Cheap Chinese Lysine Dumping? US Commerce Investigates Fair Play
Published Date: 6/24/2025
Notice
Summary
The U.S. Department of Commerce is starting an investigation to see if L-lysine from China is being sold unfairly cheap in the U.S. This affects American companies like Archer Daniels Midland and Evonik, who want fair prices. If unfair pricing is found, extra duties could be added soon, helping U.S. businesses compete better.
Analyzed Economic Effects
4 provisions identified: 1 benefits, 2 costs, 1 mixed.
Initiation Includes 198.51% Dumping Estimate
Commerce's initiation documents state an estimated dumping margin of 198.51 percent for L‑lysine from China based on the petitioners' data. That 198.51% figure is the estimated dumping margin cited at initiation.
Commerce Opens LTFV Probe on L‑Lysine
On June 17, 2025, the Department of Commerce initiated a less‑than‑fair‑value (LTFV) antidumping investigation of animal‑feed grade L‑lysine imported from the People’s Republic of China. Commerce will make its preliminary LTFV determination no later than 140 days after initiation, and the investigation covers the period October 1, 2024 through March 31, 2025.
Chinese Exporters Must File Questionnaires
Commerce identified 113 Chinese producers/exporters and will issue quantity‑and‑value (Q&V) questionnaires; responses to the Q&V questionnaire must be submitted by 5:00 p.m. ET on July 1, 2025. Exporters and producers that want separate‑rate consideration must submit a separate rate application 21 days after publication of this initiation notice and must fully respond to Commerce's antidumping questionnaires if selected.
ITC and Investigation Timing Rules
The U.S. International Trade Commission (ITC) will preliminarily determine within 45 days after the petition filing whether imports of L‑lysine from China are materially injuring U.S. industry; a negative ITC finding will terminate the investigation. If the ITC indicates injury, Commerce's LTFV investigation will proceed under statutory time limits.
