U.S. Department of Commerce Final Decision on L-Lysine Import from China
Estimated reading time: 3–5 minutes
The U.S. Department of Commerce has made a final decision. It will place a countervailing duty on L-lysine from China. This means extra charges will be added to the cost of L-lysine coming from China.
What is L-Lysine?
L-lysine is a type of amino acid. Animals need it to help them grow. It helps in making proteins. Farmers add L-lysine to animal feed for pigs, chickens, and cows. It’s important for animal health.
Period of Investigation
The Department of Commerce checked how L-lysine was sent from China. They looked at data from January 1, 2024, to December 31, 2024. They wanted to see if producers in China had unfair help from their government. The investigation started on January 22, 2026.
The Findings
The investigation found that Chinese producers received unfair help, called subsidies, from their government. This helps them sell products cheaper in the United States. This hurts American producers.
Companies Involved
Researchers examined several companies, like Inner Mongolia Eppen Biotech Co. Ltd, and found some were given unfair advantages. Three Chinese companies have to face these duties. They are Helionjiang Wanli Runda Biotechnology Co., Ltd., Shouguang Golden-land Industry & Trading Co Ltd, and Inner Mongolia Eppen Biotech Co. Ltd.
Rates Announced
- Inner Mongolia Eppen Biotech Co. Ltd will have a countervailing duty of 48.21%.
- Helionjiang Wanli Runda Biotechnology Co., Ltd. and Shouguang Golden-land Industry & Trading Co Ltd will both face a duty rate of 82.11%. This rate is harsher because they didn’t provide the necessary information.
All other producers will have the same rate as Inner Mongolia Eppen, which is 48.21%.
What’s Next?
The U.S. International Trade Commission will look at this decision. They will decide if U.S. businesses are being hurt. They have 45 days to make this decision. If they agree, the duties will stay. If they disagree, the duties will be removed.
Final Steps
All companies involved must respect the new rules. They should also make sure any private information shared with the U.S. Department of Commerce is kept safe.
This decision is important for trade between the United States and China. It ensures a fair marketplace for goods like L-lysine. The U.S. continues to watch out for its businesses and workers.
