Here is a phone number from BaNosser's post: (202) 205-2000.Mention "inv. no 337-TA-853". Also note that there is a web address or ? listed as EDIS. If not available I would guess it was requested to be confidential. Although if they didn't send electronically and send hard "true" copies the next day .... whoops, and we may see something.
Also here's copy from BaNosser's post :
"All such requests should be
directed to the Secretary to the
Commission and must include a full
statement of the reasons why the
Commission should grant such
treatment. See 19 CFR 201.6. Documents
for which confidential treatment by the
Commission is properly sought will be
treated accordingly. A redacted non-
confidential version of the document
must also be filed simultaneously with
any confidential filing. All non-
confidential written submissions will be
available for public inspection at the
Office of the Secretary and on EDIS.
The target date for completion of this
investigation is extended to January 29,
2014.
The authority for the Commission’s
determination is contained in section
337 of the Tariff Act of 1930, as
amended (19 U.S.C. 1337), and in
sections 210.42–46 and 210.50 of the
Commission’s Rules of Practice and
Procedure (19 CFR 210.42–46 and
210.50).
By order of the Commission.
Issued: November 25, 2013."
