Indexes to Part 180 Tolerance Information for Pesticide Chemicals in Food and Feed Commodities
Current as of July 2010
This Web page describes information that may be helpful in finding specific pesticide tolerance information available in the Code of Federal Regulations (CFR) at Part 180. The pesticide tolerance information provided in the index pdf files below are intended to help registrants, scientists, importers, trade associations, extension agents identify:
- Tolerances (maximum residue levels) or exemptions from tolerance requirements for a food or feed commodity.
- Pesticide chemicals that belong to a particular commodity, crop group, or crop subgroup.
- Pesticide chemicals that belong to a particular pesticide type or pesticide family.
Note: Pesticide tolerance information is updated in the Code of Federal Regulations on a weekly basis. EPA plans to update the index pdf files on this webpage biannually. These index files are current as of the date indicated in the pdf file. For the latest information on pesticide tolerances, please refer to the electronic Code of Federal Reguations (eCFR).

Additional Information
Commodities, Crop Groups, and Crop Subgroups
A commodity is any unprocessed or partially processed good, such as grains, fruits, and vegetables.
For tolerance purposes, a crop group is a group of crops that are botanically or taxonomically related. Tolerances for a crop group are based on residue data from representative crops (normally major crops) within the group.
A crop group may be further subdivided into crop subgroups; these are smaller and more closely related crop groupings. The representative commodities for each subgroup are also a smaller subset of those for the “parent” group.
Pesticide Types and Families
Pesticides are often categorized based on the type of pest they control. For example, the pesticide type "herbicides" kill weeds and other plants that grow where they are not wanted. Pesticides are also categorized by the chemical family to which they belong; these families are based on similarities in chemical structures, modes of action, and chemical properties. For example, malathion, parathion, and phosaline belong to the pesticide family "organophosphorus."
What does "Reserved" and "Not Found" mean in the index pdf files?
"Reserved" is used by the Federal Register to indicate the section, e.g., 180.373, is available for tolerance information pertaining to a new pesticide chemical.
"Not Found" indicates that the information was not readily available from the sources used to supplement the existing information in the alphabetical finding aid in the July 1, 2007, edition of 40 CFR part 180.
Title 40 of the Code of Federal Regulations
- tolerances for different agricultural commodities;
- time-limited tolerances (such as Section 18 exemptions);
- tolerances with regional limitations; and
- indirect or inadvertent residues.
When viewing these index pdf files, you will be directed to the detailed pesticide tolerance information in Title 40 of the Code of Federal Regulations (40 CFR). The detailed information for each pesticide residue and its metabolites includes:
