Regulatory Oversight
The Office of Indiana State Chemist (OISC) is resonsible for registering pesticide products in the state of Indiana.
- According to I.C. 15-16-4-61 each pesticide product that is produced, distributed, sold, displayed, offered for sale, or transported through the state requires registration before any of these activities can take place.
- A pesticide is a substance or mixture of substances intended to prevent, destroy, repel, or mitigate a pest. Herbicides, insecticides, fungicides, disinfectants, rodenticides, and repellents are examples of pesticides.
- A pesticide product, in accordance with I.C. 15-16-4-33, includes pesticides and pesticide devices.
- I.C. 15-16-4-10 defines a pesticide device as any instrument or contrivance intended for trapping, destroying, repelling, or mitigating any pest.
All pesticide products are regulated by the U.S. Environmental Protection Agency (EPA) under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA).
Pesticide Product State Registrations
Pesticide products fall under multiple types and the process to register them in the state of Indiana differs for each type:
- Section 3 Registrations - products federally registered under Section 3 of FIFRA.
- 25(b) Minimum Risk – products exempt from federal registration but have specific required regulations.
- Pesticide Devices – products are not registered federally but are subject to regulations under FIFRA. Includes some pheromone and lure traps.
- Experimental Use – experimental use permits provided to test pesticides under development. Federal registration or exemption under FIFRA Section 5.
- Special State Registrations – labels for specific use in the state of Indiana include FIFRA Section 24(c) and Section 18.
Annual Product Renewals
- All pesticide products must be renewed prior to January 1st of the next year.
Registered Products in the State
- All state registered products can also be reviewed at the following websites:
If you cannot locate a product on any of the available search options, it is likely that the product is not registered in the state of Indiana. You are welcome to contact our office if you would like to confirm the registration or RUP status of any product.
Label Submission Requirements
OISC no longer accepts paper labels. Labeling should be submitted to the office either by e-mail (
All elements of the container labels must be submitted as one PDF file. This means that if the labeling includes a portion of the label that is adhered to the container and a booklet, this must all be combined in one PDF file. This also applies for devices where the labeling on the box, directions for use (owner’s manuals), and any labeling on the physical device must all be in one PDF file.
Labels must be text-searchable and free of printer proof markings.
Revised Label Submission Requirements
Revised labels follow the directions above for Label Submission Requirements. In addition, if the labels are submitted via email, the PDF document must be named to match the 10-digit IN REG Number of the product. This number is the first column on the renewal listing.
Revised labels must also be accompanied by a list of changes and/or revisions.
What Requires Separate Registration
According to IC 15-16-4-56: "For more than one (1) pesticide product to be considered the same pesticide product, each pesticide product must exhibit the same: (1) product name; (2) registrant name; (3) United States Environmental Protection Agency registration number; (4) labeling, claims, and branding; and (5) ingredient statement."

Product Registration and Certificate
OISC does not mail pesticide product registration certificates. However, the applicant will receive an automated e-mail from our database when the product has been registered or renewed. After registration, the product can be legally sold, distributed, or used within the state of Indiana.
State registered products can be searched at either website listed below. For Indiana Restricted Use Products, these will be identified within the product name in parenthesis.
