Anti-dumping tariffs on Chinese lysine: what importers and feed manufacturers must do in 2026

Key data

European importers of Chinese lysine face unprecedented cost uncertainty. The Commission Implementing Regulation (EU) 2026/1824, published on July 29, 2026, activates the mandatory import registration mechanism as a preliminary step to the possible imposition of definitive anti-dumping duties. The key point: any shipment registered from July 28 could be subject to additional tariffs with retroactive effect if the investigation concludes that China is selling lysine below its real cost.

Lysine is an essential amino acid that cannot be synthesized sufficiently by animals and is added massively to feed for poultry, pigs and other farm animals. Its price and availability have a direct impact on production costs throughout the European livestock and agri-food chain.

What does this regulation establish?

Regulation 2026/1824 does not yet impose definitive tariffs. It establishes a precautionary registration measure that serves two functions:

• Document the volume and value of all Chinese lysine imports entering the EU from the date of entry into force.
• Enable retroactivity: if the anti-dumping investigation concludes with the imposition of definitive duties, these may be applied to imports registered during the investigation period, not just future ones.

Importing companies must declare and document their operations to Spanish and European customs authorities throughout the registration period. Failure to register does not generate a direct penalty described in this regulation, but it has a relevant practical consequence: it could prevent the correct retroactive application of duties, also generating legal uncertainty about the operation.

The registration mechanism is a common tool in EU trade policy in anti-dumping investigations. Its activation indicates that the Commission considers there is sufficient evidence of dumping practices by Chinese lysine exporters to justify caution.

Economic and operational impact

The economic impact of this regulation has two dimensions that must be managed simultaneously:

• Uncertainty in the final cost of imports: Any batch of Chinese lysine imported from July 28, 2026 may be subject to additional anti-dumping duties if the investigation concludes favorably for the European industry. The amount of those duties is not determined in this regulation, as it depends on the outcome of the investigation.
• Risk of retroactive cost: Unlike an ordinary tariff that only affects future imports, the registration mechanism allows duties to be applied to operations already carried out during the registration period. This means that a company importing lysine today could receive an additional invoice months later.
• Impact on the livestock value chain: Lysine is a critical input in feed formulation for poultry and pigs. An increase in the cost of this amino acid is passed directly to the production cost of livestock farmers and, ultimately, to the price of meat.
• Pressure on supply contracts: Contracts signed before July 28, 2026 without price adjustment clauses could become a problem if anti-dumping duties materialize and the importer cannot pass them on to the customer.

Who does it affect?

• Direct importers of lysine from the People's Republic of China established in Spain or any other EU Member State.
• Compound feed manufacturers that use Chinese lysine as a raw material or additive in their formulations.
• Agri-food and livestock companies that purchase feed with lysine or that directly import this amino acid for their own use.
• Traders and distributors of raw materials for animal nutrition operating with Chinese origin.
• Purchasing and logistics departments of agri-food groups with sourcing in Asia.

Practical example

A Spanish feed manufacturing company imports 500 tonnes of Chinese lysine per month for its production plant. From July 28, 2026, each of these imports must be declared and registered with customs.

If the anti-dumping investigation concludes, for example, six months later with the imposition of definitive duties, the Commission could apply those duties retroactively to the 3,000 tonnes imported and registered during that period. The additional cost would depend on the percentage of tariff set, which in European anti-dumping investigations can vary widely depending on the calculated dumping margin.

If that company has not incorporated in its contracts with customers an adjustment clause for anti-dumping duties, it will have to absorb that additional cost in its margin. That is why immediate contract review is the most urgent action.

What should companies do now?

1. Verify if you import Chinese-origin lysine: Review your supply chain and identify if any supplier, direct or indirect, has origin in the People's Republic of China. Also include intermediate suppliers that may be re-exporting from third countries.
2. Comply with customs registration from July 28, 2026: Ensure that all Chinese lysine imports are correctly declared to customs authorities. Coordinate with your customs agent or foreign trade department to ensure proper documentation.
3. Review current supply contracts: Incorporate price adjustment clauses that allow you to pass on any anti-dumping duties to customers. If contracts are already signed without that clause, negotiate an amendment urgently.
4. Evaluate alternative sourcing options: Analyze whether there are lysine suppliers in other countries (outside China) that can cover part of the volume as a hedge against possible price increases from Chinese origin.
5. Monitor the anti-dumping investigation: The European Commission will publish the progress of the investigation in the EU Official Journal. Monitor publications to anticipate the final decision.
6. Consult with a foreign trade specialist: If the import volume is significant, advice from an expert in customs and anti-dumping regulation can help you minimize economic impact and properly manage regulatory compliance.
