India, South Korea, Taiwan and Saudi Arabia are among the countries suspected of dumping fibre.

The Indonesian Synthetic Fibre Makers Association says it is currently carrying out investigations into the allegations.

And it says it will file a formal complaint with the Indonesian Anti-Dumping Committee next year.

Under the World Trade Organisation regulations, an exporting company is liable to undergo an investigation if it holds more than three per cent of the import share in importing countries.

 The Indonesian Synthetic Fibre Makers Association said the countries are suspected of dumping polyester staple fibre, polyester filament yarn and nylon filament yarn.

Indonesian producers have been the target of anti-dumping laws in other countries. Anti-dumping duties have been imposed in the EU and the Turkish and Indian governments.
