Inert (other) Pesticide Ingredients in Pesticide Products - Categorized List of Inert (other) Pesticide Ingredients

Inert Resources

Inerts Ingredient Assessment Branch, Inerts Team

For an inert ingredient to be included in a food-use pesticide product, a tolerance exemption must be established in the appropriate section of 40 CFR 180 subpart D.

Categorized Lists - OPP published a policy statement on inert ingredients in 1987. 52 FR 13305, Inert Ingredients in Pesticide Products Policy Statement (04/22/87)). The policy established four categories of toxicological concern for the inert ingredients in existence at that time. In 1989, List 4 "Inerts of Minimal Concern" was subdivided into List A and List 4B (see 54 FR 48314, Inert Ingredients in Pesticide Products; Policy Statement; Revision and Modification List (11/22/89)).
