Chinese adipic acid antidumping tariff 2026: what importers must do

Key data

Importers of adipic acid from China have been operating since May 2026 under a regime of definitive antidumping duties established by Commission Implementing Regulation (EU) 2026/913. Now, the European Commission publishes a correction of errors to that regulation, with reference OJ:L_202690685, which requires a review of the application of those duties in ongoing and future customs operations.

Adipic acid is a critical industrial raw material: it is used in the manufacture of nylon (polyamide 6,6), polyurethanes, plasticizers and other compounds. China is one of the world's leading exporters of this product, which explains the opening of the antidumping procedure by the Commission to protect European manufacturers.

What does this regulation establish?

Commission Implementing Regulation (EU) 2026/913, published on 5 May 2026, established two simultaneous measures on imports of adipic acid originating from China:

• Definitive antidumping duty: permanent tariff applicable to imports of the product from China.
• Definitive collection of provisional duty: consolidation of provisional duties already applied during the investigation phase, which become definitively enforceable.

The correction of errors published on 11 August 2026 adjusts technical or formal aspects of the original regulation. The substance of the protectionist measure is not altered: the antidumping duties remain in force and are mandatory. The correction does not specify a new differentiated entry into force date.

This type of correction is common in European regulations when errata, incorrect references or imprecisions in the wording of the original text are detected. Its practical effect is that the corrected version prevails over the original for all legal and customs purposes.

Economic and operational impact

For importers of Chinese adipic acid, the impact is direct: the cost of imports increases with the definitive antidumping duty on the CIF price of the goods. The technical correction requires a review to ensure that customs settlements already made since 5 May 2026 have been calculated correctly in accordance with the corrected version.

For European adipic acid manufacturers, the measure represents a competitive advantage: the antidumping tariff increases the price of Chinese product and levels the playing field against imports that, according to the Commission's investigation, were being produced at dumping prices.

Industrial sectors that use adipic acid as a raw material—nylon, polyurethane and plasticizer manufacturers—face an increase in procurement costs if they relied on Chinese supply, which may pressure their margins or force a review of the supply chain.

Who does it affect?

• Direct importers of adipic acid originating from China: must apply the corrected definitive antidumping tariff in all their customs declarations.
• European chemical industry: both those competing with the Chinese product (benefited) and those using it as an input (harmed by higher costs).
• Nylon manufacturers (polyamide 6,6): adipic acid is one of the two main monomers for its production.
• Polyurethane manufacturers: use adipic acid in the synthesis of polyester polyols.
• Plasticizer manufacturers: use adipic acid as a raw material in plasticizer esters.
• Purchasing and logistics departments: of any industrial company that purchases adipic acid of Chinese origin, directly or indirectly.
• Customs agents and logistics operators: responsible for managing import declarations of the product.

Practical example

A Spanish nylon manufacturing company that regularly imports adipic acid from China through a customs agent must act on two fronts:

1. Verify settlements since May 2026: all import declarations submitted since 5 May 2026 must have been calculated with the definitive antidumping duty. Now, with the correction published on 11 August, the customs agent must confirm that the data applied match the corrected version of Regulation (EU) 2026/913.
2. Update internal procedures: if the company has templates or import cost calculation systems based on the original regulation, it must update them with the corrected version to avoid errors in future operations.

If the correction affects, for example, the identification of the product code or the calculation of the applicable duty rate, an incorrect declaration could result in a supplementary settlement by Customs, with corresponding surcharges and interest.

What should companies do now?

1. Download and review the corrected version of Regulation (EU) 2026/913 published in the EU Official Journal with reference OJ:L_202690685. Identify exactly what technical or formal aspects have been corrected.
2. Review all customs declarations submitted since 5 May 2026 to verify that the antidumping duties applied comply with the corrected version. If discrepancies are detected, contact the customs agent to assess the need for rectification.
3. Update import cost calculation systems with data from the corrected version, especially if spreadsheets or ERP systems with manually configured tariff parameters are used.
4. Inform the purchasing department about the impact on the cost of Chinese adipic acid and assess whether it is necessary to review supply contracts or seek alternative suppliers outside China to reduce the tariff burden.
5. Consult with a foreign trade or customs specialist if there is uncertainty about the correct application of the corrected antidumping duties, especially if there are ongoing or pending import operations.
