The European Union (EU) is moving ahead with tariffs on imported Chinese solar panels in an effort to protect its own module makers.

European Commission (EC) Trade Head Karel De Gucht will recommend the EC impose anti-dumping (AD) charges similar to those imposed last year by the U.S., according to Reuters.

The tariffs will average 47.6 percent for most of the 100-plus Chinese manufacturers found by the EC to have been involved in the dumping but will vary by the extent of the manufacturer’s dumping and the extent of their cooperation with the EC’s investigation, according to the Wall Street Journal, which reviewed the preliminary document.

Suntech Power Holdings (NYSE:STP) and its subsidiaries will be charged tariffs of 48.6 percent, LDK Solar (NYSE: LDK) will pay 55.9 percent, Trina Solar (NYSE:TSL) will pay 51.5 percent, and JinkoSolar (NYSE:JKS) will pay tariffs of 58.7 percent, WSJ reported. Companies that did not cooperate with the EC investigation will pay a tariff of 67.9%.

The investigation covered EU imports of crystalline silicon photovoltaic (PV) panels, cells, and wafers valued at $27.6 billion in 2011, which amounted to more than half the global PV market, according to Bloomberg. The Chinese companies, Bloomberg added, owned almost no global PV market share in 2004 but controlled 80 percent of the global market by 2011.
