---------------------------------------------------------------------------

Methodology

    Commerce is conducting this investigation in accordance with 
section 731 of the Act. Commerce has calculated export prices in 
accordance with section 772(a) of the Act. Normal value is calculated 
in accordance with section 773 of the Act. Pursuant to section 776(a) 
and (b) of the Act, Commerce has preliminarily relied upon facts 
otherwise available, with adverse inferences, for Formosa Asahi Spandex 
Co., Ltd (FAS). For a full description of the methodology underlying 
the preliminary determination, see the Preliminary Decision Memorandum.

All-Others Rate

    Sections 733(d)(1)(ii) and 735(c)(5)(A) of the Act provide that in 
the preliminary determination, Commerce shall determine an estimated 
all-others rate for all exporters and producers not individually 
examined. This rate shall be an amount equal to the weighted average of 
the estimated weighted-average dumping margins established for 
exporters and producers individually investigated, excluding any zero 
and de minimis margins, and any margins determined entirely under 
section 776 of the Act.
    In this investigation, Commerce preliminarily assigned a rate based 
entirely on adverse facts available to FAS. Therefore, the only rate 
that is not zero, de minimis or based entirely on facts otherwise 
available is the rate calculated for Dairen Chemical Corporation 
(Dairen). Consequently, the rate calculated for Dairen is also assigned 
as the rate for all other producers and exporters.

Preliminary Determination

    Commerce preliminarily determines that the following estimated 
weighted-average dumping margins exist:

------------------------------------------------------------------------
                                                               Estimated
                                                               weighted-
                                                                average
                      Exporter/producer                         dumping
                                                                margin
                                                               (percent)

------------------------------------------------------------------------
* Rate based on facts available with adverse inferences.

Suspension of Liquidation

    In accordance with section 733(d)(2) of the Act, Commerce will 
direct U.S. Customs and Border Protection (CBP) to suspend liquidation 
of entries of subject merchandise, as described in Appendix I, entered, 
or withdrawn from warehouse, for consumption on or after the date of 
publication of this notice in the Federal Register. Further, pursuant 
to section 733(d)(1)(B) of the Act and 19 CFR 351.205(d), Commerce will 
instruct CBP to require a cash deposit equal to the estimated weighted-
average dumping margin or the estimated all-others rate, as follows: 
(1) the cash deposit rate for the respondents listed above will be 
equal to the company-specific estimated weighted-average dumping 
margins determined in this preliminary determination; (2) if the 
exporter is not a respondent identified above, but the producer is, 
then the cash deposit rate will be equal to the company-specific 
estimated weighted-average dumping margin established for that producer 
of the subject merchandise. These suspension of liquidation 
instructions will remain in effect until further notice.

Disclosure

    Commerce intends to disclose its calculations and analysis 
performed to interested parties in this preliminary determination 
within five days of any public announcement or, if there is no public 
announcement, within five days of the date of publication of this 
notice in accordance with 19 CFR 351.224(b).
    Consistent with 19 CFR 351.224(e), Commerce will analyze and, if 
appropriate, correct any timely allegations of significant ministerial 
errors by amending the preliminary determination. However, consistent 
with 19 CFR 351.224(d), Commerce will not consider incomplete 
allegations that do not address the significance standard under 19 CFR 
351.224(g) following the preliminary determination. Instead, Commerce 
will address such allegations in the final determination together with 
issues raised in the case briefs or other written comments.

Verification

    As provided in section 782(i)(1) of the Act, Commerce intends to 
verify the information relied upon in making its final determination.

    \9\ We use the term ``issue'' here to describe an argument that 
Commerce would normally address in a comment of the Issues and 
Decision Memorandum.
    \10\ See APO and Service Procedures.
---------------------------------------------------------------------------

    Pursuant to 19 CFR 351.310(c), interested parties who wish to 
request a hearing, limited to issues raised in the case and rebuttal 
briefs, must submit a written request to the Assistant Secretary for 
Enforcement and Compliance, U.S. Department of Commerce, within 30 days 
after the date of publication of this notice. Requests should contain: 
1) the party's name, address, and telephone number; 2) the number of 
participants and whether any participant is a foreign national; and 3) 
a list of the issues to be discussed. If a request for a hearing is 
made, Commerce intends to hold the hearing at a time and date to be 
determined. Parties should confirm by telephone the date, time, and 
location of the hearing two days before the scheduled date.

Postponement of Final Determination and Extension of Provisional 
Measures

    Section 735(a)(2) of the Act provides that a final determination 
may be postponed until not later than 135 days after the date of the 
publication of the preliminary determination if, in the event of an 
affirmative preliminary determination, a request for such postponement 
is made by exporters who account for a significant proportion of 
exports of the subject merchandise, or in the event of a negative 
preliminary determination, a request for such postponement is made by 
the petitioner. Section 351.210(e)(2) of Commerce's regulations 
requires that a request by exporters for postponement of the final 
determination be accompanied by a request for extension of provisional 
measures from a four-month period to a period not more than six months 
in duration.
    On August 20, 2026, pursuant to 19 CFR 351.210(e), Dairen requested 
that Commerce postpone the final determination and that provisional 
measures be extended to a period not to exceed six months.\11\ In 
accordance with section 735(a)(2)(A) of the Act and 19 CFR 
351.210(b)(2)(ii), because: (1) the preliminary determination is 
affirmative; (2) the requesting exporter accounts for a significant 
proportion of exports of the subject merchandise; and (3) no compelling 
reasons for denial exist, Commerce is postponing the final 
determination and extending the provisional measures from a four-month 
period to a period not greater than six months. Accordingly, Commerce 
will make its final determination no later than 135 days after the date 
of publication of this preliminary determination.
---------------------------------------------------------------------------

    \11\ See Dairen's Letter, ``Request to Postpone the Final 
Determination,'' dated September 8, 2026.
---------------------------------------------------------------------------

U.S. International Trade Commission (ITC) Notification

    In accordance with section 733(f) of the Act, Commerce will notify 
the ITC of its preliminary determination of sales at LTFV. If the final 
determination is affirmative, the ITC will determine before the later 
of 120 days after the date of this preliminary determination or 45 days 
after the final determination whether these imports are materially 
injuring, or threaten material injury to, the U.S. industry.

Notification to Interested Parties

    This determination is issued and published in accordance with 
sections 733(f) and 777(i)(1) of the Act, and 19 CFR 351.205(c).

    Dated: November 4, 2026.

Duty Operations.

Appendix I

Scope of the Investigation

    The merchandise covered by the investigation is 
polytetramethylene ether glycol (PTMEG), which is a polymer 
consisting of linear diols (i.e., organic chemical compound that has 
two hydroxyl (- OH) functional groups) with a molecular backbone of 
repeating tetramethylene units (- CH2CH2CH2CH2-) interconnected 
through ether bonds (i.e., a single oxygen atom bonded to two carbon 
atoms), with a chemical formula HO{(CH2)4{time} nOH. PTMEG is also 
referred to as Polytetrahydrofuran, PTHF, Polytetramethylene ether 
glycol, PTMG, and Polybutylene glycol. PTMEG is typically blended 
with butylated hydroxytoluene (BHT) or another stabilizer such as 
higher molecular weight hindered phenols or phosphoric acid. In 
addition to a stabilizer, PTMEG is sometimes blended with a modifier 
or additive, such as phosphoric acid or sulfuric acid. The scope 
includes all blends consisting of PTMEG and stabilizers, modifiers, 
and/or additives, where the stabilizers, modifiers, and/or additives 
collectively account for no more than two percent of the total 
weight of the PTMEG blend. PTMEG is normally associated with 
Chemical Abstracts Service (CAS) registry number 25190-06-1.
    The scope includes all forms of PTMEG, regardless of physical 
form, purity, molecular weight, number of hydroxyls, number of 
acids, color, density, softening point, glass transition point, 
flash point, water content, viscosity, and packaging. PTMEG that has 
been blended with other products is included within this scope when 
such blends include constituent parts that have been intermingled 
but that have not been chemically reacted with each other to produce 
a different product. For such blends, only the PTMEG component of 
the mixture, inclusive of any stabilizers, modifiers, and/or 
additives collectively accounting for no more than two percent of 
the combined weight of the PTMEG component and the stabilizers, 
modifiers, and/or additives, is covered by the scope of the 
investigation.
    The scope includes merchandise matching the above description 
that has been processed in a third country, including by 
commingling, diluting, introducing, or removing stabilizers, 
modifiers, or additives, or performing any other processing that 
would not otherwise remove the merchandise from the scope of the 
investigation if performed in the subject country. The scope also 
includes PTMEG that is commingled or blended with PTMEG from sources 
not subject to the investigation. Only the subject component of such 
commingled products is covered by the scope of the investigation.
    The subject merchandise is classifiable in the Harmonized Tariff 
Schedule of the United States (HTSUS) under subheading 3907.29.0000. 
Subject merchandise may also be imported under HTSUS subheadings 
2932.11.0000 and 3404.90.5150. Although the HTSUS subheading and CAS 
registry number are provided for convenience and customs purposes, 
the written description of the scope is dispositive.
