Inert Ingredients Eligible for FIFRA 25(b) Pesticide Products
Last Updated December 20, 2010
Provided below are the inert ingredients that are eligible for inclusion in pesticide products
under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)'s Section 25(b).
This listing of minimal risk inert ingredients updates what has been historically referred to
as "4A" under Pesticide Registration Notice 2000-6.
1. Commonly consumed food commodities, animal feed items, and edible fats and oils as described
in 40 CFR 180.950(a), (b), and (c) may be used as inert ingredients in FIFRA Section 25(b) pesticide
products applied to food use sites (e.g., food crops, animals used for food) and in FIFRA Section
25(b) pesticide products applied to nonfood use sites (e.g., ornamental plants, highway right-of-
ways, rodent control). Specific chemical substances listed under 40 CFR 180.950(e) that are also
acceptable for use as inert ingredients in FIFRA Section 25(b) pesticide products are included in the
table below.
2. In addition to (1) above, the following inert ingredients are also eligible for inclusion in FIFRA
Section 25(b) pesticide products. These ingredients are listed by CAS Registry Number and
chemical name (common names are given, with systematic names included as synonyms in brackets
where applicable). In addition, this listing has two columns to indicate whether the inert ingredient
can be used in FIFRA Section 25(b) products applied to food use and/or nonfood use sites.
