About Pesticide Registration Fees under PRIA

FIFRA amendments passed by Congress in 2004 created a registration service fee system for applications for specific pesticide registration, amended registration, and associated tolerance actions. The goals of this fee system are to:

• create a more predictable evaluation process for affected pesticide decisions, and
• couple the collection of individual fees with specific decision review periods.

The 2004 amendments are also known as the Pesticide Registration Improvement Act of 2003 (PRIA).

PRIA has been reauthorized four times, the most recent being the Pesticide Registration Improvement Act of 2022 (PRIA 5). This reauthorization is effective through September 30, 2027.

PRIA established Section 33 of FIFRA. The amendments are reflected in the current version:

See FIFRA Section 33--Pesticide Registration Service Fees (also cited as U.S. Code Title 7, Chapter 6, Subchapter II, Section 136w-8). 

Actions subject to fees are categorized:

• First by type of chemical:
  • Conventional.
  • Antimicrobial.
  • Biopesticide.
  • Inert ingredients.

• Next by the type of action:
  • New active ingredient.
  • New use.
  • Import and other tolerances.
  • New products.
  • Amendments.
  • Miscellaneous.

Under this system, each individual category corresponds to a certain registration service fee and decision review period.

The fees and decision review periods may change from one fiscal year to the next, and fees are periodically increased as prescribed by statute. Applicants should refer to the fee determination decision tree or fee table for assistance in finding the appropriate PRIA category and fee for their submission.
