Antidumping Duties on Fiberglass Fabrics from China and Egypt: What Changes in 2026

Key data

European importers of fiberglass fabrics from China and Egypt must review their antidumping duties following the publication, on 8 April 2026, of a correction of errors affecting Commission Implementing Regulation (EU) 2022/1233. This correction may alter the rates each company pays at customs, the products included, or the data of affected companies.

Commission Implementing Regulation (EU) 2022/1233 previously amended Commission Implementing Regulation (EU) 2020/492, which imposed definitive antidumping duties on these materials. A correction of errors in this type of regulation is not a minor change: it may mean that the tariff rate your company has been applying was not correct, with the economic and customs consequences that entails.

What does this regulation establish?

Antidumping duties are additional tariffs that the European Union imposes on imported products at artificially low prices, with the aim of protecting European manufacturers from unfair competition. In this case, the affected products are knitted and/or sewn fiberglass fabrics originating from China and Egypt.

The regulatory chain governing these tariffs is as follows:

The corrections may affect three specific areas, based on available information:

• Applicable tariff rates: the percentage of antidumping duty applicable to each company or product may have been corrected.
• Product descriptions: the technical description of fabrics included in the scope may have been adjusted.
• Data of affected companies: the names, codes, or identifying data of manufacturers or exporters subject to individual rates may have changed.

The entry into force date of this correction has not been specified in the publication. It is recommended to consult directly the official source on EUR-Lex to confirm this information.

Economic and operational impact

A correction of errors in antidumping duties has direct consequences on supply costs. If the tariff rate applied so far was incorrect, the importing company may face:

• Additional tariff payments if the correct rate is higher than the one being applied.
• Possible claims or adjustments to customs declarations already submitted.
• Review of purchase contracts with Chinese or Egyptian suppliers if the actual cost of importation changes.

The sectors with the greatest exposure are those that use fiberglass fabrics as raw materials or components in their production processes. The impact on costs will depend on the import volume of each company and the specific tariff rate resulting from the correction.

From an operational perspective, companies must update their tariff classification systems and communicate changes to their customs agents to avoid errors in future import declarations.

Who does it affect?

• Direct importers of knitted and/or sewn fiberglass fabrics from China or Egypt.
• Construction sector manufacturers that use these fabrics as reinforcement in composite materials, panels, or insulation.
• Automotive sector companies that use fiberglass in structural or body components.
• Composite and composite materials manufacturers that source fiberglass fabrics as primary raw materials.
• Customs agents and logistics operators that manage imports of these products for their clients.
• Foreign trade advisors and CFOs responsible for managing tariff costs in industrial companies.

Practical example

A composite panel manufacturing company for construction regularly imports sewn fiberglass fabrics from a supplier in China. Until now it applied the antidumping tariff rate included in Commission Implementing Regulation (EU) 2022/1233 according to its supplier's data.

Following the publication of this correction of errors on 8 April 2026, the purchasing manager or CFO must verify whether their Chinese supplier's data appears among the corrected data, whether the description of the product they import still corresponds to the same tariff heading, and whether the tariff rate applied to them has changed. If the correct rate turns out to be higher than the one applied, the company will need to adjust its import costs and review whether there are pending settlements with customs. If the rate is lower, the company could be entitled to a refund.

The same analysis applies to any company importing these materials from Egypt, as both origins are covered by the same corrected regulation.

What should companies do now?

1. Access the official correction on EUR-Lex and read the full text to identify exactly what data has been corrected: tariff rates, product descriptions, or company data.
2. Verify whether your Chinese or Egyptian supplier appears in the corrected data, as antidumping rates are usually individual by exporting company. A change in your supplier's data directly affects you.
3. Check that the tariff classification of the products you import remains correct following the corrections to product descriptions.
4. Communicate the changes to your customs agent so they update the parameters of your import declarations and avoid errors in future operations.
5. Review recent customs declarations with your foreign trade advisor to assess whether it is necessary to submit corrections or claims to customs.
6. Update supply cost models if the applicable tariff rate has changed, to reflect the actual impact on the purchase price of materials.
