Lysine Lowball? US Probes China's Unfair Amino Acid Pricing
Published Date: 3/6/2026
Notice
Summary
The U.S. Department of Commerce found that L-lysine from China is likely being sold in the U.S. for less than fair value, which could mean unfair pricing. This affects Chinese exporters and U.S. buyers, and the government is extending the investigation and provisional measures to make sure everything’s fair. Final decisions are postponed, so expect updates and possible money impacts soon!
Analyzed Economic Effects
3 provisions identified: 0 benefits, 3 costs, 0 mixed.
Immediate Cash Deposits Required
If you import L-lysine into the U.S., U.S. Customs and Border Protection will suspend liquidation and require cash deposits for entries entered or withdrawn from warehouse for consumption on or after March 6, 2026. The required deposit will equal the estimated dumping margin assigned to the producer/exporter (examples in the notice include 72.18%, 41.22%, and 64.54%).
China-Wide Rate for Non-Separate Entities
For any China producers or exporters that did not get a separate rate, Commerce will apply the China-wide estimated dumping margin of 142.59% for cash deposits. That 142.59% rate is based on facts available with adverse inferences.
Provisional Measures Extended; Final Delayed
Commerce extended provisional measures from the standard four-month period to a period not greater than six months and postponed the final determination so it will be made no later than 135 days after the publication of this preliminary determination. The requester letters for postponement were dated February 25 and 26, 2026, and the preliminary determination was published March 6, 2026.
