Brussels tightens scrutiny over possible tariff circumvention.
Brussels, August 2026
The European Commission has launched a formal investigation into suspected trade practices involving fiberglass products manufactured by Chinese companies and routed through Balkan countries in an alleged attempt to bypass European trade defense measures. The inquiry focuses on whether production or transshipment operations outside China have been used to avoid anti-dumping duties imposed on Chinese fiberglass entering the European market.
Fiberglass is a strategic industrial material widely used in wind energy, construction, automotive manufacturing, aerospace and advanced composite technologies. European manufacturers argue that artificially low-priced imports have distorted competition for years, placing significant pressure on domestic producers and threatening investment throughout the bloc’s industrial supply chain.
Investigators will examine whether manufacturing activities carried out in third countries constitute genuine industrial production or merely represent assembly or logistical operations designed to alter the declared origin of the products before they enter the European Union. If authorities determine that existing trade measures have been deliberately circumvented, Brussels could extend anti-dumping duties to additional countries or companies involved in the supply chain.
The case reflects the European Union’s broader effort to strengthen trade enforcement as global manufacturing networks become increasingly complex. Companies seeking to reduce costs frequently relocate portions of production across multiple jurisdictions, making it more difficult for regulators to distinguish legitimate international investment from practices intended to evade commercial restrictions.
The investigation also carries geopolitical significance. As economic competition between the European Union and China intensifies, Brussels has expanded its use of trade defense instruments to protect strategic industries from what it considers unfair competition resulting from state subsidies, market distortions and pricing practices that disadvantage European manufacturers.
The outcome of the investigation could influence future European trade policy well beyond the fiberglass sector. A finding of circumvention would reinforce the Commission’s determination to close regulatory loopholes and increase oversight of global supply chains, particularly where products originating in China reach the European market through intermediary countries.
