The expected date for the KTC to issue its final conclusion has extended to August 27 this year, as the investigating agency needs more time to consider additional information related to manufacturers and importers.
According to the Trade Remedies Authority of Viet Nam, the investigation began on October 29, 2021, with a preliminary conclusion issued on April 22, 2022.
The preliminary conclusion determined that the dumping margin of Vietnamese enterprises was from 10 to 14.78 percent and Chinese firms from 15.95 to 42.03 percent.
However, the KTC recommended not applying temporary measures in this case because there were no clear signs that the imported goods caused significant damage to the domestic industry.
As of the end of 2020, seamless cooper pipes from China and Viet Nam had accounted for about 30 percent of the Republic of Korea's market, trailing a share of 60 percent by domestically-produced goods, according to the KTC.
