SUPPLEMENTARY INFORMATION:

Background

In accordance with section 735(d) and 777(i) of the Tariff Act of
1930, as amended (the Act), on May 27, 2026, Commerce published its
affirmative final determination of sales at less than fair value (LTFV)
of monomers and oligomers from Korea.\1\ On July 13, 2026, the ITC
notified Commerce of its affirmative final determination, pursuant to
section 735(d) of the Act, that an industry in the United States is
materially injured within the meaning of section 735(b)(1)(A)(i) of the
Act by reason of LTFV imports of monomers and oligomers from Korea.\2\

\1\ See Certain Monomers and Oligomers from the Republic of
Korea: Final Affirmative Determination of Sales at Less Than Fair
Value and Final Affirmative Determination of Critical Circumstances,
91 FR 31415 (May 27, 2026) (Korea Final Determination), and
accompanying Issues and Decision Memorandum (IDM).
\2\ See ITC's Letter, ``Notification of Final Determination,''
dated July 13, 2026.

Scope of the Order

The products covered by this order are monomers and oligomers from
Korea. For a complete description of the scope of this order, see the
appendix to this notice.

Antidumping Duty Order

On July 13, 2026, in accordance with 735(d) of the Act, the ITC
notified Commerce of its final determination that an industry in the
United States is materially injured within the meaning of section
735(b)(1)(A)(i) of the Act by reason of imports of monomers and
oligomers from Korea that are sold in the United States at LTFV.\3\
Therefore, in accordance with sections 735(c)(2) and 736 of the Act,
Commerce is issuing this AD order. Because the ITC determined that
imports of monomers and oligomers are materially injuring a U.S.
industry, unliquidated entries of such merchandise from Korea, entered
or withdrawn from warehouse for consumption, on or after January 5,
2026, are subject to the assessment of antidumping duties.

\3\ Id.

Therefore, in accordance with section 736(a)(1) of the Act,
Commerce will direct U.S. Customs and Border Protection (CBP) to
assess, upon further instruction by Commerce, antidumping duties equal
to the amount by which the normal value of the merchandise exceeds the
export price (or constructed export price) of the merchandise, for all
relevant entries of monomers and oligomers from Korea. Antidumping
duties will be assessed on unliquidated entries of monomers and
oligomers entered, or withdrawn from warehouse, for consumption on or
after January 5, 2026, the date of the publication of the Preliminary
Determination but will not include entries occurring after the
expiration of the provisional measures period and before the
publication of the ITC's final injury determination under section
735(b) of the Act, as further described in the ``Provisional Measures--
AD'' section of this notice.\4\

\4\ See Certain Monomers and Oligomers from the Republic of
Korea: Preliminary Affirmative Determination of Sales at Less Than
Fair Value, Preliminary Affirmative Determination of Critical
Circumstances, in Part, and Postponement of Final Determination, and
Extension of Provisional Measures, 91 FR 244 (January 5, 2026)
(Preliminary Determination).

Critical Circumstances--AD

In addition, the ITC found that critical circumstances do not exist
with respect to imports of monomers and oligomers from Korea. As a
result, we intend to instruct CBP to lift the suspension of liquidation
and to refund all cash deposits for estimated antidumping duties with
respect to entries of subject merchandise entered, or withdrawn from
warehouse, for consumption on or after October 7, 2025, (i.e., 90 days
prior to the date of publication of the affirmative Preliminary
Determination), but before January 5, 2026 (i.e., the date of
publication of the Preliminary Determination).

Suspension of Liquidation and Cash Deposits

In accordance with section 736 of the Act, Commerce intends to
instruct CBP to reinstitute the suspension of liquidation of monomers
and oligomers from Korea, effective on the date of publication of the
ITC's final affirmative injury determination in the Federal Register.
Commerce also intends to instruct CBP to require cash deposits equal to
the estimated weighted-average dumping margins listed in the Final
Determination. The all-others rate applies to all producers or
exporters not specifically listed. These instructions suspending
liquidation and cash deposit requirements will remain in effect until
further notice.

Estimated Weighted-Average Dumping Margins

The estimated weighted-average dumping margins are as follows:

Weighted-
average
Exporter/producer dumping
margin
(percent)

Green Chemical Co., Ltd.; Green Life Science................ 65.72
Miwon Specialty Chemical Co., Ltd........................... * 155.42
Kukdo Chemicals Co. Ltd..................................... * 155.42
All Others.................................................. 65.72

* Rate based on facts available with adverse inferences.

Provisional Measures

Section 733(d) of the Act states that instructions issued under
section 733(d)(1) and (2) of the Act pursuant to an affirmative
preliminary determination may not remain in effect for more than four
months, except where exporters representing a significant proportion of
exports of the subject merchandise request that Commerce extends the
four-month period to no more than six months. At the request of
exporters that account for a significant proportion of exports of
monomers and oligomers from Korea, Commerce extended the four-month
period to six months in this investigation. Commerce published the
Preliminary Determination on January 5, 2026.\5\

\5\ See Preliminary Determination.

The extended provisional measures period, beginning on the date of
publication of the Preliminary Determination, ended on July 3, 2026.
Therefore, in accordance with section 733(d) of the Act, Commerce
intends to instruct CBP to terminate the suspension of liquidation and
to liquidate, without regard to antidumping duties, unliquidated
entries of monomers and oligomers from Korea entered, or withdrawn from
warehouse, for consumption on or after July 4, 2026, the first day
provisional measures were no longer in effect, until and through the
day preceding the date of publication of the ITC's final injury
determination in the Federal Register. Suspension of liquidation and
the collection of cash deposits will resume on the date of publication
of the ITC's final injury determination in the Federal Register.

Establishment of the Annual Inquiry Service List

On September 20, 2021, Commerce published the final rule titled

``Regulations to Improve Administration and Enforcement of Antidumping
and Countervailing Duty Laws'' in the Federal Register.\6\ On September
27, 2021, Commerce also published the notice titled ``Scope Ruling
Application; Annual Inquiry Service List; and Informational Sessions''
in the Federal Register.\7\ The Final Rule and Procedural Guidance
provide that Commerce will maintain an annual inquiry service list for
each order or suspended investigation, and any interested party
submitting a scope ruling application or request for circumvention
inquiry shall serve a copy of the application or request on the persons
on the annual inquiry service list for that order, as well as any
companion order covering the same merchandise from the same country of
origin.\8\

\6\ See Regulations to Improve Administration and Enforcement of
Antidumping and Countervailing Duty Laws, 86 FR 52300 (September 20,
2021) (Final Rule).
\7\ See Scope Ruling Application; Annual Inquiry Service List;
and Informational Sessions, 86 FR 53205 (September 27, 2021)
(Procedural Guidance).
\8\ Id.

In accordance with the Procedural Guidance, for orders published in
the Federal Register after November 4, 2021, Commerce will create an
annual inquiry service list segment in Commerce's online e-filing and
document management system, Antidumping and Countervailing Duty
Electronic Service System (ACCESS), available at https://access.trade.gov, within five business days of publication of the
order. Each annual inquiry service list will be saved in ACCESS, under
each case number, and under a specific segment type called ``AISL-
Annual Inquiry Service List.'' \9\

\9\ This segment will be combined with the ACCESS Segment
Specific Information (SSI) field, which will display the month in
which the notice of the order or suspended investigation was
published in the Federal Register, also known as the anniversary
month. For example, for an order under case number A-000-000 that
was published in the Federal Register in January, the relevant
segment and SSI combination will appear in ACCESS as ``AISL-January
Anniversary.'' Note that there will be only one annual inquiry
service list segment per case number, and the anniversary month will
be pre-populated in ACCESS.

Interested parties who wish to be added to the annual inquiry
service list for an order must submit an entry of appearance to the
annual inquiry service list segment for the order in ACCESS within 30
days after the date of publication of the order. For ease of
administration, Commerce requests that law firms with more than one
attorney representing interested parties in an order designate a lead
attorney to be included on the annual inquiry service list. Commerce
will finalize the annual inquiry service list within five business days
thereafter. As mentioned in the Procedural Guidance, the new annual
inquiry service list will be in place until the following year, when
the Opportunity Notice for the anniversary month of the order is
published.
Commerce may update an annual inquiry service list at any time as
needed based on interested parties' amendments to their entries of
appearance to remove or otherwise modify their list of members and
representatives, or to update contact information. Any changes or
announcements pertaining to these procedures will be posted to the
ACCESS website at https://access.trade.gov.

Special Instructions for the Petitioner and Foreign Governments

In the Final Rule, Commerce stated that, ``after an initial request
and placement on the annual inquiry service list, both the petitioners
and foreign governments will automatically be placed on the annual
inquiry service list in the years that follow.'' \10\ Accordingly, as
stated above, the petitioner and the Government of Korea should submit
their initial entry of appearance after publication of this notice in
order to appear in the first annual inquiry service list for those
orders for which they qualify as an interested party. Pursuant to 19
CFR 351.225(n)(3), the petitioner and the Government of Korea will not
need to resubmit their entries of appearance each year to continue to
be included on the annual inquiry service list. However, the petitioner
and the Government of Korea are responsible for making amendments to
their entries of appearance during the annual update to the annual
inquiry service list in accordance with the procedures described above.

\10\ See Final Rule, 86 FR at 52335.

Appendix

Scope of the Order

The products subject to this investigation 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:

CAS No. Description Molecular formula

109-16-0.............................. Triethylene glycol dimethacrylate C14H22O6
(TEGDMA).
13048-33-4............................ 1,6-hexanediol diacrylate (HDDA)... C12H18O4
42978-66-5............................ Tripropylene glycol diacrylate C15H24O6
(TPGDA).
3290-92-4............................. Trimethylolpropane trimethacrylate C18H26O6
(TMPTMA).
15625-89-5............................ Trimethylolpropane triacrylate C15H20O6
(TMPTA).
28961-43-5............................ Ethoxylated trimethylol-propane (C2H4O)n(C2H4O)n(C2H4O)nC15H20O6
triacrylate (EOTMPTA).
57472-68-1............................ Dipropylene glycol diacrylate C12H18O5
(DPGDA).
55818-57-0............................ Bisphenol-A-epichlorohydrin (C15H16O2.C3H5ClO)x.xC3H4O2
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.
