L-Lysine from China Final Phase Countervailing Duty Investigation
Summary
The U.S. International Trade Commission has scheduled the final phase of antidumping and countervailing duty investigations (Nos. 701-TA-767 and 731-TA-1750) on animal feed-grade L-lysine from China. Commerce previously preliminarily determined the imports are subsidized and sold at less-than-fair-value. The final phase will determine whether the domestic industry is materially injured or threatened with material injury by these imports.
What changed
The ITC is scheduling the final phase of countervailing duty investigation 701-TA-767 and antidumping duty investigation 731-TA-1750 regarding animal feed-grade L-lysine from China (HS 2922.41.00). The scope covers lysine in all forms including lysine monohydrochloride (CAS 657-27-2), lysine sulfate (CAS 60343-69-3), and liquid lysine (CAS 56-87-1), whether pure or combined with other products. Commerce has already made preliminary affirmative determinations that the imports are subsidized and sold at less-than-fair-value.
U.S. producers of animal feed-grade lysine and importers of Chinese lysine merchandise should prepare for the final phase of these investigations. Domestic interested parties should prepare testimony for the final hearing. The investigation will determine whether countervailing and antidumping duties should be imposed. Any final affirmative determination by the ITC, combined with Commerce's final determination, could result in significant duties on Chinese lysine imports, affecting supply chains and pricing in the animal feed industry.
What to do next
- U.S. producers of animal feed-grade lysine should prepare testimony and evidence for the final phase hearing
- Importers of Chinese L-lysine should monitor ITC proceedings and assess potential duty liability
- Parties with interest in the domestic lysine industry should file appearance notices with the ITC

SUMMARY:
The Commission hereby gives notice of the scheduling of the final phase of antidumping and countervailing duty investigation
Nos. 701-TA-767 and 731-TA-1750 (Final) pursuant to the Tariff Act of 1930 to determine whether an industry in the United
States is materially injured or threatened with material injury, or the establishment of an industry in the United States
is materially retarded, by reason of imports of animal feed-grade l-lysine from China, provided for in subheading 2922.41.00
of the Harmonized Tariff Schedule of the United States, preliminarily determined by the Department of Commerce (“Commerce”)
to be subsidized and sold at less-than-fair-value.

SUPPLEMENTARY INFORMATION:
Scope. —For purposes of these investigations, Commerce has defined the subject merchandise as “. . . animal feed grade L-lysine (lysine).
Lysine is an essential amino acid added to animal feed that is used in the biosynthesis of proteins. The scope covers lysine
regardless of form, including lysine monohydrochloride, also referred to as lysine HCL, lysine sulfate, and liquid lysine.
The scope includes lysine that has been coated or encapsulated for use with ruminants to ensure bioavailability.
Lysine HCL in the dry form has the molecular formula C 6 H 14 N 2 O 2 HCl. The Chemical Abstracts Service (CAS) registry number for lysine HCL is 657-27-2. Lysine HCL contains a minimum of 78
percent lysine by weight, as well as additional amino acids, carbohydrates, mineral salts, and organic acids. Lysine sulfate
is the sulfate salt of lysine, and in the dry form it has the molecular formula C 6 H 16 N 2 O 6 S. The CAS registry number for lysine sulfate is 60343-69-3. Lysine sulfate typically contains approximately 40-70 percent
lysine by weight, as well as additional amino acids, carbohydrates, mineral salts, and organic acids. Liquid lysine is a concentrated
form of lysine in an aqueous solution with the molecular formula C 6 H 14 N 2 O 2. The CAS registry number for liquid lysine is 56-87-1. Liquid lysine normally contains at least 50 percent lysine by weight,
as well as additional amino acids, carbohydrates, mineral salts, and organic acids.
The scope includes animal feed grade lysine that is combined with other products, including for example, by mixing, blending,
compounding, or granulating (e.g., base mixes, premixes, and concentrates). For such combined products, only the lysine component is covered by the scope of
this investigation.
Subject merchandise also includes lysine that has been processed in a third country, including by commingling, diluting, adding
or removing additives, refining, converting from liquid to dry or dry to liquid form, coating or encapsulating, or performing
any processing that would not otherwise remove the merchandise from the scope of the investigation if performed in the subject
country . . .”
Background. —The final phase of these investigations is being scheduled pursuant to sections 705(b) and 731(b) of the Tariff Act of 1930
(19 U.S.C. 1671d(b) and 1673d(b)), as a result of affirmative preliminary determinations by Commerce that certain benefits
which constitute subsidies within the meaning of § 703 of the Act (19 U.S.C. 1671b) are being provided to manufacturers, producers,
or exporters in China of animal feed-grade l-lysine, and that such products are being sold in the United States at less than
fair value within the meaning of § 733 of the Act (19 U.S.C. 1673b). The investigations were requested in petitions filed
on May 28, 2025, by Archer Daniels Midland Company, Chicago, IL (“ADM”), CJ Bio America, Inc. an Iowa corporation (“CJ America”),
and Evonik Corporation, Piscataway, NJ (“Evonik”).
For further information concerning the conduct of this phase of the investigations, hearing procedures, and rules of general
application, consult the Commission's Rules of Practice and Procedure, part 201, subparts A and B (19 CFR part 201), and part
207, subparts A and C (19 CFR part 207).
Participation in the investigations and public service list. —Persons, including industrial users of the subject merchandise and, if the merchandise is sold at the retail level, representative
consumer organizations, wishing to
participate in the final phase of these investigations as parties must file an entry of appearance with the Secretary to the
Commission, as provided in § 201.11 of the Commission's rules, no later than 21 days prior to the hearing date specified in
this notice. A party that filed a notice of appearance during the preliminary phase of the investigations need not file an
additional notice of appearance during this final phase. The Secretary will maintain a public service list containing the
names and addresses of all persons, or their representatives, who are parties to the investigations.
Please note the Secretary's Office will accept only electronic filings during this time. Filings must be made through the
Commission's Electronic Document Information System (EDIS, https://edis.usitc.gov). No in-person paper-based filings or paper copies of any electronic filings will be accepted until further notice.
Limited disclosure of business proprietary information (BPI) under an administrative protective order (APO) and BPI service
list. —Pursuant to § 207.7(a) of the Commission's rules, the Secretary will make BPI gathered in the final phase of these investigations
available to authorized applicants under the APO issued in the investigations, provided that the application is made no later
than 21 days prior to the hearing date specified in this notice. Authorized applicants must represent interested parties,
as defined by 19 U.S.C. 1677(9), who are parties to the investigations. A party granted access to BPI in the preliminary phase
of the investigations need not reapply for such access. A separate service list will be maintained by the Secretary for those
parties authorized to receive BPI under the APO.
Staff report. —The prehearing staff report in the final phase of these investigations will be placed in the nonpublic record on June 30,
2026, and a public version will be issued thereafter, pursuant to § 207.22 of the Commission's rules.
