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.

Extensions of time for submitting responses to the complaint and the notice of investigation will not be granted unless good cause therefor is shown. ( printed page 65256)

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.
