SUPPLEMENTARY INFORMATION:
Background
On September 16, 2025, Commerce published in the Federal Register
its preliminary affirmative determination in the LTFV investigation of
MDI from China, in which it also postponed the final determination
until January 29, 2026.\1\ We invited interested parties to comment on
the Preliminary Determination.\2\
---------------------------------------------------------------------------
\1\ See Methylene Diphenyl Diisocyanate from the People's
Republic of China: Preliminary Affirmative Determination of Sales at
Less-Than-Fair-Value, Postponement of Final Determination, and
Extension of Provisional Measures, 90 FR 44629 (September 16, 2025),
and accompanying Preliminary Decision Memorandum.
\2\ Id.
---------------------------------------------------------------------------
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 final
determination is now April 7, 2026.
---------------------------------------------------------------------------
\3\ See Memorandum, ``Deadlines Affected by the Shutdown of the
Federal Government,'' dated November 14, 2025.
\4\ See Memorandum, ``Tolling of all Case Deadlines,'' dated
November 24, 2025.

\5\ See Memorandum, ``Issues and Decision Memorandum for the
Final Affirmative Determination in the Less-Than-Fair-Value
Investigation of Methylene Diphenyl Diisocyanate from the People's
Republic of China,'' dated concurrently with, and hereby adopted by,
this notice (Issues and Decision Memorandum).
---------------------------------------------------------------------------
Scope of the Investigation
The product subject to this investigation is MDI from China. For a
complete description of the scope of this investigation, see Appendix
I.
Scope Comments
In the Preliminary Scope Memorandum, we set aside a period of time
for parties to raise issues regarding product coverage (i.e., scope) in
scope-specific case briefs or other written comments. No interested
party submitted scope comments; therefore, we have made no
modifications to the scope language as it appeared in the Initiation
Notice. See Appendix I.
Verification
The mandatory respondent in this investigation is not eligible for
a separate rate and is therefore part of the China-wide entity. Because
Commerce has found the China-wide entity to be uncooperative, Commerce
did not conduct verification.
Analysis of Comments Received
All issues raised in the case and rebuttal briefs submitted by
interested parties in this investigation are addressed in the Issues
and Decision Memorandum. A list of the issues addressed in the Issues
and Decision Memorandum is attached to this notice at Appendix II.
Changes Since the Preliminary Determination
Since the Preliminary Determination, we have made certain changes
to the estimated weighted-average dumping margin for the China-wide
entity and the estimated weighted-average dumping margin for non-
examined companies that are eligible for a separate rate. For a
discussion of these changes, see the Issues and Decision Memorandum.
China-Wide Entity and Use of Adverse Facts Available (AFA)
Consistent with the Preliminary Determination,\6\ Commerce
continues to find that, pursuant to sections 776(a) and (b) of the
Tariff Act of 1930, as amended (the Act), the use of facts otherwise
available, with adverse inferences, is warranted in determining the
estimated weighted-average dumping margin for the China-wide entity.\7\
For this final determination, there is no new information on the record
that would cause us to reconsider our preliminary decision to apply AFA
to the China-wide entity. Further, we calculated a new dumping margin
based on the lowest U.S. price, factors of production (FOPs)
information and certain surrogate values (SVs) from the Petition, and
other SVs submitted to the record in this investigation.\8 \Therefore,
as AFA, we assigned the estimated weighted-average dumping margin of
159.04 percent to the China-wide entity.\9\

Final Determination,'' dated April 7, 2026; see also Issues and
Decision Memorandum at Comment 5.
\9\ See Issues and Decision Memorandum at Comment 5.
---------------------------------------------------------------------------
Separate Rate
We preliminarily granted a separate rate to certain companies that
we did not select for individual examination. No party commented on
Commerce's preliminary decision to grant a separate rate to Covestro
Polymers (China) Co., Ltd. or Shandong Mingko Co., Ltd.; therefore, we
continue to find that these two companies are eligible for a separate
rate. Additionally, we preliminarily determined that the mandatory
respondent, Wanhua,\10\ is not eligible for a separate rate. Wanhua
commented on Commerce's preliminary decision not to grant it a separate
rate.\11\ We have addressed this comment in the Issues and Decision
Memorandum. We have made no changes to Commerce's preliminary separate
rate eligibility determinations for the non-selected
[[Page 18822]]
separate rate companies for this final determination.
---------------------------------------------------------------------------
\10\ Commerce determined that Wanhua Chemical (Singapore) Pte.
Ltd. (Wanhua Singapore), Wanhua Chemical (Ningbo) Trading Co., Ltd.
(Wanhua Ningbo), Wanhua Chemical (Fujian) Co., Ltd. (Wanhua Fujian),
Wanhua Chemical (Fujian) Isocyanate Co., Ltd., (Wanhua Isocyanate),
Wanhua Chemical (Guangdong) Co., Ltd. (Wanhua Guangdong), and Wanhua
Chemical (Yantai) Trading Co., Ltd. (Wanhua Yantai), Wanhua Chemical
Group Co., Ltd. (Wanhua Group), and Wanhua Chemical (Ningbo) Co.,
Ltd. (Ningbo Company){time} should be collapsed and treated as a
single entity (Wanhua). See Memorandum, ``Preliminary Determination
of Affiliation and Single Entity Determination for Wanhua Chemical
(Singapore) Pte. Ltd., and Wanhua Chemical (Ningbo) Trading Co.,
Ltd.,'' dated August 19, 2025; and Preliminary Determination PDM at
4-5. We received no comments on this preliminary determination;
thus, we continue to treat Wanhua Chemical (Singapore) Pte. Ltd.
(Wanhua Singapore), Wanhua Chemical (Ningbo) Trading Co., Ltd.
(Wanhua Ningbo), Wanhua Chemical (Fujian) Co., Ltd. (Wanhua Fujian),
Wanhua Chemical (Fujian) Isocyanate Co., Ltd., (Wanhua Isocyanate),
Wanhua Chemical (Guangdong) Co., Ltd. (Wanhua Guangdong), and Wanhua
Chemical (Yantai) Trading Co., Ltd. (Wanhua Yantai), Wanhua Chemical
Group Co., Ltd. (Wanhua Group), and Wanhua Chemical (Ningbo) Co.,
Ltd. (Ningbo Company)) as a single entity (Wanhua) for purposes of
this final determination.
\11\ See Preliminary Determination at ``Separate Rates''
section.
---------------------------------------------------------------------------
As the basis for the estimated weighted-average dumping margin for
the non-examined producer/exporter combinations eligible for a separate
rate in this final determination, we calculated new dumping margins
based on all of the U.S. prices, FOPs and certain SVs included in the
Petition along with other SVs submitted to the record of this
investigation.\12\
---------------------------------------------------------------------------
\12\ See Memorandum, ``China-Wide Rate and Separate Rate for
Final Determination,'' dated April 7, 2026.
---------------------------------------------------------------------------
Combination Rates
Consistent with the Preliminary Determination, Commerce determined
combination rates for the companies eligible for a separate rate.
Final Determination
Commerce determines that the following estimated weighted-average
dumping margins exist for the period July 1, 2024, through December 31,
2024:

------------------------------------------------------------------------
* This rate is based on facts available with adverse inferences.
Disclosure
Commerce intends to disclose the calculations performed in
connection with this final determination to interested parties within
five days after public announcement of the final determination or, if
there is no public announcement, within five days of the date of
publication of the notice of final determination in the Federal
Register, in accordance with 19 CFR 351.224(b).
Suspension of Liquidation
In accordance with section 733(d)(2) of the Act, we instructed U.S.
Customs and Border Protection (CBP) to suspend liquidation of entries
of subject merchandise, as described in Appendix I of this notice, that
were entered, or withdrawn from warehouse, for consumption on or after
September 16, 2025, the date of publication of the Preliminary
Determination in the Federal Register. In accordance with section
733(d) of the Act, we subsequently instructed CBP to discontinue the
suspension of liquidation of all entries of subject merchandise entered
or withdrawn from warehouse, on or after March 16, 2026, but to
continue the suspension of liquidation of all entries of subject
merchandise on or before March 15, 2025.
If the U.S. International Trade Commission (ITC) issues a final
affirmative injury determination, the we will issue an antidumping duty
(AD) order, reinstate the suspension of liquidation, and require a cash
deposit for estimated antidumping duties, in accordance with section
736(a) of the Act, effective on the publication date of the ITC's final
affirmative determination in the Federal Register. The cash deposit
required will be, as follows: (1) for the exporter and producer
combinations listed in the table above, the cash deposit rate will be
the rate identified in this final determination; (2) for all
combinations of Chinese exporters and producers of subject merchandise,
the cash deposit rate will be the cash deposit rate established for the
China-wide entity; and (3) for all non-Chinese exporters of subject
merchandise that have not received their own separate rate above, the
cash deposit rate will be the cash deposit rate applicable to the
Chinese exporter/producer combination that supplied that non-Chinese
exporter.
If the ITC determines that material injury, or threat of material
injury, does not exist, this proceeding will be terminated, and all
cash deposits for estimated antidumping duties will be refunded and the
suspension of liquidation will be lifted.
ITC Notification
In accordance with section 735(d) of the Act, Commerce will notify
the ITC of its final affirmative determination of sales at LTFV.
Because Commerce's final determination is affirmative, in accordance
with section 735(b)(2) of the Act, the ITC will make its final
determination as to whether the domestic industry in the United States
is materially injured, or threatened with material injury, by reason of
imports, or sales (or the likelihood of sales) for importation, of MDI
no later than 45 days after this final determination. If the ITC
determines that material injury or threat of material injury does not
exist, this proceeding will be terminated, all cash deposits will be
refunded or canceled, and suspension of liquidation will be lifted. If
the ITC determines that such injury does exist, Commerce will issue an
AD order directing CBP to assess, upon further instructions by
Commerce, antidumping duties on all imports of the subject merchandise
that are entered, or withdrawn from warehouse, for consumption on or
after the effective date of the suspension of liquidation, as discussed
above in the ``Suspension of Liquidation'' section above.
Administrative Protective Order (APO)
This notice serves as the only reminder to parties subject to an
APO of their responsibility concerning the disposition of proprietary
information disclosed under APO in accordance with 19 CFR
351.305(a)(3). Timely written notification of the return or destruction
of APO materials or conversion to judicial protective order is hereby
requested. Failure to comply with the regulations and terms of an APO
is a sanctionable violation.
Notification to Interested Parties
This final determination is issued and published in accordance with
sections 735(d) and 777(i) of the Act, and 19 CFR 351.210(c).

Appendix I
Scope of the Investigation
The merchandise subject to this investigation is methylene
diphenyl diisocyanate (MDI), which is an aromatic polyisocyanate
material whose composition includes two or more isocyanate groups
(i.e., functional group containing a nitrogen atom, a carbon atom,
and an oxygen atom bonded together (-NCO)) attached to one or more
benzene rings (i.e., flat, symmetrical molecule made up of six
carbon atoms arranged in a hexagonal ring and has the chemical
formula C<INF>6</INF>H<INF>6</INF>) that are joined by methylene
bridges (i.e., a carbon atom bound to two hydrogen atoms (-
CH<INF>2</INF>-) and connected by single bonds to two other distinct
atoms in the rest of the molecule). MDI is commonly called
Polymeric, Monomeric, or Modified MDI and may also be referred to
under other names, including Methylene bisphenyl isocyanate, 4,4'-
Diphenylmethane diisocyanate, Methylene di-p-phenylene ester of
isocyanic acid, Methylene bis(4-phenyl isocyanate), and
polymethylene polyphenylene isocyanate. MDI is normally associated
with Chemical Abstracts Service (CAS) registry numbers 9016-87-9,
101-68-8, 5873-54-1, 2536-05-2, 1689576-89-3, 25686-28-6, 26447-40-
5, and 39310-05-9, but several others are also used.
MDI ranges in physical form from low viscosity liquids to
solids. MDI is covered by the scope of this investigation
irrespective of whether it has gone through a distillation process
and regardless of acid content, reactivity, functionality, freeze
stability, physical form, viscosity, grade, purity, molecular
weight, or packaging.
MDI may contain additives, such as catalysts, solvents,
plasticizers, antioxidants, fire retardants, colorants, pigments,
diluents, thickeners, fillers, softeners, toughening agents. The
scope does not include mixtures of MDI with other materials, when
the combined MDI component comprises less than 40 percent of the
total weight of the mixture.
MDI may be partially reacted with itself, polyol, or polyamines,
and retain MDI component that has not fully chemically reacted so as
to convert it into a different product no longer containing
isocyanate groups. These products are known as homopolymer,
uretonimine MDI, carbodiimide MDI, or prepolymers. The scope does
not include partially reacted MDI when its NCO content is less than
10 weight percentage.
For MDI that enter as part of a system with separately packaged
resin consisting mostly of a chemical compound that has an OH
reactive group, including polyol, only the MDI portion of the system
is included in the scope. The scope does not include any separately
packaged polyol that would not fall within the scope if entered on
its own.
The scope includes merchandise matching the above description
that has been processed in a third country, including by
commingling, diluting, introducing or removing 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 MDI that is commingled or blended with
MDI from sources not subject to this investigation. Only the subject
component of such commingled products is covered by the scope of
this investigation.
This merchandise is currently classifiable under Harmonized
Tariff Schedule of the United States (HTSUS) subheadings
2929.10.8010 and 3909.31.0000. Subject merchandise may also be
entered under subheadings 3824.99.2600, 3909.50.1000, 3909.50.2000,
3909.50.5000, 3824.99.2900, 3506.91.5000, 3911.90.4500,
3921.13.5000, and 3920.99.5000. The HTSUS subheadings are provided
for convenience and customs purposes only; the written description
of the scope is dispositive.
