It follows an application by Australian company BlueScope Steel Limited, according to a statement from Australia’s Anti-Dumping Commission (ADC).
The application alleged that the goods, aluminum zinc coated steel of 600 millimeters width or more, have been exported from Vietnam, South Korea and Taiwan at less than their normal prices.
It also said that the products from Vietnam received countervailable subsidies. This has undercut Australian steel and reduced profits for manufactures there, the application said.
Vietnamese exporters are invited to complete a questionnaire and submit revelation information to Australia by August 6, and have been advised by trade authorities to comply.
