The content of each column in the Tolerance Reassessment Status table is described below:

Inert Ingredient

The inert ingredient’s name as it appears in the Code of Federal Regulations (CFR).

CAS Reg. No. and Name

The inert ingredient’s CAS Registry Number is the unique identification number that the Chemical Abstracts Service (CAS) has assigned to the chemical substance.

Chemical substances often have multiple names. In addition to the inert ingredient’s name that appears in the CFR, EPA utilizes the CAS 9th Collective Index Name, which is the systematic chemical name associated with the CAS Registry Number.

Decision Documents

Reassessment decision documents for each inert ingredient are provided here. A decision document includes the risk assessments and the decision memo. Please note that several inert ingredients may be grouped in a document.

Reassessed Date

The date the decision memo was signed and the inert ingredient completed tolerance reassessment.

CFR Citations

How each inert ingredient may be legally used in food-use pesticide products is described in the Code of Federal Regulations (CFR). Up-to-date CFR citations are found at U.S. Government Printing Office website.
