According to a Reuters report, the European Union on Tuesday said it will impose tariffs on Chinese aluminium extrusion midway through an investigation into whether manufacturers from China are selling at unfairly low prices.

The duties will range from 30.4 to 48.0% and will apply from Wednesday. The EU will apply the tariffs until the investigation’s expected completion by April.

Other “cooperating” companies will see duties of 34.9% and material from all other companies will see tariffs of 48%.

In February, the European Commission started an investigation into the product widely used in transport, construction and electronics following a complaint from industry body European Aluminium.
