EU: Extension of Antidumping Duty on Cast Iron Pipe Fittings from China — March 24, 2026

Key Information

On March 24, 2026, the European Commission adopted Implementing Regulation (EU) 2026/709, extending the definitive antidumping duty against the People's Republic of China. This duty, initially applied to threaded malleable cast iron and spheroidal graphite cast iron pipe fittings via Regulation (EU) 2025/1890, now also covers non-threaded, molded malleable cast iron pipe fittings originating from China.

Key Points

• March 24, 2026: extension of the antidumping duty to non-threaded products
• Reference: Implementing Regulation (EU) 2026/709, published in the OJEU
• Industry stakeholders must adapt import customs declarations to this new tariff line

Background and Implications

The European Commission is strengthening its trade defense mechanism against the dumping of certain products originating from China. Following investigations on imports of molded malleable cast iron pipe fittings, the scope of the existing antidumping duty (Regulation EU 2025/1890) is expanded by Regulation (EU) 2026/709. This text imposes the same measures on imports of non-threaded products as those applied to threaded ones, to prevent circumvention practices and ensure fair competition in the European market. The relevant CN codes for the affected products are specified in the regulation's annexes.

Impact for the Industry

Customs declarants and freight forwarders must ensure application of the antidumping duty on all non-threaded malleable cast iron fittings originating from China, in addition to already covered products. Importers need to review their customs declarations and origin documentation to mitigate any compliance risks. Adhering to the correct tariff classification becomes crucial to avoid penalties and regularizations. Compliance officers should update internal procedures and inform teams regarding the expanded duty scope.

Next Steps

The regulation applies from March 25, 2026. Professionals are advised to:

• Audit relevant import flows
• Update ERP and customs systems with the affected CN codes
• Raise awareness among customs declaration teams and clients about this measure Enhanced verification is expected at customs clearance for the relevant tariff line.
