US Targets China's L-Lysine: Will Animal Feed Get Pricier?

Published Date: 4/3/2026

Notice

Summary

The U.S. is taking a close look at animal feed-grade L-lysine imported from China to see if it’s hurting American businesses by being unfairly cheap or subsidized. This investigation could lead to extra taxes on these imports to protect U.S. producers. The final decision is moving forward after a preliminary finding, with important deadlines starting March 6, 2026.

Analyzed Economic Effects

2 provisions identified: 0 benefits, 1 costs, 1 mixed.

Possible Duties on L‑lysine Imports

The U.S. has begun final antidumping and countervailing duty investigations into animal feed‑grade L‑lysine from China and Commerce preliminarily found the product subsidized and sold at less‑than‑fair‑value. This investigation could lead to extra taxes (countervailing or antidumping duties) on those imports to protect U.S. producers; the final phase was scheduled beginning March 6, 2026.

Scope Covers Third‑Country Processing

The investigation explicitly covers animal feed‑grade L‑lysine in all forms (including lysine HCL, lysine sulfate, and liquid lysine) and also covers lysine that has been processed in a third country. That means imports that were commingled, diluted, coated, converted between liquid and dry, or otherwise processed in another country remain within the investigation's scope.
