EU Definitive Anti-Dumping Duty 2026/586 on Chinese Phosphorous Acid

Key Information

On March 17, 2026, the European Commission adopted Implementing Regulation (EU) 2026/586. This regulation establishes a definitive anti-dumping duty and confirms the definitive collection of the provisional duty on imports of phosphorous acid originating in the People’s Republic of China.

Key Points

• The definitive anti-dumping duty applies from its publication in the OJEU on March 17, 2026.
• Reference text: Implementing Regulation (EU) 2026/586 of the Commission, OJEU L_202600586.
• Declarants, importers, and freight forwarders must apply this new duty to all relevant imports.

Background and Issues

Implementing Regulation (EU) 2026/586 follows an anti-dumping investigation procedure initiated against phosphorous acid imported from China. Phosphorous acid (the specific tariff heading is indicated in the regulation) is subject to dumping practices that are likely to harm European producers. The definitive anti-dumping duty replaces the provisional duty previously applied during the investigation. This measure falls within the framework of the Union Customs Code (UCC) and the EU’s trade defense regulations (articles 56 and 57 UCC, Regulation (EU) 2016/1036 on protection against dumped imports).

These measures strengthen the protection of the European chemical industry and require immediate adaptations from the sector. Phosphorous acid is a strategic input for many sectors (agri-food, chemical industries, fertilizers).

Impact for Industry Professionals

Declarants must rigorously classify goods under the tariff heading specified by the regulation. Importers must verify product origin and calculate the definitive anti-dumping duty in their customs declarations. Freight forwarders are responsible for ensuring correct application of the duties. Compliance officers must update internal procedures and inform their subsidiaries and partners of the new regulatory obligations.

The risk of litigation for non-compliance with the anti-dumping duty is heightened, especially during subsequent customs audits. All import operations of Chinese phosphorous acid are affected.

Next Steps

• Immediate application date: March 17, 2026 (OJEU publication).
• Professionals should consult Regulation (EU) 2026/586, freely accessible on EUR-Lex.
• Timely update of declaration tools and internal tariffs is recommended upon entry into force.
• Customs authorities will conduct increased surveillance during upcoming importations.

Depuis le 17 mars 2026, les importations d’acide phosphoreux chinois sont soumises a un droit antidumping definitif par l’UE.
