FIFRA 25(b) Minimum Risk Pesticides: U.S. EPA Federal Registration Exemption Explained

Introduction


When exporting pesticides to the U.S., the traditional federal registration process often involves significant review fees and lengthy approval times, often measured in years. However, the U.S. Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) provides a more efficient pathway for certain low-risk products. 

Products that meet the criteria of Section 25(b) may qualify for an exemption from U.S. EPA federal pesticide registration, allowing them to enter the market as FIFRA 25(b) minimum risk pesticides.


What are FIFRA 25(b) Minimum Risk Pesticides?


Minimum risk pesticides refer to products whose active ingredients and inert ingredients are both listed on the U.S. Environmental Protection Agency (EPA)’s approved lists and pose minimal risks to human health and the environment under normal use conditions. These products often use naturally-derived plant extracts as active ingredients, such as citronella oil, peppermint oil, and garlic oil. Their modes of action are relatively mild, primarily aimed at repelling or inhibiting pests rather than high-toxicity insecticidal or disinfectant purposes.

Under Section 25(b) of FIFRA, minimum risk pesticides are exempt from federal registration requirements with the U.S. EPA. This means that the products do not need an EPA Registration Number (EPA Reg. No.) to comply with federal-level regulations.

Note: While 25(b) products are exempt from federal registration, most states still require state-level registration or notification before they can be sold in that state.

Compliance Requirements for FIFRA Section 25(b) Registration Exemptions


A common misconception among companies is equating “federal registration exemption” with “regulatory relaxation.” In fact, 25(b) minimum risk pesticides must still meet strict compliance requirements, including:

  • Ensuring the product formulation falls within the regulatory allowances

  • Providing complete, truthful, and compliant labeling information

  • Avoiding health or public health claims in marketing materials

  • Ensuring accurate company and product claims

Additionally, the vast majority of U.S. states still require state-level registration or notification for 25(b) minimum risk pesticides. Failing to meet state-level compliance could result in product recalls, hefty administrative fines, damage to brand reputation, or even blacklisting by regulatory authorities.
