SUMMARY: The U.S. Department of Commerce (Commerce) preliminarily 
determines that certain monomers and oligomers (monomers and oligomers) 
from the Republic of Korea (Korea) are being, or are likely to be, sold 
in the United States at less than fair value (LTFV). The period of 
investigation (POI) is January 1, 2024, through December 31, 2024. 
Interested parties are invited to comment on this preliminary 
determination.

DATES: Applicable January 5, 2026.

SUPPLEMENTARY INFORMATION:

Background

    This preliminary determination is made in accordance with section 
733(b) of the Tariff Act of 1930, as amended (the Act). Commerce 
published the notice of initiation of this investigation on April 23, 
2025.\1\ On August 19, 2025, Commerce postponed the preliminary 
determination of this investigation.\2\

Korea: Postponement of Preliminary Determination in the Less-Than-
Fair-Value Investigation, 90 FR 40330 (August 19, 2025).
---------------------------------------------------------------------------

    Due to the lapse in appropriations and Federal Government shutdown 
on November 14, 2025, Commerce tolled all deadlines in administrative 
proceedings by 47 days.\3\ Additionally, due to a backlog of documents 
that were electronically filed via Enforcement and Compliance's 
Antidumping and Countervailing Duty Centralized Electronic Service 
System (ACCESS) during the Federal Government shutdown, on November 24, 
2025, Commerce tolled all deadlines in administrative proceedings by an 
additional 21 days.\4\ Accordingly, the deadline for this determination 
is now December 30, 2025.

Methodology

    Commerce is conducting this investigation in accordance with 
section 731 of the Act. Commerce calculated export and constructed 
export prices in accordance with sections 772(a) and (b) of the Act, 
respectively. Normal value is calculated in accordance with section 773 
of the Act. Furthermore, pursuant to section 776(a) and (b) of the Act, 
Commerce has preliminarily relied upon facts otherwise available, with 
adverse inferences, to assign an estimated weighted-average dumping 
margin to Kukdo Chemicals Co. Ltd.\8\ For a full description of the 
methodology underlying the preliminary determination, see the 
Preliminary Decision Memorandum.

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

Preliminary Affirmative Determination Critical Circumstances, in Part

    On August 18, 2025, the petitioner \9\ timely filed a critical 
circumstances allegation, pursuant to section 733(e)(1) of the Act and 
19 CFR 351.206(c)(1), alleging that critical circumstances exist with 
respect to imports of the subject merchandise from Korea.\10\
---------------------------------------------------------------------------

    \9\ The petitioner is Arkema Inc.
    \10\ See Petitioner's Letter, ``Allegation of Critical 
Circumstances,'' dated August 18, 2025.
---------------------------------------------------------------------------

    Section 733(e)(1) of the Act provides that Commerce will 
preliminarily determine that critical circumstances exist in an LTFV 
investigation if there is a reasonable basis to believe or suspect 
that: (A) there is a history of dumping and material injury by reason 
of dumped imports in the United States or elsewhere of the subject 
merchandise, or the person by whom, or for whose account, the 
merchandise was imported knew or should have known that the exporter 
was selling the subject merchandise at less than its fair value and 
that there was likely to be material injury by reason of such sales; 
and (B) there have been massive imports of the subject merchandise over 
a relatively short period. We preliminarily find that critical 
circumstances exist for imports of subject merchandise produced and/or 
exported by Green Chemical Co., Ltd. (Green Chemical). Because we 
preliminarily applied the adverse-facts-available (AFA) rate to the 
company that did not respond to our quantity and value questionnaire 
(i.e., the non-responsive company),\11\ as AFA, we preliminarily find 
that critical circumstances exist for Kukdo Chemicals as well. In 
addition, we preliminarily find that critical circumstances do not 
exist for imports of subject merchandise produced and/or exported by 
Miwon Specialty Chemical Co., Ltd. (Miwon) and all other producers and/
or exporters. For a full discussion of our preliminary critical 
circumstances determination, see the ``Preliminary Critical 
Circumstances'' section of the Preliminary Decision Memorandum.
---------------------------------------------------------------------------

    \11\ The company that decided not to participate in this 
investigation and, therefore, did not respond to Commerce's Q&V 
questionnaire is Kukdo Chemicals Co. Ltd (Kukdo Chemicals).
---------------------------------------------------------------------------

All-Others Rate

    Section 733(d)(1)(A)(ii) and 735(c)(5)(A) of the Act provides 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 calculated estimated weighted-
average dumping margins for Green Chemical and Miwon that are not zero, 
de minimis, or based entirely on facts otherwise available. Commerce 
calculated the all-others rate using a weighted average of the 
estimated weighted-average dumping margins calculated for the examined 
respondents using each company's publicly-ranged values for the 
merchandise under consideration.\12\
---------------------------------------------------------------------------

    \12\ With two respondents under examination, Commerce normally 
calculates: (A) a weighted-average of the estimated weighted-average 
dumping margins calculated for the examined respondents; (B) a 
simple average of the estimated weighted-average dumping margins 
calculated for the examined respondents; and (C) a weighted-average 
of the estimated weighted-average dumping margins calculated for the 
examined respondents using each company's publicly-ranged U.S. sales 
values for the merchandise under consideration. Commerce then 
compares (B) and (C) to (A) and selects the rate closest to (A) as 
the most appropriate rate for all other producers and exporters. 
See, e.g., Ball Bearings and Parts Thereof from France, Germany, 
Italy, Japan, and the United Kingdom: Final Results of Antidumping 
Duty Administrative Reviews, Final Results of Changed-Circumstances 
Review, and Revocation of an Order in Part, 75 FR 53661, 53662 
(September 1, 2010), and accompanying Issues and Decision Memorandum 
at Comment 1. For a complete analysis of the data, see Memorandum, 
``All-Others Rate Calculation,'' dated concurrently with this 
notice.
---------------------------------------------------------------------------

Preliminary Determination

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

------------------------------------------------------------------------
                                                               Weighted-
                                                                average
                      Exporter/producer                         dumping
                                                                margin
                                                               (percent)
------------------------------------------------------------------------
Green Chemical Co., Ltd.; Green Life Science \13\...........       65.72
Miwon Specialty Chemical Co., Ltd...........................       10.94
Kukdo Chemicals Co. Ltd.....................................    * 188.01
All Others..................................................       15.59
------------------------------------------------------------------------
* Rate is based on facts available with adverse inferences.

Suspension of Liquidation and Cash Deposit Requirements
---------------------------------------------------------------------------

    \13\ We preliminarily collapsed Green Chemical Co., Ltd. and 
Green Life Science. See Preliminary Decision Memorandum.
---------------------------------------------------------------------------

    Section 733(e)(2) of the Act provides that, given an affirmative 
determination of critical circumstances, any suspension of liquidation 
shall apply to unliquidated entries of subject merchandise entered, or 
withdrawn from warehouse, for consumption on or after the later of: (a) 
the date which is 90 days before the date on which the suspension of 
liquidation was first ordered; or (b) the date on which notice of 
initiation of the investigation was published. Commerce preliminarily 
finds that critical circumstances exist for imports of subject 
merchandise produced or exported by Green Chemical and Kukdo Chemicals. 
In accordance with section 733(e)(2)(A) of the Act, the suspension of 
liquidation shall apply to unliquidated entries of shipments of subject 
merchandise from Green Chemical and Kukdo Chemicals that were entered, 
or withdrawn from warehouse, for consumption on or after the date which 
is 90 days before the publication of this notice.
    In accordance with section 733(d)(2) of the Act, with regard to 
Miwon and all other exporters and/or producers of subject merchandise, 
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

[[Page 246]]

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; and (3) the 
cash deposit rate for all other producers and exporters will be equal 
to the all-others estimated weighted-average dumping margin.
    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 the Federal Register, 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.

Assistant Secretary for Enforcement and Compliance no later than seven 
days after the date on which the last verification report is issued in 
this investigation. Rebuttal briefs, limited to issues raised in case 
briefs, may be submitted no later than five days after the deadline 
date for case briefs.\14\ Note that Commerce has amended certain of its 
requirements pertaining to the service of documents in 19 CFR 
351.303(f).\15\ Pursuant to 19 CFR 351.309(c)(2) and (d)(2), parties 
who submit case briefs or rebuttal briefs in this investigation are 
encouraged to submit with each argument: (1) a statement of the issue; 
(2) a brief summary of the argument; and (3) a table of authorities.

Commerce would normally address in a comment of the Issues and 
Decision Memorandum.
    \17\ See APO and Service Final Rule.
---------------------------------------------------------------------------

    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 in the Federal Register. 
Requests should contain the party's name, address, and telephone 
number, the number of participants, whether any participant is a 
foreign national, and 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 November 24, 2025, pursuant to 19 CFR 351.210(b)(2)(ii), Miwon 
requested that Commerce postpone the final determination and that 
provisional measures be extended to a period not to exceed six months; 
\18\ on December 4, 2025, Green Chemical also requested that Commerce 
postpone the final determination and extend the application of 
provisional measures by a corresponding period of extension.\19\ On 
November, 21, 2025, the petitioner requested that Commerce postpone the 
final determination in the event of a negative preliminary 
determination.\20\ 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.

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

U.S. International Trade Commission Notification

    In accordance with section 733(f) of the Act, Commerce will notify 
the U.S. International Trade Commission (ITC) of its preliminary 
determination. 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 imports of monomers and oligomers from Korea 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).

Appendix I

Scope of the Investigation

    The products subject to these investigations are certain 
multifunctional acrylate and methacrylate monomers, and acrylated 
bisphenol-A epoxy based oligomers (collectively, certain monomers 
and oligomers or CMOs) that are derived from chemical reactions 
involving the use of acrylic or methacrylic acid. Products within 
the scope are listed below and have the following Chemical Abstracts 
Service (CAS) numbers:

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

                             copolymer acrylate
                             (EPOXY ACRYLATE).
------------------------------------------------------------------------

    The monomers are generally known as multifunctional acrylates 
(MFAs) or multifunctional methacrylates (MFMAs) depending on whether 
the functional groups are acrylate or methacrylate. The monomers 
generally contain stabilizers/inhibitors, which include but are not 
limited to Hydroquinone, Methyl Hydroquinone, and Butylated Hydroxy 
Toluene. The monomers are either difunctional or trifunctional 
(having 2 or 3 functional groups/molecule), have viscosities of 9 to 
15 centipoise (cPs) at 25 degrees Celsius (if difunctional) or 44 to 
110 cPs at 25 degrees Celsius (if trifunctional), have 
(meth)acrylate equivalent weights (molecular weight per number of 
functional groups) between 99 and 158 and molecular weights between 
226 and 472 grams per mol.
    The acrylated bisphenol-A epoxy based oligomer is commonly 
referred to as epoxy acrylate or acrylated epoxy. In contrast to 
epoxy resin, the main characteristic of the epoxy acrylate oligomer 
is that it contains acrylate functional groups which make them 
curable by free-radical polymerization. The epoxy acrylate has a 
molecular weight between 508 to 536 grams per mol and a viscosity of 
2400 to 3600 cPs at 65 degrees Celsius. The epoxy acrylate generally 
contains stabilizers/inhibitors, which include but are not limited 
to Hydroquinone, Methyl Hydroquinone, and Butylated Hydroxy Toluene.
    Certain monomers and oligomers are subject to the scope even if 
an in-scope monomer or oligomer is blended or mixed with one or more 
other in-scope monomers or oligomers.
    Certain monomers and oligomers in any blend or mixture are also 
subject to the scope, so long as the blend or mixture contains no 
less than 20 percent by weight of in-scope CMOs.
    The scope includes merchandise matching the above description 
that has been processed in a third country, including by 
commingling, diluting, introducing, or removing ingredients, or 
performing any other processing that would not otherwise remove the 
merchandise from the scope of the investigations if performed in the 
subject country.
    The scope also includes CMOs that are commingled, mixed or 
blended with in-scope product from sources not subject to these 
investigations.
    Only the subject component(s) of such blends, mixtures or 
commingled products described above is covered by the scope of these 
investigations. Subject merchandise contained in a blended, mixed or 
commingled product described above will not have undergone a 
chemical reaction as a result of being blended, mixed or commingled.
    Notwithstanding the above, specifically excluded from the scope 
are downstream products, including but not limited to, inks, 
coatings and overprint varnishes. For purposes of this exclusion, 
the downstream product requires only the application of energy to be 
cured, e.g., inks or varnish applied to packaging, coatings applied 
to wood flooring, etc. The energy source required to cure the 
downstream product to its substrate can be thermal, ultraviolet 
radiation, visible light, electron beam radiation, or infrared 
radiation.
    This merchandise is currently classifiable under Harmonized 
Tariff Schedule of the United States (HTSUS) subheadings 
2916.12.5050, 2916.14.2050, 3824.99.2900, 3907.29.0000 and 
3907.30.0000. Subject merchandise may also be entered under 
subheadings 2916.12.1000 and 3824.99.9397. The HTSUS subheadings and 
CAS registry numbers are provided for convenience and customs 
purposes only; the written description of the scope is dispositive.
