Apr 13, 2005. /Lesprom Network/. Australia has put the brakes on South Korean exports of grey-back carton board by slapping preliminary anti-dumping tariffs on the packaging material, a trade promotion agency here said Wednesday. The dumping margin rates determined by the Australian authorities for the duplex board were 16% for Daehan Pulp Co. and 31.7% for other companies, according to the Korea Trade-Investment Promotion Agency. South Korean companies paid a 5-percent tariff to Australia for the paper products before the anti-dumping regulation. The Australian authorities imposed tentative anti-dumping tariffs on the South Korean paper from Saturday, with a final ruling by the Australian government scheduled for May 19. South Korea sent US$6 million worth of the product to the antipodean country last year, accounting for 90% of all the carton board imports, yet strong local supply limited Korean firms' share of the Australian market to 10%. Out of 46 anti-dumping cases in Australia, 10 have involved South Korean products. South Korea has been the focus of more Australian anti-dumping actions than any other country. "We will discuss the matter, including the recent anti-dumping action against the carton board, with the Australian government soon, maybe at the bilateral trade meeting in May," said Kang Won-joon, deputy director in charge of anti-dumping matters at the Ministry of Foreign Affairs and Trade.
