China's Ministry of Commerce (MOC) announced it will begin a review of the nation's imported polyvinyl chloride (PVC) policies as anti-dumping measures are due for renewal.

The review comes at the request of domestic PVC companies and seeks to evaluate whether dumping or damages to the domestic industry will recur if the anti-dumping measures were terminated against PVC imports from the United States, the Republic of Korea, Japan, Russia as well as China's Taiwan, the MOC said in a statement Monday.

The review will begin on Sept. 29 and end before Sept.28, 2015.

A five-year anti-dumping tax on the PVC imports started on Sept.29, 2003. In 2008, the MOC decided to renew the anti-dumping measures for another five years after a sunset review.
