L-Lysine From the People's Republic of China: Final Affirmative Determination of Sales at Less Than Fair Value

Published Jul 23, 2026Source: Federal RegisterView original

Summary

This antidumping determination targets L-lysine, an amino acid used primarily as an animal feed additive and dietary supplement, not a research peptide. While lysine is a building block for peptide synthesis, this trade action affects bulk commodity imports from China and may indirectly raise raw material costs for some suppliers, but has no direct regulatory impact on peptide research products.

AI Analysis

Key Changes

•Commerce determined L-lysine from China is being sold in the U.S. at less than fair value (LTFV)

•Potential imposition of antidumping duties on Chinese L-lysine imports

Affected Compound

L-lysine

Action Required

Vendors sourcing bulk L-lysine or lysine-derived raw materials from China should anticipate potential price increases due to antidumping duties and consider alternative supply sources. No action required for peptide research operations not reliant on Chinese lysine.

Effective Date
