China's Ministry of Commerce (MOC) announced Monday that it will maintain anti-dumping measures on some imported polyvinylchloride (PVC) from Sept. 29.

The anti-dumping measures target PVC, one of the most widely used materials in the chemical industry, imported from the United States, the Republic of Korea, Japan and Russia.

According to the ministry, the period will be five years.

China launched anti-dumping measures on PVC from those countries in 2003 for a period of five years, and launched an investigation into ending of the measures in September 2008.

The MOC said that if China suspended anti-dumping measures on the material, the domestic industry would continue to be harmed.

The country's importers should pay anti-dumping taxes to customs departments when importing such products, said the MOC.

The product from Taiwan is also among the mainland's anti-dumping list.
