The Anti-dumping Commission has accepted an application from Australian tower manufacturer Keppel Prince to look into the pricing of goods from China and Korea that are claimed to be below retail prices in their own countries.
Keppel Prince has been pushing to have the situation investigated for a year and is calling for a 44% tariff to be charged on overseas turbine parts.
In June the manufacturer won a contact for 51 towers at the Taralga wind farm in New South Wales after the region's green project bank, the Clean Energy Finance Corporation, covered the difference between the price of local towers and those from overseas.
In 2012 the company, Australia's largest tower producer, announced it was seeking up to 100 voluntary redundancies from the 450 staff at its Victoria plant due to a fall in orders.
The commission said it will make a decision on whether to impose the tariff by the end of January.
