For the investigation so instituted, the Chief Administrative Law Judge, U.S.

International Trade Commission, shall designate the presiding Administrative Law Judge.
The Office of Unfair Import Investigations will not participate as a party in this
investigation.
The Commission is interested in the development of a thorough record on domestic
industry in this investigation to facilitate a holistic review of all relevant considerations.
Accordingly, the presiding administrative law judge may wish to consider what information will
be necessary to make a determination with respect to complainant’s domestic industry
allegations under subparagraphs (A), (B), and (C) of section 337(a)(3) based on an industry that
exists or is in the process of being established; including the extent to which these allegations
rely on expenditures made by third parties; and the extent to which expenditures are made
outside the United States related to the domestic industry article(s) by any entity.

Responses to the complaint and the notice of investigation must be submitted by the
named respondents in accordance with section 210.13 of the Commission’s Rules of Practice and
Procedure, 19 CFR 210.13. Pursuant to 19 CFR 201.16(e) and 210.13(a), such responses will be
considered by the Commission if received not later than 20 days after the date of service by the
Commission of the complaint and the notice of investigation. Extensions of time for submitting
responses to the complaint and the notice of investigation will not be granted unless good cause
therefor is shown.
Failure of a respondent to file a timely response to each allegation in the complaint and in
this notice may be deemed to constitute a waiver of the right to appear and contest the allegations
of the complaint and this notice, and to authorize the administrative law judge and the
Commission, without further notice to the respondent, to find the facts to be as alleged in the
complaint and this notice and to enter an initial determination and a final determination
containing such findings, and may result in the issuance of an exclusion order or a cease and
desist order or both directed against the respondent.
By order of the Commission.
Issued: October 9, 2026.

Lisa Barton,
Secretary to the Commission.
