A European Union official says the union has imposed duties on aluminum products imported from China after an investigation showed that they were being sold at unfairly low prices.

A report on Reuters said that the European Commission, which oversees trade policy for the 27-nation European Union, has set anti-dumping duties of between 21.2% and 31.2% on Chinese producers of aluminum extrusions in the form of bars, rods, profiles, or tubes.

It said that tariffs are lower than the provisional duties of 30.4% to 48.0% imposed midway through the investigation.

According to Reuters, the Commission opened an investigation in February 2020 into the products widely used in transport, construction, and electronics after a complaint from industry body EuropeanAluminium.

The report cited that members of European Aluminium include Norsk Hydro, Rio Tinto, and Alcoa.

It noted that duties of 21.2% are imposed for Guangdong Haomei NewMaterials Co Ltd and Guangdong King Metal LightAlloy Technology Co Ltd, while Press Metal International Ltd will see duties of 25.0%.

Reuters reported that "Other “cooperating” companies would face duties of 22.1% and material from all other companies would see charges of 32.1%.

China’s metals association had previously called the complaint groundless.
