The EU is to apply a 42.1% anti-dumping duty on Chinese solar glass manufacturers, according to a document published in the organisation's official journal.
The new levies are applicable from tomorrow, 28 November, the day after publication in the journal.
The investigation was announced in February this year with a parallel anti-subsidy inquiry following in April.
Companies that cooperated with the EU investigation will be charged slightly lower rate of 38.4% with Henan Yuhua given the lowest rate of 17.1% to reflect its smaller dumping margin. Hehe Group was given a 32.3% levy and Xinyi Group a 39.3% rate.
The EU believes that the duties could allow manufacturers that ceased production due to price pressure from an influx of low-cost Chinese solar glass to begin again.
Centrosolar sold its glass manufacturing arm to Belgian firm Ducatt for a nominal fee in May after it starting losing money in 2012.
