Petition Technical Assistance for TAA Practitioners

Petition technical assistance resources go beyond the petitioner informationpetition process, and frequently asked questions.  It is designed to cover advanced topics such as amendment processes, staffed workers (leased workers), how to read a Trade Adjustment Assistance (TAA) determination, International Trade Commission (ITC) determinations, and other topics.  Some materials are currently under construction.

Filing a TAA Petition

Basic information on TAA petition filing can be found in the petitioner information, petition process, and frequently asked questions.  Review this tip document for additional information on compliant and/or efficient petition filing.  It is important to ensure that company official information is valid and complete as missing or incomplete information may make the petition invalid or cause significant investigation delays.  Practitioners are encouraged to submit a petition online as this provides confirmations of transmission, provides copies to state agencies, and speeds petition intake.

Helping Firms with the Petition Process

The active involvement of firms in the TAA petition process is important to issuing timely and accurate decisions.  We encourage TAA practitioners to work with firms as early as possible.  Under the Company Officials page, companies can find an orientation video to the TAA process as well as sample forms so they know what to expect.


To better understand when and how investigation updates are communicated to petitioners, officials, and state officials, a list of when those communications occur can be found here.


When there is a change in ownership over a TAA-certified worker group, states must determine whether the new firm is a successor-in-interest that allows workers newly threatened or separated to still qualify.  This infographic outlines the process for states to make this determination.  Find the associated webcast on WorkforceGPS.


Amendments are used to correct determinations, clarify worker groups, or other modifications.  Amendments may only adjust current certifications.  To request an amendment, submit a petition and explain the need for the amendment in the Trade Effects section.  Please include the TAW number of the certification that the request is seeking to amend.  Because eligibility periods are set by statute, amendments may not extend a certification's expiration date.  Instead, a new petition must be filed for any layoffs occurring after the expiration of a certification.


The process for requesting a reconsideration is discussed in the "How to Challenge a Petition Denial" section of the Understanding the Process page.

International Trade Commission (ITC) Determinations

One basis for TAA certification is that the ITC identified a firm by name as a member of a domestic industry under certain affirmative determinations under the Trade Act.  TAA certifications under this provision have unique periods of eligibility and do not cover threatened workers.  You can find details about the petition process and differences in eligibility in our webinar on the topic and accompanying FAQ sheet.
