Inert Ingredients in Pesticide Products - About Tolerance Reassessment

EPA sets limits on the amount of pesticides that may remain in or on foods. These limits are called tolerances. The tolerances are set based on a risk assessment and are enforced by the Food and Drug Administration and the United States Department of Agriculture. More information on tolerances is provided at Pesticide Tolerances. EPA has reassessed tolerances (chemical residue limits in food) and exemptions from tolerances for inert ingredients in pesticide products to ensure that they met the safety standard established by the Food Quality Protection Act (FQPA) in 1996.

FQPA required the reassessment of inert ingredient tolerances and tolerance exemptions that were in place prior to August 3, 1996. In 2006, EPA completed the reassessment of inert ingredients. Completed inert ingredient tolerance reassessment decision documents are now available on the Tolerance Reassessment Decision Document page.

Refer to the US Government Printing Office issued Code of Federal Regulations (CFR) for complete and current information on Categorized List of Inert (other) Pesticide Ingredients. The CFR describes how each inert ingredient may be used.
