The European Commission is considering opening an investigation into imports of certain construction materials from several Balkan countries over suspicions that they were made using low-cost Chinese glass fibre already subject to EU anti-dumping duties, according to people familiar with the matter.

The probe will focus on so-called open mesh fabrics, including thermal insulation systems.

The case comes as the European Commission continues to step up pressure on low-cost Chinese imports, which are contributing to the EU's record-high €1 billion-a-day trade deficit with China. The commission launched negotiations with Beijing in June in a bid to rebalance trade ties, with hopes of securing tangible results by October.

EU Trade Commissioner Maroš Šefčovič expected to travel to China in October.

At the same time, the Commission has warned that it would deploy its trade defence instruments before the deadline to counter low-cost Chinese imports, arguing that China uses unfair practices to gain access to the EU market – including strategies to circumvent EU tariffs.

Open mesh fabrics are often manufactured with Chinese glass fibre, which the Commission has accused Chinese producers of selling at unfairly low prices on the EU market, causing injury to European manufacturers. The EU has targeted glass fibre with additional duties several times in recent years, including imports from Egypt that are produced by Chinese companies.

But Chinese producers are suspected of circumventing those anti-dumping and anti-subsidy duties by relying on local manufacturers in several Balkan countries to assemble open mesh fabrics using low-cost Chinese glass fibre.

The EU produces around 1 million tonnes of melted glass annually from installations operating in eight countries, among them Germany, France and Italy.

But according to Glass Fibre Europe, which represents the glass fibre industry in Brussels, Chinese glass fibre overcapacity exceeds 100 percent of total EU market demand, raising the risk of further harm to European producers unless the EU strengthens its trade defence measures.

Over the past year, the number of cases involving alleged Chinese unfair trade practices across several industrial sectors has increased, and the Commission has been criticised for the length of its investigations.

At a summit in mid-June, EU leaders gave the Commission a mandate to review and update its trade defence instruments.

But the EU's current trade regulation toolbox remains limited, with Commission only able to address unfair trade practices on a product-by-product basis. Additional safeguard measures – including tariffs and quotas – are also under consideration, Euronews has learned, to protect the European chemicals sector from intense Chinese competition.

The Commission was contacted for comment but did not reply.
