The Prescription Drug User Fee Act (PDUFA) was created by Congress in 1992 and authorizes FDA to collect fees from companies that produce certain human drug and biological products. Since the passage of PDUFA, user fees have played an important role in expediting the drug approval process.

PDUFA must be reauthorized every five years, and was renewed in 1997 (PDUFA II), 2002 (PDUFA III), 2007 (PDUFA IV), and 2012 (PDUFA V) and 2017 (PDUFA VI). On August 18, 2017, the President signed into law the Food and Drug Administration Reauthorization Act (FDARA), which includes the reauthorization of PDUFA through September 2022. PDUFA VI will provide for the continued timely review of new drug and biologic license applications.

What is a human drug application?
PDUFA levies a user fee on certain human drug applications. Under PDUFA, the term human drug application means an application for

  • approval of a new drug submitted under section 505(b) of the Federal Food, Drug, and Cosmetic Act (FD&C Act), or
  • licensure of certain biological products under section 351(a) of the Public Health Service Act (PHS Act).
What are application fees?
Each person that submits a human drug application is assessed an application fee as follows:
  •  A human drug application for which clinical data (other than bioavailability or bioequivalence studies) with respect to safety or effectiveness are required for approval is assessed a full application fee.
  •  A human drug application for which clinical data with respect to safety or effectiveness are not required for approval is assessed one- half of a full fee.

Human drug application fees are due when the application is submitted.

Supplements with unpaid fees  submitted prior to PDUFA VI will not automatically be considered acceptable for filing once PDUFA VI takes effect in FY 2018.  Applicants may submit a new supplement in FY 2018 under PDUFA VI, which will not incur a supplement fee.

How do I pay a fee?
Visit our Payment Information and Cover Sheet tab for all the information you will need to pay your application fee.

Are there any exceptions to the fee requirements?

  • Previously Filed Applications: If an application
    • was submitted by a person that paid the fee for the application,
    • was accepted for filing, and
    • was not approved or was withdrawn (without a waiver),

The resubmission of the application for the same product (by the same person) does not require an application fee.

  • Designated Orphan Drug or Indication
    • An application for a prescription drug product that has been designated as a drug for a rare disease or condition, under section 526 of the Act, is not subject to an application fee unless the application includes an indication for other than a rare disease or condition.

For more information about application fees, please read FDA’s guidance for industry Assessing User Fees Under the Prescription Drug User Fee Amendments of 2017.

What are prescription drug program fees?
Prescription drug product program fees are assessed annually for eligible products. The program  fees are assessed for each prescription drug product that is identified in such a human drug application approved as of October 1st of such fiscal year. 

Applicants may not be assessed more than five prescription drug program fees for a fiscal year for prescription drug products identified in a single approved application.

What is the definition of a prescription drug product?
Prescription drug product means a specific strength or potency of a drug in final dosage form for which a human drug application has been approved and which may be dispensed only by prescription under section 503(b) of the FD&C Act, and is also on the list of products described in section 505(j)(7)(A), or is on a list created and maintained by the Secretary of products approved under human drug applications under section 351 of the Public Health Service Act.

Are there drugs that are not included in the term prescription drug product?
Yes. The term prescription drug product does not include the following drugs:

  • Whole blood or a blood component for transfusion
  • A bovine blood product for topical application licensed before September 1, 1992, an allergenic extract product, or an in vitro diagnostic biologic product licensed under section 351 of the PHS Act  A biological product that is licensed for further manufacturing use only
  • A drug that is not distributed commercially AND is the subject of an application or supplement submitted by a State or Federal Government entity

How do I pay a fee?
Visit our Payment Information and Cover Sheet tab for all the information you will need to pay your product fee.  

Are there any exceptions to the fee requirements?

  •  listed in the Orange book with a potency described in terms of per 100 mL, or,
  •  the same product as another product approved under

When are user fees due?

  • An application fee is due when the application is submitted to FDA.
  • FDA issues invoices for annual program fees for the coming fiscal year in August of each year using the fee schedule for the coming fiscal year. Payments are due either on the first business day on or after October 1 of each fiscal year or the first business day after the enactment of an appropriations Act providing for the collection and obligation of fees for that fiscal year, whichever occurs later.
  • FDA may issue additional invoices as needed. These invoices are also known as clean-up invoices to capture program fees that were not previously invoiced. The clean-up invoices are generally issued in mid-December of the fiscal year and the fees are generally due by mid-January of the fiscal year.

What is the Federal government's fiscal year?
The Federal government's fiscal year begins on October 1 and ends on September 30. For example, fiscal year 2019 begins October 1, 2018, and ends September 30, 2019. Fiscal year 2018 begins October 1, 2017 and ends September 30, 2018.

What is the PDUFA User Fee Cover Sheet?
Form FDA 3397, the PDUFA user fee cover sheet, is designed to provide the minimum necessary information to determine whether a fee is required for review of an application, to determine the amount of the fee required, and to help FDA track payments. The PDUFA Cover Sheet Form FDA 3397 should be completed for the following:

  • 505(b) and 351(a) Original Applications
  • Resubmission of 505(b) and 351(a) Original Application after a Refuse to File
  • Resubmission of 505(b) and 351(a) Original Applications Withdrawn before the filing date.

The form provides a cross-reference of the fee submitted for an application with the actual application by using a unique number tracking system to assign the user fee payment identification number (PIN). The information collected is used by FDA's Center for Drug Evaluation and Research (CDER) and Center for Biologics Evaluation and Research (CBER) to initiate the administrative screening of new drug applications and biologics license applications. Note: You do not need to fill out a Form 3397 for annual program fee payments.

Are there any waivers of user fees?
Under section 736(d) of the FD&C Act, a waiver may be granted for one or more fees where:

  • the applicant involved is a small business submitting its first human drug application for review

Is there a reduction of fees for human drug applications that are refused for filing or are withdrawn before or after filing?
Yes. The following reductions or refunds are available:

To be granted a waiver, the human drug applicant must submit a written request for the waiver.

To qualify for consideration, a written request for waiver, reduction or refund must be submitted not later than 180 days after such fee is due.
