active ingredient, then see category B672. The applicant must identify the similar registered products for all active ingredients in the proposed product. All applications require the following:

• A data matrix is required with the application if it is not a 100% re-packaged product.
• Product chemistry data (Group A and B) unless the product is identical (e.g., 100% repackaged product). In some cases, product chemistry data can be satisfied as outlined in Pesticide Registration Notice 98-1.
• The active ingredient(s) must be currently registered and the CSF must include its EPA Registration Number(s).
• In all cases, the registrant must identify the registered similar product for this category.
• Acute toxicity requirements must be addressed by using:
  1. The cite-all method
  2. Selective data citation where the applicant owns all required data, or
  3. Applicant submits specific authorization letter from the data owner

The application is not in this category if efficacy, acute toxicity, companion animal safety, and/or child resistant packaging data are submitted and must be reviewed to support the application. The application does not fall into this category if it contains a request to waive any of these data. An application that requires review of cited or submitted data other than product chemistry does not belong in this fee category. If the use pattern on the TGAI differs from the proposed products, then additional data are required and the application does not fall within this category.

Substantially similar: Product must have the same active ingredient, in substantially the same proportion, same chemical composition (solid, liquid, granular), and substantially similar inert ingredients as the already registered product. In addition, substantially similar means that the proposed product bears the same use pattern. Adding to or changing existing use patterns excludes the proposed product from treatment as a substantially similar product. Deleting use patterns is acceptable.

Identical: Same composition and use patterns as a currently registered end-use product.

Manufacturing Use Product: A 100% re-package of a manufacturing use product that requires no data submission or data matrix is covered by this category.

An application for a new end-use product using a source of active ingredient that is not yet registered but has an application pending with the Agency for review, will be considered an application for a new product with an unregistered source of an active ingredient.
